> The problem is that JSEP proposes to use UDP protocol in the m= line and at the same time update address and port to the currently selected candidate. Based on ice-sip-sdp, if protocol of the current selected candidate does not match protocol in the m= line, this will mean either ICE mismatch or additional candidate with protocol, address, and port form m= and c= line.

We could just assume that no WebRTC capable endpoint will (absolutely
never) rely on the content of the c= line or the proto indicated in
the m= line (no matter it indicates "CHICKEN" as proto).
