What type of data protocol is inside ChannelData when webrtc completely uses turn relay? Does not look like SRTP;
The ChannelData
messages will contain all the messages you would see on a non-TURN WebRTC call. The WebRTC Agent sends the same messages as usual. Only the ICE Agent is aware that it is communicating via TURN.
Inside the ChannelData messages you will have STUN
(Used by ICE) DTLS
and SRTP
.
