Hi there, Has anyone experienced any problems using TURN/STUN on the mobile telephone network? I'm using the test TURN server and a TURN client, but the behaviour seems to be a bit erratic on the cellphone network, sometimes it works, other times it doesn't.... I don't know if this is a problem with my application, or whether it is something that the network operator may be doing? Also, would it make a difference if I set it up using UDP or TCP (at the moment I'm using UDP)? Many thanks, Michael
