but not in this: [UA] <-- [KAMAILIO] <-- [IP-PBX ] because Kamailio is not keeping the location of the UA.
I want to register UA's on Kamailio, but the authentication is done by [IP-PBX]... So Kamailio as Outbound Proxy + Location Server ... any idea on how I can achieve this configuration?
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?
