Reboot & Register the Distro
Good Read on a little debate between a Ward Mundy the main man for IncrediblePBX and a FreePBX rep.
"Each Commercial Module is tested and built for the FreePBX Distro, which runs SHMZ OS (maintained by Schmooze for use with our Distro, and AsteriskNow), which is based/Derived on RHEL and CentOS. Non-FreePBX Distro systems, such as PIAF, do not come with support for the FreePBX Commercial Modules at install. You need to install a few packages and a FreePBX module to register your system. Please follow this guide on how to enable support for the FreePBX Commercial Modules. Commercial Modules are only officially supported on the FreePBX Distro. Any FreePBX system with FreePBX 2.10 or greater, CentOS/RH/SL/EL 6.x and php 5.3 should work with most Commercial Modules, but there are no guarantees that all features and functions will work. You are on your own if there are issues. As for Ubuntu, FreePBX and many of the Commercial module dependencies may require the installation of RPMs. We do not package programs for Ubuntu at this time, as there is not a huge demand, and the efforts to do so would be redundant to our work with SHMZ OS, as well as take away development cycles from advancing the core open source platform. Another reason we only focus on one OS, is this allows us to provide updates in place for not just FreePBX, but the entire PBX platform, making it much easier for end users to keep their systems up-to-date, without having to do a wipe and rebuild, for the Distro we provide updates for not only FreePBX, but also the OS, Asterisk and the hundreds of other dependencies in a Distro, this would be impossible if we supported every Linux variant available." - reconwireless FreePBX Rep
