The Most Versatile VoIP Provider: FREE PORTING

The 5-Minute PBX in the Cloud Platform for $2 a Month

If $2.10 a month for a state-of-the-art VoIP PBX isn’t too rich for your blood, then today’s your lucky day. What that buys you is a turnkey, cloud-based PBX platform that is fully installed and configured IN LESS THAN 5 MINUTES! Did we mention the feature set? The Incredible PBX 2027-U image at CrownCloud has an unequaled feature set: Ubuntu 22.04 LTS, Asterisk® 20, and FreePBX® 16 with preconfigured extensions and trunks for dozens of VoIP providers plus voicemail with transcription and email delivery, IVRs, DISA, SMS messaging, conferencing, call queues, paging, intercom, and lots of text-to-speech features to whet your developer appetite: news headlines, weather reports by zip code, today in history, and sample ODBC apps for customer and accounting lookups using MySQL/MariaDB databases. The web server offerings include the latest FreePBX GUI with all of its GPL modules plus WebMin, AsteriDex, and Telephone Reminders. It’s taken us more than a decade to develop this free platform. You get to take advantage of it in less than 5 minutes.

So what’s the difference in today’s $2 a month offering from CrownCloud and the previous offering from RackNerd for $1 a month. The major difference is Incredible PBX 2027-U is an actual image offering at CrownCloud while, at RackNerd, you had to first install the operating system and then go through the entire setup procedure for the Incredible PBX platform of your choice. The CrownCloud scenario takes five minutes while the RackNerd procedure consumes more than an hour assuming all of the repositories upon which Incredible PBX relies are on line and functioning as advertised. What you’ll quickly learn with open source software is this. We rely upon the work product of over 1,000 different individuals and companies, any one of whom can seriously break things either because their software is off-line or because they’ve "improved" something in a way that quickly cascades into a disaster for those of us that relied upon their old way of doing things. If patience and time are your strong suits, then the $1 a month alternative may be a perfect fit. Otherwise, our new CrownCloud image of Incredible PBX 2027-U is a godsend. So let’s get started.

Getting Started at CrownCloud

These 5-minute turnkey installs of Incredible PBX 2027-U for Ubuntu 22.04 are offered at the jaw-dropping price of $25 a year. The monthly cost is cheaper than a cup of coffee at Starbucks, and you’ll have a fully-functioning, production-ready KVM platform including a free snapshot with 1GB RAM, 20GB SSD storage, and 1TB of monthly bandwidth in your choice of server locations including Los Angeles, Miami, and Atlanta in the United States as well as Germany and the Netherlands in Europe. And, unlike all of the other Asterisk® aggregations, Incredible PBX still provides a source code-based platform that can be tailored to meet any special requirements your organization may need.

It’s worth mentioning that we don’t make a nickel on these cloud offerings so consider this our special thanks to all of our loyal fans.

Here are the links to sign up for the service and take advantage of the Incredible PBX 2027 deal:

After you sign up for the service, open the CrownPanel application and choose Incredible PBX 2027-U under Application Images for your base install. Take a 5-minute coffee break while your server image is installed. Once your server comes on line, login as root from a desktop machine using the password that was provided. Be sure to use SSH and NOT the VNC utility included in CrownPanel. This will assure that your desktop machine’s IP address gets whitelisted in the Incredible PBX firewall. Otherwise, you won’t be able to SSH into your server from your desktop. Once you login, the Incredible PBX configurator will prompt you to set passwords for root login, admin login to FreePBX, and admin login credentials for Apache to access AsteriDex and Reminders. Add a trunk provider (Skyetel is preconfigured and enabled by default) and a softphone or Incredible PBX SIP phone, and your PBX is ready to go.

Planning Ahead for That Rainy Day

One of our favorite features of Crown Cloud is the free snapshot (a.k.a. backup) that’s provided at no additional charge. We recommend you take snapshots regularly as you make major changes in your server’s configuration. In this way, if something comes unglued, you can easily restore the snapshot and never miss a beat. You’ll find the Remote Snapshot option in your CrownPanel menu.

Next Steps with Incredible PBX 2027

Before you can manage your PBX through a web browser, you first will need to set the root password for Ubuntu as well as the admin passwords for FreePBX and Apache web apps such as Reminders and AsteriDex. These all can be set by logging into your server as root and issuing the following commands: passwd, admin-pw-change, and apache-pw-change.

Outbound mail functionality needs to be working so that you can receive voicemail messages and faxes by email. To prevent SPAM, most ISPs and ITSPs block messages from downstream mail servers. That would be you. The easiest way to resolve this is to configure SendMail using Gmail as an SMTP Smarthost. You obviously need a Gmail account to implement this and you also will need to obtain an App password for your Gmail account, and use that in lieu of your regular Gmail password when configuring SendMail. With your Gmail username and App password in hand, log into your server as root and run: /root/enable-gmail-smarthost-for-sendmail.

If your Incredible PBX 2027 is hosted with a cloud provider, be advised that many providers do not include a swap file as part of their offering. FreePBX requires a swap file. To see if you have one, issue the command: free -h. To add one, issue this command after logging into your server as root: /root/create-swapfile-DO.

To correctly set the time on your PBX, run: /root/timezone-setup.

By default, the voicemail password for each of the configured extensions (701-705) is set to the extension number. This means the user will be prompted to set a voicemail password on the first login to voicemail for each extension. A phone must be registered to the actual extension to access its voicemail account. For example, once a phone is registered to extension 701, the voicemail setup can be accessed by dialing *98701.

Overview of the Initial Asterisk Setup Process

For those new to PBXs, here’s a two paragraph summary of how Voice over IP (VoIP) works. Phones connected to your PBX are registered with Extensions so that they can make and receive calls. When a PBX user picks up a phone and dials a number, an Outbound Route tells the PBX which Trunk to use to place the call based upon established dialing rules. Unless the dialed number is a local extension, a Trunk registered with some service provider accepts the call, and the PBX sends the call to that provider. The provider then routes the call to its destination where the recipient’s phone rings to announce the incoming call. When the recipient picks up the phone, the conversation begins.

Looking at things from the other end, when a caller somewhere in the world wishes to reach you, the caller picks up a telephone and dials a number known as a DID that is assigned to you by a provider with whom you have established service. When the provider receives the call to your DID, it routes the call to your PBX based upon destination information you established with the provider. Your PBX receives the call with information identifying the DID of the call as well as the CallerID name and number of the caller. An Inbound Route on your PBX then determines where to send the call based upon that DID and CallerID information. Typically, a call is routed to an Extension, a group of Extensions known as a Ring Group, or an IVR or AutoAttendant giving the caller choices on routing the call to the desired destination. Once the call is routed to an Extension, the PBX rings the phone registered to that Extension. When you pick up the phone, the conversation begins.

Configuring Trunks with Incredible PBX GUI

Perhaps the most difficult component to configure in the PBX is the Trunk. Almost every provider has a different way of doing things. We’ve taken some of the torture out of the exercise by providing a script which will configure settings for dozens of providers in seconds. Once installed, all you need to do is edit the desired Trunk (Connectivity:Trunks), change the Disable Trunk entry to No, and insert your credentials in both the PEER Details and Registration string of the SIP Settings Outgoing and Incoming tabs. Skyetel is enabled by default and needs no setup on the PBX side.

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 specials. 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 satisfied with the service, fund your account as desired, and Skyetel will match your deposit of up to $250 simply by opening another ticket. That gets you up to $500 of half-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 2027:

  • Name: MyPBX
  • Priority: 1
  • IP Address: PBX-Public-IP-Address
  • Port: 5060
  • Protocol: UDP
  • Description: my.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 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. In the Incredible PBX GUI, be sure to enable the VoIP.ms trunk.

Configuring V1VoIP for Incredible PBX 2027

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. In the Incredible PBX GUI, be sure to enable all of the V1VoIP trunks.

Configuring Anveo Direct for Incredible PBX 2027

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. Enable the Trunk. Then click on the custom-Settings tab and replace anveo-pin with your actual Dialing Prefix. Click Submit and Apply Config to complete the setup. In the Incredible PBX GUI, be sure to enable all of the remaining Anveo trunks.

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 Extensions with Incredible PBX GUI

Extensions are created using the Incredible PBX GUI: Applications:Extensions. Many SIP phones expect extensions to communicate on UDP port 5060. If this is the case with your SIP phone or softphone, then always create Chan_SIP extensions which communicate on UDP 5060. If your SIP phone or softphone provide port flexibility, then you have a choice in the type of SIP extension to create: Chan_SIP or the more versatile PJSIP (UDP 5061). Just remember to always configure SIP extensions with NAT Mode=YES in the Advanced tab. If your VoIP phones or softphones support IAX connectivity, you may wish to consider IAX extensions which avoid NAT problems.

