I didn't know that. But all of this is moot. My router also modifies
the Via "received" parameter, so that when it receives response with
it's public IP in the "received" parameter, it will modify it and put
my private IP in it. Sigh.. The only way to stop the router from
messing about with SIP messages is to change the server to not use
port 5060.
