[SR-Users] registrar and check registered

Hello, Daniel. Thanks for reply.

In our scheme all calls forwards to PSTN GW, if that call from our to
our users, GW turn call back and kamailio receive it as incoming.
So, no "local calls" in this scheme. 

For outgoing calls (to PSTN) i want check caller (origin) is registered.
For incoming calls (from PSTN) i want callee is registered.

Need cache registrations (DB, memcached or something). I try that way:
1. REGISTER - if ok, than we save("location").
2. Other methods - check !registered("location") or !lookup("location").
But in INVITE seems both !registered("location")
and !lookup("location") return TRUE. I dont understand why. 

In topicstart letter i citate part of my cfg: in INVITE i check
registration again and it work - registered users may call to PSTN,
unregged may not. But no cache for registration and look as overhead.
Must be more "beauty" solution.
