Yes, you need some functionality on the signaling plane to adopt the two worlds. I don't think it is that complex. The SIP GW may in fact be the Webapp itself that has a JS SIP stack and a bit of logic around that. It can also be in the webserver, or third signalling GW node that are connected to the webserver for the RTCWEB service. I think all of these cases works. Thus no need for standardizing the gateway function.
