I have two problems.
1 - This only works with windows x windows chrome. If I test with ubuntu or mac with chrome, doesn´t work, I can login, but I call another user and stay the screen and call in process...
2 - In device, line var socket = io.connect('http://myserver.com:3000/'); I have this error :
"http://myserver.com:3000/socket.io/?EIO=3&transport=polling&t=1446506264545-0 Failed to load resource: the server responded with a status of 404 (Not Found)"
Not to discourage you from PhoneRTC but my team spent a lot of time working with it and after running into lots of issues we ended up using this cordova plugin instead: https://github.com/eface2face/cordova-plugin-iosrtc . It seems to be a more active project, exposes the standard WebRTC API and so far its worked really well for us. If you want to play with a sample of it in action you can go here: https://github.com/WASdev/sample.rtcomm.mobile
