Hello Kamailio-Users

I'm using kamailio 5.1 with Alias_DB module. My subscribers register with a username like 0000001, 0000002 etc...
Every user has a list of multiple aliases which they can use on their SIP-Trunk.
I want to avoid that the user can use any alias for outgoing calls, only the aliases which are boud to his username in the aliases-db.
So, if the user uses an alias which does not belong to him, i want to overwrite it to the first alias for his username in the aliases-db.
At the moment, the function alias_db_find returns me the last alias found in the db.

Is there any way to do it? Or is there a way to extend the dbaliases with a new column marking the "primary" alias for an account? This would be the perfect solution.

Regards
Stefan
