Use Path mechanism so Kamailio would add a "Path" header in the
REGISTER before relaying it to the PBX. But the PBX MUST support Path
mechanism (RFC 3327).

Anyhow, for sure you would do much better by making Kamailio also
acting as a registrar. Why do you need the PBX to be the registrar?

Yes I want to make it as a register but I don't want to store authentication information in the kamailio.
So any REGISTER request is forwarded to the PBX.

Is it possible to do this in kamailio?