When you create a new Extension, a new entry is automatically created in the PBX Internal Directory. If you wish to allow individual users to manage their extensions or use the WebRTC softphone, then you will also have to create a (very) secure password for User Control Panel (UCP) access. Choose Admin:User Management and click on the key icon of the desired extension to assign a password for UCP and WebRTC access.

Configuring a Desktop Softphone for Incredible PBX

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 a 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.


The easiest way to get started is to download a free softphone onto your desktop. We recommend Zoiper 5 for personal use. You can download and install it from here. Once installed, you’ll first need to decipher your extension password for an extension you wish to use to connect to Zoiper. Log into your Linux CLI and switch to the root user as documented above. Then run: /root/show-passwords. Specify 701 and 705 as the starting and ending extensions. Make note of the 701 extension password. Run pbxstatus and make note of your LAN IP address, e.g. 179.xx.yy.zz. Next, start up Zoiper from your desktop and choose the free version. For the desired account enter: 701@179.xx.yy.zz:5061 where 179.xx.yy.zz is the local IP address of your virtual machine. For the password, enter the 701 extension password you deciphered above. Press ENTER twice to complete the connection. When the dialer appears, try out some of the free Incredible PBX applications below.

NOTE: You must use the Keypad option shown in the right window of Zoiper after your call is connected for any app that prompts for keyboard input.

Here are some numbers to try:

123 - Reminders
222 - Timeclock for Employees (try 12345)
223 - AsteriDex Lookup & Dialer (try 335 for Delta Airlines)
947 - Weather by ZIP Code (requires keyboard entry of 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.

Configuring a Softphone Extension on a Smartphone

Adding an Incredible PBX extension to your smartphone gets a little trickier. Whether you’re an iPhone or Android lover, all smartphones use batteries, and you don’t want to drain your battery by running a softphone as a foreground app all the time. Fortunately, you now have some choices in softphones engineered to work without draining your battery. While they all cost money, it’s not much money. We’ve written about all the choices, and you’ll find the links in our Softphone Provider Recommendations on the new Incredible PBX Wiki.

With PJsip extensions, you’re not limited to a single phone connection at a time, and we’ve preconfigured extension 701 to support ten simultaneous connections. The setup on the softphone side is simple. For the server, enter the actual IP address of your PBX in the following format: 22.33.44.55:5061. Then enter 701 for the username and enter the password assigned to the 701 extension on your PBX. When an incoming call arrives, all the phones registered to extension 701 will ring simultaneously. Simply answer the call on the phone that is most convenient. For extension 702, you can change the number of simultaneous connections by clicking the Advanced tab and setting the number in Max Contacts.

Configuring Outbound Routes in Incredible PBX GUI

Outbound Routes serve a couple of purposes. First, they assure that calls placed by users of your PBX are routed out through an appropriate trunk to reach their destination in the least costly manner. Second, they serve as a security mechanism by either blocking or restricting certain calls by requiring a PIN to complete the calls. Never authorize recurring charges on credit cards registered with your VoIP providers and, if possible, place pricing limits on calls with your providers. If a bad guy were to break into your PBX, you don’t want to give the intruder a blank check to make unauthorized calls. And you certainly don’t want to join the $100,000 Phone Bill Club.

To create outbound routes in the Incredible PBX GUI, navigate to Connectivity:Outbound Routes and click Add Outbound Route. In the Route Settings tab, give the Outbound Route a name and choose one or more trunks to use for the outbound calls. In the Dial Patterns tab, specify the dial strings that must be matched to use this Outbound Route. NXXNXXXXXX would require only 10-digit numbers with the first and fourth digits being a number between 2 and 9. Note that Outbound Routes are searched from the top entry to the bottom until there is a match. Make certain that you order your routes correctly and then place test calls watching the Asterisk CLI to make sure the calls are routed as you intended.

Configuring Inbound Routes in Incredible PBX GUI

Inbound Routes, as the name implies, are used to direct incoming calls to a specific destination. That destination could be an extension, a ring group, an IVR or AutoAttendant, or even a conference or DISA extension to place outbound calls (hopefully with a very secure password). Inbound Routes can be identified by DID, CallerID number, or both. To create Inbound Routes, choose Connectivity:Inbound Routes and then click Add Inbound Route. Provide at least a Description for the route, a DID to be matched, and the Destination for the incoming calls that match. If you only want certain callers to be able to reach certain extensions, add a CallerID number to your matching criteria. You can add Call Recording and CallerID CNAM Lookups under the Other tab.

Audio Issues with Incredible PBX 2027

While it is always a good idea anyway, if you experience one-way or no audio on some calls, be sure to 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.

Adding Fax Support to Incredible PBX 2027

We’ve had to live without faxing on the new Incredible PBX 2027 platforms since the beginning of the year. But those days are over. If you’d like to add fax support to your virtual machine, head over to our new Fax Tutorial to install the components. It only takes a couple minutes.

Adding Incredible PBX 2027 to an OpenVPN Network

We previously have documented the procedure for creating an OpenVPN server as well as OpenVPN client templates (.ovpn). If you need a refresher, the tutorial is here. To add your Incredible PBX 2027 server to an existing OpenVPN network, begin by creating an incrediblepbx2027.ovpn template on your OpenVPN server. Be sure to comment out or delete the setenv line in the template. Then copy this template to /etc on your Incredible PBX 2027 server. The following commands are already in place:

echo "[Unit]
Description=openvpn2027
ConditionPathExists=/etc/openvpn-start
After=rclocal.service
[Service]
Type=forking
ExecStart=/etc/openvpn-start /etc/incrediblepbx2027.ovpn
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
PermissionsStartOnly=true
SysVStartPriority=99
[Install]
WantedBy=multi-user.target" > /etc/systemd/system/openvpn2027.service

We’ve also enabled this openvpn2027.service which will start when you reboot your server. The OpenVPN IP address should now appear on the LAN line in pbxstatus:

systemctl enable openvpn2027.service
reboot

Deploying ODBC Apps with Incredible PBX 2027

Appreciating that many use a PBX to perform actual tasks for your business, we have included two sample ODBC apps to give you a head start. The code for these ODBC apps is stored in odbc.conf in the /etc/asterisk folder. Dialing 222 from any Asterisk extension calls up the TimeClock application which provides access to an employee database. You can enter 12345 as an employee number to see how it works. Dialing 223 from any Asterisk extension connects to the AsteriDex MySQL database and performs a lookup based upon the 3-digit code corresponding to the first three letters of the company name. For example, entering 335 (D-E-L) will call up the entry for Delta Airlines and connect you to their reservations desk once you have an outbound trunk enabled. You could build something similar to look up real-time inventory information from a MySQL database. These are just examples of the thousands of applications that could be quickly developed using ODBC and the Incredible PBX 2027 platform.

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.

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.

admin-pw-change is used to set the admin password for access to the FreePBX/Incredible PBX web GUI using a browser pointed to the local IP address of your server.

apache-pw-change is used to set the admin password for access to Apache/Incredible PBX apps including AsteriDex and Reminders. This provides a password layer of protection for access to these applications.

incrediblebackup2021 makes a backup of critical components on your PBX to a tarball saved in /backup. This should be copied to safe location off-site for a rainy day.

incrediblerestore2021 restores a backup file which has been copied to the /backup folder.

ipchecker is a script which deciphers the public IP addresses associated with whitelisted FQDNs created with add-fqdn on your server. If any of the addresses have changed, the firewall is restarted after updating the IP addresses. By default, it is executed every 10 minutes by /etc/crontab.

licenses.sh displays the license associated with each of the FreePBX modules on your server.

logos-b-gone removes proprietary artwork from your PBX and is no longer necessary with the included IncrediblePBX FreePBX module.

mime-construct is a command-line utility to send emails with attachments.

neorouter-login is a script to add your PBX to a NeoRouter VPN. Tutorial here.

odbc-gen.sh is a script that was run to generate the ODBC settings for Asterisk. Do NOT use it.

openvpn-start is a script to add your PBX to an existing OpenVPN network using an .ovpn config file. Tutorial here.

pbxstatus displays status of all major components of Incredible PBX 2027.

pptp-install is a script to create a PPTP network connection for your PBX. Tutorial here.

purge-cdr-cel-records removes all CDR and CEL records from the MySQL database.

