The Most Versatile VoIP Provider: FREE PORTING

Mastering the Incredible PBX 16-15 Feature Set with Raspbian

blank

This week we’ll finish up our introduction of Incredible PBX® 16-15 for the Raspberry Pi with a quick look at some of the additional features that are offered on this new platform and that were not covered in our first and second articles. These include text-to-speech apps for news, weather, and today in history as well as the sample ODBC apps for speed dialing and employee data base lookups. We’ll also walk you through the conferencing setup and document the easiest way to deploy an Interactive Voice Response (IVR) system or a Stealth AutoAttendant with or without Direct Inward System Access (DISA) which provides a way to call into your PBX from anywhere and obtain dial tone to make calls or access features just as if you were using a local phone connected to your PBX. We’ll finish up with a review of the Incredible PBX security model: Travelin’ Man 3 IPtables firewall, Fail2Ban, and PortKnocker.

Introduction to Incredible PBX TTS Apps

Text-to-Speech (TTS) applications are included in Incredible PBX for two reasons. First, they provide useful information by phone. Second, they document the procedure required to build your own TTS applications using Asterisk®. That process typically includes a dialplan code addition to /etc/asterisk/extensions_custom.conf plus a PHP/AGI script which must be stored in /var/lib/asterisk/agi-bin. The actual interaction with the caller is handled in the dialplan code using a TTS engine to convert the text results of the PHP/AGI query into audio suitable for playback over the telephone. The (free) PicoTTS engine is included in the Incredible PBX image for the Raspberry Pi. The commercial IBM TTS engine is also available.

The job of the dialplan code is to answer the incoming call and prompt the caller for any necessary information that needs to be passed to the PHP/AGI script to obtain the information sought by the caller. For example, with the Weather by ZIP code app, the caller dials Z-I-P (947) and the dial plan code prompts the caller for the ZIP code of the desired weather report. This ZIP code is then passed to the nv-weather-zip.php AGI script to retrieve the requested weather forecast. The text results of the query then are passed back to the dialplan code which plays back the results to the caller using the PicoTTS engine.

Three sample TTS applications are included. Dial 951 for the latest Yahoo News headlines. Dial 947 to obtain a weather report for any American city using its ZIP code. Dial T-O-D-A-Y to listen to Today in History events for the current day of the year.

Introduction to Incredible PBX ODBC Apps

As with TTS apps, sample ODBC apps are included in Incredible PBX to provide useful information to callers and to document the procedure required to build your own ODBC applications with Asterisk. For those unfamiliar with ODBC, it is a middleware component that lets you build generic database applications that will work with almost any data base management system. In our case, we are using the MySQL clone, MariDB, as the backend database. But the same ODBC API could be used with a database stored in SQLite, or SQL Server, or PostgreSQL. To interact with your own database, the first step is to install an ODBC connector for your particular database so that it can "talk" to Linux and to Asterisk. On the Linux side, take a look at /etc/odbc.ini for examples of how this is done for individual databases. If you’re using a backend database other than MySQL/MariaDB, then the driver must be installed and added to /etc/odbcinst.ini. On the Asterisk side, there are three pieces that need to be put in place in /etc/asterisk. res_odbc_custom.conf houses the actual linkages to the ODBC databases defined in /etc/odbc.ini. func_odbc.conf houses the actual ODBC queries that will be used to read and write information from and to your databases. Finally, odbc.conf contains the dialplan code that will be used to interact with the caller. It answers the incoming calls, prompts the caller for necessary data to complete the query, executes the query defined in func_odbc.conf, and then converts the text results to audio and passes the results back to the caller using the PicoTTS app.

Two sample ODBC applications are included. Dial 222 to obtain an employee name lookup from the employee timeclock database by entering the employee number, e.g. 12345. Dial 223 for a speed dial application using the AsteriDex dialcode (the first 3 letters of a name). For example, enter D-E-L to obtain phone number of Delta Airlines and optionally place the call.

Introduction to Incredible PBX Conference Bridge

The Incredible PBX platform includes a preconfigured conference application which makes it easy for two or more parties to confer regarding any subject matter of common interest. Those with a local extension on the PBX can join the conference by dialing C-O-N-F (2663). For callers outside the PBX to participate, you would need to add a DID that points to the conference number. We’ve made it easy by including this option in the sample IVR created by Allison Smith. Simply designate the IVR as the destination for a DID and tell users to choose option 2. Local users can call D-E-M-O (3366) and choose option 2.

Before using the conference application, you will want to reset the conference passwords. There’s one for users and a second one for the conference leader. After logging into your server as root, issue the command: ./reset-conference-pins. You can display most of the passwords on your PBX including the conference PINs: ./show-passwords.

blank

The conference bridge setup is configured in the GUI: Applications -> Conferences. Here you can decide whether to require the conference administrator to be present before users can join the conference, you can force termination of the conference when the admin leaves, you can enable the menus for users and administrators by pressing *, you can choose whether to record the conference, you can set the maximum number of conference participants, and much more. Simply click on the ? icons for explanations of the various features. CAUTION: Be advised that saving new settings for the conference bridge will reset the conference PINs to the entries shown or entered into the template, e.g. 1234 and 4321 as shown above!

Configuring Incredible PBX IVRs and AutoAttendants

We’ve included a sample IVR and the Stealth AutoAttendant as part of the Incredible PBX install. The easiest way to master the process of building these is to examine the included samples and try them out: Applications -> IVR -> DemoIVR. The demo IVR comes with all the options preconfigured. Be very careful exposing this through a DID unless you have hardened the passwords, especially for the Telephone Reminders app since this application allows any caller to set up calls to external phone numbers which may cost you money!

The IVR options themselves are self-explanatory and well-documented under the ? icon. The IVR Entries at the bottom of the template define the destinations for caller button presses during a call. The Stealth AutoAttendant is worth examining further since it does not include predefined destinations. You would need to add these yourself. The idea behind a Stealth AutoAttendant is to provide options to a caller which are not explained when the AutoAttendant answers the call. In this way, it allows you to "hide" certain features of your PBX from the average caller. While standing alone, it’s obviously not secure since anyone can press a number on their phone after being connected, it does at least obscure the existence of the options. One good use for this is a DISA option which would let you call into your PBX to obtain dialtone to perform other functions on the PBX with an appropriate password, of course. This is documented in the next section and would need to be set up BEFORE adding the option as a choice on the AutoAttendant.

Configuring DISA with Incredible PBX

Before setting up a DISA option with Incredible PBX, be aware of the risks. Anyone that guesses your DISA password basically gets a blank check to perform any function that could be executed from any phone registered to your PBX. If you’ve decided to proceed anyway, access the GUI and choose Applications -> DISA -> Add DISA. Here’s what a typical DISA setup would look like. You’d obviously want a much more secure PIN!

blank

Once you have saved the template and reloaded your dialplan, you then can add DISA as an option in your IVR or AutoAttendant. Be sure to test it carefully before exposing it for public access. You’ve been warned!

Incredible PBX Security Model Overview

Unlike most other free PBX offerings, Incredible PBX is always deployed as a secure platform. Attempts to access Incredible PBX from outside your local area network will fail unless the IP address has been whitelisted in the IPtables firewall using one of the Travelin’ Man 3 utilities: add-ip or add-fqdn. Repeated attempts to access the PBX will be blocked by Fail2Ban and subsequent attempts to whitelist a blocked IP address will not be successful until the Fail2Ban quarantine expires. Thus, it is important to set up Incredible PBX initially using a desktop PC from which you will subsequently manage the PBX. This assures that at least this desktop PC’s IP address is whitelisted.

To whitelist a static IP address, log into your server as root and issue the following command: ./add-ip my-log-cabin 12.34.56.78 where my-log-cabin is the descriptive name you wish to associate with the whitelisted IP address and 12.34.56.78 is the actual IP address.

Obviously, everyone doesn’t have a static IP address. That’s what the add-fqdn utility is for. It allows you to use a dynamic DNS service to assign an FQDN to a dynamic IP address and rely upon the dynamic IP address provider to keep the FQDN synchronized as the IP address changes. Search your favorite search engine, search for "free dynamic dns raspberry pi" to find available providers. On the Incredible PBX, the setup is much the same except you’ll use the FQDN assigned to the IP address: ./add-fqdn my-log-cabin logcabin.myip.com. Incredible PBX actually runs a script every 10 minutes to keep dynamic IP addresses synchronized. Don’t make any changes to /root/ipchecker. If you’d prefer to have the script run more frequently, adjust the 10 entry in the ipchecker line in /etc/crontab.

Last but not least, Incredible PBX includes the PortKnocker utility which provides an emergency "back door" into your PBX if you ever find yourself locked out by the firewall rules. The idea behind PortKnocker is that you send a packet to three random, pre-defined ports in a particular sequence and, if there’s a match, PortKnocker whitelists your IP address for further access to the server until the firewall is restarted or the server is rebooted. You’ll find your credentials and documentation in /root/knock.FAQ. If your PBX is sitting behind a hardware-based router or firewall, be sure to map the three TCP ports to the LAN IP address of your PBX. Enjoy!

Icing on the Cake for Incredible PBX 16-15 and Raspberry Pi

blank

In our last article, we introduced Incredible PBX® 16-15 featuring Asterisk® 16 and FreePBX® 15 on the new Raspberry Pi 4 with Raspbian 10. But we’re just getting started. Today we want to show off the real power of this $35 on-premise platform with the addition of IBM’s voice recognition software. Your first 500 minutes a month are free. In conjunction with Incredible PBX, you’ll get flawless transcription and email delivery of your voicemail messages plus a voice dialer that lets you call anyone in your AsteriDex phonebook by simply dialing 411 and saying the name of the person or company you wish to call. We’ve got a few more surprises plus some tips for the $5.95 Blinkt rainbow light show that will have your friends drooling with envy. If you haven’t yet installed Incredible PBX 16-15, start there.

Configuring Gmail as Exim Smart Relay Host

Before you can receive voicemail messages by email, your server needs to be able to successfully send email messages. Most Raspberry Pi implementations will be on networks managed by companies like Comcast, Spectrum, and AT&T that block downstream mail servers (that’s you) from sending email. The solution is to use Gmail or your local ISP as a smart relay host to send mail from your server. Here’s how to set it up using a Gmail account without two-step authentication. Log into your server as root and run ./configure-exim-email. Choose "mail sent by smarthost; received via SMTP or fetchmail." Accept all the defaults until you get to Outgoing Smarthost prompt. Enter: smtp.gmail.com::587. At the following prompts, choose NO, NO, mbox, and NO. When the setup completes, edit /etc/exim4/passwd.client and insert the following line using your Gmail AcctName and AcctPW. NOTE: If you are using a Gmail account with 2-step verification enabled, you MUST use a Gmail App Key instead of your Gmail account password.

*.google.com:AcctName@gmail.com:AcctPW
smtp.gmail.com:AcctName@gmail.com:AcctPW

Save the file and then issue the following commands to complete the setup:

update-exim4.conf
systemctl restart exim4
exim4 -qff

Now send yourself a test email message to make sure things are working properly:

echo "test" | mail -s testmessage yourname@yourmailprovider.com

Some prefer an email notification whenever your server is booted. Once you have configured a relay host above, you can add this feature by editing /etc/rc.local and adding the following lines just above the service knockd start line using your actual email address:

_PRIVATE="Private IP: `cat /etc/hostip | cut -f1-2 -d " "`"
_PUBLIC=" Public IP: `curl -s -S --user-agent \\
"Mozilla/4.0" http://myip.incrediblepbx.com | awk 'NR==2'`"
echo "$_PRIVATE\\n$_PUBLIC" | mail -s "RasPi 16-15 has booted" yourname@yourmailserver.com


Obtaining IBM Cloud Speech to Text Credentials

Follow this link to set up your IBM account and obtain credentials for both Speech to Text (STT) and Text to Speech (TTS) services. Please note that your STT and TTS API keys will NOT be the same. So don’t accidentally use the wrong one. For today, we’ll need your STT API Key.

Installing STT Engine for Voicemail Transcription

Now we’re ready to deploy IBM’s STT Engine to (1) transcribe your voicemails and (2) deliver them by email. To begin, open the Incredible PBX web GUI with your browser and edit extension 701 under Applications -> Extensions. Click on the Voicemail tab. Enter an Email Address for delivery of your voicemails. Set Email Attachment, Play CID, and Play Envelope to YES. After testing things out, you may want to actually Delete Voicemails after email delivery, but leave it set to NO for the time being. Click Submit and Apply Config to save your settings.

Next, log into the Linux CLI as root and change to the /usr/local/sbin directory. Then copy the sendmailmp3.ibm file to sendmailmp3: Then edit sendmailmp3.

cd /usr/local/sbin
cp -p sendmailmp3.ibm sendmailmp3
nano -w sendmailmp3

Scroll down to line #21 and enter your actual API_KEY replacing the X’s inside the quotes. Save the file: Ctrl-X, Y, then ENTER. Now call extension 701’s voicemail (*701) and leave yourself a short voicemail message. Within a minute or two, it should be delivered to your email address that you specified for extension 701 voicemails. It will include the voicemail recording as well as a transcription.

Deploying the AsteriDex Voice Dialer

AsteriDex is an open source database that is included in every Incredible PBX deployment. You can access it within the web GUI under the Third Party Addon tab. By default, it includes entries for some of the major airlines. You can create as many additional entries as you wish. Also included with Incredible PBX is a voice dialer that is accessed by dialing 411. You’ll be prompted for the name of the person or company to contact. Once you say the name, the voice dialer will place the call using your default outbound route for 10-digit calls. The missing piece is voice recognition software to transcribe what you say into text that can be looked up in AsteriDex to retrieve the number to call. That’s where IBM’s STT engine enters the picture. To deploy it, start by replacing the 411 context in your dialplan. Then we’ll edit the getnumber.sh shell script and insert your STT credentials.

cd /var/lib/asterisk/agi-bin
sed -i '\:// BEGIN Call by Name:,\:// END Call by Name:d' \\
 /etc/asterisk/extensions_custom.conf
sed -i '/\[from-internal-custom\]/r /var/lib/asterisk/agi-bin/ibm-411.txt' \\
 /etc/asterisk/extensions_custom.conf
asterisk -rx "dialplan reload"
nano -w getnumber.sh

Scroll down to line #13 and make it look like this: API_USERNAME="apikey"

On Line #14, enter your actual API_KEY between the quotation marks replacing the X’s. Then save the file: Ctrl-X, Y, then ENTER.

