Your 7406 Plus Voice Terminal

The 7406 Plus voice terminal is available in two models: one with a display and one
without. The display offers some added functionality, but both models are

What the Features Do

Here are brief descriptions of 31 features, including what each one does and how you
might want to use it. The first 24 are voice features and the final 7 are display
features. Note: You will automatically have the following features on your voice
terminal: Conference, Drop, Hold, Message, Mute, the Select Button, Select Ring,
Self-Test, and Transfer voice features and Normal mode among the display features.
You may also be able to use the Speakerphone (and Reset Speakerphone) or the
Speaker feature. Check with your System Manager to see what other features you
can use with the DEFINITY Generic 1 or Generic 3 or the System 75 switch.

Voice Features

Abbreviated Dialing (AD) Allows you to store selected phone numbers for quick

and easy dialing. Each of these numbers can be a complete or partial phone number,
an extension number, or a trunk or feature code. There are 4 possible types of
lists—personal, group, system, and enhanced—and you can have a total of 3 out of
the 4 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.

Automatic Callback Sends you a special 3-burst ring indicating that a previously
busy or unanswered extension is now available. Use to avoid constant redialing
when you wish to speak to someone who is frequently busy on the telephone or in
and out of the office. 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 voice 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 voice
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.
Note: If you have Go to Cover, you (the calling party) can send internal calls
directly to coverage any time during the call attempt (the person you call must be in
a call coverage group).

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 phone 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 complete 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 voice terminal.

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.

4

Conference Allows you to add parties to a call, so that you can conduct up to a
6-way conversation. (If you wish to conference more than 6 parties, call your
attendant for assistance.) Use to set up time-saving conferences, or to spontaneously
include a party important to a discussion.

Drop Disconnects from a call without requiring you to hang up the handset or
press the switchhook. Can also be used with the Conference feature to disconnect
the last party added. Use whenever you are using the built-in speaker instead of the
handset, or whenever you are using the handset and want to continue using it for
another action after ending a call.

Hold Puts a call on hold until you can return to it. While a call is on hold, you can
place another call, activate another feature, answer a waiting call, or leave your
voice terminal to perform another task. Use when you have a call that you don’t
wish to drop, but which you have to interrupt briefly to do something else.

Intercom (Automatic/Dial) Gives you quick access to specified extensions. With
Automatic Intercom, you can call a predetermined partner by pressing a single
feature button. With Dial Intercom, you can call any member of a predetermined
group of users by pressing a feature button and then dialing the group member’s
2- or 3-digit code. Use to rapidly dial frequently called numbers.

Last Number Dialed Automatically redials the last number you dialed, either an
extension or an outside number. Use to save time in redialing a busy or unanswered
number.

Leave Word Calling (LWC) 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.

Message Your Message light goes on when a caller has left a message for you. You
can then follow your System Manager’s local message retrieval procedures to get
your message. Note: If you have a display, see Message Retrieval under the
Display Features heading that follows.

Mute Turns off the microphone of the built-in speakerphone or the handset. Use
when you want to confer with someone in the room with you, but you do not want the
other party on the call to hear your conversation.

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.
Reset Speakerphone Initiates an acoustic test of the surrounding environment by

using a series of tones. When the tones stop, your speakerphone has finished
adjusting itself for optimal performance. It is now ready for use. Use whenever you

5

move your voice terminal to a different location (even in the same room), or
whenever the light next to [

Speaker Reset Spkr

] is fluttering. (For best results, use the

Reset Speakerphone feature when the handset is on-hook.)
Select Button Used in any of 4 ways:

1) When used with a feature button, you can access the top-labeled feature on 2-level
buttons. Use whenever you need to access one of these top-labeled features.

2) When used with [

Drop Test

] , you can perform a self-test of your voice terminal’s

lights, ringer, and display.

3) When used with [

Conference Ring

] , you can select your own personalized ring from among
8 available patterns. Use to distinguish your ring from that of other nearby voice
terminals.

