AT&T Generic 1 - Manual (Page 15)

Call Waiting When you are busy on a call, sends a distinctive tone to notify you of
another incoming call waiting to be answered. This allows you to complete or hold
your present call and pick up the waiting call. It will save you from missing calls,
and your waiting caller from having to call back later.
Conference Allows you to add a third party to a call, so that you can conduct a
three-way conversation. (If you wish to conference more than three parties, call your
attendant for assistance. ) Use to set up time-saving conferences, or to spontaneously
include a third party important to a discussion. Note: If you have both an active
call and a call on hold, you must terminate one of them before you can use
Conference.
Drop Allows you to drop a line without hanging up the handset or turning the
telephone off.
Hold (with Second Dial Tone) Puts a call on hold until you can return to it. When
you hear a second dial tone, you can place or answer another call or activate another
feature. Use the Hold feature when you have a call you don’t wish to drop, but which
you have to interrupt briefly to do something else.
Leave Word Calling Leaves a message for another extension to call you back. The
called party will be able to dial message service (for example, attendant, AUDIX®,
covering user, etc.) to retrieve a short, standard message which gives your name and
extension, the date and time you called, and the number of times you called. Use
any time you wish to have someone call you back; it will help cut down on repeated
call attempts.
Priority Calling Allows you to call another extension with a distinctive 3-burst ring
to indicate that your call requires immediate attention. Use when you have
important or timely information for someone.
Send All Calls Temporarily sends all your calls to the extension of a person
designated to answer them when you cannot (perhaps a secretary or receptionist).
Use when you will be away from your desk for awhile, or when you do not wish to be
interrupted by telephone calls.
Transfer Transfers a call from your telephone to another extension or outside
number. Use when your caller needs to speak further with someone else.
Note: Calls from an outside number to your telephone can be transferred only to an
extension, not to another outside number.
Voice Message Retrieval Gives you messages (via computerized voice) left for you
through Leave Word Calling or as typed by a covering user. If authorized by your
system manager, you may also retrieve messages for one or more of your coworkers.
Use to hear all messages received while you were away.
