Hello, according to the instructions on https://freeswitch.org/confluence/display/FREESWITCH/WebRTC I have enabled webrtc on one Sip profile. I’ve added my own cerificate and installed in /usr/local/freeswitch/certs. I’m connecting to freeswitch using JsSip library. The signaling part works fine, I can see all SIP messages in the log, but then it fails to establish the audio/rtp connection: 2014-11-10 17:36:27.065688 [INFO] switch_core_media.c:5206 Skipping RTCP ICE (Same as RTP) 2014-11-10 17:36:27.065688 [INFO] switch_rtp.c:3065 Activate RTP/RTCP audio DTLS client 2014-11-10 17:36:27.065688 [ERR] switch_rtp.c:3117 audio DTLS key err [1] I’m a bit confused about this message, I thought all tls settings in a sip profile and the dtls-srtp.pem certificate is not relevant for webrtc / wss, or what does this error message want to tell me? Thanks Markus
