The Most Versatile VoIP Provider: FREE PORTING

A New Incredible PBX 2027 Image for the Raspberry Pi



Are you looking for a powerful and affordable VoIP phone system for your home or small business? Incredible PBX 2027 is the perfect solution especially when tied to an inexpensive platform such as the Raspberry Pi. Earlier this year we introduced a new Incredible PBX 2027 installer for the Raspberry Pi. But we heard from many of you that it was simply too time-consuming to go through both the installation of the Raspberry Pi OS and then the Incredible PBX 2027 setup. This is particularly important to those that use the Raspberry Pi as a teaching platform because of the lengthy install process. So today we are pleased to introduce a Raspberry Pi image for the Raspberry Pi 4 and 400 that installs almost instantaneously after burning the image to a microSD card.

Assembling the Required Raspberry Pi Components

Before you can deploy Incredible PBX 2027, you’ll first need the necessary Raspberry Pi hardware. To support the enhanced Incredible PBX 2027 platform, we strongly recommend either the Raspberry Pi 400 or the Raspberry Pi 4B with at least 2GB RAM. You can choose a reseller below for quicker delivery. Assuming you already own an HDMI-compatible monitor and a USB keyboard (only required if you don’t buy a RasPi 400)…

  • Raspberry Pi 4B or Raspberry Pi 400
  • $10 USB-C RasPi 4 (only) Power Supply
  • $9 32GB microSDHC Class 10 card (strongly recommended!)
  • $5 Official RasPi 4B Case or go here for our favorite
  • Getting Started with Incredible PBX 2027

    Unlike the previous setup process, you cannot use the Raspberry Pi Imager to create your microSD card. Instead, we recommend the free Balena Etcher application which is available for all desktops. So begin by installing the Balena Etcher software here.

    Next, download and unzip the Incredible PBX 2027 image from the Incredible PBX Repo.

    If you don’t already have one, we recommend you purchase the $9.99 SD Card Reader using our referral link. Then insert a 32GB microSD card into the reader and plug the reader into your desktop machine. Using our referral links helps fund our open source projects.


    Now run the Balena Etcher app. Choose Flash from File and select the unzipped Incredible PBX 2027 image from your desktop: incrediblepbx2027-raspi.img. Next, choose Select Target and choose the microSD card you plugged into your PC. Finally, click Flash to transfer the Incredible PBX 2027 image to your microSD card. When the process completes, eject the microSD card and insert it into and boot your Raspberry Pi.


    If flashing fails, try formatting the microSD card on a Linux machine first. Format: mkfs.vfat /dev/sda. Or Reformat: mkfs.vfat /dev/sda1 Then repeat the Etcher flashing.

    After your Raspberry Pi boots, do the following:

    1. Press ENTER to display Login prompt. Login as root with password: password
    2. Agree to license terms by pressing ENTER
    3. When initial setup completes, press ENTER
    4. When raspi-config begins:
    5. What user should use these settings? Press ENTER
    6. System Options -> Wireless LAN: Configure SSID and Password, if desired
    7. Localization Settings: Set Locale, Timezone & WiFi Country
    8. Advanced Options: Resize image to match SD card size
    9. Finish -> Reboot Now: YES
    10. If rc.local fails to start after rebooting, press Ctrl-Alt-Del to reboot again
    11. Wait for Asterisk to finish starting up. Then switch to your Desktop PC
    12. Make note of the Private IP address above RasPi login prompt before you go

    To assure that your desktop computer is whitelisted in the Incredible PBX firewall, we recommend completing the rest of the install using SSH or Putty on your desktop machine. The ip a command above will tell you the local IP address of your RasPi. So login using this command and default password of password: ssh root@ip-address.

    1. Set secure root password with command: passwd
    2. Set secure FreePBX password: /root/admin-pw-change
    3. Set secure Apache password: /root/apache-pw-change
    4. /root/reset-extension-passwords (701 to 705)
    5. /root/reset-conference-pins
    6. /root/reset-reminders-pin
    7. Make note of your PortKnocker codes: cat knock.FAQ
    8. DONE!

    When the install finishes, reboot your Raspberry Pi and log back in as root. Let the Automatic Update Utility bring your system up to current specs after which the pbxstatus display should show something like the following.


    NOTE: To activate an OpenVPN client connection, create and copy a client configuration named incrediblepbx2027.ovpn from your OpenVPN server into the /etc folder & reboot.

    What’s Included? Incredible PBX 2027 serves up a never before available VoIP powerhouse featuring Asterisk 20 and all FreePBX 16 GPL modules, an Apache web server, the latest MariaDB SQL server (formerly MySQL), SendMail mail server, Webmin, and most of the Incredible PBX feature set including SIP, PJSIP, SMS, voice recognition, AsteriDex, gTTS Text-to-Speech VoIP applications, Call-By-Name Dialing, News, Weather, Telephone Reminders, and hundreds of features that typically are found in commercial PBXs: Conferencing, IVRs and Email Delivery of transcribed voicemails, AutoAttendants, 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 our VoIP providers and start making and receiving calls instantly. Or you can use the new ClearlyIP trunking module included in the GUI for seamless integration of SMS messaging into FreePBX® and its User Control Panel.

    Choosing a SIP Provider. As we mentioned, Incredible PBX 2027 comes preconfigured to support many of the major SIP providers including those that financially support Nerd Vittles and our open source projects: ClearlyIP, Skyetel, and VoIP.ms. As the old saying goes, they may not be the cheapest, but you get what you pay for. With all our providers, you only pay for minutes you use so signing up with more than one provider is a smart idea. For the full list of supported VoIP providers, visit the Incredible PBX Wiki.

