[Freeswitch-users] Registration VIA TCP

[Mitch Capper]

Rob this is related to FS-3877 (Reuse TCP connection for both
directions)  freeswitch will attempt to establish a TCP connection
back to the sip phone when sending it that incoming call and that is
not working causing the failure would be the best guess.    Ensuring
the proper contact port may allow it to reuse this connection and not
try to create this reverse connect, but otherwise ensuring the FS
server can properly connect back to the client will probably solve it.
Crank sofia loglevel should show the exact issue.
