There's not really a reasonable way for you to add your own Via header to this outgoing request. If Kamailio is doing something wrong or inconsistent in this context, it should be fixed there.

Alex,
No dice.
So now my question is what is the correct way to fix the Via?
If this is the original:
Via: SIP/2.0/TCP 1.1.1.1;branch=z9hG4bKd408.3f53e940ccb20c1033df4b3a8ebd8a34.0;i=1
Then do I update the port like this:
Via: SIP/2.0/TCP 1.1.1.1:33940;branch=z9hG4bKd408.3f53e940ccb20c1033df4b3a8ebd8a34.0;i=1
Or should I use an rport tag:
Via: SIP/2.0/TCP 1.1.1.1;branch=z9hG4bKd408.3f53e940ccb20c1033df4b3a8ebd8a34.0;i=1;rport=33940
Thanks!

Noah,
It is also possible that this core config parameter will in and of itself cure your problem:

Not sure whether it helps only in tandem with the previous UAC default_socket modparam suggestion, or is sufficient in and of itself.