    Continuing Your Incredible PBX 2027 Journey

    If you entered WiFi credentials when running raspi-config above and your Raspberry Pi does not have a wired network connection, it should automatically enable the Wi-Fi connection on reboot. Issuing the command ip a will tell you the local IP addresses of wlan0 and eth0. With the Raspberry Pi 3B, 4B and 400, WiFi is built into the hardware. But you still have to provide your SSID name and SSID password to make a connection to your WiFi network. If pbxstatus does not show a network connection, here’s how to enable Wi-Fi:

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

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

     

    Now restart your server: reboot. When the reboot finishes, you now should have network connectivity.

    You may also need to change the default PortKnocker setting to your wireless LAN connection:

    sed -i 's|eth0|wlan0|' /etc/default/knockd
    service knockd restart
    

     

    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 RasPi. This is required for all of the SIP providers included in the Incredible PBX 2027 build. Otherwise, all inbound calls will fail.

    Configuring Skyetel for Incredible PBX 2027

    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. Effective 10/1/2023, $25/month minimum spend required.

    Skyetel typically does not require 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 2027:

    • Name: MyPBX
    • Priority: 1
    • IP Address: PBX-Public-IP-Address
    • Port: 5061
    • Protocol: UDP
    • Description: 2027.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 2027

    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 2027 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. On the Incredible PBX side, simply Enable the VoIPms trunk and save your update.

    Adding a Bootable SSD to Raspberry Pi

    Shown below are the two components that make up the 256GB storage solution for the Raspberry Pi. These include the M.2 SSD SATA drive and the M.2 enclosure which provides a USB connector that’s compatible with your RasPi. Assembly of the components takes less than a minute as shown in the steps below:




    You can order the M.2 SSD SATA drive and the M.2 enclosure using our Amazon referral links which help support Nerd Vittles and the Incredible PBX open source project.

    Once you have assembled your SSD in the sleeve, log back in as root using SSH or Putty. For best performance, insert the SSD drive into one of the blue USB 3.0 ports and verify that /dev/sda device is shown when you issue the command: fdisk -l

    Now proceed with the following steps to copy the image from your microSD card to the new SSD SATA drive:

    rpi-clone -l -e sda -f sda
    # answer prompts with yes and incred2027
    # once the image is copied, dismount the drive when prompted
    mount /dev/sda2 /mnt/clone
    cd /mnt/clone/boot
    cp -p -r /boot/* .
    sed -i 's|sda2|mmcblk0p2|' /boot/cmdline.txt
    cd /
    umount /mnt/clone
    halt
    

     
    Now you’re ready to restart your Raspberry Pi from the SSD SATA drive. Remove the microSD card and reboot your server.



    Configuring a Softphone for Incredible PBX 2027



    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. This really is not an option with a Raspberry Pi. 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 Zoiper5 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 VoIP-Info.org Forum when you’re ready to get serious about VoIP telephony.

    We recommend the Zoiper5 softphone which has a free option. Download it from here for your desktop of choice. Once installed, run it and ignore the nag screen for the commercial version. There are four screens (shown above) to navigate through to connect your softphone to your PBX. You’ll need the credentials for the 701 extension on Incredible PBX. You can find them by running /root/show-passwords or you can decipher the password in the FreePBX GUI by navigating to Applications -> Extensions -> 701 once you log in with your admin password which you set up above. You’ll also need the IP address of your server which you can decipher by running pbxstatus. In the first screen shown above, fill in your 701 SIP address making sure to add the 5061 port since this is a PJsip extension. Enter your Password and click the Login button. On the second and third screens, leave the defaults and click Next then Skip. On the final screen, Zoiper5 will check for connections SIP TLS, SIP TCP, SIP UDP, and IAX UDP. You should see a green Found indicator for SIP UDP which means your connection was successfully established. Press Next and you’ll have a working softphone.



    Now test things out by dialing 947 for a weather report using the Zoiper5 dialpad. You’ll be prompted to enter a 5-digit zip code. Note that this must be entered using the dialpad in the right window, NOT the original dialpad. You can try a few more calls to test things out:

    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 2027

    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. Equally important, check your Router settings and verify that SIP ALG is Disabled.

    Configuring Gmail as 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. IMPORTANT: You MUST use a Gmail App Password instead of your Gmail account password.

    /root/enable-gmail-smarthost-for-sendmail
    

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

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

    Almost-Free SMS Messaging Returns

    As you probably know, new Application To Person, 10 Digit Long Code (A2P 10DLC) SMS rules have gone into effect to lessen the chances of SPAM inundating the cellphone providers. As a result, SMS pricing from many VoIP providers has become prohibitively expensive. One provider that has not changed their pricing structure is VoIP.ms where SMS messages remain $0.0075 per message. While VoIP.ms provides a web interface to send and receive SMS messages, Incredible PBX also includes a command-line interface to their service. The recommended setup is to use the VoIP.ms side to forward incoming SMS messages to either your email account and/or cellphone. Then you can send SMS messages from both the VoIP.ms web portal AND the command line interface of Incredible PBX. To get started…

    On the VoIP.ms portal, do the following:

    1. Sign up for a VoIP.ms account using our referral link1
    2. Purchase a DID
    3. In the Message Service DID section, enable SMS/MMS and…
    4. Also provide email and/or cellphone forwarding numbers
    5. In Main Menu/SOAP/RestAPI, enable API and…
    6. Also create a very secure API password and…
    7. Provide IP address whitelist for receiving API messages

    On your Incredible PBX platform, login using SSH root and do the following:

    1. apt install php-soap -y
    2. cd /root/sms-voip.ms
    3. nano -w class.voipms.php
    4. Insert VoIP.ms username (email address) and API password
    5. Save file: Ctrl-X, Y, then ENTER
    6. nano -w voipms-sms.php
    7. Insert 10-digit DID in $SMSsender
    8. Save file: Ctrl-X, Y, then ENTER

    Now you’re ready to try things out. Simply enter the recipient’s 10-digit phone number and the desired message using the syntax below. The script should confirm transmission of the the message.

