Maybe I've not explained this correctly. I know, or can look up, the 40+ 
local exchanges that are local. I can parse the dial EXTEN to determine 
the exchange. I can check the exchange against a DB. I want to determine 
which exchanges are "local". I do not want to store an exchange dialed 
by a user.

How can I store a lot of 3 digit numbers which I then can check against 
an EXTEN to determine a local number?
