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 Anthony _______________________________________________ Kamailio (SER) - Users Mailing List firstname.lastname@example.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