    /root/sms-voip.ms/voipms-sms.php smsnumber "sms message"
    

    Incredible PBX 2027 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.

    add-fqdn is used to whitelist a fully-qualified domain name in the firewall. Because Incredible PBX 2027 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.

    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.

    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.


    rpi-clone is a utility that makes it easy to make a bootable image of the microSD card used to start your Raspberry Pi. You’ll need a USB-to-microSD adapter to begin. Insert a backup microSD card large enough to hold all of the data on the primary microSD card (df -h). Insert the USB stick with the card. Identify the backup microSD card, usually sda (fdisk -l). Format the backup microSD card: mkfs.vfat /dev/sda. Or reformat: mkfs.vfat /dev/sda1. Then issue the following command to clone the main microSD card: rpi-clone -f sda. Tutorial here.

    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 2027 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 2027. 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.

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

    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.

    upgrade-asterisk20 is self-explanatory and can be used to upgrade to the latest release of Asterisk 20.

    pbxstatus (shown above) displays status of all major components of Incredible PBX 2027.

    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. You must have a working trunk for calls to your cellphone to complete successfully. 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" where 6781234567 is your cellphone number.

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

    Keeping FreePBX 16 Modules Current

    We strongly recommend that you periodically update all of your FreePBX modules to eliminate bugs and to reduce security vulnerabilities. Make a backup image with rpi-clone first! From the Linux CLI, log into your server as root and issue the following commands:

    rm -f /tmp/*
    fwconsole ma upgradeall
    fwconsole reload
    /root/sig-fix
    systemctl restart apache2
    /root/sig-fix
    

    Resolving an Expired Certificate Alert

    1. Navigate to Admin -> Certificate Management in the FreePBX GUI
    2. Click the Trashcan to delete the Self-Signed Certificate
    3. Click New Certificate -> Generate Self-Signed Certificate
    4. In the Description field, type: Default
    5. Click Generate Certificate button

    Introducing Adminer: The Ultimate MySQL Editor

    If you’re as sick of phpMyAdmin as we are, you’ll be happy to know there’s a new kid on the block, Adminer. Better yet, the install procedure is a painless, one-minute exercise. The setup procedure for Incredible PBX 2027 is documented here. Once installed, you can connect to Adminer at http://server-ip-address/adminer. You should be prompted for your Apache admin credentials which were configured when you first installed Incredible PBX. Next, enter your MySQL root credentials and Adminer will display in all its glory. DO NOT OPEN PORT 80 FOR PUBLIC ACCESS, OR YOUR ENTIRE PBX WILL BE AT A HACKER’S MERCY!


    What About Fax Support?

    Incredible PBX 2027 no longer includes fax support out of the box. To add it, follow this tutorial.

    Interconnecting Incredible PBX Servers with PJsip


    Much has been made of the lack of multi-tenant functionality with Asterisk® and FreePBX®. Today we’ll show you how to interconnect as many Asterisk servers as you like and make transparent calls between all of them at zero cost. Setup time is under 5 minutes per server. When you couple PBXs with distributed infrastructure and inexpensive cloud servers costing $25 or less a year and on-premise virtual machine platforms including Proxmox, VMware ESXi, VirtualBox, Windows 11 WSL, and Mac UTM, it makes little sense in terms of reliability and redundancy to put all your eggs in one basket with a MultiTenant telephony solution.

    PJsip Interconnection Design

    Our basic design goes like this. Create as many decentralized Incredible PBX platforms as you need to cover the various locations of your business. Whether that’s two cities or eighty-nine, the design is the same. Next, use the same extension design at every site. For example, in each location choose 3-digit extensions in the 100 range for management offices and the receptionist, in the 200 range for human resources, in the 300 range for IT services, and so on. Next, number your locations. For nine or fewer cities, use single digits. For up to 89, use two digits beginning with 10. We actually use the last octet of our server’s OpenVPN IP address for the dialing prefix. For our example, we’ll use 1 for the Atlanta office, 2 for Dallas, and 3 for Boston. When someone in Atlanta wishes to call the main human resources number in Dallas, the user would dial 2200. For Boston, they’d dial 3200. And, when someone in Dallas or Boston wishes to reach the main HR number in Atlanta, they’d dial 1200. Assuming the receptionist in each location has extension 100, callers in Dallas would dial 1100 for Atlanta and 3100 for Boston. Hopefully, you get the idea now. Sketch these out on a piece a paper until it all makes sense to you.

    You’ll need static IP addresses for each of your Incredible PBX servers. But, if one or more of your servers are sitting behind a corporate firewall, that’s not a deal breaker. Simply set up an OpenVPN network and assign a private OpenVPN IP address to each server. Then use these OpenVPN IP addresses in interconnecting your servers rather than static, public IP addresses. OpenVPN addresses are automatically whitelisted in the Incredible PBX firewall. For other IP addresses, you’ll need to whitelist them using the add-ip utility in the /root folder of each of your PBXs. Be sure to also add the IP addresses of the servers to the ignoreip list in /etc/fail2ban/jail.conf. Note in our design that, for security reasons, PJsip trunks must be created on BOTH the sending and receiving PBXs before interconnected calls between the servers will successfully complete. You wouldn’t want strangers making PJsip calls through your servers. In the alternative, if you only want to enable outbound calls from one PBX to another, you can avoid creating a PJsip trunk on the destination server and instead enable Outbound Authentication on the originating server. In this case, you also will need to enter extension credentials from the destination server in the PJsip Username and Secret fields. But let’s continue on assuming you want calls to flow in both directions.

