Hello, everybody,
I have now invested a few hours on the weekend and set up Jigasi with Jitsi. For this I have now also installed a FreePBX system. I have reached the point where you can dial in from outside, the PIn is asked for and then Jigasi does not do what it should 
It is shown in the conference that a participant is added. After a few seconds the connection is terminated.
Unfortunately I can’t really figure out the LogFile

I’ve been looking for those “flaws”
Could not invite the focus to the conference
XMPP error reply received from focus.meet.enbitcon.de: XMPPError: not-acceptable - modify

The last one, I came across this thread
Seems to be the same problem.
Does anyone here have any idea what attitude I may have forgotten?
