Hello,
what UAC is there and what version of freeswitch you are using?
The UACs are based on PJSIP 2.7 and FreeSWITCH is 1.6.20.
I am using SDES (not DTLS) so I set:
rtpengine_manage("DTLS=off ICE=remove");
Now there are two changes:
1. SDP is changed from RTP/SAVP to UDP/TLS/RTP/SAVP. Since the UACs are not using
DTLS, the connection is dropped. When I set transport-protocol=RTP/SAVP it works.
I think DTLS/SDES is misdetected by the module.
2. After fixing transport=protocol I have a different problem with FreeSWITCH (conference
bridge).
I compare working SDP with non-working SDP. The only difference is two lines
a=setup:actpass
a=fingerprint:xxxxxxxxxxxxxxxxxxx
I do not know why rtpengine decided to add them in. In 5.1.1 they are not there, and in
5.1.2
they suddenly appeared. When I sniff the traffic I confirm that the UAC did not add those
lines and they definitely come back from rtpengine.
rtpengine is 6.0.1
Thanks