Now pick up a phone connected to your PBX and dial 411. When prompted for the person/company to call, say "American Airlines."

Move Over Siri. Here Comes Iris.

If the idea of instant access to all the world’s information is appealing but you’re not quite ready to invite Siri, Alexa, and Google into your bedroom, then IRIS may be your cup of tea. With the Incredible PBX implementation of Wolfram Alpha, you simply dial I-R-I-S (4747) from any phone, ask a question, and the world’s greatest almanac tied to a supercomputer will provide you an answer. So long as it’s for non-commercial use, you get 2,000 free queries a month just by signing up for a Wolfram Alpha account. Here’s a sample of what’s available:

Weather in Charleston South Carolina
Weather forecast for Washington D.C.
Next solar eclipse
Otis Redding
Define politician
Who won the 1969 Superbowl? (Broadway Joe)
What planes are flying overhead now? (flying over your server’s location)
Ham and cheese sandwich (nutritional information)
Holidays 2019 (summary of all holidays for 2019 with dates and DOW)
Medical University of South Carolina (history of MUSC)
Star Trek (show history, air dates, number of episodes, and more)
Apollo 11 (everything you ever wanted to know)
Cheapest Toaster (brand and price)
Battle of Gettysburg (sad day 🙂 )
Daylight Savings Time 2019 (date ranges and how to set your clocks)
Tablets by Motorola (pricing, models, and specs from Best Buy)
Doughnut (you don’t wanna know)
Snickers bar (ditto)
Weather (local weather at your server’s location)

Deploying IRIS is simple. Once you have your Wolfram Alpha APP-ID, edit the 4747 file in /var/lib/asterisk/agi-bin and insert your APP-ID in the first line of the file. Then save it. In the same directory, edit wolfram.sh and enter apikey for your API_USERNAME, your actual IBM STT API key as your API_PASSWORD, and reenter your Wolfram Alpha APPID. Then save the file. Now dial I-R-I-S (4747) from any phone and ask one of the sample questions above.

UPDATE: A bug crept into the Wolfram Alpha scripts somewhere along the way. Here’s the fix, but you don’t need to install it. Simply log out and back into your Raspberry Pi as root, and the Automatic Update Utility will install it for you.

cd /var/lib/asterisk/agi-bin
sed -i 's|results.chr(13).chr(10);|results.chr(13).chr(10).chr(34);|' 4747.php

Using Allison’s Demo IVR for Feature Set Access

Rather than remembering all of the dial codes we’ve documented above, the easiest way to get instant access to all the features we’ve discussed plus more is to dial D-E-M-O (3366) from any phone connected to your PBX. Better yet, you can share the feature set with your friends by configuring the Demo IVR as the Inbound Route Destination for one of your DIDs. Be careful sharing your password for Telephone Reminders to avoid having some creep schedule multiple reminders to make expensive calls to some ship in the middle of nowhere.

Updating pbxstatus to Support NeoRouter

If you have deployed the NeoRouter VPN on your server, you’ve probably noticed that the pbxstatus display looks a bit awkward now since there are multiple local IP addresses. Here’s the fix. Edit /usr/local/sbin/pbxstatus. Scroll down to line #6 and replace it with the following. Then save the file.

_IP=" Private IP: `cat /etc/hostip | cut -f1-2 -d " "`"

Adding Blinkt for Non-Blacklisted Incoming Calls

If you deployed the Blinkt hardware addition following our last tutorial, we wanted to add an additional feature that will provide visual alerts when incoming calls arrive. Here’s how:

cp -p /root/rainbow.py /usr/local/sbin/.
echo "asterisk ALL = NOPASSWD: /usr/local/sbin/rainbow.py" >> /etc/sudoers
echo '[app-blacklist-check]
include => app-blacklist-check-custom
exten => s,1(check),GotoIf($["${BLACKLIST()}"="1"]?blacklisted)
exten => s,n,Set(CALLED_BLACKLIST=1)
exten => s,n,System(/usr/bin/sudo /usr/local/sbin/rainbow.py &)
exten => s,n,Return()
exten => s,n(blacklisted),Answer
exten => s,n,Set(BLDEST=${DB(blacklist/dest)})
exten => s,n,ExecIf($["${BLDEST}"=""]?Set(BLDEST=app-blackhole,hangup,1))
exten => s,n,GotoIf($["${returnhere}"="1"]?returnto)
exten => s,n,GotoIf(${LEN(${BLDEST})}?${BLDEST}:app-blackhole,zapateller,1)
exten => s,n(returnto),Return()
;--== end of [app-blacklist-check] ==--;
' >> /etc/asterisk/extensions_override_freepbx.conf
asterisk -rx "dialplan reload"

Back to School: It’s Incredible PBX 16-15 for the Raspberry Pi

blank

It’s Back to School Time in the U.S.A., and we have a terrific new August project for you and your shiny new Raspberry Pi 4. It features Asterisk® 16 with all the latest FreePBX® 15 GPL modules plus the feature sets of Incredible PBX® and RasPBX and RonR’s latest build. And it’s all rolled into one terrific (free) bundle. It’s literally the best of all worlds. Finally, a word of caution. This is a work in progress. If you’re looking for instant perfection, come back after Labor Day. But, if you want to roll up your sleeves and participate in an open source project, you’ve come to the right place. We welcome your comments AND contributions. After all, that’s what open source development is all about. Participate!

This is the first of several articles on Incredible PBX 16-15. Today, we’ll get your platform built and walk you through what’s included in the new build. You can expect a new release regularly until we work through all of the kinks and some of the missing pieces. If you’ve been following our articles this past month, you already know that restoring backups from Incredible PBX 13-13 into Incredible 16-15 was one of the primary development goals of FreePBX 15. It remains a little rough around the edges, but we’re close on the CentOS platform. And, in coming weeks, we’ll integrate what we’ve learned on the CentOS 7 platform into the Raspbian 10 Buster image for the Raspberry Pi. In the meantime, come enjoy and explore the powerful, new feature set that comes with Incredible PBX 16-15 out of the box. Unlike RonR’s build, there’s nothing to compile with Incredible PBX 16-15 for Raspbian 10 even though all of the components are there to let you do so whenever the mood strikes. And, unlike the FreePBX Distro, we don’t rely on static packages which make it difficult to make future modifications on your own. Instead, Incredible PBX 16-15 offers a snapshot image with a complete toolkit to make future modifications as desired.

What’s Included? Incredible PBX 16-15 for Raspbian 10 serves up a VoIP powerhouse featuring Asterisk 16 and all FreePBX 15 GPL modules, an Apache web server, the latest MariaDB SQL server (formerly MySQL), Exim4 mail server, and most of the Incredible PBX feature set including SIP, SMS, voice recognition, AsteriDex, PicoTTS Text-to-Speech VoIP applications plus fax support, Click-to-Dial, News, Weather, Telephone Reminders, and hundreds of features that typically are found in commercial PBXs: Conferencing, IVRs and AutoAttendants, Email Delivery of Voicemail, Voicemail Blasting, and more. We’ve also incorporated the Zero Trunk Configuration feature from the LITE build which lets you sign up with one of four VoIP providers and start making and receiving calls instantly.

Choosing a SIP Provider. As we mentioned, Incredible PBX 16-15 comes preconfigured to support four of the major SIP providers: Skyetel, VoIP.ms, V1VoIP, and Anveo Direct. We obviously hope you’ll choose Skyetel not only because they financially support Nerd Vittles and our open source projects, but also because it is a clearly superior platform offering crystal-clear communications and quadruple-redundancy so you never miss a call. Skyetel also sets itself apart from the other providers in the support department. They actually respond to issues, and there’s never a charge. As the old saying goes, they may not be the cheapest, but you get what you pay for. Even without taking advantage of Nerd Vittles free $10 credit plus a half-price offer on up to $500 of Skyetel services, they’re still dirt cheap compared to the Bell Sisters and cable companies. Traditional DIDs are $1 per month. Outbound conversational calls are $0.012 per minute. Incoming conversational calls are a penny a minute, and CallerID lookups are $0.004. With all four providers, you only pay for minutes you use. Using more than one is a good idea. With your Skyetel $10 credit, there’s ample funding to order a phone number and make hundreds of calls at zero cost. Once you’re satisfied with the service (and you will be), you can fund your account with up to $250, and Skyetel will match your deposit plus give you free number porting for any existing numbers you want to add to your account. Quite literally, you have nothing to lose. Effective 10/1/2023, $25/month minimum spend required.

    First Boot of Incredible PBX 16-15 with Wi-Fi

    Incredible PBX 16-15 requires Internet connectivity to complete its automated install. If you’re using a wired network connection, you can skip to the next section. With the Raspberry Pi 3B and 4B, WiFi is built into the hardware. But you still have to insert your SSID name and SSID password to make a connection to your WiFi network. To do so, follow these next steps carefully. Insert the Incredible PBX 16-15 microSD card into your Raspberry Pi 3 or 4 and apply power to the hardware. When the bootup procedure finishes, login as root with the default password: password. At the first prompt, DO NOT PRESS THE ENTER KEY! Instead, press Ctrl-C to break out of the setup script. At the command prompt, issue the following commands to bring up the WiFi config file:

    cd /etc/wpa_supplicant
    nano -w wpa_supplicant.conf
    

    If your WiFi network does not require a password, uncomment or insert the four lines below and save the file: Ctrl-X, Y, then Enter. Now restart your server: reboot. When the reboot finishes, you now should have network connectivity.

    network={
     key_mgmt=NONE
     priority=1
    }
    

    If your WiFi network requires a password, uncomment or insert the following into wpa_supplicant.conf:

    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
    update_config=1
    
    network={
     ssid="YourSSID"
     psk="YourSSIDpassword"
     key_mgmt=WPA-PSK
     scan_ssid=1
     priority=7
    }
    

    Then scroll down to the SSID entry and replace YourSSID with the actual SSID of your WiFi network. Make sure you preserve the entry with the quotes as shown. Next, replace YourSSIDpassword with the SSID password of your WiFi network. Save the file: Ctrl-X, Y, then Enter. Now restart your server: reboot. When the reboot finishes, you now should have network connectivity.

    Once the reboot process finishes, you should see an entry on about the middle line displayed on your monitor which reads: "My IP address is…". Write down the IP address shown. You’ll need it in a minute. Skip the next section since you are using a WiFi connection.

    If you don’t see an IP address assigned to your server, then correct the network deficiency (invalid WiFi credentials, DHCP not working, Internet down), and reboot until you see an IP address assigned to your server. DO NOT PROCEED WITHOUT AN ASSIGNED IP ADDRESS.

    First Boot of Incredible PBX Using Wired Connection

    Incredible PBX 16-15 requires Internet connectivity to complete its automated install. After connecting your server to your local network with a network cable, insert the Incredible PBX 16-15 microSD card into your Raspberry Pi and apply power to the hardware. When the bootup procedure finishes, you should see an entry on about the middle line displayed on your monitor which reads: "My IP address is…". Write down the IP address shown. You’ll need it in the next step.

    If you don’t see an IP address assigned to your server, then correct the network deficiency (cable not connected, DHCP not working, Internet down), and reboot until you see an IP address assigned to your server. DO NOT PROCEED WITHOUT AN ASSIGNED IP ADDRESS.

    Completing the Incredible PBX Initialization Procedure

    Unless your desktop PC and RasPi are both on the same private LAN, the remainder of the install procedure should be completed from a desktop PC using SSH or Putty. This will assure that your desktop PC is also whitelisted in the Incredible PBX firewall. Using the console to complete the install is NOT recommended as your desktop PC will not be whitelisted in the firewall. This may result in your not being able to log in to your server. Once you have network connectivity, log in to your server as root from a desktop PC using the default password: password. Accept the license agreement by pressing ENTER. You then will be redirected to raspi-config. This is the utility used to expand your Incredible PBX 16-15 image to use your entire microSD card. If you fail to complete this step, your microSD card will be restricted to 16GB. In the raspi-config utility, choose Localization Options and set Locale, TimeZone, Keyboard, & WiFi Country. Then choose Advanced Options. All of the defaults should be satisfactory with the exception of the first item: Expand Filesystem. Choose this option and activate the resizing directive. Review the other items and then exit and reboot.

    Once your server reboots and you log back in as root, all of your passwords will be randomly assigned with the exception of the root user Linux password and your admin password for access to the web GUI. You can set the root password by issuing the command: passwd. Set the admin password for access to the web GUI with this command: /root/admin-pw-change. With the exception of these two passwords, the remaining passwords can be displayed using the command: /root/show-passwords.

    Finally, if your PBX is sitting behind a NAT-based router, you’ll need to redirect incoming UDP 5060-5061 and UDP 10000-20000 traffic to the private IP address of your PBX. This is required for all of the SIP providers included in the Incredible PBX 16-15 build. Otherwise, all inbound calls will fail.

    Configuring Skyetel for Incredible PBX 16-15

    If you’ve decided to go with Skyetel, here’s the drill. Sign up for Skyetel service and take advantage of the Nerd Vittles Free $10 credit and BOGO special. First, complete the Prequalification Form here. You then will be provided a link to the Skyetel site to complete your registration. Once you have registered on the Skyetel site and your account has been activated, open a support ticket and request the $10 credit for your account by referencing the Nerd Vittles special offer. Once you are happy with the service, open another ticket after funding your account and request that Skyetel match your deposit of up to $250. That gets you up to $500 of helf-price calling. Credit is limited to one per person/company/address/location. If you have numbers to port in, you can do it at no cost after funding your account.

