Based on conversations in MMUSIC, as well as several offline conversations with interested parties, I've put together a proposed change to JSEP that, if accepted, will allow publication of the Cluster 238 documents to move forward. Note that this new text has no impact on existing implementations (at least, as far as I am able to discern), which do not currently have the capability of producing media sections consisting of exclusively TCP candidates. From that perspective, the change makes existing implementations no less compliant with JSEP than they were before. What this change does provide is both on-paper and in-the-future compatibility between WebRTC implementations once they finalize TCP candidate handling (and candidate handling in general for mid-session offers). https://github.com/rtcweb-wg/jsep/pull/862/files The key insight here is that JSEP's use of ICE completely discards any meaning associated with the transport parameter, while SIP's use of ICE does not. The trivial change that I propose, which bears only on future WebRTC implementations -- that is, which has no as-built specification to point to -- allows JSEP to continue to ignore the value of the transport parameter, while specifying that it says the right thing for SIP implementations to function properly. /a
