Hi!

I have some challenges with alias_db_lookup and hope someone here can help.

I have a PBX that has registered 111@xxx with my OpenSER. I want to attach 222@xxx and 333@xxx to that registration and alias_db_lookup does that fine.

If a call comes to 111 the sip header looks like this

INVITE 111@xxx .... To: 111 111@xxx ...

And everything works fine.

But if a call comes to 222 the sip header looks like this:

INVITE 111@xxx .... To: 222 222@xxx ...

But now the PBX thinks that the call is for 111 and not 222.

On Asterisk I can do something like this to solve the problem:

exten => _X.,1,goto(from-siptrunk,${CUT(CUT(SIP_HEADER(To),@,1),:,2)},1) [from-siptrunk] exten => 111,1,dial(SIP/1010) exten => 222,1,dial(SIP/1020)

But a lot of SIP enabled PBX's cannot do that sort of thing.

One solution is the force the PBX to register with OpenSER for every number, but I would prefer not to do that. Another solution is to manually populate the alias tables but this is not very elegant.
