Secondly FreePBX never had a EPM. The OSS one was community supported from day 1 and built by the community. The commercial one was a product Schmooze had 7 years ago for their PBXact PBX only and due to community begging for us to release it as a paid module we did. That was 5 years ago.
2 years ago when I had to do some major number crunching on what our cost were in things EPM alone had over a 750K cost into that module. Now days it would be well over 1M USD. So asking for 75.00 to use it is a small fee.