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 2027 actually is. A similar listing is available in the GUI at Admin -> Feature Codes.

show-passwords is a script that displays most 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.

sig-fix disables Module Signature Checking in the FreePBX GUI. This should not be necessary unless you have added or edited FreePBX Modules with missing module signatures.

sms-skyetel is a script to send SMS messages using a Skyetel trunk.

sms-voip.ms is a script to send SMS messages using a VoIP.ms trunk.

sms-blast, sms-blaster, and sms-dictator are scripts for message blasting. Tutorial here.

timezone-setup is a script to set the timezone for your PBX.

update-IncrediblePBX is a script that runs the Automatic Update Utility whenever you login to your server as root. These updates typically resolve bugs and security issues with your PBX. Do NOT remove it.

wolfram is a script to deploy Wolfram Alpha on your PBX. Tutorial here.

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"

Implementing Call By Name with 411

Once you have an Outbound Trunk and Route configured, deploying Call by Name by dialing 411 is simple. The way it works is to pick up any phone connected to your PBX and dial 411. When prompted for the name of the person or company to call, say the name as you entered it in the AsteriDex directory, e.g. Delta Air Lines. The name will then be looked up to decipher the number of the person or company to call. Then the call will be placed using your default outbound route. To deploy Call By Name, simply follow the setup instructions in this Nerd Vittles tutorial.

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!


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. 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

Systems Integration and Public Participation with FreePBX



It’s been an interesting few days in the FreePBX® VoIP community with a thread on the VoIP-Info.org and another on the FreePBX Forum. It’s prompted us to revisit what open source development is all about and what all of this means to those of you that rely upon Asterisk® and FreePBX.

After the departure of the Schmooze folks from Sangoma, virtually all development has been moved behind closed doors with the first opportunity for public participation occurring after new features appear in modules pushed to the so-called Edge repository. This is where folks can shake the kinks out of modules that presumably are almost ready for prime time. For example, take a look at the Changelog for the Framework Module. Prior to the departure of the Schmooze team, changes were managed by openly-accessible tickets. But now you will notice tickets bear a FREEI designation indicating restricted Sangoma-internal access only.


Beta previously was an appropriate moniker for these modules. If you read the FreePBX forum post above, you’ll note that now modules are being pushed to the Edge repository not only before public comment but apparently before much of any internal testing is performed by the Sangoma folks. The net result is you’d be crazy to ever use Edge modules in any production environment where, in the past, Edge modules more typically were used to fix something that was already broken in the traditional repository. Because the Bootstrap module is the lynchpin of virtually all other FreePBX modules, a recent glitch that had not been tested broke almost everything in FreePBX 16 if you happened to be using Edge modules.

I’m reminded of the old adage about marine aquariums. You never want to put a new fish in your main tank unless you’re willing to risk killing all of your other fish. This latest fiasco prompts our cautionary note about further use of the FreePBX Edge repository. Don’t load new modules on your production servers without testing them first in a VirtualBox sandbox unless you have a snapshot or backup of your server that can be deployed in minutes when something cataclysmic occurs.

And that brings us to our response concerning what Incredible PBX® is and is not all about. Going back to the early 80’s, we began tweaking hardware and software deployments to eliminate much of the pain associated with deployment of automated systems. Our friend on the VoIP-Info forum refers to Incredible PBX as a fork of FreePBX. Quite the contrary, it is anything but a fork. We use the FreePBX GPL modules exactly as they are published by Sangoma with an additional master key not controlled by Sangoma for your protection and for ours. This allows us to block specific module updates that prove to be dangerous for our users. Equally important, Incredible PBX offers improved functionality and stability, the same features that are typically associated with the work of a systems integrator… that you pay for. On the stability side, we migrated to new FreePBX repositories maintained by Clearly IP simply because the FreePBX repos had become extremely unreliable and proprietary. Sangoma deploys modules using key signatures that only they control. That means if you make any improvements or changes the FreePBX Dashboard displays all sorts of security alerts, something your customers and end-users would prefer not to see. Some of you may recall this was our primary objection to module signatures years ago.

On the enhancement side, we’ve tried to add free components that our millions of readers have clamored for. You may recall that Nerd Vittles was the first to provide turnkey Google Voice support for Asterisk over a decade ago. We then tackled security after numerous compromises of FreePBX systems around the world. Since then the list has grown exponentially. Here’s the added feature set you’ve enjoyed by deploying an Incredible PBX platform instead of the FreePBX Distro. And, unlike FreePBX commercial modules, these components won’t cost you a dime and are freely distributable. So the choice is yours.

5 Minute Wonder: Incredible PBX 2022 in Cloud for $25/Yr.



We’ve been building turnkey Incredible PBX® servers for virtual machine platforms for many years. Because the servers are built from images, typical install times have been 5 minutes or less with Proxmox, VirtualBox, and VMware ESXi. But the missing piece has been a similar image install on a true cloud-based platform. This limitation was primarily due to the fact that we don’t own or control the available cloud platforms which typically limit image installs to operating systems such as CentOS, Debian, Ubuntu, and Windows. However, CrownCloud was good enough to add our Incredible PBX 2021 Debian image and the Incredible PBX 2020 CentOS 7 image to their portfolio. And, today, we have more good news. CrownCloud has now added the Incredible PBX 2022 image for Rocky 8 as well.

These 5-minute turnkey installs of Incredible PBX 2020 for CentOS 7, Incredible PBX 2021 for Debian 10, and now Incredible PBX 2022 for Rocky 8 are being offered at the jaw-dropping price of $25 a year. The monthly cost is cheaper than a cup of coffee at Starbucks, and you’ll have a fully-functioning, production-ready KVM platform including a free snapshot with 1GB RAM, 20GB SSD storage, and 1TB of monthly bandwidth in your choice of server locations including Los Angeles and Atlanta in the United States as well as Germany and the Netherlands in Europe. And, unlike all of the other Asterisk® aggregations, Incredible PBX still provides a source code-based platform that can be tailored to meet any special requirements your organization may need.

We don’t make a nickel on these offerings so consider this our special thanks to all of our loyal fans.

Here are the links to sign up for the service and take advantage of these Incredible PBX deals:

When you sign up for the service, choose any traditional OS for the base install. Once it’s on line, go into CrownPanel and choose Reinstall. Then select Incredible PBX 2022 for Rocky from the Application Images pulldown as your new install. In less than 5 minutes, your server will be ready for you to login. Be sure to use SSH and NOT the VNC utility included in CrownPanel. This will assure that your desktop machine’s IP address gets whitelisted in the Incredible PBX firewall. Otherwise, you won’t be able to SSH into your server from your desktop. Once you login, the Incredible PBX configurator will prompt you to set passwords for root login, admin login to FreePBX, and admin login credentials for Apache to access AsteriDex and Reminders. Add a trunk provider (Skyetel is preconfigured and enabled by default) and a softphone or Incredible PBX SIP phone, and your PBX is fully operational. Check out the CrownCloud Wiki.


Planning Ahead for That Rainy Day

One of our favorite features of Crown Cloud is the free snapshot (a.k.a. backup) at no additional charge. We recommend you take snapshots regularly as you make major changes in your server’s configuration. In this way, if something comes unglued, you can easily restore the snapshot and never miss a beat. You’ll find the Remote Snapshot option in your CrownPanel menu.

Configuring Skyetel for Incredible PBX

If you’ve decided to go with Skyetel, here’s the drill. Sign up for Skyetel service and take advantage of the Nerd Vittles specials. 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 satisfied with the service, fund your account as desired, and Skyetel will match your deposit of up to $250 simply by opening another ticket. That gets you up to $500 of half-price calling. Credit is limited to one per person/company/address/location. Effective 10/1/2023, $25/month minimum spend required.

Skyetel does not require SIP registrations to make connections to your PBX. Instead, Skyetel can use 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:

  • Name: MyPBX
  • Priority: 1
  • IP Address: PBX-Public-IP-Address
  • Port: 5060
  • Protocol: UDP
  • Description: my.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. Everything is already in place on the Incredible PBX 2022 side of the house so you can start making and receiving calls immediately.

Configuring ClearlyIP SIP Trunking

For the tightest integration with FreePBX, no SIP provider holds a candle to Incredible PBX SIP Trunking with ClearlyIP. The reason is fairly obvious. The ClearlyIP folks were the original developers of FreePBX. In addition to all of the traditional SIP trunking services, you also get CNAM support and state-of-the-art E911 service which can be deployed in full compliance with Kari’s Law and the Ray Baum Act. If you’re a system integrator and don’t know about your financial liability for failure to comply with the new rules, it’s time to do some reading.

