I am currently working on a project which requires me to use Asterisk as an IP-PBX and have a seperate SIP Registrar. I was wondering as to how to set up the architecture for this. Here are my questions:
1- Is it possible for Asterisk to forward SIP registrations to the registrar? (not have Asterisk register, but the clients)
2- Can this be done using OpenSER as a registrar solution?
I may have misunderstood a number of things, but here is my brainstorming of possible setups so far (illustrating registration):
option A: Client <-> Asterisk <-> Registrar
option B: Client <-> Registrar <-> Asterisk
My only issue with option B is that it will have to route all calls to the Asterisk IP-PBX, and will have to be scaled as such, whereas in option A it can be scaled to a minimum.
Thanks in advance!
