The Integration of WebRTC and SIP: Way of enhancing real-time, interactive multimedia communication
“WebRTC won’t replace the existing legacy VoIP infrastructure but the application will provide real-time peer-to-peer video and voice communication where the standard carrier network isn’t capable”.
To make you understand how WebRTC and SIP together are used pretty great here’s some application that enhances the WebRTC and SIP technology to deliver some great applications used by millions.
We used this technology for our product Viyo (viyo.io) :) check it out if you want to see some real world usage of it.
We've been using WebRTC in an "off-label" way for Push-To-Talk communications in groups of arbitrary size. It's nice to be able to have it just-work in any browser with no downloads--even on a mobile browser. There's a lot of resistance to downloading apps these days, so being appless with WebRTC is a big help.

And we'd love to talk WebRTC with other developers in this space.
