Are there any plans for Twilio to integrate this with the SIP side of things (e.g. Twilio providing a media server to enable WebRTC clients to communicate with SIP clients and also call out to traditional phone clients?)
I wrote this http://www.siptowebrtc.com/ that uses our SIP interfaces and PSTN to connect to our WebRTC client. I'm going to put the code up on Github after I clean it up but I'd be happy to talk through how it works. andrew at twilio dot com.
