Looking at the documentation it seems that as long as I have a line like listen=tcp:10.30.0.55:3339 <http://10.30.0.55:3339/> I should be able to force an outbound connection to originate from that host and port, i.e. to establish a persistent connection from a specific socket to a remote host, but having tried to set it via $fs and set_send_socket() it always uses an ephemeral port. Ideally I would like kamailio to use a specific source port for contacting a specific remote host and keep the TCP socket established, and it seems like it should be simple enough to do but it's not working as expected.
