No, I have 'force_rport()' in the script, but neither
'force_send_socket()' nor 'force_tcp_alias()' is there at
all. Are you suggesting that I use it before t_relay to the
server with a different transport?

Is the basic idea of this warning message that OpenSIPS
exchanges a SIP message with a UA over a certain transport
(TLS in this case) and port number (5061 in this case), but
a t_relay in the route script forwards the message over a
different transport or to a different port number?

If so, what is being compared and how is it compared?

  Port1 == Port2
  Transport1 == Transport2
  Transport1 & Port1 == Transport2 & Port2
  ...?

Thanks,
Brian