4) When used with [

Speaker Reset Spkr

] , the built-in speakerphone performs an acoustic test

of the surrounding acoustic environment to provide optimal speakerphone
performance. Use whenever you move your voice terminal to a different location
(even in the same room).

Self-Test Initiates a test of the lights, ringer, and display on your voice terminal.
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 phone calls.

Speaker Allows you to place calls or access other voice features without lifting the
handset. However, in order to speak to the other party, you must use the handset

(the speaker must be off). Use with feature activities that require listening only,
such as on-hook dialing, monitoring calls on hold, and group listening situations.

Note: Your voice terminal has either the Speaker (listen-only) or the Speakerphone
function. Check with the System Manager to see how your voice terminal is set.

Speakerphone Allows you to place and answer calls or access other voice features
without lifting the handset. When [

Speaker Reset Spkr

] is used with [

Select

] , the built-in
speakerphone performs a test of the surrounding acoustic environment and adjusts
itself for optimal performance. (See Reset Speakerphone.) Use the built-in
speakerphone any time you prefer hands-free communication, both speaking and
listening, or for group conference situations. Note: Your voice terminal may be set
for the Speaker (listen-only) rather than the Speakerphone (listen and speak)
feature. Check with your System Manager.

Transfer Transfers a call from your voice terminal 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 voice terminal 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 entered by a covering user. If authorized by your
System Manager, you may also retrieve messages for one or more of your co-workers.
Use to hear all messages received while you were away.

Display Features

Inspect Shows you call-related information for an incoming call when you are

already active on a call. Use to identify and screen new calls.

Integrated Directory Searches for the extension of another user by allowing you to
key in the user’s name with the dial pad. Use as a handy quick reference source for
extension number information.

Message Retrieval Allows you to retrieve messages left for you that have turned on
your Message light. Will also let you retrieve messages for other voice terminals not
equipped with a display (if you are authorized as a systemwide message retriever by
your System Manager). Use to quickly and conveniently check messages, even when
you are already on a call.

Normal Identifies current call appearance, calling/called party, and calling/called

number. Use to see who is calling you and, when placing a call, to verify the number
you have dialed.

Stored Number Allows you to check the number stored on an Abbreviated Dialing
button or as an item on an Abbreviated Dialing list. Also lets you see what number
you last dialed (via Last Number Dialed feature). Use to verify Abbreviated Dialing
list items before placing a call or reprogramming a number, and to make sure that
Last Number Dialed is appropriate to use.

Time/Date Shows you the date and time. Use as a handy calendar and clock.

Timer Allows you to measure elapsed time. Use in order to keep track of time

spent on a call or task.

How to Use the Features

The procedures which follow give short, step-by-step instructions for using each of
the voice features and display features. For your convenience, features in both
categories are listed alphabetically.

Special Instructions

The first time you use these procedures, you will need to customize them for yourself
by following the directions below. Your System Manager can supply the information
required.

●

To the right of each feature name is a box. For each feature that you have,
mark a [
Drop, Hold, Mute, Message, the Select Button, Select Ring, Self-Test, and

System Manager if your voice terminal is set for the Speaker (listen-only) or
the Speakerphone (speak and listen) feature, and then place a check in the box
beside that feature also. Note: If your voice terminal is set for the
Speakerphone feature, you can also put a check in the box beside the Reset
Speakerphone feature.

●

Most of the voice features can be activated or canceled by dialing 2- or 3-digit
codes (if they are not already assigned to a button). In the blanks provided
within the procedures, write in the feature code numbers.

complete a procedural step or have made a dialing error. Hang up, get dial

tone, and begin again at Step 1.

●

System 75 is available in more than one version. Some features, such as
Abbreviated Dialing, Call Forwarding All Calls, Last Number Dialed, and
Priority Calling operate slightly differently with Version 1, and possibly
Version 2, than they do with later versions. If you are using Version 1 or 2 of
the System 75 software, you should check the section titled Troubleshooting
