Now that WebRTC is now live in Chrome version 23, which is now rolling out to the public, expect some new exciting web applications with audio and video that will change the way we communicate beyond what we have seen so far with Skype and Flash.
The SIP community have already forged ahead with SIP over WebSockets and a number of SIP signaling libraries have started to appear. I am not convinced that employing heavy bloated SIP messages for WebRTC signaling is the best approach, but I am not ready to re-open an ancient debate.
To try it out, you would need two PCs with webcams both running latest Chrome version 23+. Use any two unique user names (eg user1 and user2) with no spaces and special characters. From user1, enter contact JID to call as email@example.com/user2 or vice-versa.
