If the system has access to multiple telephone companies, access to
a specific company requires a carrier code before the telephone
number. Toll Restriction for these calls is activated by storing the
carrier codes (maximum 20). If a stored carrier code is found in the
dialed number, a toll restriction check starts with the subsequent
telephone numbers.
