What the Features Do
Here are brief descriptions of 23 voice features, including what each one does and how
you might want to use it. You will have the Conference, Drop, Hold, Message, Mute,
Redial, Select Ring, Self-Test, and Transfer features. In addition, you may have many of
the other features listed here; your System Manager can advise you.
Abbreviated Dialing Allows you to store selected telephone numbers as 3 digits or
less for quick and easy dialing. Each number can be a complete or partial telephone
number, an extension number, or a trunk or feature code. There are 3 possible types of
lists—personal, group, and system —and you can have a total of 3 lists. Numbers on a
personal list are programmable by you; numbers on all other lists are programmable
only by the System Manager. Use as a timesaver for dialing frequently called, lengthy,
or emergency numbers. Note: Check with your System Manager concerning what
types of lists you have and how many of each.
Automatic Callback Sends you a special 3-burst ring tone indicating that a
previously busy extension is now available. Use to avoid constant redialing when you
wish to speak to someone who is frequently busy on the telephone. Note: Can be
used only for extensions, not outside numbers.

Bridging Permits you to answer or join in calls to someone else’s extension by
pressing a bridged appearance button on your terminal. This button can be any call
appearance button labeled with another user’s primary extension number, as assigned
to you by your System Manager. Use to assist in handling calls for a designated
co-worker.
Call Coverage Provides automatic redirection of certain calls to your terminal for
answering. (Your System Manager determines which calls will be sent to you.) Use to
answer calls for other extensions for whom you provide coverage.
Call Forwarding All Calls Temporarily forwards all your calls to another extension
or to an outside number, depending on your system. Use when you will be away from
your voice terminal and you want your calls to be forwarded to a telephone number of
your choice.
Call Park Puts a call on hold at your voice terminal, for retrieval at any extension.
Use when you need to go elsewhere to get information during a call, or whenever you
wish to continue a call from a different location. Also, if the call received is for
someone else, use it to hold the call until the called party can answer it from the
nearest available telephone.
Call Pickup Lets you answer a call at your voice terminal for another extension in
your pickup group. Use when you wish to handle a call for a group member who is
absent or otherwise unable to answer. Note: You can only use this feature if you and
the called party have been assigned to the same pickup group by your System
Manager.
