Where can I find a sane source of information on FusionPBX/Freeswitch?

Question

FreeSWITCH

There are a number of questions on the subject that go beyond the basic settings.
Checked the official wiki. I studied one and a half articles on Habré. Books Freeswitch 1.2 and Freeswitch cookboock gnawed. Google does not know the answers to most questions on the topic. Googled forums are either empty or dead.
Prompt a live active forum or a warehouse of good articles on fusionpbx.

Answer 1

asterisk-pbx.ru/wiki/doku.php/freeswitch/fusionpbx
a bit, but at least something...

Answer 2

freepbx religion does not allow to use ? what motivates the choice of a particular software?

Answer 3

fusionpbx is just another GUI for housewives.
It is enough to know Freeswitch and how the plan is implemented by basic means.
Work out the logic and implement it on fusionpbx.

Answer 4

I advise you to spend a little time, demolish fusionpbx, install pure FreeSWITCH and figure out how XML configs work. Everything is simple, clear and logical. If there are any specific questions "going beyond the basic settings" of FS (NOT Fusion) - ask.
