[SR-Users] rport

[Marc Soda]

I'm rewriting the Contact header in the REGISTER to be Kamailio on port
5060.  For some reason Asterisk is sending INVITEs on the source port of
the message and not 5060.  I thought rport would correct that, but it
sounds like rport is only intended to for subsequent messages in a given
transaction...
