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

which shows that the transport is not frozen as "udp" but is the value of ice_out->cands[0][0].transport
