The Telephone:
1. The Telephone
This guide covers the use of the 4620, 4621, 4625, 5620 and 5621 phones on IP Office phone system. These phones are
physically similar. The key difference is that the 5620 and 5621 are only supported on the IP Office where as the 4620,
4621 and 4625 are supported on a range of Avaya phone systems.
The diagram below shows the main phone features:
1. Display and Feature Buttons:
The Call Appearance Keys enable you to handle multiple calls with the display showing call information. There are 2
pages in the display; giving up to 24 system features that can be allocated to the function keys. See Call Appearance
9 44
Keys and Overview . The information displayed varies according to the active feature.
· The display of the 4621 and 5621 phones have a backlight, while the display of the 4625 has a color backlight
with built in standby mode. When in standby, lifting the handset or pressing PHONE/EXIT will re-activate
the display.
2. Message Waiting Lamp: This lamp is used as follows:
· On (Continuous): There are new messages in your voicemail mailbox, or in another mailbox for which you
have been configured to receive "Message Waiting Indication".
· Flashing: The lamp can also be set to flash when the phone receives a call. See Visual Alerting .
3. Page Right/Left:
Shifts from one page to another in the same application when the display presents the paging indicator ( ). These
buttons have no effect when the paging indicator is not displayed.
4. Options:
Displays the Options main screen, from which display and application settings can be updated.

6. Numeric (dialling) Pad:
Standard 12 button pad for dialling phone numbers.
7. Volume Controls:
Adjusts the handset, speaker, headset, or ringer volume, depending on which item is in use. As you increase or
decrease the volume, the top display area provides either a speaker, headset, handset, or ringer icon to indicate for
which item you are adjusting volume, followed by a visual “volume meter” showing the volume level. These buttons
also control the volume of the key click sounds made when you press fixed buttons on the phone, such as the dial
pad or softkeys.
8. MUTE and LED Indicator:
Turns off the active SPEAKER, handset, or headset microphone to prevent the other person from hearing you. The
associated LED lights steadily when the handset or headset is muted.

The Telephone:
1.1 Call Appearance Keys
There are four pages of call appearance and function keys. You can search through these by pressing and . At
default, first page of the main call screen contains three keys set as ‘call appearance’ keys. With these keys the phone is
a multi-line phone, indicated as a=, b= and c=. The remaining 21 Function Keys can have system features allocated to
them, by your system administrator, that are specific to your requirements (see Function Keys ).
Your system administrator can allocate a call appearance key with:
· A Bridged Appearance
A bridged appearance key matches the status and operation of the call appearance key on a pre-defined colleague’s
phone. Hence, you can pick-up, make and receive calls on behalf of your colleague.
· A Line Appearance
An IP Office exchange line (but not IP lines) can be allocated to you such that the status of that line is displayed and
you can use the line appearance key to make and receive calls.
· Call Coverage Appearance
A call coverage appearance key alerts you when a pre-defined colleague is receiving a call. The covered user does
not need to be using call appearance keys. Hence, you can pick-up calls on behalf of your colleague.
· System Features
System Features, such as Abbreviated Dial (that automatically dials a frequently used number) can be set against
key and/or dial pad digits. See Function Keys .
Having more than two call appearance keys is very useful. When holding a call, you can answer or make another call and
then switch between calls, transfer or conference. If you are set to receive call waiting indication, the waiting call is
shown against the next call appearance key.
Note
· If your phone is operating in single line mode, call appearance keys are not available.
44
44
Caution
· Although the system administrator can replace the call appearance keys with Bridged, Line and Call Coverage
Appearance keys, this would severely restrict the use of features such as conference and transfer.
It is for this reason that it is strongly recommended that all call appearance keys remain at their default
settings.

2.13 Private Call
The Private Call feature is used to prevent any intrusions during the call. Private call can be activated either before or
during a call and will set the phone status to 'cannot be intruded' until you switch the Private Call feature off.
If you place a call to an extension with Private Call on, you will hear the Number Unobtainable tone.
Note
· Private call is not a default feature. If you require this option, contact your administrator.
