Hello,
registered() takes the r-uri as (hidden) parameter, but it has to be the
AoR, not the contact, otherwise will fail. If you use usrloc with mode 1
or 3, then you can use avp_db_query() to do a select against location
table -- see the avpops module documentation.
However, this might be a risk, because spoofing SIP messages is quite
simple. I would suggest at least to check the source IP and port as well.
Cheers,
Daniel

Hi,
I want to tweak my openser setup so it allows calls (INVITES) only
from registered contacts.
I was wondering if there is a way to check the received contact in the
invite message against the location table in mysql database, where i
store the registered users.
I do not want to make additional digest authorization of the Invites.
I see that the registered() function in registrar module has something
like that, but it makes the check on the request uri, not the contact.
Also if someone can think of a better way to allow calls only from
registered contacts I would greatly appreciate any tips.
Thanks.
Best,
D.
