Hi TuanND, <snip> b) Browser application interacts with VoIP server (use HTTP) browser<------>RTCweb server & SIP client (new GW)<------>SIP server New Gateway is outside the scope of RTCWeb and IETF which provides the opportunity for innovative way of building gateways but may leads to interop issue due to mapping between RTCWebserver & SIP client w.r.t mid-call services. </snip> The issue in case webserver acts as new RTCWEB & SIP GW for VoIP communication, there is a need of protocol mapping between the protocol used between browser & RTCWebserver (say RTCweb protocol) to SIP. In my experience with signaling protocol interworking, the interop between two vendors fails lot of times in mid-call services like Hold, resume, transfer and IETF BLISS WG is good example for such failures. My question was why RTCWeb was looking into that approach. >From http://www.ietf.org/mail-archive/web/rtcweb/current/msg00730.html mail thread, I understand that more discussion will occur in RTCWeb to clarify this doubt. Please let me know in case you need more explanation.
