That was my experience with it. However, I was trying to use the native android build, and I believe the browser version is much better about that stuff.
I looked into WebRTC for a few days and had the same issues with the docs you folks mentioned. What is up with that? My sense was that WebRTC is just a repackaging of many existing standards so it isn't a new tech by itself. The challenge some of us are having is that we are not familiar with each of the underlying technologies. I felt I should revise SIP, and NAT traversals before I have a hope of cracking WebRTC.