    Skyetel does not use SIP registrations to make connections to your PBX. Instead, Skyetel utilizes Endpoint Groups to identify which servers can communicate with the Skyetel service. An Endpoint Group consists of a Name, an IP address, a UDP or TCP port for the connection, and a numerical Priority for the group. For incoming calls destined to your PBX, DIDs are associated with an Endpoint Group to route the calls to your PBX. For outgoing calls from your PBX, a matching Endpoint Group is required to authorize outbound calls through the Skyetel network. Thus, the first step in configuring the Skyetel side for use with your PBX is to set up an Endpoint Group. Here’s a typical setup for Incredible PBX 16-15:

    • Name: MyPBX
    • Priority: 1
    • IP Address: PBX-Public-IP-Address
    • Port: 5060
    • Protocol: UDP
    • Description: 16-15.incrediblepbx.com

    To receive incoming PSTN calls, you’ll need at least one DID. On the Skyetel site, you acquire DIDs under the Phone Numbers tab. You have the option of Porting in Existing Numbers (free for the first 60 days after you fund your account) or purchasing new ones under the Buy Phone Numbers menu option.

    Once you have acquired one or more DIDs, navigate to the Local Numbers or Toll Free Numbers tab and specify the desired SIP Format and Endpoint Group for each DID. Add SMS/MMS and E911 support, if desired. Call Forwarding and Failover are also supported. That completes the VoIP setup on the Skyetel side. System Status is always available here.

    Configuring VoIP.ms for Incredible PBX 16-15

    To sign up for VoIP.ms service, may we suggest you use our signup link so that Nerd Vittles gets a referral credit for your signup. Once your account is set up, you’ll need to set up a SIP SubAccount and, for Authentication Type, choose Static IP Authentication and enter your Incredible PBX 16-15 server’s public IP address. For Transport, choose UDP. For Device Type, choose Asterisk, IP PBX, Gateway or VoIP Switch. Order a DID in their web panel, and then point the DID to the SubAccount you just created. Be sure to specify atlanta1.voip.ms as the POP from which to receive incoming calls.

    Configuring V1VoIP for Incredible PBX 16-15

    To sign up for V1VoIP service, sign up on their web site. Then login to your account and order a DID under the DIDs tab. Once the DID has been assigned, choose View DIDs and click on the Forwarding button beside your DID. For Option #1, choose Forward to IP Address/PBX. For the Fowarding Address, enter the public IP address of your server. For the T/O (timeout) value, set it to 2o seconds. Then click the Update button. Under the Termination tab, create a new Endpoint with the public IP address of your server so that you can place outbound calls through V1VoIP.

    Configuring Anveo Direct for Incredible PBX 16-15

    To sign up for Anveo Direct service, sign up on their web site and then login. After adding funds to your account, purchase a DID under Inbound Service -> Order DID. Next, choose Configure Destination SIP Trunk. Give the Trunk a name. For the Primary SIP URI, enter $[E164]$@server-IP-address. For Call Options, select your new DID from the list. You also must whitelist your public IP address under Outbound Service -> Configure. Create a new Call Termination Trunk and name it to match your server. For Dialing Prefix, choose six alphanumeric characters beginning with a zero. In Authorized IP Addresses, enter the public IP address of your server. Set an appropriate rate cap. We like $0.01 per minute to be safe. Set a concurrent calls limit. We like 2. For the Call Routing Method, choose Least Cost unless you’re feeling extravagant. For Routes/Carriers, choose Standard Routes. Write down your Dialing Prefix and then click the Save button.

    Before you can make outbound calls through Anveo Direct from your PBX, you first must configure the Dialing Prefix that you wrote down in the previous step. Using a browser, login to the GUI as admin. Navigate to Connectivity -> Trunks -> Anveo-Out. Click the Pencil icon to edit the trunk settings. Then click the Custom Settings tab. Replace anveo-pin with your actual Anveo PIN. Click Submit and Apply Settings to save your changes.

    By default, incoming Anveo Direct calls will be processed by the Default inbound route on your PBX. If you wish to redirect incoming Anveo Direct calls using DID-specific inbound routes, then you’ve got a bit more work to do. In addition to creating the inbound route using the 11-digit Anveo Direct DID, enter the following commands after logging into your server as root using SSH/Putty:

    cd /etc/asterisk
    echo "[from-anveo]" >> extensions_custom.conf
    echo "exten => _.,1,Ringing" >> extensions_custom.conf
    echo "exten => _.,n,Goto(from-trunk,\${SIP_HEADER(X-anveo-e164)},1)" >> extensions_custom.conf
    asterisk -rx "dialplan reload"
    

    Configuring a Softphone for Incredible PBX 16-15

    We’re in the home stretch now. You can connect virtually any kind of telephone to your new PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony.

    We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You can find them by running /root/show-passwords. You’ll need the IP address of your server plus your extension 701 password. In the YateClient, fill in the blanks using the IP address of your Server, 701 for your Username, and whatever Password was assigned to the extension when you installed Incredible PBX. Click OK to save your entries.

    blank

    Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

    DEMO - Apps Demo
    123 - Reminders
    947 - Weather by ZIP Code
    951 - Yahoo News
    TODAY - Today in History
    LENNY - The Telemarketer's Worst Nightmare
    

    If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store.

    Audio Issues with Incredible PBX 16-15

    Only if you experience one-way or no audio on some calls, add your external IP address and LAN subnet in the GUI by navigating to Settings -> Asterisk SIP Settings. In the NAT Settings section, click Detect Network Settings. Click Submit and Apply Settings to save your changes.

    Configuring Gmail as Exim Smart Relay Host

    Most Raspberry Pi implementations will be on networks managed by companies like Comcast, Spectrum, and AT&T that block downstream mail servers (that’s you) from sending email. The solution is to use Gmail or your local ISP as a smart relay host to send mail from your server. You’ll need this to deliver voicemails via email. Here’s how to set it up using a Gmail account without two-step authentication. Log into your server as root and run configure-exim-email. Choose "mail sent by smarthost; received via SMTP or fetchmail." Accept all the defaults until you get to Outgoing Smarthost prompt. Enter: smtp.gmail.com::587. At the following prompts, choose NO, NO, mbox, and NO. When the setup completes, edit /etc/exim4/passwd.client and insert the following line using your Gmail AcctName and AcctPW:

    *.google.com:AcctName@gmail.com:AcctPW
    smtp.gmail.com:AcctName@gmail.com:AcctPW
    

    Save the file and then issue the following commands to complete the setup:

    update-exim4.conf
    systemctl restart exim4
    exim4 -qff
    

    Now send yourself a test email message to make sure things are working properly:

    echo "test" | mail -s testmessage yourname@yourmailprovider.com
    

    Some prefer an email notification whenever your server is booted. Once you have configured a relay host above, you can add the feature by editing /etc/rc.local and adding the following lines with your actual email address just above the service knockd start line:

    _PRIVATE="Private IP: `cat /etc/hostip | cut -f1-2 -d " "`"
    _PUBLIC=" Public IP: `curl -s -S --user-agent \\
    "Mozilla/4.0" http://myip.incrediblepbx.com | awk 'NR==2'`"
    echo "$_PRIVATE\\n$_PUBLIC" | mail -s "RasPi 16-15 has booted" yourname@yourmailserver.com
    

    Incredible PBX 16-15 Administration

    We’ve eased the pain of administering your new PBX with a collection of scripts which you will find in the /root folder after logging in with SSH or Putty. Here’s a quick summary of what each of the scripts does.

    admin-pw-change lets you update the admin password for web browser access to the Incredible PBX GUI.

    apache-pw-change lets you update the admin password for Apache applications such as AsteriDex and Reminders.

    avantfax-pw-change lets you update the root password for AvantFax access (coming soon!).

    add-fqdn is used to whitelist a fully-qualified domain name in the firewall. Because Incredible PBX 16-15 blocks all traffic from IP addresses that are not whitelisted, this is what you use to authorize an external user for your PBX. The advantage of an FQDN is that you can use a dynamic DNS service to automatically update the IP address associated with an FQDN so that you never lose connectivity.

    add-ip is used to whitelist a public IP address in the firewall. See the add-fqdn explanation as to why this matters.

    del-acct is used to remove an IP address or FQDN from the firewall’s whitelist.

    configure-exim-email lets you reconfigure the email server if you need to use an SMTP relay such as Google to get outbound email flowing. Tutorial here.

    iptables-restart is the ONLY command you should ever use to restart the IPtables firewall and Fail2Ban.

    knock.FAQ contains your PortKnocker credentials for emergency access to your server if the firewall locks you out. Tutorial here.

    proximity (once configured) will automatically forward calls to your cellphone when you are out of BlueTooth range from your RasPi. Also must enable running of script in /etc/crontab.

    reset-conference-pins is a script that automatically and randomly resets the user and admin pins for access to the preconfigured conferencing application. Dial C-O-N-F from any registered SIP phone to connect to the conference.

    reset-extension-passwords is a script that automatically and randomly resets ALL of the SIP passwords for extensions 701-705. Be careful using this one, or you may disable existing registered phones and cause Fail2Ban to blacklist the IP addresses of those users. HINT: You can place a call to the Ring Group associated with all five extensions by dialing 777.

    reset-reminders-pin is a script that automatically and randomly resets the pin required to access the Telephone Reminders application by dialing 123. It’s important to protect this application because a nefarious user could set up a reminder to call a number anywhere in the world assuming your SIP provider’s account was configured to allow such calls.

    show-feature-codes is a cheat sheet for all of the feature codes which can be dialed from any registered SIP phone. It documents how powerful a platform Incredible PBX 16-15 actually is. A similar listing is available in the GUI at Admin -> Feature Codes.

    show-passwords is a script that displays ALL of the passwords associated with Incredible PBX 16-15. This includes SIP extension passwords, voicemail pins, conference pins, telephone reminders pin, and your Anveo Direct outbound calling pin (if configured). Note that voicemail pins are configured by the user of a SIP extension the first time the user accesses the voicemail system by dialing *97.

    timezone-setup lets you reconfigure the correct time zone for your server.

    purge-cdr-cel-records cleans out all existing entries in both the CDR and CEL tables of the Asterisk CDR database.

    log-cleanup removes all entries from most of the logs in /var/log.

    sig-fix disables module signature checking in FreePBX. It is automatically disabled upon installation.

    readme-RonR.txt documents the scripts provided from RonR build. We do NOT recommend using the FCC Blacklist because of its current size.

    update-IncrediblePBX is the Automatic Update Utility which checks for server updates from incrediblepbx.com every time you log into your server as root using SSH or Putty. Do NOT disable it as it is used to load important fixes and security updates when necessary. We recommend logging into your server at least once a week.

    pbxstatus (shown above) displays status of all major components of Incredible PBX 16-15.

    Forwarding Calls to Your Cellphone. Keep in mind that inbound calls to your DIDs automatically ring all five SIP extensions, 701-705. The easiest way to also ring your cellphone is to set one of these five extensions to forward incoming calls to your cellphone. After logging into your PBX as root, issue the following command to forward calls from extension 705 to your cellphone: asterisk -rx "database put CF 705 6781234567"

    To remove call forwarding: asterisk -rx "database del CF 705"

    Incredible PBX 16-15 Last-Minute Fixes

    For each release, we will post fixes for Incredible PBX 16-15 here. If you download a newer release, previous fixes have already been addressed and should not be applied. If you’re still using an earlier release, be sure to apply all patches for your release plus all patches for subsequent releases.

    Release 1 Fixes:

    Login to your server as root and issue the following commands to update your server. A reboot is not required unless noted.

    service knockd start
    sed -i 's|exit 0"|exit zero"|' /etc/rc.local
    sed -i 's|exit 0|service knockd start\\nexit 0|' /etc/rc.local
    /root/reset-extension-passwords
    

    A glitch in the admin-pw-change utility used to set the password for web access to the GUI has also been fixed. Simply log out of your server and log back in as root, and the Automatic Update Utility will fix the problem. You then can successfully set your admin password.

    Release 2 Fixes:

    # failed exim messages from Fail2Ban
    sed -i 's|/dev/null|:blackhole:|' /etc/aliases
    systemctl restart exim4
    exim -bp | exiqgrep -i | xargs exim -Mrm
    systemctl restart fail2ban
    # missing AGI files
    cd /var/lib/asterisk/agi-bin
    wget http://incrediblepbx.com/raspi1615-agibin.tar.gz
    tar zxvf raspi1615-agibin.tar.gz
    rm -f raspi1615-agibin.tar.gz
    

    Release 3 Updates/Fixes:

    Release 3 adds dozens of Incredible PBX applications. See the Application User’s Guide for tutorials. In addition, release 3 adds MySQL ODBC support (special thanks to @jerrm for sorting this out) with demo Asterisk applications for customer lookups (dial 222 and enter 12345) and AsteriDex speed dials (dial 223 and enter 335 (D-E-L) for Delta Airlines.

    Release 4 Updates/Fixes:

    Release 4 adds Allison’s Demo IVR and Stealth AutoAttendant as well as support for Blinkt!. It provides hourly alerts during the workday as well as whenever pbxstatus is run. You can order one here. This brings us to functional equivalence with the CentOS 7 release of Incredible PBX 16-15.

    Release 5 Updates/Fixes:

    Release 5 sets NAT default setting for all extensions to YES. This reduces the likelihood that callers will experience one-way audio on calls. The size of the swap file also was double to eliminate dashboard warning messages when some larger microSD cards were deployed.

    Migrating Painlessly from Incredible PBX 13-13 to 16-15

    blank

    Asterisk® 13 will be 6 years old this October. That’s like three lifetimes in VoIP years. So let’s face it. It’s time to start making plans to move on up. The latest LTS version is Asterisk 16 which gets you another 4+ years with security fixes. We won’t dwell on the shortcomings of PJsip in Asterisk 13 and the fact that chanSIP is getting long in the tooth. So the sooner you migrate the better off you will be. Thanks to the latest FreePBX® 15 Backup & Restore module and some great tips from @DavidFoxworth and @Kenn10 on the PIAF Forum, 16-15 migration should be painless. We’re a little late with this week’s article because we wanted to finish the script to also let you migrate your Call Detail Records as well. Now it’s soup.

