Have a read about 'mhomed' works and see if it might make sense to turn it off or on:
https://www.kamailio.org/wiki/cookbooks/5.1.x/core#mhomed
Otherwise, for experimentation's sake, try mhomed=0 and force the outgoing listener explicitly:
$fs = 'tcp:x.x.x.x:5060';
...
t_relay();

Yes there is an error. I get this error trying both ways => no corresponding socket found for "111.25.1.99" af 2 (udp: 111.25.1.99:5060). It is still trying to send UDP. 111.25.1.99 is accepting TCP traffic, other calls are reaching via other sources using TCP.
I'm just not sure why it is refusing to send tcp.

Are there any errors in the logs suggestive of a failure to select an appropriate egress listener?

Hi Alex,
I tried your suggestion and everything is still going over UDP. I verified with tcpdump/wireshark and all SIP traffic is UDP.
Thank you, -Steve

Hi Steve,
Do you have a TCP listener from which the messages would be expected to egress?
Also, try use regular t_relay(), but beforehand do:
$ru = $ru + ";transport=TCP";

Hi All,
I was attempting to switch from UDP to TCP for relaying. I used t_relay_to_tcp() instead of t_relay() =>
if (!t_relay_to_tcp()) { sl_reply_error(); }
The problem is that I am still seeing the SIP messages as UDP on the Server that the messages are relayed to. Any Ideas?
Thank you, Steve
