The following error is shown in the browser console
DOMException: Failed to set remote answer sdp: Session error code: ERROR_CONTENT.
Session error description: rtcpMuxPolicy is ‘require’, but media description does not contain ‘a=rtcp-mux’…
So I upgraded to Doubango SIPml5 v2.1.3 as per
To no avail, still no sound flowing even though rtcpMuxPolicy:“negotiate” is set.
FireFox works just fine.
WebRTC Chrome 57.0.2987.133 (64-bit), no sound in IVR using Doubango SIPml5 v2.1.3 Asterisk 13.15.0.
WebRTC FireFox ESR 52.0(64-bit), sound OK in IVR using Doubango SIPml5 v2.1.3 Asterisk 13.15.0.
Doubango SIPml5 v2.1.3 sets rtcpMuxPolicy:“negotiate”, so that should have fixed the problem, but still no sound in Chrome.
Any sugestions ?
