This will modify and cause a renegotiation of an in-progress WebRTC session. This can be used to change the active media lines and activate a Push-To-Talk connection that was not originally requested in Get Live WebRTC Offer. Note that the SDP
sess-version field must be incremented properly.
To terminate a WebRTC session use Stop Live WebRTC.
Note: A renegotiation can not change the
iceTransportPolicy from the original Offer/Answer exchange.
