Hello,
rport and Via headers are used for routing the SIP responses back to the device sending the request. They are not used at all for routing INVITE requests.
The tutorial you refer to is generating a new REGISTER from Kamailio to Asterisk, putting in it the Contact header with the address of kamailio. So Asterisk should send the INVITE to kamailio.
Cheers, Daniel

Basically, I'm trying to get Asterisk to send all future INVITEs to Kamailio on port 5060 and not the source port of the REGISTER. My REGISTER looks like this:
U 1.1.1.1:59738 http://1.1.1.1:59738 -> 2.2.2.2:5060 http://2.2.2.2:5060 REGISTER sip:2.2.2.2:5060 http://2.2.2.2:5060 SIP/2.0. Via: SIP/2.0/UDP 1.1.1.1:5060;branch=z9hG4bK404.05c2e5a7.0.

Subsequant INVITEs are sent to 1.1.1.1:59738 http://1.1.1.1:59738 and not 1.1.1.1:5060 http://1.1.1.1:5060. I need them to go to 1.1.1.1:5060 http://1.1.1.1:5060.

I have a Kamailio server forwarding REGISTERs to an Asterisk box, similar to the way Daniel shows here: http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb Can I force Kamailio to append rport=5060 to the topmost Via header, prior to forwarding the REGISTER to Asterisk? I tried add_local_rport() but it only included 'rport' and not 5060. Thanks, Marc