    If you’re just getting started with Incredible PBX® 16-15 then you’ll get all of today’s additions as part of your initial install. Just follow our this tutorial. If you want to deploy Incredible PBX 16-15 as a public server on the Internet, this tutorial will walk you through that upgrade.

    Beginning the Incredible PBX 13-13 Migration

    For anyone that’s been involved with Asterisk and FreePBX, you already know what a pain it was to move from one release to another. It’s still not quite automatic, but it’s damn close. You can’t perform an in-place migration to move from Asterisk 13 and FreePBX 13 to Asteerisk 16 with FreePBX 15. So you’ll need to first bring up an Incredible PBX 16-15.1 platform that is separate and apart from your already functioning Incredible PBX 13-13.10 server. Once you’ve done that, use add-ip to whitelist the IP address of your 13-13 server on the 16-15 PBX and whitelist the IP address of your 16-15 server on the 13-13 PBX. This will make it easy to copy files between the two servers.

    In addition to the whitelisting procedure above, there are three more steps to complete on the Incredible PBX 13-13 server. First, you’ll need to update the backup module:

    cd /root
    ./gpl-install-fpbx backup
    

    Next, login to the GUI as admin using a browser and make a backup of your FreePBX components. Access Admin -> Backup & Restore and click Backup Wizard. Give the backup a name and description: incrediblepbx. Choose to run the backup Monthly. Choose Yes for voicemails, recordings, and CDR data. Choose Email Notifications and enter your email address. For Remote Save, choose No. Your backup will be saved locally in /var/spool/asterisk/backup/incrediblepbx. Click Finish.

    Click the Pencil icon under incrediblepbx Actions to edit the files to be backed up. Using the + icon, make your Items list look like the following:

    blank

    Click Save & Run button when you’ve made the necessary changes to kick off the backup. Unless you want monthly backups, you can click the trashcan icon under incrediblepbx Actions to remove the task we just created once the backup completes.

    Copy the backup file from /var/spool/asterisk/backup/incrediblepbx to your desktop PC.

    Finally, let’s back up your Call Detail Records (cdr/cel) which won’t get imported with the FreePBX 15 restore utility. Log in to the Linux CLI as root and issue the following commands to create the CDR backup and copy it to your 16-15 server. Replace the xx’s with the IP address of your 16-15 server.

    cd /root
    mysqldump -u root -ppassw0rd --single-transaction --quick \\ 
     --lock-tables=false asteriskcdrdb > asteriskcdr1313.sql
    gzip asteriskcdr1313.sql
    scp asteriskcdr1313.sql.gz root@xx.xx.xx.xx:/root/asteriskcdr1313.sql.gz
    

    Restoring Your Data to Incredible PBX 16-15

    Let’s begin on the Incredible PBX 16-15 server by logging into the Linux CLI as root. Issue the following commands to set up your server platform for the Incredible PBX 13-13 import. Unless you have just installed Incredible PBX 16-15 since 3 p.m. EDT today, be sure to perform all of the steps below. It won’t hurt to do it again just to be sure you have the latest and greatest code:

    cd /root
    wget http://incrediblepbx.com/newbackup16-15.tar.gz
    tar zxvf newbackup16-15.tar.gz
    rm -f newbackup16-15.tar.gz
    ./install-backup
    

    Next, login to the GUI as admin using your favorite browser. The new FreePBX 15 backup module is still a little rough around the edges, but it will get the job done. And that’s what matters. From the FreePBX Dashboard, choose Admin -> Backup & Restore. Be prepared. It will blow up. Not to worry. Click the Back button on your browser once or twice to return to the FreePBX Dashboard. Now repeat the drill: Admin -> Backup & Restore. This time it will work. Now click the Restore tab. Click on Upload a Backup File and choose the backup file from your desktop. Once the backup is loaded, click RunRestore button to begin. When the whirring stops, there will be an error message. Ignore it. Don’t click anything just yet. Instead, drop down to the Linux CLI again and run: /root/restore-fix.

    When it completes, return to the GUI and your browser, close the Restore dialog, and return to the Dashboard. Ignore the warning about Bind Ports. Click Settings->SIP Settings->SIP Settings (pj_sip) and scroll down to UDP. Click YES then Submit then Apply Config. We’re almost finished.

    Return to the Linux CLI and run: /root/import-cdr1313 to import your 13-13 cdr and cel data. This will overwrite existing CDR data on your 16-15 server. If anyone needs to get it back, we’ll add the steps below in coming days. Stay tuned.

    Known Issues with Incredible PBX 13-13 Imports

    You now can use your browser to review your setup and verify that your 13-13 data came over. If you’re using CallerID Superfecta, you’ll need to enable it under Admin -> CID Superfecta. Next, access Applications -> Misc Applications and set the extension for Demo IVR to 3366. Save your settings and reload the dialplan when prompted. Be advised that Custom Destinations currently do not populate so you’ll need to cut-and-paste your entries from your 13-13 server. There should only be a few: Fax (HylaFax), Time of Day, and perhaps OutAnyWhere. OSS EndPoint Manager is not compatible with FreePBX 15 and will not be restored. Finally, verify that voicemail settings for your extensions got properly set. You may need to again enable voicemail, set a VM password, and configure email delivery of voicemails, if desired.

    FIXED: Importing Ring Groups from 13-13 caused calls to fail unless Send Progress was set to No for each of the ring groups. This is no longer necessary. Voicemail data did not get restored properly. This has been fixed by running restore-fix script.

    Managing CDR Data with Incredible PBX 16-15

    Call Detail Records are stored in two tables in MySQL’s asteriskcdrdb database. Unlike in FreePBX 13, FreePBX 15 uses the InnoDB storage engine and a number of new fields in the cdr table so don’t attempt to merely restore your FreePBX 13 asteriskcdrdb database to FreePBX 15, or you will get a royal mess. Our conversion utility, import-cdr1313, makes it easy to migrate the data as explained above. What we didn’t do was restore any existing CDR data you may have already accumulated on your 16-15 server. But we did make a backup of the data which is stored in asteriskcdr1615new.sql. You can use this backup for two purposes. You can replace the CDR 13-13 data that we just imported with your original 16-15 data, or you can add your previous CDR 16-15 data to the 13-13 data. As stored, asteriskcdr1615new.sql will completely replace the existing contents of the asteriskcdrdb database using the command:

    mysql -u root -ppassw0rd asteriskcdrdb < asteriskcdr1615new.sql
    

    If you want to supplement the 13-13 CDR data that was imported with your previous 16-15 CDR data, it's a bit more complex. Begin by making a couple copies of the backup file and then we'll edit one of the new files:

    cp asteriskcdr1615new.sql asteriskcdr1615bak.sql
    cp asteriskcdr1615new.sql asteriskcdr1615supp.sql
    nano -w asteriskcdr1615supp.sql
    

    We need to delete two sections from the file. First, scroll down to Table structure for table `cdr`. Press Ctrl-K to cut (delete) every line until you reach Dumping data for table `cdr`. Second, scroll down further to Table structure for table `cel`. Press Ctrl-K to cut (delete) every line until you reach Dumping data for table `cel`. Now Save the modified file: Ctrl-X, Y, then ENTER. You now can append your previous 16-15 CDR data to the current CDR database with the following command:

    mysql -u root -ppassw0rd asteriskcdrdb < asteriskcdr1615supp.sql
    

    We're all human and sometimes mistakes are made. Not to worry. You can put Humpty back together again by starting with your original CDR database, adding the 13-13 CDR data again, and then supplementing it with your previous 16-15 data. Here's how.

    mysql -u root -ppassw0rd asteriskcdrdb < asteriskcdr1615bak.sql
    ./import-cdr1313
    cp asteriskcdr1615new.sql asteriskcdr1615supp.sql
    # make required changes described above to asteriskcdr1615supp.sql
    mysql -u root -ppassw0rd asteriskcdrdb < asteriskcdr1615supp.sql
    

    Two other tips, and you'll be a CDR database expert. First, you can restore an empty (but functional) CDR database with this command:

    mysql -u root -ppassw0rd asteriskcdrdb < asteriskcdrdb.sql
    

    Finally, you can make a backup of your existing CDR database at any time with the command:

    mysqldump -u root -ppassw0rd --single-transaction --quick \\
     --lock-tables=false asteriskcdrdb > asteriskcdr1615latest.sql

    Deploying an Incredible PBX 16-15 Public Server with Skyetel

    blank

    Safely deploying a public-facing Asterisk® server with full FreePBX® functionality has become the Holy Grail for Nerd Vittles in 2019. Today we tackle it on our new Incredible PBX® 16-15 platform featuring the latest releases of Asterisk 16 and FreePBX 15. The icing on today’s cake is a terrific new offer from Skyetel that supplements the current Nerd Vittles BOGO offer of up to $500 in half-priced VoIP services. Beginning today, Skyetel also will start you off with a $10 credit just for opening an account here. Then, after you have had an opportunity to kick the tires and perhaps purchase a DID for a buck, you can make $9 worth of phone calls before deciding whether to take advantage of the BOGO special by making a purchase of up to $250 and having Skyetel match your contribution. Once you have funded your account, you then can also take advantage of Skyetel’s free number porting offer for the next 60 days. To get your $10 credit, just open a ticket and request the $10 Nerd Vittles credit once you’ve signed up. To get the Nerd Vittles BOGO price match and take advantage of free number porting, simply open another ticket once you have added up to $250 to your account. Effective 10/1/2023, $25/month minimum spend required.

    Making the Case for a Public-Facing PBX

    We’ve had some of our pioneers trying out the new Incredible PBX 16-15-PUBLIC implementation this past week, and the question arose as to why anyone would want to do this. After all, PBX in a Flash 3 and Incredible PBX for the better part of a decade have been deployed with a whitelist using the Travelin’ Man 3 firewall, and there’s never been a security issue. So why switch horses now? The short answer is mobile users with dynamic IP addresses. If all the users of your PBX are sitting behind the same NAT-based router with static IP addresses, the Travelin’ Man 3 design is perfect. The bad guys could never even see your server. But if some of your users either reside or travel outside your home base or if you want calls to follow you on your smartphone when you leave home or the office, then Travelin’ Man 3 blocked SIP access from these remote phones until their new IP addresses were whitelisted. Multiply this by dozens or hundreds of users, and network management suddenly became a full-time job. Yes, we’ve had tools such as dynamic DNS and PortKnocker to ease the pain, but it still was a knuckle-drill for mobile users. And, in today’s world, much of the workforce is quickly morphing into mobile users without a traditional desk at an office.

    The world also is becoming more SIP savvy. Just as folks are learning that a $35 antenna can provide an awesome collection of 4K Ultra HD TV channels without the expense of a monthly cable bill, others are learning that a SIP telephone or softphone app on your smartphone can provide free calls to and from anybody with a SIP URI without sharing your communications with Facebook or Microsoft. Today’s PUBLIC PBX makes free worldwide SIP calling a reality.

    Building the Base Platform for Incredible PBX PUBLIC

    To get started today, you need to begin by installing Incredible PBX 16-15 using the latest tutorial. There still are a few bugs in the FreePBX 15 fax module so you won’t be able to successfully install and use Incredible Fax for the time being. We’ll let everyone know when the issues have been resolved.

    Once you have set up your Incredible PBX 16-15.2 server, the next step is to assign one or two fully-qualified domain names (FQDNs) to your server. You can have one FQDN for registering SIP extensions and a different one for anonymous SIP (invites) access to your server, or you can use the same FQDN for both. Security through obscurity provides an extra layer of protection for your server so choose your FQDNs carefully. sip.yourname.com provides almost no protection while f246g.yourname.com pretty much assures that nobody is going to guess your domain name. This is particularly important with the FQDN for SIP registrations because registered extensions on your PBX can obviously make phone calls that cost money.

    By default, Incredible PBX 16-15 configures five extensions (701-705) and a Ring Group for those extensions (777) as well as four trunks including Skyetel. It’s ready to make and receive calls as soon as you sign up with one of the four providers listed in the tutorial. You can add as many additional providers and extensions as you like and modify the ring group to meet your needs. To get started, be sure to configure the correct time zone for your server as this affects delivery of reminders. Run /root/timezone-setup. Next, set a secure password for admin access to the FreePBX GUI modules. Run /root/admin-pw-change. Then set a secure password for admin access to web applications such as AsteriDex, Reminders, and User Control Panel. Run /root/apache-pw-change. In addition to reviewing your extensions and ring group, review the default inbound route and choose the destination for the incoming calls from your provider. Finally, configure the outbound route to use the provider sequence desired. By default, it uses Skyetel for outbound calls.

    Going Public with Incredible PBX 16-15

    Once you’ve tested making and receiving calls with your new server, you’re ready to convert it into a public-facing PBX. In order to run the install script below, you’ll need your FQDNs that you chose above, plus a port number for future SSH/Putty access to your server, plus a list of the extensions you wish to make available for public access to your PBX. These whitelisted extensions can be reached via SIP URI from anywhere in the world by anybody. It works just like your old MaBell phone. Anybody, anywhere can dial your number. What’s changed is now the calls are free. So choose your list carefully. We recommend using the year you were born for your SSH port to keep things simple for you. Once the GO-PUBLIC-16-15 script has been run, you can only access your PBX via SSH/Putty at the new port, e.g. SSH -p 1990 root@yourFQDN.com

    Now we’re ready to run the install script. It takes less than a minute. Before you begin, log out of ALL SIP extensions you have previously registered with Incredible PBX and change the server destination from an IP address to the FQDN you plan to assign to SIP registrations. Otherwise, these IP addresses will get banned while the install script is running below!

    cd /root
    wget http://incrediblepbx.com/go-public-16-15.tar.gz
    tar zxvf go-public-16-15.tar.gz
    rm -f go-public-16-15.tar.gz
    ./GO-PUBLIC-16-15
    

    A Few Words About Incredible PBX PUBLIC Security

    As with all Incredible PBX servers, Incredible PBX 16-15-PUBLIC includes the Automatic Update Utility. Please don’t disable it. It’s our only way to push updates to you if some vulnerability is discovered down the road. It gets run whenever you login to your server as root using SSH/Putty. Do so regularly and follow us on Twitter for security alerts. There’s also an Incredible PBX RSS Feed that is displayed when you login to the Incredible PBX GUI with a browser. It, too, includes security alerts and should be checked regularly. It’s your phone bill.

