I try to attach Bravis video conference clients to Freeswitch. Those video conference clients are really working good (Multilingual clients for testing ca be downloaded here: http://www.bravis.eu/). Some big companies here in Germany use them in large installations. They are based on SIP, but do not use any publicly known codecs. Normally they are maintained and routed via our OpenSIPS server, but I would like to integrate them into our Freeswitch system. That way I do not have to manage 2 SIP servers for phone calls and video conferencing calls. However the SIP message does not provide Content-Type: application/sdp. Instead it provides Content-Type: application/BRAVIS. The clients register successfully but they do not invite. Freeswitch answers "SIP/2.0 415 Unsupported Media Type." I have added bypass_media=true into the dialplan and inbound-late-negotiation true in the internal profile but this didn't help. I think Freeswitch complains about the content-type. Is there any way how I may overcome this? Here is a sample Invite INVITE sip:835352@sip5.mydomain.com SIP/2.0. From: myname <sip:835351@sip5.mydomain.com>;tag=5c5c3ef6bbe9de119f1aa11f7ca41a5f.