    Using our 3-city example, let’s begin by configuring the Atlanta PBX using the FreePBX GUI. Login to the web interface as admin and navigate to Connectivity -> Trunks. We want to create two PJsip trunks, one to connect to Dallas and another to connect to Boston. Similarly, in Dallas, we’ll create PJsip trunks for Atlanta and Boston. And, in Boston, we’ll create PJsip trunks for Atlanta and Dallas.

    Configuring PJsip Trunks For Each Location

    On the Atlanta PBX, click the Add Trunk button and choose Add SIP (chan_pjsip) Trunk. For the first PJsip trunk, in the General tab, let’s keep it simple and enter Trunk Name as Dallas. Leave the remaining default settings and click the pjSIP Settings tab. Leave all of the default settings as they are in both the Advanced and Codecs tabs. In the General tab, change the Authentication and Registration settings to None. For the SIP Server IP address, enter the IP address (or OpenVPN address) of the Dallas server. For the SIP Server Port, enter 5061. Finally, change the Context entry to from-internal. That’s all the settings you’ll need. So click Submit and Apply Config when prompted. Repeat the drill for Boston.


    Configuring Outbound Routes For Each Location

    Next, we need to create two Outbound Routes for calls to Dallas and Boston. Navigate to Connectivity -> Outbound Routes. For each city, click Add Outbound Route. Name the Outbound Route using the city name, e.g. Dallas. Change the Time Zone, if required. For the Trunk Sequence, choose the Trunk with the matching City name from the pull-down menu. Next, click the Dial Patterns tab. Here you’ll need to decide which calls you want to permit between the Headquarters office and Dallas. For the Dallas extensions, you would enter 2 in the Prefix field and NXX in the Match Pattern field. If there are 4-digit numbers on the Dallas PBX that you want to enable for callers from Atlanta, you add another Dial Pattern with the 2 Prefix and NXXX for the Match Pattern. If you want callers from Atlanta to be able to use Outbound Routes on the Dallas PBX to make PSTN calls, you would add another Dial Pattern with the 2 Prefix and NXXNXXXXXX for the Match Pattern. Similar additions could be made for international calls assuming you allow them on your Dallas PBX. Once you’ve added the desired Match Patterns, click Submit and Apply Config when prompted. Repeat these steps to add an Outbound Route for Boston, and you’re finished on the Atlanta PBX.


    Repeating the Setup Process in Other Cities

    Now simply repeat the steps above on each of your PBXs. For PJsip trunks, you’ll need to create one for every other city in your operation. And, for Outbound Routes, do the same. Once all of your PJsip trunks are activated, you can verify functionality in the Asterisk CLI with this command: pjsip show aors. Once the Status for each city displays as Avail, you can begin making test calls between the servers using a phone connected to each PBX.

    Our Favorite All-You-Can-Eat Deals in Cyberspace



    Let’s begin with a mea culpa. We’ve been wrong on a few all-you-can-eat deals over the years including the CloudAtCost switcheroo, the Google Voice fiasco, and a few other cloud provider implosions. But our overall track record has been pretty good over the past decade, and today we have some fresh deals that are worth a careful look. We, of course, would encourage everyone to perform their own due diligence and at least acknowledge the cautionary note: "If a deal sounds too good to be true, it probably is." Having said that, these are all deals that we continue to use and to rely upon as this is written.

    Free Oracle Cloud Hosting for Life


    We’ve previously written about the free Oracle Cloud hosting deal so we won’t dwell on it here other than to provide a link that will show you how to sign up and use the Oracle Cloud to host your Incredible PBX servers for life at no cost, up to four of them. Here’s the link.

    Domain Names at Cost


    There are lots of sources to acquire domain names whether you need one or dozens. But nobody comes close to matching Spaceship pricing across the board. Here are some examples: .com for $8.80/year, .org and .net for $9.80, .us for $6.48, and .uk for $5.23.

    VPN Unlimited for Life


    Whether you use a VPN for anonymous protection while surfing the web or for access to premium movie services while visiting countries that block some services, a lifetime VPN subscription is a worthy investment. In this case, waiting for the deal to come along is worth a little patience. Our favorite lifetime service is VPN Unlimited which, as recently as November 2021 was selling for $18. Today it’s $199.99. Two weeks ago it was $99. There are numerous VPN for Life services but, if you stray from VPN Unlimited, we would encourage you to sign up for a one month plan to be sure it meets your needs in terms of performance and reliability with services such as Netflix. In the alternative, make frequent visits to LowEndTalk, LowEndSpirit, and StackSocial and await the next deal. It won’t be very long.

    Unlimited Music Streaming Services


    Perhaps the greatest blessing for parents was the arrival of unlimited streaming music services which all but eliminated the risk of being sued or prosecuted for music piracy. If you have a kid in college, the best deal on the planet is Spotify’s 4-year, $4.99 a month plan which provides access to their entire music catalog as well as a Hulu subscription. While you only get one stream at a time, lucky parents will soon discover that their listening hours rarely conflict with the waking hours of college students.

    For Amazon Prime subscribers, Amazon has recently sweetened their music deal with Amazon Music Prime which provides free streaming access to 100 million songs. You can build playlists and so long as you stream them in Shuffle mode, Amazon will play all of your playlist selections before injecting any other content. Quite a deal.