Configuring VoIP.ms for Incredible PBX

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 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. In the Incredible PBX GUI, be sure to enable the VoIP.ms trunk.

Configuring Anveo Direct for Incredible PBX

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. Enable the Trunk. Then click on the custom-Settings tab and replace anveo-pin with your actual Dialing Prefix. Click Submit and Apply Config to complete the setup. In the Incredible PBX GUI, be sure to enable all of the remaining Anveo trunks.

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 SIP Phone for Incredible PBX 2022

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 is 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. We obviously recommend the Incredible PBX IP phones from ClearlyIP which are the most versatile.

If you’ve been keeping up with recent Nerd Vittles developments, then you already know that we have just introduced a new Cellular Phone which connects directly to your PBX and serves as a perfect remote extension and traveling companion. You can read all about it here.

Software devices such as the YateClient softphone are another option for desktop machines. 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 YateClient for Windows 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 plus :5061 for the PJsip 701 extension, 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. For Android users, check out the terrific new VitalPBX Communicator. Works flawlessly with Incredible PBX.

For smartphone solutions, visit the Incredible PBX Wiki for our softphone recommendations.

Configuring SendMail with Incredible PBX

In order to receive voicemails by email delivery, outbound mail functionality from your server obviously is required. We strongly recommend configuring SendMail using either your ISP or Gmail as an SMTP Relay Host. 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. You also must enable Less Secure Apps access to the Gmail account.

Configuring a Gmail account with Incredible PBX 2022 is as simple as entering your Gmail credentials. Just run this script: /root/enable-gmail-smarthost-for-sendmail.

Here are the steps using a Gmail account with Incredible PBX 2020:

cd /etc/mail
yum -y install sendmail-cf
hostname -f > genericsdomain
touch genericstable
cd /usr/bin
rm -f makemap
ln -s ../sbin/makemap.sendmail makemap
cd /etc/mail
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 OR
#  use your Gmail App Key if 2-step verification is enabled
# 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

Even though these servers are hosted in the cloud, we still recommend using a SmartHost to minimize email delivery problems.

Test outbound mail using this command with your actual email address:

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

On some implementations, you may notice in the FreePBX GUI that the mail queue has failed. Here's the fix:

chmod 777 /var/spool/mqueue
service sendmail restart

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



Be advised that Google has hinted that the Gmail Smarthost landscape may be changing. See our recent article for a simple SmartHost alternative.

Incredible PBX 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 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.

admin-pw-change is used to set the admin password for access to the FreePBX/Incredible PBX web GUI using a browser pointed to the local IP address of your server.

apache-pw-change is used to set the admin password for access to Apache/Incredible PBX apps including AsteriDex and Reminders. This provides a password layer of protection for access to these applications.

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 702-705. 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 actually is. A similar listing is available in the GUI at Admin -> Feature Codes.

show-passwords is a script that displays most of the passwords associated with Incredible PBX. 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.

ssh-regen.sh allows you to reset the SSH keys for your server for added security.

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.

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 15 Modules Current

We strongly recommend that you periodically update all of your FreePBX modules to eliminate bugs and to reduce security vulnerabilities. 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
/root/sig-fix

Amazon’s Polly TTS Returns for Incredible PBX 2021




In a word, WOW! If you’ve previously used text-to-speech (TTS) applications with Incredible PBX™ or any other PBX, you fully appreciate the challenges of getting excellent voice quality from a synthesized voice. In addition to operating system quirks, you also had to scramble to find TTS software that had acceptable voice quality without breaking the bank. Well, it’s a new day with Incredible PBX 2021. Shortly after Amazon’s introduction of Polly TTS, we integrated it into the Wazo platform with Incredible PBX. However, because of Debian dependencies, we were unable to migrate it to CentOS. With RedHat’s recent decision regarding CentOS, we introduced Incredible PBX 2021 for Debian. And now is a perfect time to bring back Polly TTS as well. Polly TTS provides not only incredible voice quality but it comes at an unbelievable price point. Your first year is free for the first 5 million characters each month. After that and in subsequent years, it’s $4 for every million characters of TTS translation, and you only pay for the characters used. But, don’t take our word for it. Listen to this sample. The clip’s introduction uses the free Pico TTS voice. The Yahoo News headlines were generated with Polly. Can you say Night and Day?

The beauty of Nerd Vittles projects is it’s all about the freedom to choose rather than making do with choices selected by others. Today’s addition of the Polly TTS engine brings the number of TTS options supported with Incredible PBX 2021 to four. In addition to the free options of Festival and PICO, you now have two dirt cheap commercial alternatives that rival the voice quality of any available TTS application on the market. There’s IBM’s Watson which we are using for voicemail transcription. And now you have Amazon’s Polly TTS as well.




Stewart Nelson was kind enough to share his audio clip comparing the Top Four commercial TTS applications. You can judge them for yourself. The clips are played in the following order: Amazon Polly TTS, Google Translate, IBM Watson TTS, and Microsoft.

How New TTS Apps Will Work in Incredible PBX 2021. That’s only half of our story today. We also are introducing our proven TTS methodology that makes it easy to roll your own TTS applications and take advantage of the voice platforms already installed on your Incredible PBX 2021 server. In our new TTS design, there are three components. First, there’s a chunk of dialplan code that answers calls, prompts for input (if required), and then passes the call off for processing and generation of the TTS results using the desired TTS platform.

The processing and TTS components consist of two PHP/AGI scripts on Asterisk® servers. The results processing script actually obtains the data to feed to the TTS processing engine. For example, this could be news headlines or a local weather forecast. This script generates plain text suitable for processing by any TTS engine. Finally, a TTS script stores your user credentials (if required) and handles translation of the text results into an audio file using the TTS platform of your choice. It also plays the audio "results" to the caller. As you add new applications, all that is necessary is a short dialplan snippet and a results processing script to obtain the necessary text to feed the TTS processing script.

Here’s a sample Asterisk dialplan snippet for our Yahoo News Headlines application. Note that you need only change the pollytts line of code to switch TTS engines. Simple design!

;# // BEGIN nv-news-yahoo
exten => 951,1,Answer
exten => 951,n,Wait(1)
exten => 951,n,Set(TIMEOUT(digit)=7)
exten => 951,n,Set(TIMEOUT(response)=10)
exten => 951,n,AGI(picotts.agi,"Please hold while we get the headlines.",en-US)
exten => 951,n,AGI(nv-news-yahoo.php,10) ;  obtain latest 10 Yahoo NEWS Headlines
exten => 951,n,NoOp(News: ${NEWS}) ;  display NEWS in text format on Asterisk CLI
exten => 951,n,AGI(pollytts.php,"${NEWS}") ; pass NEWS to TTS engine for playback
exten => 951,n,Hangup
;# // END nv-news-yahoo

The picotts line (above) shows the syntax to use the Pico TTS engine instead of pollytts. The new line would look like the following. Doesn’t get much easier than this:

exten => 951,n,AGI(picotts.agi,"${NEWS}",en-US)

Getting Started. Here are the steps to get everything working with your existing Incredible PBX 2021 platform. First, you’ll need credentials from Amazon Polly after you create or sign in to your an Amazon AWS account. Enter "Polly" in the AWS dialog to add the service. Make note of your Amazon region while here. Then open your Security Credentials by clicking on your name and choosing My Security Credentials. Create a new Access Key ID and Secret. You’ll need these credentials as well as your Amazon region in a minute. Next, you’ll need to put the pieces in place on your Incredible PBX 2021 server to support Polly TTS. We’ve made this easy by bundling everything into a single tarball. Just log into your server as root, download the tarball, untar it, add MP3 support for SOX, run the included script to install the dialplan code, and edit the pollytts.php script to install your Amazon credentials. Install time: under a minute.

cd /var/lib/asterisk/agi-bin
cp -p nv-news-yahoo.php nv-news-yahoo-orig.php
cp -p nv-weather-zip.php nv-weather-zip-orig.php
wget http://incrediblepbx.com/nv-polly-install.tar.gz
tar zxvf nv-polly-install.tar.gz
rm -f nv-polly-install.tar.gz
apt-get -y install libsox-fmt-mp3
./install-polly-dialplan-incrediblepbx.sh
nano -w pollytts.php

 
Once the pieces are in place and the editor opens, insert your Amazon key, secret, and region code. Then save the file: Ctrl-X, Y, then ENTER.

Now you can test things out by picking up a phone connected to your PBX and dialing 951 for News or 947 for Weather by ZIP Code. Enjoy!

