I'm not familiar with the details of JSEP, but on general architectural principles, my suspicion is that the key regarding interworking with SIP is not whether a JSEP-using application can send offers at times that the 3264 offer/answer model forbids it, but rather whether JSEP/WebRTC can *reject* an offer. Certainly in SIP, a new offer presented in a re-INVITE or UPDATE request can be rejected by the other UA by returning a failure response. Any WebRTC protocol that can interwork smoothly with SIP will require this capability. Given that, if the JSEP model permits an application to send offers at times when SIP does not, the WebRTC/SIP gateway/server can immediately send rejection of such offers back to the client, without sending a SIP request containing the offer. This approach tolerates considerable difference between the rules enforced by JSEP and the rules enforced by SIP, which may be convenient. Dale
