I read on here that this is typically caused by a mis-match in CODEC. I see that you have many voice codecs, so perhaps it is a video CODEC? I copied your log to the FreeSWITCH pastebin which highlights the log lines when set to "FreeSWITCH" language. https://pastebin.freeswitch.org/view/a57f10d5#L97 2022-05-19 09:22:03.455283 [DEBUG] mod_sofia.c:866 Disabling proxy mode due to call answer with no bridge After the SDP lines I see a second routing attempt which immediately fails, but I see no outbound Leg-B set up. Do you add another party to the conference bridge via a script? That might be where the problem is.
