Hi Andreas,
I guess you already use the uri_db module for checking with check_from()
the mapping between the SIP id and auth id (against DB).
If so, for the inbound part, the natural way will be to use the same
module (read : to extend the module) to allow you to retrieve the auth
Id from the table based on the SIP uri ($ru is better than $tu):
get_auth_id("$tu", "$avp(s:auth_user)","$avp(s:auth_realm)");
Regards,
Bogdan
