Abstract
An automatic access code dialer stores a user entered telephone number and compares the first three digits of the stored telephone number to a list of three digit numbers that specify telephone exchanges that may be contacted using an alternative shorthaul long distance service provider. If the stored digits match one of the numbers on the list, the user entered telephone number and an access code for a alternative service provider are passed to the telephone network. If the stored digits do not match one of the numbers on the list, the user entered telephone number is passed to the telephone network.
