hmmhesays Posted July 10, 2018 Report Share Posted July 10, 2018 (edited) Anyone out there using libwebphone with the latest chrome? It requires RTCP-MUX but freeswitch doesn't seem to be sending that option back in the SDP DOMException: Failed to set remote answer sdp: The m= section:audio is invalid. RTCP-MUX is not enabled when it is required.

safarov Posted July 11, 2018 Report Share Posted July 11, 2018 I think root if issue is broken DTLS encription on FreeSwitch side when RTCP-MUX is disabled. You can try fix thishttps://freeswitch.org/jira/browse/FS-10981 Link to comment Share on other sites More sharing options...