    Incredible PBX 16-15-PUBLIC uses the ipset utility in conjunction with the IPtables firewall to block several countries that have inordinately high concentrations of folks that try to break into VoIP servers. In addition, your public PBX includes the VoIP Blacklist which includes another 100,000 bad guys from around the globe. These blacklists get updated every night by a script which is run from /etc/crontab. For your own safety, don’t disable or delete /etc/update-voipbl.sh or the other components upon which it relies.

    Here are some other things you should do regularly to assure that your server remains secure. Login via SSH/Putty as root and check pbxstatus after the Automatic Update Utility is run. With the exception of the fax components, all the other items should be green all the time. From the Linux CLI, run: iptables -nL. This will show your firewall rules and whether any IP addresses have been banned by Fail2Ban. If there are banned IP addresses that are not your own, please open a thread on the PIAF Forum and let us know about it. If there are dozens of banned IP addresses, shutdown your server immediately until the problem is identified and resolved. If the IP addresses happen to be your own users because of using incorrect passwords or because of using a server IP address instead of its FQDN for SIP registrations, unban the IP address: fail2ban-client set asterisk unbanip xxx.xxx.xxx.xxx
    Finally, watch the Asterisk CLI periodically for abnormal activity: asterisk -rvvvvvvvvvv

    Tightening Up SSH Server Access

    You obviously need a very secure root password for access to your server using SSH/Putty. Changing the TCP port for SSH access avoids the script kiddies, but it doesn’t offer much protection from a determined cracker. SSH login attempts are monitored by Fail2Ban, but Fail2Ban has issues when a determined intruder is using a powerful computing platform such as Amazon EC2. The more prudent solution is to disable SSH port access and use SSH Public Key Authentication as documented in the linked tutorial. Always, always use ssh-copy-id to copy your credentials to more than one desktop machine so that you don’t inadvertently lock yourself out of your PBX in the case of a hardware failure.

    Introducing the VitalPBX Communicator

    Our previous article offered some suggestions for SIP softphones. These become more important once you deploy a public-facing PBX and want to stay connected while you’re away from home or the office. If you’re using an Android smartphone even without a SIM card and provider, there is no finer softphone than the new VitalPBX Communicator. Using the Account Assistant, enter the SIP extension of your PBX as the Username. Enter the SIP extension password as the Password. For the Domain, enter the SIP registration FQDN you specified above (not the IP address of your server!). Choose UDP for the Transport. And click Login to begin. In the Network Settings, turn OFF WiFi only. If you enable Background Mode and Start At Boot Time in Advanced Settings, the softphone will remain registered and available even when you’re using other applications. On a Google Pixel 3, this consumes about 20% of the phone’s battery life from a full charge. A similar app is available for Windows-based PCs. An iPhone app is under development.

    For other platforms, the Linphone application is an excellent alternative. See our previous Linphone tutorial for details. Here are the download links for each supported platform:

    A Word to the Wise. Our experience suggests that SIP communications with an iPhone is notoriously awful. Under identical conditions using the same application on both an iPhone and an Android phone typically results in calls failing or experiencing one-way or no audio on the iPhone. Save yourself some frustration and purchase ANY Android phone for SIP communications (HINT: With the exception of the camera, the Moto g6 is virtually identical in shape and performance to Google’s Pixel 3 at less than one-third the cost). As noted, no SIM card is required. WiFi works perfectly. If you want a cell phone provider, check out Mint Mobile’s dirt cheap offering ($15/mo. for unlimited calls and text plus 3GB of LTE data). Nerd Vittles (and you) receive a perk when you use our link to sign up for service.

    Special Thanks: We want to give an extra special tip of the hat to the PIAF Forum members who assisted in working the kinks out of the last two weeks’ Incredible PBX 16-15 offerings. We also wish to thank JavaPipe LLC for a number of DDOS tips and tricks in securing CentOS 7 with IPtables.

    Enchilada Amore: It’s Incredible PBX 16-15 for CentOS 7

    blank

    Just when you thought the VoIP community was running out of open source offerings, along comes last week’s Incredible PBX 16® LITE and today’s Incredible PBX 16-15 for CentOS® 7 featuring the same great feature set as the LITE version including Asterisk 16®. And now you also get the entire FreePBX® 15 GPL module collection including their new User Control Panel (UCP) and a much enhanced web GUI plus the entire Incredible PBX feature set. As with Incredible PBX LITE, it’s plug-and-play with immediate calling capability using any of four commercial SIP providers. Or you can choose one of 16 other preconfigured SIP providers, enter your credentials, and enjoy instant connectivity without worrying about SIP settings. We began the Incredible PBX 16 adventure last week. Let’s catch you up if you’re just joining.

    UPDATE: A new release of Incredible PBX 16-15 is now available here. It resolves most issues with migration from Incredible PBX 13-13.

    UPDATE: Turn your Incredible PBX 16-15 server into a secure public-facing PBX. Here’s how.

    What’s Included? Incredible PBX 16-15 serves up a VoIP powerhouse featuring Asterisk 16, the FreePBX 15 GPL platform including User Control Panel (UCP), an Apache web server, the latest MariaDB SQL server (formerly MySQL), SendMail, and the Incredible PBX feature set including SIP, SMS, Opus, voice recognition, PicoTTS Text-to-Speech VoIP applications plus fax support, Click-to-Dial, News, Weather, Reminders, ODBC, and hundreds of features that typically are found in commercial PBXs: Conferencing, IVRs and AutoAttendants, Email Delivery of Voicemail, and much more.

    Choosing a SIP Provider. Incredible PBX 16-15 comes preconfigured with support for five SIP extensions and four of the major SIP providers: Skyetel, VoIP.ms, V1VoIP, and Anveo Direct. We obviously hope you’ll choose Skyetel not only because they financially support Nerd Vittles and our open source projects, but also because it is a clearly superior platform offering crystal-clear communications and triple-redundancy so you never miss a call. Skyetel also sets itself apart from the other providers in the support department. They actually respond to issues, and there’s never a charge. As the old saying goes, they may not be the cheapest, but you get what you pay for. Even without taking advantage of Nerd Vittles half-price offer on up to $500 of Skyetel services, they’re still dirt cheap compared to the Bell Sisters and cable companies. Traditional DIDs are $1 per month. Outbound conversational calls are $0.012 per minute. Incoming conversational calls are a penny a minute, and CallerID lookups are $0.004. With all four providers, you only pay for minutes you use. Using more than one is a good idea.

    Choosing a Platform for Incredible PBX 16-15

    As with our other open source offerings, the platform choice for Incredible PBX 16-15 depends upon a number of factors. For most folks, you’d be crazy to go out and purchase hardware to use in your home or office when cloud-based platforms are available for about a dollar a month. Unless you plan to publicly expose your server on the Internet to facilitate remote SIP connections, the OpenVZ offerings below are perfectly adequate while in business with the cautionary note that you need off-site backups AND a tested backup plan. Three providers previously listed have closed their doors in 2019. You’ve been warned.

    Installing Incredible PBX 16-15 with CentOS 7

    If you’ve installed previous iterations of Incredible PBX, today’s drill is similar. Here is a thumbnail sketch of the install procedure for Incredible PBX 16-15. Begin by installing a minimal CentOS 7 (64-bit) platform or pick the CentOS 7 option with 1GB RAM and 20GB of storage from your cloud provider’s menu of choices. Then log into your server as root and issue the following commands:

    passwd
    yum -y update
    yum -y install net-tools nano wget tar
    wget http://incrediblepbx.com/incrediblepbx16-15.1.tar.gz
    tar zxvf incrediblepbx16-15.1.tar.gz
    rm -f incrediblepbx16-15.1.tar.gz
    # to add swap file on non-OpenVZ cloud platforms with no swap file
    ./create-swapfile-DO
    # kick off Phase I install
    ./IncrediblePBX16-15.sh
    # after reboot, kick off Phase II install
    ./IncrediblePBX16-15.sh
    # add HylaFax/AvantFax, if desired
    ./incrediblefax16.sh
    # set desired timezone
    ./timezone-setup
    # display your passwords
    ./show-passwords
    # remember to enable TUN/TAP if using VPS Control Panel with OpenVZ
    # reconfigure PortKnocker if installing on an OpenVZ platform
    echo 'OPTIONS="-i venet0:0"' >> /etc/sysconfig/knockd
    service knockd restart
    # set up NeoRouter VPN client, if desired
    nrclientcmd
    # check network speed
    wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
    chmod +x speedtest-cli
    ./speedtest-cli
    

    WebMin is also installed and configured as part of the base install. The root password for access is the same as your Linux root password. We strongly recommend that you not use WebMin to make configuration changes to your server. You may inadvertently damage the operation of your PBX beyond repair. WebMin is an excellent tool to LOOK at how your server is configured. When used for that purpose, we highly recommend WebMin as a way to become familiar with your Linux configuration.

    Planning Ahead for That Rainy Day

    If you haven’t already learned the hard way, let us save you from a future shock. Hardware fails. All of it. So spend an extra hour now so that you’ll be prepared when (not if) disaster strikes. First, once you have your new PBX configured the way you plan to use it, make a backup of your PBX by running the Incredible Backup script: /root/incrediblebackup16

    Copy down the name of the backup file that was created. You’ll need it in a few minutes.

    Second, build yourself an identical VirtualBox platform on your desktop PC. It’s the same steps as outlined above.

    Next, create a /backup folder on your VirtualBox PBX and copy the backup file from your main server to your VirtualBox server and restore it after logging in to VirtualBox PBX as root:

    mkdir /backup
    scp root@main-pbx-ip-address:/backup/backup-file-name.tar.gz /backup/.
    /root/incrediblerestore16 /backup/backup-file-name.tar.gz
    

    Complaints that you "forgot" to make a backup and your hardware has failed or your provider has gone out of business are not welcomed. We’re sorry for your loss. Case closed.

    Completing the Incredible PBX Setup Procedure

    Unless your desktop PC and server are both on the same private LAN, the install procedure should be performed from a desktop PC using SSH or Putty. This will insure that your desktop PC is also whitelisted in the Incredible PBX firewall. Using the console to perform the install is NOT recommended as your desktop PC will not be whitelisted in the firewall. This may result in your not being able to log in to your server. Once you have network connectivity, log in to your server as root from a desktop PC using your root password. Accept the license agreement by pressing ENTER.

    Kick off the Phase I install. Once your server reboots and you log back in as root, start the Phase II install. All of your passwords will be randomly assigned with the exception of the root user Linux password. You can set it at any time by issuing the command: passwd. With the exception of your root user password, the remaining passwords can be displayed using the command: /root/show-passwords.

    Finally, if your PBX is sitting behind a NAT-based router, you’ll need to redirect incoming UDP 5060 and UDP 10000-20000 traffic to the private IP address of your PBX. This is required for all of the SIP providers included in the Incredible PBX 16-15 default build. Otherwise, inbound calls will fail.

    blank

    Configuring Skyetel for Incredible PBX 16-15

    If you’ve decided to go with Skyetel, here’s the drill. Sign up for Skyetel service and take advantage of the Nerd Vittles BOGO special. First, complete the Prequalification Form here. You then will be provided a link to the Skyetel site to complete your registration. Once you have registered on the Skyetel site and your account has been activated, open a support ticket and request the BOGO credit for your account by referencing the Nerd Vittles special offer. Skyetel will match your deposit of up to $250 which gets you up to $500 of helf-price calling. Credit is limited to one per person/company/address/location. Effective 10/1/2023, $25/month minimum spend required.

    Skyetel does not use SIP registrations to make connections to your PBX. Instead, Skyetel utilizes Endpoint Groups to identify which servers can communicate with the Skyetel service. An Endpoint Group consists of a Name, an IP address, a UDP or TCP port for the connection, and a numerical Priority for the group. For incoming calls destined to your PBX, DIDs are associated with an Endpoint Group to route the calls to your PBX. For outgoing calls from your PBX, a matching Endpoint Group is required to authorize outbound calls through the Skyetel network. Thus, the first step in configuring the Skyetel side for use with your PBX is to set up an Endpoint Group. Here’s a typical setup for Incredible PBX 16-15:

    • Name: MyPBX
    • Priority: 1
    • IP Address: PBX-Public-IP-Address
    • Port: 5060
    • Protocol: UDP

    To receive incoming PSTN calls, you’ll need at least one DID. On the Skyetel site, you acquire DIDs under the Phone Numbers tab. You have the option of Porting in Existing Numbers (free for the first 60 days after you sign up for service) or purchasing new ones under the Buy Phone Numbers menu option.

    Once you have acquired one or more DIDs, navigate to the Local Numbers or Toll Free Numbers tab and specify the desired SIP Format and Endpoint Group for each DID. Add SMS/MMS and E911 support, if desired. Call Forwarding and Failover are also supported. That completes the VoIP setup on the Skyetel side. System Status is always available here.

    Configuring VoIP.ms for Incredible PBX 16-15

    To sign up for VoIP.ms service, may we suggest you use our signup link so that Nerd Vittles gets a referral credit for your signup. Once your account is set up, you’ll need to set up a SIP SubAccount and, for Authentication Type, choose Static IP Authentication and enter your Incredible PBX 16-15 server’s public IP address. For Transport, choose UDP. For Device Type, choose Asterisk, IP PBX, Gateway or VoIP Switch. Order a DID in their web panel, and then point the DID to the SubAccount you just created. Be sure to specify atlanta1.voip.ms as the POP from which to receive incoming calls.

    Configuring V1VoIP for Incredible PBX 16-15

    To sign up for V1VoIP service, sign up on their web site. Then login to your account and order a DID under the DIDs tab. Once the DID has been assigned, choose View DIDs and click on the Forwarding button beside your DID. For Option #1, choose Forward to IP Address/PBX. For the Forwarding Address, enter the public IP address of your server. For the T/O (timeout) value, set it to 2o seconds. Then click the Update button. Under the Termination tab, create a new Endpoint with the public IP address of your server so that you can place outbound calls through V1VoIP.

