+ 1 for using SIP over WebSocket.

Is there any reason you cannot use SIP over WebSocket (

Call signaling will require a lot more information then what is provided in JSEP. JSEP mostly deals with offer and answer processing. Signaling will also need to deal with things like who is calling, why they are calling, transfers, other application specific details. In other words, I think this is a very bad idea.

With websockets as a de-facto transport protocol for WebRTC signaling and JSEP being the format of encoding information, there is a need for a defining a websocket sub-protocol : jsep. So I would like to know if there is any interest in the community and also the views from experts about the need for a websocket-sub protocol for JSEP.

The main purpose of defining the sub protocol (jsep) is to make sure that the WebRTC client (WIC) and WebRTC server (E-CSCF) are receiving JSEP encoded messages.