NEWS FLASH: This new installer works great on the Incredible PBX 2020 Raspberry Pi platform as well.

5 Minutes to Paradise: Incredible PBX in the Cloud for $25/Yr.



We’ve been building turnkey Incredible PBX® servers for virtual machine platforms for many years. Because the servers are built from images, typical install times have been 5 minutes or less with Proxmox, VirtualBox, and VMware ESXi. But the missing piece has always been a similar image install on a true cloud-based platform. This limitation was primarily due to the fact that we don’t own or control the available cloud platforms which typically limit image installs to operating systems such as CentOS, Debian, Ubuntu, and Windows.

Today we have more very good news. Our favorite low-cost hosting provider, Crown Cloud,1 has agreed to offer 5-minute turnkey installs of Incredible PBX 2020 for CentOS and Incredible PBX 2021 for Debian at a jaw-dropping $25 a year. You’ll have a fully-functioning, production-ready KVM platform including a free snapshot with 1GB RAM, 20GB SSD storage, and 1TB of monthly bandwidth in your choice of server locations including Los Angeles and Atlanta in the United States as well as Germany and the Netherlands in Europe. And, unlike all of the other Asterisk® aggregations, Incredible PBX still provides a source code-based platform that can be tailored to meet any special requirements you may need.

We don’t make a nickel on this deal so consider this our special thanks to all of our loyal fans.

Here are the links to sign up for the service and take advantage of these Incredible PBX deals:

UPDATE: 2GB/40GB KVM plans have now been released.

When you sign up for the service, choose any operating system as your default install. Then open a support ticket and request either the Incredible PBX 2020 for CentOS image or the Incredible PBX 2021 for Debian image be added into your template list of available operating systems. Once your server comes on line, open your CrownPanel and choose Reinstall and select Incredible PBX from either the available CentOS or Debian options. In less than 5 minutes, your server will be ready for you to login. Be sure to use SSH and NOT the VNC utility included in CrownPanel. This will assure that your desktop machine’s IP address gets whitelisted in the Incredible PBX firewall. Once you login, the Incredible PBX configurator will prompt you to set passwords for root login, admin login to FreePBX, and admin login credentials for Apache to access AsteriDex and Reminders. After a reboot to initialize your SSH keys, you’ll be ready to go. Add a trunk provider and a softphone, or Incredible PBX SIP phone, or GTI cell phone, and your PBX is fully operational. Check out the CrownCloud Wiki.


Planning Ahead for That Rainy Day

One of our favorite features of Crown Cloud is the free snapshot (a.k.a. backup) at no additional charge. We recommend you take snapshots regularly as you make major changes in your server’s configuration. In this way, if something comes unglued, you can easily restore the snapshot and never miss a beat. You’ll find the Remote Snapshot option in your CrownPanel menu.

Configuring Skyetel for Incredible PBX

If you’ve decided to go with Skyetel, here’s the drill. Sign up for Skyetel service and take advantage of the Nerd Vittles specials. 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 satisfied with the service, fund your account as desired, and Skyetel will match your deposit of up to $250 simply by opening another ticket. That gets you up to $500 of half-price calling. Credit is limited to one per person/company/address/location. Effective 10/1/2023, $25/month minimum spend required.

Skyetel does not require SIP registrations to make connections to your PBX. Instead, Skyetel can use 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:

  • Name: MyPBX
  • Priority: 1
  • IP Address: PBX-Public-IP-Address
  • Port: 5060
  • Protocol: UDP
  • Description: my.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 ClearlyIP SIP Trunking

For the tightest integration with FreePBX, no SIP provider holds a candle to Incredible PBX SIP Trunking with ClearlyIP. The reason is fairly obvious. The ClearlyIP folks were the original developers of FreePBX. In addition to all of the traditional SIP trunking services, you also get CNAM support and state-of-the-art E911 service which can be deployed in full compliance with Kari’s Law and the Ray Baum Act. If you’re a system integrator and don’t know about your financial liability for failure to comply with the new rules, it’s time to do some reading.

Configuring VoIP.ms for Incredible PBX

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 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. In the Incredible PBX GUI, be sure to enable the VoIP.ms trunk.

Configuring V1VoIP for Incredible PBX

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. In the Incredible PBX GUI, be sure to enable all of the V1VoIP trunks.

Configuring Anveo Direct for Incredible PBX

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. Enable the Trunk. Then click on the custom-Settings tab and replace anveo-pin with your actual Dialing Prefix. Click Submit and Apply Config to complete the setup. In the Incredible PBX GUI, be sure to enable all of the remaining Anveo trunks.

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 SIP Phone for Incredible PBX

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 is 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. We obviously recommend the Incredible PBX IP phones from ClearlyIP which are the most versatile.

If you’ve been keeping up with recent Nerd Vittles developments, then you already know that we have just introduced a new Cellular Phone which connects directly to your PBX and serves as a perfect remote extension and traveling companion. You can read all about it here.

Software devices such as the YateClient softphone are another option for desktop machines. 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 YateClient for Windows 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.

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.

For smartphone solutions, visit the Incredible PBX Wiki for our softphone recommendations.

Configuring SendMail with Incredible PBX

In order to receive voicemails by email delivery, outbound mail functionality from your server obviously is required. We strongly recommend configuring SendMail using either your ISP or Gmail as an SMTP Relay Host. 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. You also must enable Less Secure Apps access to the Gmail account.

Configuring a Gmail account with Incredible PBX 2021 is as simple as entering your Gmail credentials. Just run this script: /root/enable-gmail-smarthost-for-sendmail.

Here are the steps using a Gmail account with Incredible PBX 2020:

cd /etc/mail
yum -y install sendmail-cf
hostname -f > genericsdomain
touch genericstable
cd /usr/bin
rm -f makemap
ln -s ../sbin/makemap.sendmail makemap
cd /etc/mail
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 OR
#  use your Gmail App Key if 2-step verification is enabled
# 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

Even though these servers are hosted in the cloud, we still recommend using a SmartHost to minimize email delivery problems.

Test outbound mail using this command with your actual email address:

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

On some implementations, you may notice in the FreePBX GUI that the mail queue has failed. Here's the fix:

chmod 777 /var/spool/mqueue
service sendmail restart

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



Incredible PBX 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 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.

admin-pw-change is used to set the admin password for access to the FreePBX/Incredible PBX web GUI using a browser pointed to the local IP address of your server.

apache-pw-change is used to set the admin password for access to Apache/Incredible PBX apps including AsteriDex and Reminders. This provides a password layer of protection for access to these applications.

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 actually is. A similar listing is available in the GUI at Admin -> Feature Codes.

show-passwords is a script that displays most of the passwords associated with Incredible PBX. 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-asterisk16 is a script that updates your server to the very latest release of Asterisk 16. You can run it periodically to keep your server up to date with the latest and greatest features.

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.

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"

Getting Started with Incredible Fax

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. With Incredible PBX 2021, Incredible Fax is already installed. Simply set your email address for delivery of your faxes in PDF format, and you're all set: /root/avantfax-email-change. With Incredible PBX 2020, begin by logging into your server as root and running incrediblefax2020.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. The default credentials are 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:



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.

Keeping FreePBX 15 Modules Current

We strongly recommend that you periodically update all of your FreePBX modules to eliminate bugs and to reduce security vulnerabilities. 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

Free Cellular Service in the U.S. & Canada Returns

We’re a few months late to the party but, if Covid-19 has put a kink in your cellular budget or if you have young kids that could use a cellphone with unlimited calling and texting on the Sprint® network at zero cost in the U.S. and Canada, then your prayers have been answered. All you need is a CDMA phone and a $10 SIM card from TextNow. Better yet, you can purchase one of their refurbished iPhones or Android phones, and you’re off to the races. Their compatible web app with 200+ million downloads lets you make calls and send text messages from your favorite desktop computer or tablet. Special thanks to @Hometech for this tip.

What’s the Catch? The free tier is ad-supported so you’ll get a few ads. But, other than that, unlimited calling and texting throughout the U.S. and Canada are free whether you’re on WiFi or on Sprint’s nationwide network. If the ads are bothersome, you can always move up to the $10/month ad-free platform which also gets you voicemail transcription. There’s even free data service albeit on Sprint’s 2G network. But it’s perfectly suited for email. Yes, we’re aware of Sprint’s terrible coverage in some areas, but hopefully this will improve with the T-Mobile merger. Much like Google Fi, the TextNow design supports WiFi wherever it’s available. You can’t beat the price, and no credit card is required to sign up. So what are you waiting for?

