This is fine, and you can make your outbound calls in that fashion. You do
need to have Asterisk present enough information that Kamailio is aware of
how to route that outbound INVITE request, but if you have sufficient
information in the request URI, it can certainly make that decision.
If, however, you wanted to dial PJSIP/1000 - which no other information and
where 1000 is some registered device - Asterisk will need the registered
contact that the device has presented to the registrar. In which case, you
have to have some mechanism for Asterisk to get at that information.

Yup - it all depends on how you configure / use things.
