From the article: http://www.webrtc.org/faq "Includes and abstracts key NAT and firewall traversal technology using STUN, ICE, TURN, RTP-over-TCP and support for proxies."
And the heavy lifter here is TURN. Go read about that. It does EXACTLY what I said it does. Man in the Middle.
But STUN is not. TURN is the last resource, nobody wants clients to use it, as it is expensive.
Google probably uses excess bandwidth all over the world to supply TURN servers, just like every sip provider has been doing for years.
NOT every SIP provider, only some of the heavy ones. Many only provide signaling and addressing. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
