You use relay, you speak TCP to the relay and it turns it into UDP, FreeSWITCH is oblivious that its even taking place. On Wed, Apr 29, 2020 at 5:34 PM David P <davidswalkabout@gmail.com> wrote:

Hey Brian,
Your tip about include_external_ip seemed relevant to my recent question whether FS supports TURN TCP; that is, can FS be configured to provide a tcp candidate in its answer sdp, which would save the cost of sending calls through TURN for users whose firewalls block needed udp ports.
I searched for your variable in the source and found
https://github.com/signalwire/freeswitch/blob/53cd06900c5ce827b2c0ac74485607... which shows that the transport is not frozen as "udp" but is the value of ice_out->cands[0][0].transport
Is it possible for this transport member to be "tcp"? How could one configure FS to provide both udp and tcp candidates?
