This section describes the controls on your IP Deskphone. Your IP
Deskphone can have fixed keys with icons or with labels. This document
presents both versions of the fixed key.
The keys on either side of the LCD display
area are User-defined feature keys, with
labels on the LCD. The system administrator
can reserve some keys for specific functions
during tasks and for advanced configuration.
You can define these keys for specific
functions, such as Call Forward.
Note: The key on the lower right is
reserved as your default line key.
Context-sensitive soft keys are located
below the display area. The LCD label above
each key changes based on the active
feature.
Use the Volume control buttons to adjust
the volume of the ringer, handset, headset,
speaker, and the Handsfree feature. Press
the top button to increase the volume, and
press the bottom button to decrease the
volume.
Press the Mute key to listen to the call
without transmitting. Press the Mute key
again to return to two-way conversation. The
Mute key applies to handsfree, handset, and
headset microphones.
Note: When you enable mute, a red
LED on the Mute key remains lit.
