The Cisco Unified IP Phone 7931G meets the communication needs of retail, commercial, manufacturing workers, and anyone with moderate telephone traffic but also specific call requirements. Dedicated hold, redial, and transfer keys facilitate call handling in a retail environment. Illuminated mute and speakerphone keys give a clear indication of speaker status.

A pixel-based display with a white backlight makes calling information easy to see, and Extensible Markup Language (XML) services deliver a rich user experience. The Cisco Unified IP Phone 7931G offers numerous important security features plus the choice of IEEE 802.3af Power over Ethernet (PoE) or local power through an optional power adaptor.


The Cisco Unified IP Phone 7931G is designed to grow with your organization. A dynamic, soft-key activated feature set allows the phone to keep pace with your requirements through regular software upgrades. You can easily move phones, add new phones, and change existing phone arrangements; users can simply pick up their phones and move to a new location anywhere on the network. The Cisco Unified IP Phone 7931G also provides accessibility features for those with special needs.

Tables 1 through 6 present the features, specifications, and compliance information for the Cisco Unified IP Phone 7931G, Table 7 and 8 provides ordering information, and Table 9 lists available optional accessories.

Features, Specifications & Compliance Information

Table 1. Device Features and Descriptions

Lighted Line KeysTwenty-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 keysDedicated 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 indicatorLights 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 displayA 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 keyThese keys dynamically present calling options to the user. The four-way rocker key allows easy movement through the displayed information.
Network featuresNetwork features include Cisco Discovery Protocol and IEEE 802.1 p/q tagging and switching.
Ethernet switchThe phone offers 10/100BASE-T Ethernet connection through two RJ-45 ports: one for the LAN connection and the other for connecting a downstream Ethernet device such as a PC.
SpeakerphoneA full-duplex speakerphone enables the user to handle calls hands-free.
Volume controlA volume-control toggle provides easy decibel-level adjustments of the handset, headset, speakerphone, and ringing volume.
Headset portA dedicated headset port eliminates the need for a separate amplifier when using a headset; it allows the handset to remain in its cradle, making headset use simpler.
Single-position foot standThe phone offers optimum display viewing and comfortable use of buttons and keys. The foot stand can be removed for wall mounting with mounting holes located on the base of the phone.
Multiple ring tonesThe phone offers more than 24 user-selectable ring tones.
American Disabilities Act (ADA) featuresA hearing-aid-compatible (HAC) handset meets ADA requirements, including ADA HAC requirements for a magnetic coupling to approved hearing aids; the phone dialing pad also complies with ADA requirements.
Signaling protocol supportThe phone is compatible with Cisco Unified Communications Manager Express Version 4.0(2) and later, using the Skinny Client Control Protocol (SCCP) or Cisco Unified Communications Manager 6.0 and later.
Codec supportThe phone supports G.711a, G.711u, G.729a, G.729b, and G.729ab audio-compression codecs.
Configuration optionsNetwork parameters can be provisioned through the Dynamic Host Configuration Protocol (DHCP).
Voice qualityComfort-noise generation and voice-activity-detection (VAD) programming is offered on a system basis.
