Hi all; I am investigating about how Centrex work with SIP. If an enterprise customer has a 2 different locations, how they call each other with short numbers(4 digit) ? Which SIP headers are used for it? Is there a standartization ? Does any one have a solution documentation? How the big companies handle it?
