We’re getting many partnership requests from FreePBX users since Sangoma is still using Centos 7 and hasn’t mentioned moving to a different OS.
FreePBX’s system relies on macros, which Asterisk 21 won’t support. Sangoma hasn’t announced an update to make FreePBX compatible with Asterisk 21.
We requested ChatGPT to provide a neutral comparison of VitalPBX and FreePBX for users seeking to understand their distinctions. Here’s the answer:
“VitalPBX and FreePBX are both popular IP-PBX (Internet Protocol Private Branch Exchange) platforms used for setting up and managing VoIP (Voice over Internet Protocol) communication systems. While they share similar goals of providing feature-rich telephony solutions, there are some differences between the two platforms. Here’s a comparison of VitalPBX and FreePBX:
VitalPBX: VitalPBX has a modern and user-friendly web interface, making it relatively easy for users to navigate and configure the system.
FreePBX: FreePBX also offers a web-based GUI, but some users find it slightly more complex compared to VitalPBX’s interface.
VitalPBX: VitalPBX provides a simple installation process and offers regular updates with new features and bug fixes.

These are some features of each system. We see that many of the FreePBX modules have already gone commercial.
When an App has third-party modules, maintenance is difficult since when updating our main App we must be sure that the new version is compatible with third-party modules. Also at the time of an issue it is not easy to determine if the error is from the third-party module or from the main App.
For obvious reasons, we do not list basic functionalities such as extension creation, trunks, etc.
Although both PBXs are stable and effective, it’s important to consider security options while picking one. So take into consideration the following questions:

Whether you choose VitalPBX or FreePBX depends on your specific needs, platform expertise, support, and features.
Both platforms are powerful and capable of delivering feature-rich VoIP solutions for businesses of all sizes. It’s recommended to test each platform and see which one aligns better with your needs and preferences.
