I am using the websocket version of this app, I have my own heroku server up and everything works however I see in your code you are referencing this:
var url = 'https://service.xirsys.com/ice';
Why is this being referenced? It is causing problems with my solution and I don't want to have my code referencing anything that isn't on one of my servers.
Can you assist in explaining why there is this url in the code when I already changed my signaling server path in ui.peer-connection.js
Your code in the console also shows to be using https://webrtcexperiment-webrtc.netdna-ssl.com/getIceServers/
Why do you have that referenced in here??
