[SR-Users] rport

[Daniel-Constantin Mierla]

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
