My interpretation of your draft is that it is a description of how you can deploy SIP implemented in JS over websocket. Thus enabling SIP interworking when needed by having the JS SIP stack convert regular SIP with SDP into interactions with the WEBRTC API. Thus your proposal really is primarily an argument that you don't need SIP implemented in the browser, as long as the API allows the JS to create SIP with SDP messages. Thus I would interpret this as something that could work both over something similar to the current PeerConnection API proposals and a more low level API. Where PeerConnection likely is less work as it does provide the SDP that in most cases don't need modifications. Is this a correct interpretation and thus your draft is an extension that simplifies life for the people who like SIP interworking by getting the SIP functionality into the end-point rather than a gateway? Or is it something else? If it is the first I don't see your proposal as complete proposal for how signaling for RTCWEB, as you still need APIs to something in some form and with possibly certain semantics that interact with the SIP in JS implementation. To clarify, what I see the question for the WG is how the signalling model for RTCWEB session establishment is intended to work. Thus the drafts intended for answering this needs to be focused on describing a signalling model.
