AT&T Classic Mail Voice Messaging System User Manual page 45

If the CLASSIC MAIL system reaches your
pager, it displays the number you've specified
to call to check your messages. If the CLASSIC
MAIL system reaches you at a phone number,
a recorded voice says there is a new message
for you and you press any key and open your
mailbox to listen to the message. After listen-
ing, you can proceed with regular message
disposition.
If another message arrives, the CLASSIC MAIL
system alerts you again.
If the CLASSIC MAIL system cannot reach you
at the specified numbers, it will leave a
message in your mailbox telling you of its
attempts. This message will be automatically
deleted once you listen to it.
Telling the CLASSIC MAIL system which phone or pager
to call can be as simple as entering a seven-digit number;
however, sometimes your off-site number will require an
additional prefix or an area code.
