Introducing Incredible PBX 2022 for Rocky 8 Linux

As we celebrate the 17th birthday of Nerd Vittles this week, it seemed only fitting to introduce a new version of Incredible PBX 2022 which will carry telephony forward until the end of this decade. For history buffs, you may recall that CentOS used to be a perfect clone of Red Hat Enterprise Linux… until it wasn’t when RedHat decided to morph CentOS into a development sandbox known as CentOS Stream. And then along came Gregory Kurtzer, the original developer of CentOS, to work his magic once again with the Rocky 8 reincarnation. Until Rocky 8 rose from the ashes, we had all but decided to end our CentOS distribution and focus on Debian, Raspbian, and Ubuntu. But the appeal of a new operating system with an end of life slated for May 2029 was hard to resist. So here we are.

Our roadmap for Incredible PBX 2022 for Rocky 8 goes like this. Today we are introducing this beta featuring Asterisk® 16 and the GPL modules from FreePBX® 15. Once we get the kinks out of this release, we will add two additional versions, one featuring Asterisk 18 and FreePBX 15 plus a second one featuring Asterisk 19 and FreePBX 16. The PHP platform to support all three versions is already in place. It supports both PHP 5.6 and PHP 7.4 running concurrently. We needed PHP 5.6 to preserve the legacy AvantFax application which provides free faxing.

CAUTION: Because of frequent changes to the Rocky 8 platform, we no longer recommend it for production use with Incredible PBX.

We hope you’ll download and install Rocky 8 as well as Incredible PBX 2022 and help us move this platform forward. Begin by downloading and installing Rocky 8 Minimal. If you prefer AlmaLinux, download and install their minimal image from here. If you prefer a cloud-based platform, consider our Platinum sponsor, Vultr. They host both Rocky 8 and AlmaLinux 8 images in addition to other operating systems so platform setup takes only a minute.

Once you have your platform up and running, login as root and issue the following commands to kick off the Incredible PBX 2022 install:

cd /root
yum -y install wget
wget http://incrediblepbx.com/IncrediblePBX2022.16.15-4.sh
chmod +x IncrediblePBX2022.16.15-4.sh
./IncrediblePBX2022.16.15-4.sh

Once the Phase I install finishes, your server will reboot. Log back in as root and run the installer a second time:

cd /root
./IncrediblePBX2022.16.15-4.sh

1/31/2022 UPDATE: We’ve now released the second iteration of Incredible PBX 2022 for Rocky8 and AlmaLinux8 featuring Asterisk 18 and the FreePBX GPL modules. You can install this version as an alternative to the Asterisk 16 release if you would prefer:

cd /root
yum -y install wget
wget http://incrediblepbx.com/IncrediblePBX2022.18.15-1.sh
chmod +x IncrediblePBX2022.18.15-1.sh
./IncrediblePBX2022.18.15-1.sh

Once the Phase I install finishes, your server will reboot. Log back in as root and run the new installer a second time:

cd /root
./IncrediblePBX2022.18.15-1.sh

If you chose to install AlmaLinux 8, issue the following command once you’ve logged in to the Linux CLI as root:

sed -i 's|Rocky 8|AlmaLinux 8|' /usr/local/sbin/pbxstatus

As with all Incredible PBX builds, a preconfigured Linux firewall is included which blocks all access except from whitelisted IP addresses. To activate it, simply press the ENTER key when the install completes. To load the latest updates to the platform using the Automatic Update Utility, simply log out of your server and log back in as root. You’re now ready to explore the Incredible PBX feature set using the tutorials available on the Incredible PBX Wiki.

Audio Issues with Incredible PBX

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

Incredible PBX 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 as root 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 2020 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 2020 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 2020. This includes SIP extension passwords, voicemail pins, conference pins, telephone reminders pin, and your Anveo Direct outbound calling pin (if configured). Note that voicemail pins are configured by the user of a SIP extension the first time the user accesses the voicemail system by dialing *97.

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

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

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"