    Configuring Anveo Direct for Incredible PBX 16-15

    To sign up for Anveo Direct service, sign up on their web site and then login. After adding funds to your account, purchase a DID under Inbound Service -> Order DID. Next, choose Configure Destination SIP Trunk. Give the Trunk a name. For the Primary SIP URI, enter $[E164]$@server-IP-address. For Call Options, select your new DID from the list. You also must whitelist your public IP address under Outbound Service -> Configure. Create a new Call Termination Trunk and name it to match your server. For Dialing Prefix, choose six alphanumeric characters beginning with a zero. In Authorized IP Addresses, enter the public IP address of your server. Set an appropriate rate cap. We like $0.01 per minute to be safe. Set a concurrent calls limit. We like 2. For the Call Routing Method, choose Least Cost unless you’re feeling extravagant. For Routes/Carriers, choose Standard Routes. Write down your Dialing Prefix and then click the Save button.

    Before you can make outbound calls through Anveo Direct from your PBX, you first must configure the Dialing Prefix that you wrote down in the previous step. Log into the GUI as admin using a web browser and edit the Anveo-Out trunk in Connectivity -> Trunks. Click on the custom-Settings tab and replace anveo-pin with your actual Dialing Prefix. Click Submit and Apply Config to complete the setup.

    By default, incoming Anveo Direct calls will be processed by the Default inbound route on your PBX. If you wish to redirect incoming Anveo Direct calls using DID-specific inbound routes, then you’ve got a bit more work to do. In addition to creating the inbound route using the 11-digit Anveo Direct DID, enter the following commands after logging into your server as root using SSH/Putty:

    cd /etc/asterisk
    echo "[from-anveo]" >> extensions_custom.conf
    echo "exten => _.,1,Ringing" >> extensions_custom.conf
    echo "exten => _.,n,Goto(from-trunk,\${SIP_HEADER(X-anveo-e164)},1)" >> extensions_custom.conf
    asterisk -rx "dialplan reload"
    

    Configuring a Softphone for Incredible PBX 16-15

    We’re in the home stretch now. You can connect virtually any kind of telephone to your new PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony.

    We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You can find them by running /root/show-passwords. You’ll need the IP address of your server plus your extension 701 password. In the YateClient, fill in the blanks using the IP address of your Server, 701 for your Username, and whatever Password was assigned to the extension when you installed Incredible PBX. Click OK to save your entries.

    blank

    Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

    DEMO - Apps Demo
    123 - Reminders
    947 - Weather by ZIP Code
    951 - Yahoo News
    TODAY - Today in History
    LENNY - The Telemarketer's Worst Nightmare
    

    If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store. For Android users, check out the terrific new VitalPBX Communicator. Works flawlessly with Incredible PBX.

    Audio Issues with Incredible PBX 16-15

    Only if you experience one-way or no audio on some calls, add your external IP address and LAN subnet in the GUI by navigating to Settings -> Asterisk SIP Settings. In the NAT Settings section, click Detect Network Settings. Click Submit and Apply Settings to save your changes.

    Incredible PBX 16-15 Administration

    We’ve eased the pain of administering your new PBX with a collection of scripts which you will find in the /root folder after logging in with SSH or Putty. Here’s a quick summary of what each of the scripts does.

    add-fqdn is used to whitelist a fully-qualified domain name in the firewall. Because Incredible PBX 16-15 blocks all traffic from IP addresses that are not whitelisted, this is what you use to authorize an external user for your PBX. The advantage of an FQDN is that you can use a dynamic DNS service to automatically update the IP address associated with an FQDN so that you never lose connectivity.

    add-ip is used to whitelist a public IP address in the firewall. See the add-fqdn explanation as to why this matters.

    del-acct is used to remove an IP address or FQDN from the firewall’s whitelist.

    reset-conference-pins is a script that automatically and randomly resets the user and admin pins for access to the preconfigured conferencing application. Dial C-O-N-F from any registered SIP phone to connect to the conference.

    reset-extension-passwords is a script that automatically and randomly resets ALL of the SIP passwords for extensions 701-705. Be careful using this one, or you may disable existing registered phones and cause Fail2Ban to blacklist the IP addresses of those users. HINT: You can place a call to the Ring Group associated with all five extensions by dialing 777.

    reset-reminders-pin is a script that automatically and randomly resets the pin required to access the Telephone Reminders application by dialing 123. It’s important to protect this application because a nefarious user could set up a reminder to call a number anywhere in the world assuming your SIP provider’s account was configured to allow such calls.

    show-feature-codes is a cheat sheet for all of the feature codes which can be dialed from any registered SIP phone. It documents how powerful a platform Incredible PBX 16-15 actually is. A similar listing is available in the GUI at Admin -> Feature Codes.

    show-passwords is a script that displays ALL of the passwords associated with Incredible PBX 16-15. This includes SIP extension passwords, voicemail pins, conference pins, telephone reminders pin, and your Anveo Direct outbound calling pin (if configured). Note that voicemail pins are configured by the user of a SIP extension the first time the user accesses the voicemail system by dialing *97.

    update-IncrediblePBX is the Automatic Update Utility which checks for server updates from incrediblepbx.com every time you log into your server as root using SSH or Putty. Do NOT disable it as it is used to load important fixes and security updates when necessary. We recommend logging into your server at least once a week.

    pbxstatus (shown above) displays status of all major components of Incredible PBX 16-15.

    Forwarding Calls to Your Cellphone. Keep in mind that inbound calls to your DIDs automatically ring all five SIP extensions, 701-705. The easiest way to also ring your cellphone is to set one of these five extensions to forward incoming calls to your cellphone. After logging into your PBX as root, issue the following command to forward calls from extension 705 to your cellphone: asterisk -rx "database put CF 705 6781234567"

    To remove call forwarding: asterisk -rx "database del CF 705"

    Configuring SendMail with Incredible PBX 16-15

    In order to receive voicemails by email delivery, outbound mail functionality from your server obviously is required. If you’ve deployed your server in your home, your Internet Service Provider probably blocks downstream mail servers such as Incredible PBX from sending mail. This is done to reduce SPAM. In this case, you will need to configure SendMail using either your ISP or Gmail as an SMTP Relay Host. Here are the steps using a Gmail account:

    cd /etc/mail
    yum -y install sendmail-cf
    hostname -f > genericsdomain
    touch genericstable
    makemap -r hash genericstable.db < genericstable
    mv sendmail.mc sendmail.mc.original
    wget http://incrediblepbx.com/sendmail.mc.gmail
    cp sendmail.mc.gmail sendmail.mc
    mkdir -p auth
    chmod 700 auth
    cd auth
    echo AuthInfo:smtp.gmail.com \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" > client-info
    echo AuthInfo:smtp.gmail.com:587 \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" >> client-info
    echo AuthInfo:smtp.gmail.com:465 \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" >> client-info
    # Stop here and edit client-info (nano -w client-info) in all three lines.
    # Replace  user_id with your gMail account name without @gmail.com
    # Replace password with your real gMail password
    # Be sure to replace the double-quotes shown above if they don't appear in the file!!!
    # Save your changes (Ctrl-X, Y, then Enter)
    chmod 600 client-info
    makemap -r hash client-info.db < client-info
    cd ..
    make
    systemctl restart sendmail
    

    If your server is hosted in the cloud and your provider does not block TCP port 25, then you can send mail without using a SmartHost; however, your server's hostname must actually be real or downstream mail servers will reject your mail. You can set your server's hostname like this: hostname myserver.myhost.com. This is usually sufficient; however, it's a good idea to also add the hostname in /etc/hostname and in /etc/hosts as the first entry on 127.0.0.1 line:

    127.0.0.1   myserver.myhost.com pbx.local localhost localhost.localdomain
    

    Next, test outbound mail using this command with your actual email address:

    echo "test" | mail -s testmessage yourname@youremaildomain.com
    

    Once you are sure your emails are being delivered reliably, here's a sample GUI voicemail configuration for an extension:

    Getting Started with Incredible Fax 16

    Believe it or not, there still are lots of folks that use faxes in their everyday lives. If you're one of them, Incredible PBX has your back. Begin by logging into your server as root and running incrediblefax16.sh to install HylaFax and AvantFax on your server. You'll be prompted a dozen or more times for information. Answer no to the secure fax question. For the rest of the prompts, just press ENTER to accept the default entries. Rebooting your server is required when the install finishes. Once your server is back on line, there will be a new AvantFax tab in the GUI. Before proceeding, be sure to set an Apache web apps password by running /root/apache-pw-change. Next, login to AvantFax with your browser. You first will be prompted for your Apache credentials. Enter admin for the username and whatever password you set up in the previous step. Then you will be prompted for your AvantFax credentials. The default is admin:password. After you enter the username and password, you will be prompted to change your admin password. The old password is still password. Then enter your desired password twice and save the setting. The AvantFax dashboard then will display. If nothing has come unglued, you should see four green Idle icons:


    blank

    You can Send Faxes from within AvantFax by choosing the Send Fax tab, or you can use one of many HylaFax clients. Google is your friend.

    Receiving faxes currently has issues not the least of which are fax detection being broken and incoming faxes never reaching the specified destination. We will continue to work on this and provide updates when they become available. For the time being, the simple workaround if you're using Skyetel as your provider is to designate a DID as a fax line (Call Routing: vFax) in the Skyetel Dashboard. Then Skyetel will manage the incoming faxes without any additional configuration on your PBX. You still can send faxes from within the AvantFax GUI.

    Getting Started with ODBC for Asterisk

    If you're new to the ODBC World, here's a quick primer. The idea behind Open Data Base Connectivity is to simplify the task of connecting up any flavor database management system so that it can talk to applications and foreign databases without having to write custom code to support every different DBMS. ODBC serves in much the same way as a translator who sits between you and foreign visitors. With the benefit of a translator, whatever is spoken is understood on both ends of the conversation. The real beauty of ODBC is that it is conversant with almost every DBMS offering on the planet including Oracle, Informix, SAS, MS Access, DB2, SQL Server, MySQL, MariaDB, PostgreSQL, Sybase, and even dBase, FoxPro, and XDB. All you really need is the ODBC connector for your operating system plus one or more database drivers for the DBMS data sources you wish to use.

    Because the FreePBX modules are driven by MySQL tables, we've included the MySQL connector for Asterisk in Incredible PBX 16-15 together with two sample applications to get you started. If you add your own MySQL databases, it's easy to connect them with ODBC by simply running the odbc-gen.sh script in /root again. The two sample applications we've included will show you how to integrate ODBC queries into your Asterisk dialplan. The code is available in odbc.conf in the /etc/asterisk folder. The first sample is a typical employee database. By dialing 222, you will be prompted to enter the employee number (12345), and the ODBC app then will look up the employee number and read you the name of the employee. The second sample is a speed dialer using the AsteriDex database. The sample entries in the database include a 3-numeric-digit DIALCODE which simply matches the first three letters of each AsteriDex name spelled out on a phone, e.g. 335 = DELta Airlines and 263 = AMErican Airlines. As you add new entries to AsteriDex, you can add dialcodes in the same way or in any other scheme you prefer. Once you have signed up with a provider so that you can make outbound calls, just dial 223 and enter the AsteriDex dialcode to place the call. Think of it as a Speed Dialer on Steroids.

    Introducing Incredible PBX 16 LITE for CentOS 7

    blank

    We had a banner week with the introduction of Incredible PBX® LITE for Raspbian 10. What we heard privately from many users was that they’d always wanted a turnkey PBX that was preconfigured to make and receive calls. The irony of offering this platform without the FreePBX® GUI to celebrate Independence Day was not lost on many of our savvy supporters. And, while the bells and whistles were icing on the cake, many simply wanted a flexible VoIP platform that didn’t require going back to college. This week we’re upping the ante by introducing a similar Incredible PBX LITE platform for CentOS® 7 with a few major enhancements. First, you get the new Asterisk® 16 LTS version which will keep you chugging along with bug fixes and security updates for the next 4+ years. Second, we’ve replaced FLITE with PicoTTS for a much improved (free) text-to-speech platform. And finally, we’ve added WebMin and all the other Incredible PBX components that make Incredible PBX incredible. Will there be a new release of Incredible PBX 16 with the FreePBX GUI modules? Absolutely. And there may be a few, new surprises along the way as well. Stay tuned!

    What’s Included? Despite its name, Incredible PBX LITE still serves up a VoIP powerhouse featuring Asterisk 16, an Apache web server, the latest MariaDB SQL server (formerly MySQL), SendMail, and most of the Incredible PBX feature set including SIP, SMS, Opus, voice recognition, PicoTTS Text-to-Speech VoIP applications plus fax support, Click-to-Dial, News, Weather, Reminders, and hundreds of features that typically are found in commercial PBXs: Conferencing, IVRs and AutoAttendants, Email Delivery of Voicemail, and much more.

    What’s Missing? We’ve removed the entire FreePBX GUI platform while retaining most of its design engineering and feature set. We’ve also eliminated the need to run a web server or database server although they’re still there. And gone are the days of having to configure extensions and trunks as well as inbound and outbound routes before you can actually use your PBX to make your first call. The tradeoff is a noticeable performance improvement.

    Choosing a SIP Provider. Incredible PBX LITE comes preconfigured to support five SIP extensions and four of the major SIP providers: Skyetel, VoIP.ms, V1VoIP, and Anveo Direct. We obviously hope you’ll choose Skyetel not only because they financially support Nerd Vittles and our open source projects, but also because it is a clearly superior platform offering crystal-clear communications and triple-redundancy so you never miss a call. Skyetel also sets itself apart from the other providers in the support department. They actually respond to issues, and there’s never a charge. As the old saying goes, they may not be the cheapest, but you get what you pay for. Even without taking advantage of Nerd Vittles half-price offer on up to $500 of Skyetel services, they’re still dirt cheap compared to the Bell Sisters and cable companies. Traditional DIDs are $1 per month. Outbound conversational calls are $0.012 per minute. Incoming conversational calls are a penny a minute, and CallerID lookups are $0.004. With all four providers, you only pay for minutes you use. Using more than one is a good idea.

