Jigasi unable to join room on incoming SIP call

Hi,

I use jitsi-meet in a docker install, jigasi connected to a FreePBX. Outgoing SIP calls work fine, incoming calls detect the correct conference room and then run into an error, resulting in the call getting dropped.

Any ideas, anyone? It seems that jigasi tries to somehow find the “canonical room name” and fails.

Any help appreciated.

Regards
Thomas

Hi again,

i did further testing (or lets call it experimenting) and got a little further (so it seems): the call gets accepted, I see a user joining the meeting, but then the call immediatly gets dropped again.

It looks as if there is an issue with getting RTP to the sip server. Which is strange, as it works for dial out.

Still and again, any hints are appreciated.

(next step: will try to packet capture on the docker host, to see if I can witness rtp packets.)

Hi again,

could this be a codec issue? I’m running out of ideas here now. Will stop debugging for today…

I tried changing the codecs accepted by jigasi and/or asterisk. Back to default now. In between, I also had the behaviour, that upon dial-in call join, the web conference would crash and reconnect. Can’t reproduce now.

I have set

net.java.sip.communicator.impl.protocol.sip.acc1.OVERRIDE_ENCODINGS=false

now, so I assume I am trying with jigasi default codec order. However, no success.

If someone could pass me a few ideas where to look for the issue, I’d appreciate.
Latest log below.

Regards,
Thomas

Followed you yesterday having the exact same issue. Found the solution as you did in the other thread and cross link here.

First unable to join room: the fqdn room name seems to be <room>@muc.meet.jtisi (so you have to get your PBX to send this or make this default in jigasi)

Second for connection drop immediately, see this thread