Referral Code Saves $20. TextNow no longer offers referral codes or affiliate links, and we don’t have one. But here’s a link to some existing coupons that will save you $20 if you decide to purchase a phone from them.

Going Public with Incredible PBX 16 and VitalPBX 2.3.8



As part of our ongoing development efforts, we maintain about a dozen honeypot servers across the U.S. and Canada to monitor the latest adventures of the bad guys. Security becomes especially important for those wishing to live on the bleeding edge and deploy a cloud-based, public-facing VoIP server. Today we want to walk you through our latest suggestions to set up and secure a VitalPBX platform using just the built-in FirewallD, IPset, and Fail2Ban components. If you opt to deploy VitalPBX in the Cloud, a KVM-based VPS is absolutely essential in order to take advantage of the security mechanisms we will introduce today.

Here are 6 Key Security Features in today’s public design:

  • SIP Registration Lockdown by FQDN
  • Extension Lockdown by IP Address
  • Trunk Provider Lockdown by IP Address
  • Web Access Lockdown by WhiteList
  • Disguised Ports for SIP and SSH Access
  • 100,000+ VOIP Blacklist for FirewallD

Is it 100% safe? Nothing ever is. That’s what backups are for. 😉

FYI: The CentOS folks reintroduced a previous FirewallD bug on October 22 which (again) broke new VitalPBX installs. On October 23, the VitalPBX developers fixed the bug (again). There should be no problems with new installs. For previous installs, see this thread on the PIAF Forum for the fix.

Taking Incredible PBX with VitalPBX to the Cloud

Because Incredible PBX with VitalPBX 2.3.8 was originally distributed as an ISO, getting it installed in the cloud was a challenge. A few cloud providers let you bring your own ISO to install on their VPS platforms, but it was still a tedious process. So today we’re pleased to introduce a new install script that can be run on any CentOS 7 platform.

We have a few cloud providers that we recommend without reservation. Both Vultr and Digital Ocean provide referral credits to Nerd Vittles to support our VoIP project development efforts. We’ve used both of them for many years with no problems. Either of the platforms works well using the $5 a month option in your choice of cities. Just be sure to choose the CentOS 7 platform, not CentOS 8. For an extra buck, you can add automatic backups.

Our favorite bargain is now CrownCloud in Los Angeles. For $25 a year, they offer a KVM VPS that is ideal as a VoIP platform. And the offering includes a free snapshot image as well. As you might imagine, it’s very popular and goes Out of Stock from time to time so check back often. For our international friends, CrownCloud offers similar platforms at the same price point in both Germany and the Netherlands.

Installing Incredible PBX with VitalPBX on CentOS 7

Once your CentOS 7 platform is up and running, here’s how to install Incredible PBX for VitalPBX. Log into your server as root using SSH or Putty. Then issue these commands:

cd /root
passwd
yum -y install net-tools wget nano tar
wget http://incrediblepbx.com/incrediblepbx.sh
chmod +x incrediblepbx.sh
./incrediblepbx.sh

Incredible PBX Cloud Setup Recipe for VitalPBX

We think the easiest way to configure your new VitalPBX platform is to follow the simple steps outlined below. This will avoid your having to jump back and forth between tutorials to get all the pieces in place. When you’re finished, you’ll have a secure VitalPBX cloud platform. Don’t be intimidated by the number of steps. If you can handle slice-and-bake cookies, you can do this!

1. Point your browser to the IP address of your server. You’ll be prompted to set a password for admin access to the GUI. Fill in the blanks to proceed. Should you ever forget your admin password, here’s how as root user to force a reset on your next login from a browser:

mysql ombutel -e 'update ombu_settings set value = "yes" where name = "reset_pwd"'


2. Register your server when prompted. The VitalPBX Dashboard will appear.

3. Decipher the public IP address of your desktop machine and any other PCs that will be used to manage your server.

4. From the VitalPBX Dashboard, navigate to Admin:Security:Firewall:WhiteList. Enter each of your IP addresses from step #3 and click Save button.

5. From the VitalPBX Dashboard, navigate to Admin:Security:Intrusion Detection:WhiteList. Enter each of your IP addresses from step #3 and click Save button.

6. Modify the default SSH port by logging in to your server as root and issuing the following commands using the year you were born in the first line replacing 2000:

sed -i 's|#Port 22|Port 2000|' /etc/ssh/sshd_config
systemctl restart sshd

 
7. From the VitalPBX Dashboard, navigate to Admin:Security:Firewall:Services. Change the SIP port to 5080 or some other port number not in the 5060-5065 range. Change the SSH port to a 4-digit number matching the year you were born. Click Save button. Monitor your SSH log for attempted breaches and change your port if necessary:

cat /var/log/secure | grep password

 
8. Verify that you can log back into your server with SSH using the new SSH port number you assigned in step #6: ssh -p 2000 root@server-IP-address

9. From the VitalPBX Dashboard, navigate to Admin:Security:Firewall:Rules. Delete the HTTP and HTTPS items by clicking the Trash icon beside each entry. In the GENERAL tab, set Block ICMP Requests to YES. Click Save button. This blocks web access to everyone except those you’ve whitelisted in step #4 above. If you ever lock yourself out of web access, login to your server as shown in step #8 and temporarily whitelist the public IP address desired. This gets removed automatically the next time you save your Firewall settings from within the VitalPBX GUI.

iptables -A vpbx_white_list -s 12.34.56.78 -j ACCEPT

10. Before we get too far along, let’s put another layer of security in place for your new server. We’re going to add the VoIP Blacklist which blocks about 100,000 bad guys from around the globe. We’ll also add a cron job to update the blacklist every night. Log back into your server as root and issue these commands to put the pieces in place and enable the VoIP Blacklist.

TIP: The cron job below is scheduled to run at 20 minutes after 3 a.m. Change the time to something else so we don’t all bombard the VoIP Blacklist site for downloads at exactly the same time every night.

cd /etc
wget http://incrediblepbx.com/voipbl-firewalld.tar.gz
tar zxvf voipbl-firewalld.tar.gz
rm -f voipbl-firewalld.tar.gz
echo "20 3 * * * root /etc/update-voipbl.sh >/dev/null 2>&1" >> /etc/crontab
/etc/update-voipbl.sh

11. From the VitalPBX Dashboard, navigate to Admin:Add-Ons:Add-Ons. Click Check Online button. Click Install button beside Custom Contexts. Click Install button beside Phonebooks. Click Install button beside Domotic.

12. From the VitalPBX Dashboard, navigate to Settings:Tech Settings:SIP Settings.

  a. In the GENERAL tab, set the Bind Address port to 5080 or whatever port you chose in step #7 above. This is the port number together with the FQDN of your PBX (set in the next step) that any SIP phone will need to successfully register to an extension.

  b. In the SECURITY tab, set Allow Guest to NO, set Auto-Domain to NO, set Allow External Domains to NO, and enter a fully-qualified domain name (FQDN) pointing to the IP address of your server in the Domain field. We cannot stress enough how important this FQDN is to the security of your cloud-based server. It limits SIP registrations to this FQDN only, and all SIP registration attempts by IP address are automatically blocked. Don’t skip this step!

  c. In the NETWORK tab, enter the IP address of your server in External Address. Click the ADD button in the Local Networks section and enter the private IP addresses associated with your LAN and VPN, e.g. 192.168.0.0/255.255.0.0 and 10.0.0.0/255.240.0.0. Change NAT to Force,Comedia if your server is behind a NAT-based router.

  d. In the CODECS tab, enable ULAW, ALAW, G722, and G729.

  e. In the OTHERS tab, set SRV LOOKUPS to Yes. Click SAVE button.

13. From the VitalPBX Dashboard, navigate to Settings:Tech Settings:Profiles. Click Show All Profiles bar and choose Default PJSIP Profile. In the GENERAL tab, set the following entries to YES: Force rport, Rewrite Contact, Direct Media, RTP Symmetric, and Send Diversion Header. Click UPDATE button.

14. From the VitalPBX Dashboard, navigate to PBX:Applications:Parking. Click Show All Parking Profiles bar and choose Default. Change Code from 700 to 7000 and click Update button. This changes your Parking Lot extensions to the 7000 range so that 700 range can be used for Extensions, just like other versions of Incredible PBX.

15. Log out of your Dashboard and then log back in so that the menus get refreshed with the Custom Contexts addition.

16. From the VitalPBX Dashboard, navigate to PBX:Applications:Custom Contexts. Create the new sample IVR context with the following entries. Then click Save button.

