AT&T® Centrex Service

Centrex also makes it easier for the outside world to do business with you. With AT&T® Centrex, local and long distance calls flow directly to a specific individual or department. Your customers and suppliers will have direct telephone access to the employees they want .
Flexibility is always built into your Centrex system, giving you the option of having calls directed to a central attendant or voice mailbox.
