pay attention, you MUST use the "transport" argument for tcp to work, eg:

turnServers: {
  urls:"turn:exam.org:443?transport=tcp",
  username:"alice",
  password:"racecar"
}

Take a look at coturn, a fork of rfc5766-turn-server, which supports RFC6062, the TCP transport for TURN.

Hi All,

I have one problem.
One of my clients is behind the serious firewall and they are banned UDP connection at all. His clients are connected to it via the Internet.
I put my own Turn/Stun server (rfc5766-turn-server from Google). It works the same server as the freeswitch. It works fine.
The problem follows. When all banned UDP connection - you can not connect (INCOMPATIBLE_DESTINATION). If you allow outgoing UDP At least, that is connected with no problems.
Is it even possible connection if one of the parties completely banned UDP connection?

I thought that the problem is just the decides the turn server. But I is not working for me.
