Introduction

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.

Features

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

FeatureDescription
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.