    Choosing a Platform for Incredible PBX 16 LITE

    As with our other open source offerings, the platform choice for Incredible PBX 16 LITE depends upon a number of factors. For most folks, you’d be crazy to go out and purchase hardware to use in your home or office when cloud-based platforms are available for about a dollar a month. Unless you plan to publicly expose your server on the Internet to facilitate remote SIP connections, the OpenVZ offerings below are perfectly adequate while in business with the cautionary note that you need off-site backups AND a tested backup plan. Three providers previously listed have closed their doors in 2019. You’ve been warned.

    Installing Incredible PBX 16 LITE with CentOS 7

    If you’ve installed previous iterations of Incredible PBX, today’s drill is similar. Here is a thumbnail sketch of the install procedure for Incredible PBX 16 LITE. Begin by installing a minimal CentOS 7 (64-bit) platform or pick the CentOS 7 option with 1GB RAM and 20GB of storage from your cloud provider’s menu of choices. Then log into your server as root and issue the following commands:

    passwd
    yum -y update
    yum -y install net-tools nano wget tar
    wget http://incrediblepbx.com/incrediblepbx-16-LITE.tar.gz
    tar zxvf incrediblepbx-16-LITE.tar.gz
    rm -f incrediblepbx-16-LITE.tar.gz
    # to add swap file on non-OpenVZ cloud platforms with no swap file
    ./create-swapfile-DO
    # kick off Phase I install
    ./IncrediblePBX16-LITE.sh
    # after reboot, kick off Phase II install
    ./IncrediblePBX16-LITE.sh
    # add HylaFax/AvantFax, if desired
    ./incrediblefax13.sh
    # set desired timezone
    ./timezone-setup
    # set new extension passwords
    ./reset-extension-passwords
    # remember to enable TUN/TAP if using VPS Control Panel with OpenVZ
    # reconfigure PortKnocker if installing on an OpenVZ platform
    echo 'OPTIONS="-i venet0:0"' >> /etc/sysconfig/knockd
    service knockd restart
    # set up NeoRouter VPN client, if desired
    nrclientcmd
    # check network speed
    wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
    chmod +x speedtest-cli
    ./speedtest-cli
    

    Planning Ahead for That Rainy Day

    If you haven’t already learned the hard way, let us save you from a future shock. Hardware fails. All of it. So spend an extra hour now so that you’ll be prepared when (not if) disaster strikes. First, once you have your new PBX configured the way you plan to use it, make a backup of your PBX by running the Incredible Backup script: /root/incrediblebackup13

    Copy down the name of the backup file that was created. You’ll need it in a few minutes.

    Second, build yourself an identical VirtualBox platform on your desktop PC. It’s the same steps as outlined above.

    Next, create a /backup folder on your VirtualBox PBX and copy the backup file from your main server to your VirtualBox server and restore it after logging in to VirtualBox PBX as root:

    mkdir /backup
    scp root@main-pbx-ip-address:/backup/backup-file-name.tar.gz /backup/.
    /root/incrediblerestore13 /backup/backup-file-name.tar.gz
    

    Complaints that you "forgot" to make a backup and your hardware has failed or your provider has gone out of business are not welcomed. We’re sorry for your loss. Case closed.

    Completing the Incredible PBX Setup Procedure

    Unless your desktop PC and server are both on the same private LAN, the install procedure should be performed from a desktop PC using SSH or Putty. This will insure that your desktop PC is also whitelisted in the Incredible PBX firewall. Using the console to perform the install is NOT recommended as your desktop PC will not be whitelisted in the firewall. This may result in your not being able to log in to your server. Once you have network connectivity, log in to your server as root from a desktop PC using your root password. Accept the license agreement by pressing ENTER.

    Kick off the Phase I install. Once your server reboots and you log back in as root, start the Phase II install. All of your passwords will be randomly assigned with the exception of the root user Linux password. You can set it at any time by issuing the command: passwd. With the exception of your root user password, the remaining passwords can be displayed using the command: /root/show-passwords.

    Finally, if your PBX is sitting behind a NAT-based router, you’ll need to redirect incoming UDP 5060 and UDP 10000-20000 traffic to the private IP address of your PBX. This is required for all of the SIP providers included in the Incredible PBX LITE build. Otherwise, all inbound calls will fail.

    blank

    Configuring Skyetel for Incredible PBX 16 LITE

    If you’ve decided to go with Skyetel, here’s the drill. Sign up for Skyetel service and take advantage of the Nerd Vittles BOGO special. First, complete the Prequalification Form here. You then will be provided a link to the Skyetel site to complete your registration. Once you have registered on the Skyetel site and your account has been activated, open a support ticket and request the BOGO credit for your account by referencing the Nerd Vittles special offer. Skyetel will match your deposit of up to $250 which gets you up to $500 of helf-price calling. Credit is limited to one per person/company/address/location. Effective 10/1/2023, $25/month minimum spend required.

    Skyetel does not use SIP registrations to make connections to your PBX. Instead, Skyetel utilizes Endpoint Groups to identify which servers can communicate with the Skyetel service. An Endpoint Group consists of a Name, an IP address, a UDP or TCP port for the connection, and a numerical Priority for the group. For incoming calls destined to your PBX, DIDs are associated with an Endpoint Group to route the calls to your PBX. For outgoing calls from your PBX, a matching Endpoint Group is required to authorize outbound calls through the Skyetel network. Thus, the first step in configuring the Skyetel side for use with your PBX is to set up an Endpoint Group. Here’s a typical setup for Incredible PBX LITE:

    • Name: MyPBX
    • Priority: 1
    • IP Address: PBX-Public-IP-Address
    • Port: 5060
    • Protocol: UDP
    • Description: lite1.incrediblepbx.com

    To receive incoming PSTN calls, you’ll need at least one DID. On the Skyetel site, you acquire DIDs under the Phone Numbers tab. You have the option of Porting in Existing Numbers (free for the first 60 days after you sign up for service) or purchasing new ones under the Buy Phone Numbers menu option.

    Once you have acquired one or more DIDs, navigate to the Local Numbers or Toll Free Numbers tab and specify the desired SIP Format and Endpoint Group for each DID. Add SMS/MMS and E911 support, if desired. Call Forwarding and Failover are also supported. That completes the VoIP setup on the Skyetel side. System Status is always available here.

    Configuring VoIP.ms for Incredible PBX LITE

    To sign up for VoIP.ms service, may we suggest you use our signup link so that Nerd Vittles gets a referral credit for your signup. Once your account is set up, you’ll need to set up a SIP SubAccount and, for Authentication Type, choose Static IP Authentication and enter your Incredible PBX LITE server’s public IP address. For Transport, choose UDP. For Device Type, choose Asterisk, IP PBX, Gateway or VoIP Switch. Order a DID in their web panel, and then point the DID to the SubAccount you just created. Be sure to specify atlanta1.voip.ms as the POP from which to receive incoming calls.

    Configuring V1VoIP for Incredible PBX LITE

    To sign up for V1VoIP service, sign up on their web site. Then login to your account and order a DID under the DIDs tab. Once the DID has been assigned, choose View DIDs and click on the Forwarding button beside your DID. For Option #1, choose Forward to IP Address/PBX. For the Fowarding Address, enter the public IP address of your server. For the T/O (timeout) value, set it to 2o seconds. Then click the Update button. Under the Termination tab, create a new Endpoint with the public IP address of your server so that you can place outbound calls through V1VoIP.

    Configuring Anveo Direct for Incredible PBX LITE

    To sign up for Anveo Direct service, sign up on their web site and then login. After adding funds to your account, purchase a DID under Inbound Service -> Order DID. Next, choose Configure Destination SIP Trunk. Give the Trunk a name. For the Primary SIP URI, enter $[E164]$@server-IP-address. For Call Options, select your new DID from the list. You also must whitelist your public IP address under Outbound Service -> Configure. Create a new Call Termination Trunk and name it to match your server. For Dialing Prefix, choose six alphanumeric characters beginning with a zero. In Authorized IP Addresses, enter the public IP address of your server. Set an appropriate rate cap. We like $0.01 per minute to be safe. Set a concurrent calls limit. We like 2. For the Call Routing Method, choose Least Cost unless you’re feeling extravagant. For Routes/Carriers, choose Standard Routes. Write down your Dialing Prefix and then click the Save button.

    Before you can make outbound calls through Anveo Direct from your PBX, you first must configure the Dialing Prefix that you wrote down in the previous step. Newer downloads include an add-anveo-pin script to update your PIN in Incredible PBX. If you don’t have the script, login to your server as root and use nano to edit extensions_additional.conf in the /etc/asterisk directory. Search (Ctl-W) for anveo-pin and replace anveo-pin with the 6-digit alphanumeric PIN for your account. Press Ctrl-X, Y, then Enter to save your settings. Reload your dialplan with the command: asterisk -rx "dialplan reload"

    Configuring a Softphone for Incredible PBX LITE

    We’re in the home stretch now. You can connect virtually any kind of telephone to your new PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony.

    We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You can find them by running /root/show-passwords. You’ll need the IP address of your server plus your extension 701 password. In the YateClient, fill in the blanks using the IP address of your Server, 701 for your Username, and whatever Password was assigned to the extension when you installed Incredible PBX. Click OK to save your entries.

    blank

    Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

    Audio Issues with Incredible PBX LITE

    Only if you experience one-way or no audio on some calls, add your external IP address and LAN subnet in /etc/asterisk/sip_general_custom.conf like the following example:

    nat=force_rport,comedia
    externip=xxx.xxx.xxx.xxx
    localnet=192.168.0.0/255.255.0.0 
    

    Then issue the following commands:

    sed -i 's|nat=no|nat=force_rport,comedia|' /etc/asterisk/sip_additional.conf
    systemctl restart asterisk
    

    Displaying Formatted CDR Data

    By default, web access is limited to whitelisted IP addresses so it’s safe to access your Call Detail Report (CDR) using a browser. Unfortunately, the only browser that currently handles this with automatic formatting is Firefox. To begin, install the FireCSV extension in Firefox. Next, log in to your server as root and change to the /var/www/html folder. Issue the command ln -s /var/log/asterisk/cdr-csv/Master.csv mycdr.csv to create a symlink to your CSV data. Now you can access your CDR data with Firefox by navigating to http://server-ip/mycdr.csv.

    There’s also a simple way to display CSV files from the Linux command line using this tip from StackOverflow:

    column -s, -t < /var/log/asterisk/cdr-csv/Master.csv | less -#2 -N -S
    

    Incredible PBX LITE Administration

    We've eased the pain of administering your new PBX with a collection of scripts which you will find in the /root folder after logging in with SSH or Putty. Here's a quick summary of what each of the scripts does.

    add-fqdn is used to whitelist a fully-qualified domain name in the firewall. Because Incredible PBX LITE blocks all traffic from IP addresses that are not whitelisted, this is what you use to authorize an external user for your PBX. The advantage of an FQDN is that you can use a dynamic DNS service to automatically update the IP address associated with an FQDN so that you never lose connectivity.

    add-ip is used to whitelist a public IP address in the firewall. See the add-fqdn explanation as to why this matters.

    del-acct is used to remove an IP address or FQDN from the firewall's whitelist.

    add-anveo-pin is used to add or update your Anveo Direct outbound calling PIN.

    reset-conference-pins is a script that automatically and randomly resets the user and admin pins for access to the preconfigured conferencing application. Dial C-O-N-F from any registered SIP phone to connect to the conference.

    reset-extension-passwords is a script that automatically and randomly resets ALL of the SIP passwords for extensions 701-705. Be careful using this one, or you may disable existing registered phones and cause Fail2Ban to blacklist the IP addresses of those users. HINT: You can place a call to the Ring Group associated with all five extensions by dialing 777.

    reset-reminders-pin is a script that automatically and randomly resets the pin required to access the Telephone Reminders application by dialing 123. It's important to protect this application because a nefarious user could set up a reminder to call a number anywhere in the world assuming your SIP provider's account was configured to allow such calls.

    show-feature-codes is a cheat sheet for all of the feature codes which can be dialed from any registered SIP phone. It documents how powerful a platform Incredible PBX 16 LITE actually is.

    show-passwords is a script that displays ALL of the passwords associated with Incredible PBX 16 LITE. This includes SIP extension passwords, voicemail pins, conference pins, telephone reminders pin, and your Anveo Direct outbound calling pin (if configured). Note that voicemail pins are configured by the user of a SIP extension the first time the user accesses the voicemail system by dialing *97.

    update-IncrediblePBX is the Automatic Update Utility which checks for server updates from incrediblepbx.com every time you log into your server as root using SSH or Putty. Do NOT disable it as it is used to load important fixes and security updates when necessary. We recommend logging into your server at least once a week.

    pbxstatus (shown above) displays status of all major components of Incredible PBX 16 LITE.

    Call Detail Records available in spreadsheet format at /var/log/asterisk/cdr-csv/Master.csv.

    Forwarding Calls to Your Cellphone. Keep in mind that inbound calls to your DIDs automatically ring all five SIP extensions, 701-705. The easiest way to also ring your cellphone is to set one of these five extensions to forward incoming calls to your cellphone. After logging into your PBX as root, issue the following command to forward calls from extension 705 to your cellphone: asterisk -rx "database put CF 705 6781234567"

    To remove call forwarding: asterisk -rx "database del CF 705"

    Introducing Incredible PBX LITE featuring Raspbian 10

    blank

    As you may know, the Raspberry Pi Foundation introduced the $35 Raspberry Pi 4 last week. In addition to jaw-dropping hardware enhancements, the introduction also included the new Raspbian 10 (Buster) platform which was surprising since Debian 10 isn’t scheduled for official release until the end of this week. As with prior releases, Raspbian 10 brought with it some major headaches for the VoIP community not the least of which is FreePBX® cannot (yet) be installed. But sometimes there’s a silver lining accompanying bad news.