    Unlimited Home Internet Service



    If you’ve grown weary of Comcast, Spectrum, and WOW regularly moving their pricing goalposts, you’ll be pleased to learn that both T-Mobile and Verizon now offer Home Internet Service with no data caps. We actually use T-Mobile’s offering in two locations so the first costs $30 a month with a Magenta Max cell plan and the second costs $50 a month, still a deal compared to the cable companies. Even in remote areas, we’ve found the download speeds to be quite reasonable at 200+ Mbps. And, with T-Mobile, the price is guaranteed for life. With Verizon and a qualifying cell plan, the monthly cost is $25 a month with a 2-year price guarantee. Both will partially cover early termination fees from your previous cable provider.

    Lifetime Cloud Storage Services


    We would be the first to warn you that lifetime cloud offerings can be a slippery slope simply because the provider’s monthly costs never go down. So long as their subscription model provides more revenue than their cost of doing business, they will probably stay around. Once the math changes, your investment AND your data goes down the toilet along with the provider. Having said that, we’ve signed up with pCloud which has been in business for a decade and boasts a subscriber base of 16 million users. Their lifetime 2TB Individual Plan provides 2TB of storage and 2TB of monthly download bandwidth for $399. Their 500GB Individual Plan provides 500GB of storage with 500GB of monthly download bandwidth for $199. Both plans include a PUBLIC folder (ours is here) in which you can store files with download links that are accessible anonymously using web browsers, wget, and curl. All of their monthly and lifetime plans include a 10-day money-back guarantee. Rave reviews are available from numerous sources using a Google search for pcloud reviews.

    On the other end of the usability spectrum is the first provider we tried, Internxt. We bought their 1TB lifetime offering for €99.00, and it’s no longer available. Instead, they now offer a 2TB lifetime plan for $299 or a 5TB plan for $499. The gotcha with Internxt is their crippled download service. It only supports downloads using a web browser. Wget and curl downloads all fail with their support staff professing surprise or ignoring support requests. Steer clear!

    Lifetime Email Hosting for BYO Domains


    Email hosting is something that most of us take for granted, either because we have a free service from Google or Microsoft or because our Internet provider provides "free" email accounts. The old adage that you’re being penny-wise and pound-foolish seems particularly appropriate here. Your email service is a key critical component particularly if you’re in business. Our solution and the one we recommend is the MXroute Lifetime Plan for $199. With it, you can host unlimited domains and unlimited email accounts with a storage limit of 10GB and 300 outbound emails per hour. They have awesome tutorials to help you get started.

    The Beauty of Incredible PBX: ClearlyIP Module Management



    When Incredible PBX was released, you may recall that we jettisoned reliance on FreePBX® repositories and adopted Clearly IP’s far superior repository setup for FreePBX module management. Most of you have never noticed… until today. As lady luck would have it, Sangoma recently released a buggy version of the User Control Panel (UCP) module which literally blows up when you next attempt to access UCP.

    One of the hidden beauties of Incredible PBX is that we now have version control over FreePBX modules thanks to Clearly IP’s Mirror Administration application. What this means is we can restrict which versions of every FreePBX module get installed on every Incredible PBX server. So when a problem such as the UCP bug causes a serious operational issue for our users, we can simply use Mirror Admin to back rev the UCP module to a working release, version 16.0.36 in this case.

    The other hidden advantage of Incredible PBX is we maintain dozens of honeypot servers around the world running many different versions of Linux, Asterisk, and FreePBX. So, when this issue popped up, it was a simple matter to visit various sites until we found one using a functional version of the User Control Panel. Then a simple tweak of the default UCP version in Mirror Admin meant administrators could quickly restore UCP functionality. Here’s how.

    Begin by logging into the FreePBX GUI with your admin credentials. Navigate to Module Administration and choose the Check Online option. Scroll down to the User Control Panel module and choose Force Download and Downgrade. Click the Process button to migrate back to UCP 16.0.36, and you’re back in business. Enjoy… and tell your friends!

    The Ambidextrous Laptop: A Perfect Fit for Asterisk and VoIP



    Until we bought a 15-inch Windows laptop with 20 gigs of RAM and a 1 terabyte NVMe SSD for under $500, we never would have considered such a computer an ideal virtual machine platform. And, to our surprise, with Windows 11 and a 4-core Ryzen 3 processor, it not only ran VirtualBox flawlessly, but Microsoft’s Windows Subsystem for Linux (WSLg) also performed admirably.
     


    And then we tried out the UTM virtual machine platform on one of Apple’s new MacBook Air machines with an M1 processor and 16 gigs of RAM. Wow! How the world has changed. The MacBook Air 1TB offering buys you triple the performance of the Ryzen machine. But it’s more than triple the cost. So our message for today is don’t underestimate the benefits of running Asterisk® in a virtual machine environment where flawless backups are only the click of a button away. And, yes, it can travel with you without missing a beat. Add a free softphone such as Zoiper 5, and you have an instant mobile office. Of course, if your primary use is commercial, you’ll need to pay for Zoiper 5 Pro. The $50 price tag won’t break the bank.

    What’s our favorite platform? You can probably guess. But, to be honest, the Ryzen-based Windows 11 machine is a steal and performs more than adequately as a virtual machine platform. And, if you’re more comfortable in the Windows ecosystem, it’s a smart choice. LibreOffice is available at no cost on both the Windows and Mac platforms as is Zoiper. So, functionally, as a travel companion and as a robust virtual machine host, you can’t lose.

    While we’re on the mobile computing topic, we would be remiss in not addressing the topic of security. If you travel and are away from the protections of your home or office firewall, we will restate the obvious. You still need firewall protection for your computer. This is especially true if you’re also using the machine to host a PBX capable of making worldwide VoIP calls. While Windows and Mac platforms as well as Incredible PBX® all offer software-based firewalls, we still consider a hardware-based firewall a prudent addition. It’s your phone bill.



