Sorry, I feel like I missed something here. I was under the impression that the telephony system in LMCE was Asterisk. I have heard AMP mentioned which I assumed was a version of Asterisk, but also freepbx. That last bit I didn't really understand as it would seem to be (from the name alone) a duplication.... so I just assumed it was a plugin or something like that to Asterisk, but as I am not yet at the point were I can set up VoIP I didn't really think about it much...
But I just read something that seemed to suggest that Asterisk (or at least AMP if that is different) is no longer used from 0710b3 onwards and has been replaced with freepbx. Is this true? Or what is the difference?
