Possibly the network isn't very good, possibly it had to relay us to holepunch. I might fork the code and make some kind of indicator showing if the connection is direct or not.

after closing a call I kept hearing you, so I imagine my play back got way behind somehow, local buffering or bandwidth
I'm compiling with relay disabled. I'm curious if will connect directly to my IPv6 and not need relaying.