    Several Debian 10 issues caused us to rethink what a VoIP platform for the Raspberry Pi actually should look like. After all, most Raspberry Pi hobbyists aren’t interested in mastering the intricacies of Asterisk® and FreePBX. They’re more concerned with a stable, fast VoIP communications platform that’s easy to deploy and will operate without hiccups in a home or small office environment. Thus was born Incredible PBX LITE, a new turnkey VoIP platform that requires zero configuration out of the box and supports five SIP telephones and up to four trunk providers for low-cost worldwide calling. Simply sign up with one of these VoIP service providers, acquire a telephone number (DID), enter the IP address of your PBX, and you can instantly make and receive calls using up to five SIP telephones or softphones.

    UPDATE: If you’d prefer the full-featured Incredible PBX 16-15 for the Raspberry Pi, it’s now available here as well.

    What’s Included? Despite its name, Incredible PBX LITE still serves up a VoIP powerhouse featuring Asterisk 13, an Apache web server, the latest MariaDB SQL server (formerly MySQL), SendMail, and most of the Incredible PBX feature set including SIP, SMS, Opus, voice recognition, FLITE Text-to-Speech VoIP applications plus fax support, Click-to-Dial, News, Weather, Reminders, and hundreds of features that typically are found in commercial PBXs: Conferencing, IVRs and AutoAttendants, Email Delivery of Voicemail, Voicemail Blasting…

    What’s Missing? We’ve removed the entire FreePBX GUI platform while retaining most of its feature set. We’ve also eliminated the need to run a web server or database server although they’re still there. And gone are the days of having to configure extensions and trunks as well as inbound and outbound routes before you can actually use your PBX to make your first call. The tradeoff is a noticeable performance improvement. While a Raspberry Pi 4 isn’t required to run Incredible PBX LITE, doing so provides another three-fold performance boost compared to a Raspberry Pi 3B+. Simply stated, Incredible PBX LITE performance now rivals what you would expect on a powerful cloud-based platform such as Digital Ocean or Vultr.

    Choosing a SIP Provider. As we mentioned, Incredible PBX LITE comes preconfigured to support four of the major SIP providers: Skyetel, VoIP.ms, V1VoIP, and Anveo Direct. We obviously hope you’ll choose Skyetel not only because they financially support Nerd Vittles and our open source projects, but also because it is a clearly superior platform offering crystal-clear communications and triple-redundancy so you never miss a call. Skyetel also sets itself apart from the other providers in the support department. They actually respond to issues, and there’s never a charge. As the old saying goes, they may not be the cheapest, but you get what you pay for. Even without taking advantage of Nerd Vittles half-price offer on up to $500 of Skyetel services, they’re still dirt cheap compared to the Bell Sisters and cable companies. Traditional DIDs are $1 per month. Outbound conversational calls are $0.012 per minute. Incoming conversational calls are a penny a minute, and CallerID lookups are $0.004. With all four providers, you only pay for minutes you use. Using more than one is a good idea. Effective 10/1/2023, $25/month minimum spend required.

    Assembling the Required Raspberry Pi Components

    Before you can deploy Incredible PBX LITE, you’ll first need the necessary Raspberry Pi hardware. Here’s the short list and, if you’re in a hurry, the $35 Raspberry Pi 3B+ will cost you less than $3 extra to get it quickly from Amazon using our referral link. If you prefer to wait for a Raspberry Pi 4, read on. Either way, the RasPi remains one of the world’s best bargains! Assuming you already own an HDMI-compatible monitor and a USB keyboard

  • Raspberry Pi 4B from a Raspberry Pi reseller
  • $8 15.3W USB-C RasPi 4 (only) Power Supply
  • $8 32GB microSDHC Class 10 card (strongly recommended!)
  • $5 Official RasPi 4 Case
  • Getting Started with Incredible PBX LITE

    Here’s everything to know about installation and setup. "Automatic" means just watch. Steps #1 and #2 are self-explanatory. For the remaining steps, we’ll further document the procedures in the sections below.

    1. Download and unzip Incredible PBX LITE image from SourceForge
    2. Transfer Incredible PBX LITE image to microSD card
    3. Boot Raspberry Pi from new microSD card (16GB minimum)
    4. Login to RasPi console as root:password to initialize your server (Automatic)
    5. In raspi-config Advanced Options, Expand FileSystem to fill your SD card
    6. In Localization Options, set Locale, TimeZone, Keyboard, & WiFi Country
    7. Reboot after writing down your server IP address (Automatic)
    8. Login via SSH or Putty as root:password to set passwords & setup firewall (Automatic)
    9. Register for and configure at least one trunk provider for Incredible PBX LITE
    10. Install Incredible Fax: /root/incrediblefax13_raspi3.sh (Credentials: admin:password)

    First Boot of Incredible PBX LITE with Wi-Fi

    Incredible PBX LITE requires Internet connectivity to complete its automated install. If you’re using a wired network connection, you can skip to the next section. With the Raspberry Pi 3B and 4B, WiFi is built into the hardware. But you still have to insert your SSID name and SSID password to make a connection to your WiFi network. To do so, follow these next steps carefully. Insert the Incredible PBX LITE microSD card into your Raspberry Pi 3 or 4 and apply power to the hardware. When the bootup procedure finishes, login as root with the default password: password. At the first prompt, DO NOT PRESS THE ENTER KEY! Instead, press Ctrl-C to break out of the setup script. At the command prompt, issue the following commands to bring up the WiFi config file:

    cd /etc/wpa_supplicant
    nano -w wpa_supplicant.conf
    

    If your WiFi network does not require a password, then uncomment the four lines below and save the file: Ctrl-X, Y, then Enter. Now restart your server: reboot. When the reboot finishes, you now should have network connectivity.

    network={
     key_mgmt=NONE
     priority=1
    }
    

    If your WiFi network requires a password, scroll down to the SSID entry and replace YourSSID with the actual SSID of your WiFi network. Make sure you preserve the entry with the quotes as shown. Next, replace YourSSIDpassword with the SSID password of your WiFi network. Save the file: Ctrl-X, Y, then Enter. Now restart your server: reboot. When the reboot finishes, you now should have network connectivity.

    Once the reboot process finishes, you should see an entry on about the middle line displayed on your monitor which reads: "My IP address is…". Write down the IP address shown. You’ll need it in a minute. Skip the next section since you are using a WiFi connection.

    If you don’t see an IP address assigned to your server, then correct the network deficiency (invalid WiFi credentials, DHCP not working, Internet down), and reboot until you see an IP address assigned to your server. DO NOT PROCEED WITHOUT AN ASSIGNED IP ADDRESS.

    First Boot of Incredible PBX Using Wired Connection

    Incredible PBX LITE requires Internet connectivity to complete its automated install. After connecting your server to your local network with a network cable, insert the Incredible PBX LITE microSD card into your Raspberry Pi and apply power to the hardware. When the bootup procedure finishes, you should see an entry on about the middle line displayed on your monitor which reads: "My IP address is…". Write down the IP address shown. You’ll need it in the next step.

    If you don’t see an IP address assigned to your server, then correct the network deficiency (cable not connected, DHCP not working, Internet down), and reboot until you see an IP address assigned to your server. DO NOT PROCEED WITHOUT AN ASSIGNED IP ADDRESS.

    Completing the Incredible PBX Initialization Procedure

    Unless your desktop PC and RasPi are both on the same private LAN, the remainder of the install procedure should be completed from a desktop PC using SSH or Putty. This will assure that your desktop PC is also whitelisted in the Incredible PBX firewall. Using the console to complete the install is NOT recommended as your desktop PC will not be whitelisted in the firewall. This may result in your not being able to log in to your server. Once you have network connectivity, log in to your server as root from a desktop PC using the default password: password. Accept the license agreement by pressing ENTER. You then will be redirected to raspi-config. This is the utility used to expand your Incredible PBX LITE image to use your entire microSD card. If you fail to complete this step, your microSD card will be restricted to 16GB. In the raspi-config utility, choose Localization Options and set Locale, TimeZone, Keyboard, & WiFi Country. Then choose Advanced Options. All of the defaults should be satisfactory with the exception of the first item: Expand Filesystem. Choose this option and activate the resizing directive. Review the other items and then exit and reboot.

    Once your server reboots and you log back in as root, all of your passwords will be randomly assigned with the exception of the root user Linux password. You can set it by issuing the command: passwd. With the exception of your root user password, the remaining passwords can be displayed using the command: /root/show-passwords.

    Finally, if your PBX is sitting behind a NAT-based router, you’ll need to redirect incoming UDP 5060 and UDP 10000-20000 traffic to the private IP address of your PBX. This is required for all of the SIP providers included in the Incredible PBX LITE build. Otherwise, all inbound calls will fail.

    SECURITY ALERT: There was a configuration error in the initial setup which leaves the firewall deactivated. This gets corrected by the Incredible PBX Automatic Update Utility the next time you login to your server as root. Please do so immediately.

    Configuring Skyetel for Incredible PBX LITE

    If you’ve decided to go with Skyetel, here’s the drill. Sign up for Skyetel service and take advantage of the Nerd Vittles BOGO special. First, complete the Prequalification Form here. You then will be provided a link to the Skyetel site to complete your registration. Once you have registered on the Skyetel site and your account has been activated, open a support ticket and request the BOGO credit for your account by referencing the Nerd Vittles special offer. Skyetel will match your deposit of up to $250 which gets you up to $500 of helf-price calling. Credit is limited to one per person/company/address/location.

    Skyetel does not use SIP registrations to make connections to your PBX. Instead, Skyetel utilizes Endpoint Groups to identify which servers can communicate with the Skyetel service. An Endpoint Group consists of a Name, an IP address, a UDP or TCP port for the connection, and a numerical Priority for the group. For incoming calls destined to your PBX, DIDs are associated with an Endpoint Group to route the calls to your PBX. For outgoing calls from your PBX, a matching Endpoint Group is required to authorize outbound calls through the Skyetel network. Thus, the first step in configuring the Skyetel side for use with your PBX is to set up an Endpoint Group. Here’s a typical setup for Incredible PBX LITE:

    • Name: MyPBX
    • Priority: 1
    • IP Address: PBX-Public-IP-Address
    • Port: 5060
    • Protocol: UDP
    • Description: lite1.incrediblepbx.com

    To receive incoming PSTN calls, you’ll need at least one DID. On the Skyetel site, you acquire DIDs under the Phone Numbers tab. You have the option of Porting in Existing Numbers (free for the first 60 days after you sign up for service) or purchasing new ones under the Buy Phone Numbers menu option.

    Once you have acquired one or more DIDs, navigate to the Local Numbers or Toll Free Numbers tab and specify the desired SIP Format and Endpoint Group for each DID. Add SMS/MMS and E911 support, if desired. Call Forwarding and Failover are also supported. That completes the VoIP setup on the Skyetel side. System Status is always available here.

    Configuring VoIP.ms for Incredible PBX LITE

    To sign up for VoIP.ms service, may we suggest you use our signup link so that Nerd Vittles gets a referral credit for your signup. Once your account is set up, you’ll need to set up a SIP SubAccount and, for Authentication Type, choose Static IP Authentication and enter your Incredible PBX LITE server’s public IP address. For Transport, choose UDP. For Device Type, choose Asterisk, IP PBX, Gateway or VoIP Switch. Order a DID in their web panel, and then point the DID to the SubAccount you just created. Be sure to specify atlanta1.voip.ms as the POP from which to receive incoming calls.

    Configuring V1VoIP for Incredible PBX LITE

    To sign up for V1VoIP service, sign up on their web site. Then login to your account and order a DID under the DIDs tab. Once the DID has been assigned, choose View DIDs and click on the Forwarding button beside your DID. For Option #1, choose Forward to IP Address/PBX. For the Fowarding Address, enter the public IP address of your server. For the T/O (timeout) value, set it to 2o seconds. Then click the Update button. Under the Termination tab, create a new Endpoint with the public IP address of your server so that you can place outbound calls through V1VoIP.

    Configuring Anveo Direct for Incredible PBX LITE

    To sign up for Anveo Direct service, sign up on their web site and then login. After adding funds to your account, purchase a DID under Inbound Service -> Order DID. Next, choose Configure Destination SIP Trunk. Give the Trunk a name. For the Primary SIP URI, enter $[E164]$@server-IP-address. For Call Options, select your new DID from the list. You also must whitelist your public IP address under Outbound Service -> Configure. Create a new Call Termination Trunk and name it to match your server. For Dialing Prefix, choose six alphanumeric characters beginning with a zero. In Authorized IP Addresses, enter the public IP address of your server. Set an appropriate rate cap. We like $0.01 per minute to be safe. Set a concurrent calls limit. We like 2. For the Call Routing Method, choose Least Cost unless you’re feeling extravagant. For Routes/Carriers, choose Standard Routes. Write down your Dialing Prefix and then click the Save button.

    Before you can make outbound calls through Anveo Direct from your PBX, you first must configure the Dialing Prefix that you wrote down in the previous step. Login to your server as root and use nano to edit extensions_additional.conf in the /etc/asterisk directory. Search (Ctl-W) for anveo-pin and replace anveo-pin with the 6-digit alphanumeric PIN for your account. Press Ctrl-X, Y, then Enter to save your settings. Reload your dialplan with the command: asterisk -rx "dialplan reload"

    Audio Issues with Incredible PBX LITE

    Only if you experience one-way or no audio on some calls, add your external IP address and LAN subnet in /etc/asterisk/sip_general_custom.conf like the following example:

    nat=yes
    externip=xxx.xxx.xxx.xxx
    localnet=192.168.0.0/255.255.0.0 
    

    Then restart Asterisk: systemctl restart asterisk

    proximity is a script used in conjunction with bluetooth to decipher whether your smartphone is within range of your server. If not, the script forwards calls to extension 701 to an extension or external smartphone of your choice. Edit the proximity script to add your preferences. Then uncomment the proximity line in /etc/crontab. Complete setup details on setup are available in our previous tutorial.

    reset-conference-pins is a script that automatically and randomly resets the user and admin pins for access to the preconfigured conferencing application. Dial C-O-N-F from any registered SIP phone to connect to the conference.

    reset-extension-passwords is a script that automatically and randomly resets ALL of the SIP passwords for extensions 701-705.
