SDP OK. At point of time now, I prefer SIP to Verto as Webrtc signaling as I am familiar with SIP. Well, can help to provide workable configuration. Or troubleshooting the issue. Thanks a lot. As understanding, CODEC NEGOTIATION DEAY is set, how does FS include SRTP-DTLS (UDP/TLS/RTP/SAVPF) in m line of SDP to be sent to Chrome endpoint. In my case, in the SDP sent from FS to 1010 (Chrome endpoint, Registered via WSS), there is no such information but normal RTP (RTP/SAVP). Coming back, the key issue is still CODEC NEGOTIATION ERR for WebRTC. Regards Smile.
