I have written a webrtc client in which re-negotiation(re-offer/answer) is required after call gets established. Scenarios such as 1) upgrade calls from audio to video 2)Downgrade call from video to audio 3)Hold the established call 4) Retrieve the held call

I see mozilla/firefox has issues with re-negotiation of SDP( it fails in setting remote description). Any idea why is this a constraint in Mozilla and has no issues with Chrome.

Are you taking about the state change?: https://developer.mozilla.org/en-US/d.../RTCPeerConnection.onsignalingstatechange

Are you establishing a new connection then tearing down the old one as renegotiating, or are you reusing the existing stream? [Bug 834038 - SDP renegotiation should re-use existing streams when possible]

Yes, I was referring to statechange. I am re-using the same stream on same peerconnection object.

Problem still persists.