    So here’s our tip of the week for a gadget to slip into your travel bag. Never leave home without it! It’s the GL.iNet Mini Travel Wireless Pocket Router currently available on Amazon for $32. You can plug it into your PC or a USB power source and set up a private WiFi network in minutes whether you’re in a hotel or any other location with public WiFi access. For those that always rely upon virtual private networks for communications as we do, this little router has OpenVPN support built in.

    Full Disclosure: As an Amazon Associate, Nerd Vittles earns commissions from qualifying Amazon purchases to keep the Nerd Vittles lights burning brightly. And, as has always been the case, Nerd Vittles eats its own dog food. Simply stated, we always use and test products before recommending them to others.

    Happy New Year: It’s Incredible PBX 2027 for the Raspberry Pi



    Ever since Eben and Liz Upton first introduced the Raspberry Pi to our Charleston community over a decade ago, the primary focus of their development team has been to encourage people of the world to learn about computers on an affordable platform. To this day, the Raspberry Pi 4B can still be purchased (if you can find one) for $35. Unfortunately, supply chain issues have taken their toll. If you prefer not to pay a premium for the Raspberry Pi 4B or 400 keyboard, then visit the RPiLocator. If time is of the essence, then eBay is your friend for both the RasPi4 and the RasPi 400 keyboard.

    Many of you may know that Mark Spencer, who founded Digium and initially developed Asterisk®, now has a new avionics company in Huntsville, Avilution. You may be surprised to learn that their unPanel Avionics platform was developed using redundant Raspberry Pi’s.

    UPDATE: Download the latest Incredible PBX 2027 image for RasPi here.

    To celebrate the New Year, we’ve taken an entirely new approach in developing this latest Incredible PBX iteration for the Raspberry Pi. In previous builds, we’ve offered a turnkey image for the Raspberry Pi. This time around we’ve incorporated the same Debian 11 installer that we use on AMD64 and ARM64 platforms. The primary advantage is that this installer will continue to work with future Raspberry Pi hardware that supports the Debian 11 platform. It also allows us to make slipstream enhancements across all hardware platforms in minutes instead of weeks. One final benefit of the new design is that you now can take advantage of the Raspberry Pi Imager which lets you create the base Debian 11 microSD platform for the Raspberry Pi in minutes.

    What’s Included? Incredible PBX 2027 serves up a never before available VoIP powerhouse featuring Asterisk 20 and all FreePBX 16 GPL modules, an Apache web server, the latest MariaDB SQL server (formerly MySQL), SendMail mail server, Webmin, and most of the Incredible PBX feature set including SIP, PJSIP, SMS, voice recognition, AsteriDex, gTTS Text-to-Speech VoIP applications, Call-By-Name Dialing, News, Weather, Telephone Reminders, and hundreds of features that typically are found in commercial PBXs: Conferencing, IVRs and Email Delivery of transcribed voicemails, AutoAttendants, 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 our VoIP providers and start making and receiving calls instantly. Or you can use the new ClearlyIP trunking module included in the GUI for seamless integration of SMS messaging into FreePBX® and its User Control Panel.

    Choosing a SIP Provider. As we mentioned, Incredible PBX 2027 comes preconfigured to support many of the major SIP providers including those that financially support Nerd Vittles and our open source projects: ClearlyIP, Skyetel, and VoIP.ms. As the old saying goes, they may not be the cheapest, but you get what you pay for. With all our providers, you only pay for minutes you use so signing up with more than one provider is a smart idea. For the full list of supported VoIP providers, visit the Incredible PBX Wiki.

    Assembling the Required Raspberry Pi Components

    Before you can deploy Incredible PBX 2027, you’ll first need the necessary Raspberry Pi hardware. To support the enhanced Incredible PBX 2027 platform, we strongly recommend either the Raspberry Pi 400 or the Raspberry Pi 4B with at least 2GB RAM. You can choose a reseller below for quicker delivery. Assuming you already own an HDMI-compatible monitor and a USB keyboard (only required if you don’t buy a RasPi 400)…

  • Raspberry Pi 4B or Raspberry Pi 400
  • $10 USB-C RasPi 4 (only) Power Supply
  • $9 32GB microSDHC Class 10 card (strongly recommended!)
  • $5 Official RasPi 4B Case or see above for our favorite
  • Getting Started with Incredible PBX 2027

    Begin by downloading Raspberry Pi Imager for PC, MAC, or Ubuntu desktop. Run the Imager from your desktop computer with the following settings after inserting microSD card in your desktop machine:

    OS: Raspberry Pi OS (other) -> Raspberry Pi OS Lite (64-bit)
    Storage: Select your microSD card (32GB Type 10 recommended)
    Click WRITE
    

    Remove the microSD card from your desktop computer. Insert it into your Raspberry Pi and power on the device. The initial Raspberry Pi OS setup for the United States follows. For users elsewhere, follow your nose.

    Choose keyboard layout: (Other, English (US) for USA users)
    Keyboard Layout: English (US)
    username: nerd
    password: make it secure, type it twice
    login: nerd with new password
    sudo passwd root
    create new secure root password
    logout: exit
    login: root with new root password
    userdel nerd
    nano -w /etc/ssh/sshd_config
      edit and uncomment: PermitRootLogin yes
      uncomment PasswordAuthentication yes
      save: Ctrl-X, Y, then ENTER key
    run: raspi-config
      Settings Apply to: pi
      Localization: WLAN Country: US
      System Options: Wireless LAN: Enter your SSID and SSID passphrase
      System Options: Hostname: debian
      System Options: Power LED: YES
      Interface Options: SSH: YES
      Localization: Locale: Disable en_GB.UTF-8 and Enable en_US.UTF-8
      Localization: TimeZone: America, NewYork
      FINISH and Reboot
    

    Once your Raspberry Pi has restarted, login as root with your root password and issue the following commands:

    wget http://incrediblepbx.com/IncrediblePBX2027-D-RasPi.sh
    chmod +x IncrediblePBX2027-D-RasPi.sh
    ip a
    

    To assure that your desktop computer is whitelisted in the Incredible PBX firewall, we recommend completing the rest of the install using SSH or Putty on your desktop machine. The ip a command above will tell you the local IP address of your RasPi. So login using this command: ssh root@ip-address. Then issue the following command:

    ./IncrediblePBX2027-D-RasPi.sh
    

    When the install finishes, reboot your Raspberry Pi and log back in as root. Let the Automatic Update Utility bring your system up to current specs after which the pbxstatus display should show something like the following.

