use the CLASSIC MAIL System.
Know Your Phone
Using the CLASSIC MAIL system is a simple matter of using
a touch-tone phone. You press various keys to gain access
to your mailbox, use its functions, and move around in the
system.
Before you use your mailbox, you should know that an
operator or receptionist is called an attendant and a phone
extension is called an intercom.
