I'm talking about the source port, not the destination.

My expectation is for Kamailio to use a random kernel-assigned source 
port, just like everybody else who opens a TCP connection.

How do you expect two Kamailio processes to talk to each other if they 
both decide to connect to the other side simultaneously? This works with 
"normal" TCP, by design, but AFAIK the TLS layer has a strict 
client/server separation and thus can't do that.