    NOTE: To activate an OpenVPN client connection, create and copy a client configuration named incrediblepbx2027.ovpn from your OpenVPN server into the /etc folder & reboot.


    First Boot of Incredible PBX 2027

    If you entered WiFi credentials when running raspi-config above and your Raspberry Pi does not have a wired network connection, it should automatically enable the Wi-Fi connection on reboot. Issuing the command ip a will tell you the local IP addresses of wlan0 and eth0. With the Raspberry Pi 3B, 4B and 400, WiFi is built into the hardware. But you still have to provide your SSID name and SSID password to make a connection to your WiFi network. If pbxstatus does not show a network connection, here’s how to enable Wi-Fi:

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

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

     

    Now restart your server: reboot. When the reboot finishes, you now should have network connectivity.

    You may also need to change the default PortKnocker setting to your wireless LAN connection:

    sed -i 's|eth0|wlan0|' /etc/default/knockd
    service knockd restart
    

     

    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 RasPi. This is required for all of the SIP providers included in the Incredible PBX 2027 build. Otherwise, all inbound calls will fail.

    Configuring Skyetel for Incredible PBX 2027

    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. Effective 10/1/2023, $25/month minimum spend required.

    Skyetel typically does not require 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 2027:

    • Name: MyPBX
    • Priority: 1
    • IP Address: PBX-Public-IP-Address
    • Port: 5061
    • Protocol: UDP
    • Description: 2027.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 2027

    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 2027 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. On the Incredible PBX side, simply Enable the VoIPms trunk and save your update.

    Adding a Bootable SSD to Raspberry Pi

    Shown below are the two components that make up the 256GB storage solution for the Raspberry Pi. These include the M.2 SSD SATA drive and the M.2 enclosure which provides a USB connector that’s compatible with your RasPi. Assembly of the components takes less than a minute as shown in the steps below:




    You can order the M.2 SSD SATA drive and the M.2 enclosure using our Amazon referral links which help support Nerd Vittles and the Incredible PBX open source project.

    Once you have assembled your SSD in the sleeve, log back in as root using SSH or Putty. For best performance, insert the SSD drive into one of the blue USB 3.0 ports and verify that /dev/sda device is shown when you issue the command: fdisk -l

    Now proceed with the following steps to copy the image from your microSD card to the new SSD SATA drive:

    rpi-clone -l -e sda -f sda
    # answer prompts with yes and incred2027
    # once the image is copied, dismount the drive when prompted
    mount /dev/sda2 /mnt/clone
    cd /mnt/clone/boot
    cp -p -r /boot/* .
    sed -i 's|sda2|mmcblk0p2|' /boot/cmdline.txt
    cd /
    umount /mnt/clone
    halt
    

     
    Now you’re ready to restart your Raspberry Pi from the SSD SATA drive. Remove the microSD card and reboot your server.



    Configuring a Softphone for Incredible PBX 2027

    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. 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 or the Mac App Store. 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.

    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.

    Last but not least, we also like the Zoiper5 free softphone. You can download it for your Windows, Mac, and Linux desktops here.

    Audio Issues with Incredible PBX 2027

    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 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. IMPORTANT: You MUST use a Gmail App Password instead of your Gmail account password.

    /root/enable-gmail-smarthost-for-sendmail
    

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

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

    Incredible PBX 2027 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.

    add-fqdn is used to whitelist a fully-qualified domain name in the firewall. Because Incredible PBX 2027 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.

    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.

    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.


    rpi-clone is a utility that makes it easy to make a bootable image of the microSD card used to start your Raspberry Pi. You’ll need a USB-to-microSD adapter to begin. Insert a backup microSD card large enough to hold all of the data on the primary microSD card (df -h). Insert the USB stick with the card. Identify the backup microSD card, usually sda (fdisk -l). Format the backup microSD card: mkfs.vfat /dev/sda1 && mkfs.ext4 /dev/sda2. Then issue the following command to clone the primary microSD card: rpi-clone -f sda. Tutorial here.

    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 2027 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 2027. 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.

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

    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 2027.

    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"

    Keeping FreePBX 16 Modules Current

    We strongly recommend that you periodically update all of your FreePBX modules to eliminate bugs and to reduce security vulnerabilities. Make a backup image with rpi-clone first! From the Linux CLI, log into your server as root and issue the following commands:

    rm -f /tmp/*
    fwconsole ma upgradeall
    fwconsole reload
    /root/sig-fix
    systemctl restart apache2
    /root/sig-fix
    

    Resolving an Expired Certificate Alert

    1. Navigate to Admin -> Certificate Management in the FreePBX GUI
    2. Click the Trashcan to delete the Self-Signed Certificate
    3. Click New Certificate -> Generate Self-Signed Certificate
    4. In the Description field, type: Default
    5. Click Generate Certificate button

    What About Fax Support?

    Come back next week for a pleasant surprise.

