Connection using the TURN server

When you create a session using the Flashphoner API you need to pass the mediaOptions parameter where the coordinates of the TURN server are specified. Below is an example of creating such a session:

Flashphoner.createSession({urlServer: url, mediaOptions: {"iceServers": [ { 'url': 'turn:192.168.0.1:3478?transport=tcp', 'credential': 'password1', 'username': 'username1' } ], "iceTransportPolicy": "relay"}})

Known issues

1) The Microsoft Edge browser does not play streams via the TURN server

Solution: use another browser, because Microsoft Edge does not support TURN via TCP
