When an outgoing TCP connection is opened, either a port can be
explicitly bound, or it is auto-assigned by the OS's networking stack. I
believe Kamailio does the latter and does not offer options to constrain
the range. If it does, I'm not aware of any apart from this one:

Not sure if it would help in this case, you'd have to give it a try.

It appears that the bottom line of my TCP transport
not working is that Kamailio is randomly assigning large port numbers to send the TCP
traffic out on.
I am not able to randomly open high ports for this purpose. Is there a way to tell
Kamailio to only use specific ports for this. I have tried using
force_send_socket() with Kamailio' s IP, and the port I want to send out on, but this
did not work either. Does this sound like I am on the right track?
Thank you,
