WG, This is an attempt of me as WG chair to try to summarize the state of the discussion as it was when I wrote this. As usual please speak up against any miss-characterization of the state from my side. The Chairs request for identifying who like to provide input for a signaling discussion two weeks and to follow up this with a Internet draft has resulted in that we now have two drafts. a) RTCWeb Offer/Answer Protocol (ROAP) https://datatracker.ietf.org/doc/draft-jennings-rtcweb-signaling/ b) RTCWeb standard signaling protocol https://datatracker.ietf.org/doc/draft-partha-rtcweb-signaling/ We also have a third proposal that want to be included in the considerations: c) RTCWEB does not define any signaling behavior at all, instead W3C is tasked to develop an API that allows the application to establish the media session between peers. I have as WG chair requested that the proponents for C to produce a Internet draft that provides requirements on the API and its capability. This is to ensure that this proposal can be properly evaluated. So far no such contribution has occurred. Without a willingness from the proponents of this style of solution to contribute and evolve their thinking in such way that the other WG members can gain a better understanding of the implications of this solution I find it difficult for us include it in the up coming consensus call. We intended to have a phone conference on Friday to enable some direct discussion on the topic of signaling between the WG members. Details to follow. This is not an interim, only a possibility for the WG members to further their understanding in preparation for the decision. In addition to signaling proposals the WG have received two other I-Ds. 1) Real-Time Web Communication Simplified Interconnection https://datatracker.ietf.org/doc/draft-beck-rtcweb-alt-ic/ Which I interpret as a discussion piece around the federation and interconnect usages. 2) WebSocket Transport for Session Initiation Protocol (SIP) https://datatracker.ietf.org/doc/draft-ibc-rtcweb-sip-websocket/ This is a demonstration that SIP could be implemented in Java script and be transported over web-socket to enable the cases where SIP want to be used between a browser instance and a SIP system and its user agents. This has some requirements on the API to either provide SDP in O/A style or something that enables the SIP stack to create SIP messages with SDP O/A messages. There has been lively discussion around these documents which I hope continues but it does need to come to some conclusions.
