Table 1. Features and Descriptions
Feature Description
Lighted line keys Twenty-four lighted line keys to which individual lines can be assigned—Each line key
provides a busy-line indication if the line is shared with another IP phone. Lighted line keys
are also used to access services and call history directories and to activate the headset
port.
Dedicated hold, redial, and
transfer keys
Dedicated keys for hold, redial, and transfer—The hold key is colored red to make it clearly
visible in a fast-moving call environment; the redial and transfer keys facilitate rapid call
handling.
Lighted message waiting
indicator
Lights turn on when there is new voicemail and when the phone rings; the message waiting
indicator is visible on both the phone chassis and handset, and it stays lit until the user
processes new voicemail.
Graphical display A graphical monochrome display with resolution of 192 x 64 pixels and a white backlight
provides scrollable three-line intuitive access to calling features and text-based XML
applications. The Cisco Unified IP Phone 7931G also supports audio-based XML
applications.
Four soft keys and a four-way
rocker key
These keys dynamically present calling options to the user. The four-way rocker key allows
easy movement through the displayed information.

LAN connection and the other for connecting a downstream Ethernet device such as a PC.
Speakerphone A full-duplex speakerphone enables the user to handle calls hands-free.
Volume control A volume-control toggle provides easy decibel-level adjustments of the handset, headset,

foot stand can be removed for wall mounting with mounting holes located on the base of the
phone.
Multiple ring tones The phone offers more than 24 user-selectable ring tones.