    Tired of Waiting on Hold? Here’s a Simple Asterisk Fix



    We’ve all placed calls to support lines that keep you waiting on hold for what seems like an eternity. While some companies now offer a call back service that holds your place in the queue, many still do not. One of our users recently asked whether there was a simple way with Asterisk® to preserve your place in line without tying up your phone waiting for the other party to finally pick up the call. Here’s what we came up with.

    The idea here is to use Unattended Transfer to transfer your end of the call to an extension that plays a message to dial zero to be reconnected with the calling party once your turn in the call queue finally arrives. To send your call to Pseudo-Hold, dial ##4653# (4653 spells HOLD). On Incredible PBX platforms, this will initiate an unattended transfer of your call and free up your phone.

    Now we only need a little Asterisk dialplan code plus a recorded message telling the other party to press 0 to be immediately reconnected with us when they come on the phone. When the other party presses 0, the dialplan will transfer the call back to the extension that transferred the call to what we are referring to as Pseudo-Hold.

    To begin, navigate to the custom folder in either /var/lib/asterisk/sounds/custom or /var/lib/asterisk/sounds/en/custom depending upon your version of Asterisk. Now download and install both the recording and the dialplan snippet:

    wget http://incrediblepbx.com/presszero.tar.gz
    tar zxvf presszero.tar.gz
    rm -f presszero.tar.gz
    sed -i '\:// BEGIN Zero:,\:// END Zero:d' /etc/asterisk/extensions_custom.conf
    sed -i '/\[from-internal-custom\]/r dialplan.txt' /etc/asterisk/extensions_custom.conf
    rm -f dialplan.txt
    asterisk -rx "dialplan reload"
    

    For those that are curious, the dialplan.txt snippet looks like this:

    ;# // BEGIN Zero Reconnect
    exten => 4653,1,Answer
    exten => 4653,2,NoOp(Dialed Peer Number: ${DIALEDPEERNUMBER})
    exten => 4653,3,Background(custom/PressZeroToReconnect)
    exten => 4653,4,WaitExten(2)
    exten => 0,1,Background(connecting)
    exten => 0,2,Dial(SIP/${DIALEDPEERNUMBER})
    exten => t,1,Goto(4653,3)
    exten => i,1,Goto(4653,3)
    exten => h,1,Hangup
    ;# // END Zero Reconnect
    

    To walk you through how it works, here we go. When you press ##4653#, the call is transferred to the 4653 extension shown above. In line 1, it answers the call. In line 2, it deciphers the extension from which the call was transferred. In line 3, we play the Press Zero to Reconnect message. In step 4, we wait for the other party to press 0. If they don’t within 2 seconds, we loop back up to line 3 and play the message over and over again. If the other party presses zero, we drop down to 0,1 which plays a message saying "Connecting." Then 0,2 sends the call back to the extension that originally transferred the call to 4653.

    Sangoma Beefs Up FreePBX Security… For a Price



    We’ve lost count of the number of FreePBX® security breaches that were directly attributable to vulnerabilities in the FreePBX web interface. Suffice it to say, it was the reason that PBX in a Flash and Incredible PBX instituted the Travelin’ Man 3 firewall a decade ago hiding the FreePBX GUI from everyone except those on a whitelist controlled by the PBX administrator.

    More than a decade later, Sangoma® finally introduces Multi-Factor Authentication (MFA) with two major gotchas. First, you have to pay for it. And second, it’s only available using Sangoma’s proprietary FreePBX platform rather than the open source release. There are so many things wrong with this greedy approach that we really don’t know where to begin.

    For openers, offering a commercial MFA solution for a supposedly open source product is fundamentally wrong. Think of it this way. You only offer a safe version of your free product if users pay for it. Next, it demonstrates a fundamental misunderstanding of why two-factor authentication (2FA) and MFA have become ubiquitous. These tools provide an extra layer of security where users have no control over the underlying code of the application. For example, you don’t own PayPal or your bank’s platform so 2FA and MFA provide an extra layer of security for customers attempting to log into their accounts, to prove they are who they say they are using a previously registered cellphone or email account.

    Contrast this scenario to those deploying FreePBX who have complete control of the underlying operating system and the FreePBX code itself. MFA doesn’t keep a disgruntled employee from gaining access to a server using an administrator password. MFA also provides zero protection against the myriad of security holes for which FreePBX has become infamous. In short, 2FA and MFA have a single task: allowing users to prove who they say they are by confirming their identity through an external source they control.

    We believe Incredible PBX has always offered a better security solution for those that control their own PBX platforms. First, the Travelin’ Man 3 firewall lets you define exactly who can see your FreePBX GUI on the public Internet. If a user isn’t in the TM3 whitelist, they not only can’t login to the FreePBX GUI, they can’t even see it. Second, for the truly paranoid, you can add a third layer of security to the TM3 firewall and FreePBX authentication. Apache offers an additional login threshold for those seeking web access to any application over which the administrator has control. With Incredible PBX, it’s as simple as adding an additional freepbx.conf file in /etc/pbx/httpdconf and restarting Apache:

    #Password protect /var/www/html/admin
    <directory /var/www/html/admin>
    AuthType Basic
    AuthName "Restricted Area"
    AuthUserFile /etc/pbx/wwwpasswd
    Require valid-user
    </directory>
    

    An administrator then has control over server access with three layers of security: (1) TM3 firewall access using the add-ip and add-fqdn scripts in /root, (2) Apache access using the apache-pw-change script, and (3) FreePBX GUI access using the admin-pw-change script.

    We believe this three-tier, administrator-managed security model offers better and safer protection not only for every user of the FreePBX platform but also for the platform itself. Most importantly, it is and always has been FREE! Start by choosing an Incredible PBX platform that best meets your requirements by visiting the Incredible PBX Wiki.