  • Description: IncrediblePBX
  • Context: incrediblepbx
  • Extension: s
  • Priority: 1
  • Destination: Terminate Call -> Hangup

17. From the VitalPBX Dashboard, navigate to PBX:Applications:Custom Applications. Create the custom application for the sample IVR and Save it.

  • Code: 3366
  • Name: DEMO
  • Enabled: YES
  • Destination: Custom Contexts -> IncrediblePBX

18. From the VitalPBX Dashboard, navigate to PBX:Applications:Conferences. Create the new sample conference application and Save it.

  • Code: 2663
  • Description: CONF
  • Music on Hold When Empty: YES
  • User Count: YES
  • Announce Join/Leave: YES
  • Announce Only User: YES
  • User PIN: 1234
  • Leader PIN: 4321
  • Drop Silence: YES

19. If you didn’t read last week’s article on Custom Contexts, now would be a good time to do so. Here are the commands to put all those pieces in place on your new cloud-based server:

cd /
yum -y install dialog wget nano tar mailx
cp -p /etc/crontab /etc/crontab.bak
wget http://incrediblepbx.com/incrediblepbx-vitalpbx.tar.gz
tar zxvf incrediblepbx-vitalpbx.tar.gz
rm -f incrediblepbx-vitalpbx.tar.gz

20. Create new Extensions for your PBX by navigating to PBX:Extensions:Extensions. You only need to fill in the Extension, Name, and Email Address fields. We recommend extension numbers beginning with 701. If the extension will be used from a phone behind a NAT-based router, change the NAT entry to Force,Comedia. If the phone associated with the extension has a static IP address, enter it in the Permit field for an extra layer of security. In the VOICEMAIL tab, you will note that voicemail is enabled by default with a password matching the extension number. This forces the user to set the voicemail password the first time they access voicemail with their phone. We recommend the YES setting for Attach Voicemail, Ask Password, Say CID, Say Duration, and Envelope. Then press SAVE.

21. Once you have created your extensions, you can create Ring Groups to assign multiple extensions and external numbers to a designated number which will ring all of the extensions and external numbers in the ring group either simultaneously or serially. Navigate to PBX:Call Center:Ring Groups to set this up.

22. Trunk Setup. While we don’t recommend it, if you just want to play around with some toll-free calls using option 1 in the DEMO IVR to see how everything works, here’s a simple trunk setup to get you started. First, navigate to Settings:Telephony:Channel Groups and save a group named Default with no entries. Then navigate to PBX:External:Trunks:CUSTOM. Create TollFree trunk with this Dial String: SIP/1${EXTEN}@ovh.starcompartners.com. No other entries are required. Click SAVE and reload your dialplan. Finally, create an Outbound Route for these calls in PBX:External:Outbound Routes like this:

  • Description: TollFree
  • Trunks: TollFree
  • Dial Pattern: Pattern=NXXNXXXXXX

Save your settings and reload the dialplan. You now can skip down to step #25. NOTE: You will not be able to receive outside calls or make calls to numbers other than toll-free ones.

Our preference is that you use our Platinum Provider, Skyetel, for your default trunk and DID because they offer quadruple redundancy so you never miss a call. Sign up for Skyetel service and take advantage of the Nerd Vittles specials which include a $10 credit to kick the tires. 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 satisfied with the service, fund your account as desired, and Skyetel will match your deposit of up to $250 simply by opening another ticket. That gets you up to $500 of half-price calling. You can also port in your DIDs at no cost for 60 days after funding your account. Credit is limited to one per person/company/address/location. Effective 10/1/2023, $25/month minimum spend required.

We don’t recommend trunk registrations with a publicly exposed server because it creates a potential attack vector for intruders and any intrusion would be undetectable from the PBX since the attacker could make unauthorized calls after registering directly with your SIP provider. For this reason, 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 for VitalPBX:

  • Name: IncrediblePBX
  • Priority: 1
  • IP Address: IncrediblePBX-Public-IP-Address
  • Port: 5062
  • Protocol: UDP
  • Description: my.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 and 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.

If you’d like additional details on why we recommend Skyetel, see this Nerd Vittles article.

On the VitalPBX side, we need to add a new Skyetel trunk. Navigate to PBX:External:Trunks:PJSIP. The VitalPBX Trunk setup should look like the following for Skyetel. If you’d like to cut-and-paste the entries for the Match field, here you go:

52.41.52.34,52.8.201.128,52.60.138.31,50.17.48.216,35.156.192.164


[popup url="https://pbs.twimg.com/media/EGDhgsXWsAIbmw1?format=jpg&name=medium" width="1200″ height="700″][/popup]

In Admin:Security:Firewall:WHITELIST, you’ll need to individually Add the five Skyetel IP addresses used in the Match field above and then SAVE your firewall settings.

Finally in PBX:Incoming Calls:CID Modifiers, add a new entry for Skyetel with Skip/Length = 2/10 and Save your settings.

23. Before your PBX can receive calls, you’ll need at least one Inbound Route. This tells the PBX how to route calls from one or more phone numbers (DIDs) that you own to a destination on your PBX, e.g. an extension, a ring group, an IVR, or custom context. Navigate to PBX:External:Inbound Routes to get started. Let’s set up a default inbound route for all the DIDs you have acquired from Skyetel in step #22. Fill in the fields shown below. Then SAVE.

  • Routing Method: Default
  • Description: Default Skyetel
  • DID Pattern: [leave blank for ALL DIDs]
  • CallerID Modifier: Skyetel
  • Inbound Destination: Custom Contexts -> IncrediblePBX

24. Before you can make outbound calls from extensions on your PBX, you’ll need at least one Outbound Route. This tells the PBX which provider to use to complete calls dialed with a certain sequence of numbers. For example, you probably would want 10-digit numbers routed to Skyetel. And, if users dial 1 and then a 10-digit number, you’d probably want those calls routed to Skyetel as well. To create this outbound route, navigate to PBX:External:Outbound Routes. Fill in the fields shown below. Click ADD to add a second Dial Pattern. Click SAVE and Reload Dialplan when finished.

NOTE: While you can "spoof" any CallerID number here, it is only legal to assign CallerID numbers that you actually own. Most carriers do not forward CallerID names to destinations regardless of what you enter here. The CallerID name and number will be shown in your CDR logs: Reports:CDR Reports:CDR.

  • Description: Skyetel-OUT
  • Trunks: Skyetel
  • Outbound CID: [Your Name and CallerID Number]
  • Overwrite CID: YES
  • Dial Pattern: Prepend=1 Pattern=NXXNXXXXXX
  • Dial Pattern: Pattern=1NXXNXXXXXX

25. For the time being, we strongly recommend disabling IPv6 simply because we don’t have the necessary confidence that all of the security mechanisms are in place for IPv6. Here’s how on the CentOS 7 platform:

echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
sysctl -p
sed -i 's|#AddressFamily any|AddressFamily inet|' /etc/ssh/sshd_config
systemctl restart sshd
sed -i 's|inet_protocols = all|inet_protocols = ipv4|' /etc/postfix/main.cf
systemctl restart postfix

 
26. Outbound email functionality is essential on your PBX. You’ll need it to be alerted to potential issues with VitalPBX, and you’ll need it for delivery of voicemail messages to users. There are a couple ways to implement it, and both are easy. If you want to use the native capabilities of Postfix to send the emails assuming your provider is not blocking outbound SMTP mail from downstream servers, then follow these steps:

  • Insert your FQDN from step #12b into /etc/hosts immediately after 127.0.0.1
  • Replace the contents of /etc/hostname with the same FQDN
  • Issue the following command using your actual FQDN: hostname FQDN
  • Sending yourself an email: echo "test" | mail -s test you@your-domain.com

If you don’t receive the test email message, then the easiest solution is to configure PostFix as an SMTP Relay using a Gmail account. You can do this easily from within the VitalPBX GUI. Navigate to Admin:System Settings:Email Settings and click the External Mail Server tab. Be sure that Gmail is selected and enter your Gmail name and password in the fields provided. Save your settings and send yourself an email using the field provided.

