Understand Extension and how to remove parts of incoming number and check database

Which other thread? I don’t understand.

Catching different prefixes, remove part of them and search in database

Currently, it’s simple configuration. I have sip users saved in table sipfriends. The goal is on an incoming call to check if prefix exists. If exists - remove it and look into the table for that number.

(I hadn’t realised it was two different people; I’d assumed it was one person, inappropriately, starting multiple threads.)
