On top of that the Sangoma 7 Distro also includes access to the EPEL repository, also known as “Extra Packages for Enterprise Linux”. Which gives FreePBX stability from upstream Red Hat. It’s seen many iterations over the last 10 years but it is still primarily based on the CentOS and RHEL distro releases. The Sangoma Distro started it’s life close to 10 years ago as the Schmooze Distro (way back with CentOS 5) and slowly morphed/grew/upgraded into the FreePBX Distro and now the Sangoma Distro. The “7” references the “7” in the CentOS Distro and RHEL 7. This means that the Sangoma Distro itself is a variant of Red Hat. The Sangoma Distro is a derivative of CentOS which itself is a Linux distribution that provides a free, enterprise-class, community-supported computing platform functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). If you’ve been around the forums long enough you’ve probably seen posts and comments from our staff and even our users referring to the “Sangoma 7 Distro” or “SNG7”.