27. Once you get outbound email flowing, jump down to the next section and obtain IBM TTS and STT passwords. Now set up Voicemail Transcription with Email Message Delivery:

  a. After logging into your VitalPBX server as root using SSH/Putty:

cd /tmp
mkdir sendmail
cd sendmail
wget http://incrediblepbx.com/sendmailibm-vitalpbx.tar.gz
tar zxvf sendmailibm-vitalpbx.tar.gz
rm -f sendmailibm-vitalpbx.tar.gz
mv usr/sbin/sendmailibm /usr/sbin
cd /etc/asterisk/ombutel
echo "[general](+)" > voicemail__60-1-transcript.conf 
echo "; format=wav|wav49|gsm" >> voicemail__60-1-transcript.conf
echo "mailcmd=/usr/sbin/sendmailibm" >> voicemail__60-1-transcript.conf
chown apache:apache voicemail__60-1-transcript.conf
rm -rf /tmp/sendmail

 
  b. Restart Asterisk core services: asterisk -rx "core reload"

  c. Edit /usr/sbin/sendmailibm and insert your IBM Watson STT APIkey on line 23. Change the language on line 31 if you don’t want en-US. Then save the file.

  d. Log back into the VitalPBX GUI and configure the extensions desired for email delivery of voicemail. For each extension in PBX:Extensions:General, enter an Email Address for delivery of voicemails. In PBX:Extensions:Voicemail, verify the VM settings from step #20.

28. We hesitate to even mention (free) Festival TTS as a text-to-speech alternative because it is so bad compared to IBM TTS. But for those that like always free, here’s how to install it. Once installed, you can issue Festival commands in your dialplan using the keyword Festival followed by the text to be spoken in parentheses.

yum -y install festival
echo "[general]" > /etc/asterisk/festival.conf
asterisk -rx "dialplan reload"
festival_server &
systemctl restart asterisk
echo "/usr/bin/festival_server &" >> /etc/rc.d/rc.local

 

29. If you’d like to test the performance of your cloud-based server, here’s how to deploy and run SpeedTest:

cd /root
wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py
chmod +x speedtest-cli
/root/speedtest-cli

 
30. Associating CallerID Names (CNAM) with inbound calls for display on SIP phones and in the CDR logs is an often-requested PBX feature. There are a few ways to do it. First, for less than a penny a call, you can activate the feature with your DIDs in the Skyetel Dashboard. Or, for about half the cost, you can acquire an OpenCNAM account and activate it in VitalPBX by navigating to PBX:Incoming Calls:CID Lookup. Choose OpenCNAM as the Source and enter your credentials. Then SAVE your settings and reload the dialplan. Then, for each of your Inbound Routes, add OpenCNAM as the CID Lookup source and Update your configuration.

31. Unless you want a full-time job monitoring the size of your logs, remove the fail2ban Asterisk log which grows every 5 seconds. Navigate to Settings:PBX Settings:Log Files and click the Trash icon beside fail2ban. It’s probably a good idea to turn OFF the Notice option for the full log while you’re at it. Then SAVE your changes.

32. Before you do anything else, navigate to Admin:Admin:Backup & Restore, configure and run a Full Backup, and then download the file and keep it in a safe place. Be advised that Backup/Restore doesn’t restore Add-Ons, /var/lib/asterisk/agi-bin, custom contexts (extensions__80*.conf) in /etc/asterisk/ombutel, custom MySQL databases (mysqldump -u root yourDB > yourDB.sql), custom and lenny sound directories in /var/lib/asterisk/sounds, phpMyAdmin, /usr/local/sbin, and /etc/crontab.

Obtaining IBM Watson TTS and STT Credentials

Incredible PBX uses IBM Watson® for TTS and STT support. This Nerd Vittles tutorial will walk you through getting your IBM account set up and obtaining both your TTS and STT credentials. Be sure to write down BOTH sets of credentials which you’ll need in a minute. For home and SOHO use, IBM access and services generally is FREE even though you must provide a credit card when signing up. Details are provided when you sign up. If you ever forget your passwords, you can retrieve them by navigating to Resource List:Services:TTS or STT:View Full Details:Show Credentials.

Obtaining Wolfram Alpha Credentials

When people ask what exactly Wolfram Alpha is, our favorite answer was provided by Ed Borasky.

It’s an almanac driven by a supercomputer.

That’s an understatement. It’s a bit like calling Google Search a topic index. Unlike Google which provides links to web sites that can provide answers to queries, Wolfram Alpha provides specific and detailed answers to almost any question. Here are a few examples (with descriptions of the functionality) to help you wrap your head around the breadth of information. For a complete list of what’s available, visit Wolfram Alpha’s Examples by Topic. Type a sample query here. Some of our favorites include:

Before you can actually use our TTS implementation of Wolfram Alpha, you’ll need to obtain a free Wolfram Alpha account. As you can imagine, there have to be some rules when you’re using someone else’s supercomputer for free. So here’s the deal. It’s free for non-commercial, personal use once you sign up for an account. But you’re limited to 2,000 queries a month which works out to almost 70 queries a day. Every query requires your personal application ID, and that’s how Wolfram Alpha keeps track of your queries. Considering the price, we think you’ll find the query limitation generous compared to other web resources.

To get started, sign up for a free Wolfram Alpha API account. Just provide your email address and set up a password. It takes less than a minute. Log into your account and click on Get An App ID. Make up a name for your application and write down (and keep secret) your APP-ID code. That’s all there is to getting set up with Wolfram Alpha. If you want to explore costs for commercial use, there are links to let you get more information.

Configuring Your Incredible PBX Credentials

In addition to your Wolfram Alpha APPID, there are two sets of IBM credentials to plug into the Asterisk AGI scripts. Keep in mind that there are different passwords for the IBM Watson TTS and STT services. The TTS credentials will look like the following: $IBM_password. The STT credentials look like this: $API_PASSWORD. Don’t mix them up. The username for both TTS and STT is now the single word: apikey

All of the scripts requiring credentials are located in /var/lib/asterisk/agi-bin so switch to that directory after logging into your server as root. Edit each of the following files and insert your TTS credentials in the variables already provided: nv-today2.php, ibmtts.php, and ibmtts2.php. Edit each of the following files and insert your STT credentials in the variables already provided: getquery.sh, getnumber.sh, and getnumber2.sh. Finally, edit 4747 and insert your Wolfram Alpha APPID.

If you ever want to learn how to develop applications for Asterisk, these scripts coupled with the dialplan code included in /etc/asterisk/ombutel/extensions__80-1-incrediblepbx.conf will point you in the right direction with easy to follow examples.

Managing the AsteriDex SQLite3 Database

We’ve alluded to the AsteriDex database in a couple of VitalPBX articles but never mentioned how to access it. Using a browser, point it to http://server-ip/asteridex4. You can add, edit, display, and delete entries from there. Before you can make changes in the database, issue the following command after logging into your server as root:

chown asterisk:apache /var/lib/asterisk/agi-bin

Taking Incredible PBX for a Test Drive

You can take Incredible PBX for VitalPBX on a test drive in two ways. You can call our server, and then you can try things out on your own server and compare the results. Call our IVR by dialing 1-843-606-0555. For our international friends, you can use the following SIP URI for a free call: 10159591015959@atlanta.voip.ms. For tips on setting up your own secure, hybrid SIP URI with VitalPBX, see our original tutorial. The FreePBX® setup is virtually identical except for the location of the custom SIP setting for match_auth_username=yes. On a VitalPBX server, you will enter it here: Settings:Technology Settings:SIP Settings:CUSTOM.

With Allison’s Demo IVR, you can choose from the following options:

  • 0. Chat with Operator — connects to extension 701
  • 1. AsteriDex Voice Dialer (412) – say "Delta Airlines" or "American Airlines" to connect
  • 2. Conferencing (2663) – log in using 1234 as the conference PIN
  • 3. Wolfram Alpha Almanac (4747) – say "What planes are flying overhead now?"
  • 4. Lenny (53669) – The Telemarketer’s Worst Nightmare
  • 5. Today’s News Headlines (951) — courtesy of Yahoo! News
  • 6. Weather by ZIP Code (947) – enter any 5-digit ZIP code for today’s weather
  • 7. Today in History (86329) — courtesy of OnThisDay.com
  • 8. Call Extension 701 — on your local PBX
  • 9. DISA Voice Dialer (3172) — say any 10-digit number to be connected
  • *. Current TIME and Date (8463) — courtesy of VitalPBX

CAUTION: We have intentionally disabled outbound calls using Option #9 and redirected callers to Lenny. The reason is that an unscrupulous caller could easily run up your phone bill by entering a number with expensive destination charges. If you wish to enable the feature, despite the risks, you can edit extensions__80-1-incrediblepbx.conf and make the change.

You can call your own IVR in a few ways. From an internal VitalPBX phone, dial D-E-M-O (2663) to be connected. Or simply dial the number of the DID you routed to the Incredible PBX Custom Context. Local users can also dial the individual feature codes shown in parentheses above. Be sure that you heed AND test the CAUTION documented above.
