Features of Your Cisco Unified IP Phone

Phone Overview

The Cisco Unified IP Phone 7931G is a full-feature telephone that provide voice communication over the same data network that your personal computer uses, which allows you to place and receive phone calls, put calls on hold, transfer calls, and make conference calls.

It is designed to meet the communication needs with moderate telephone traffic and specific call requirements. It provides you with dedicated hold, redial, and transfer keys to facilitate call handling and enhanced productivity features that extend your call-handling capabilities:

  • Access to network data, XML applications, and web-based services.

  • Online customization of phone features and services from your Cisco Unified Communications Manager User Options web pages.

  • A comprehensive online help system that displays information on the phone screen.

Line and Call Definitions

The terms lines and calls can be easily confused.


There are 24 programmable buttons. Typically, your system administrator assigns some of these lines (up to 24) to be used as lines for making and receiving calls. Each corresponds to a directory number or intercom number that others can use to call you.

Some of your lines may share the same directory number, and others may have unique directory numbers. To see your phone lines, use the Navigation button to scroll through the list of programmable button display.

Buttons configured as lines display their assigned directory number and associated button number. For example, if you have directory number "3105" assigned to button 1, the line appears as 3105:01 on the phone screen. Each line also has an associated icon to help you identify the purpose.


Each line can support a single call. If multiple lines share a directory number, each line can still support one call each.

Line and Call Icons

Your phone displays icons to help you determine the line and call state and feature accessibility on each line.

SIP and SCCP Signaling Protocols

Your system administrator configures your phone with one of two signaling protocols: Session Initiation Protocol (SIP) or Skinny Call Control Protocol (SCCP).

Phone features can vary depending on the protocol. This guide indicates which features are protocol-specific. To learn which protocol your phone is using, contact your system administrator.

Energy Savings

Your phone supports the Cisco EnergyWise program. Your system administrator sets up sleep (power down) and wake (power up) times for your phone to save energy.

Ten minutes before the scheduled sleep time, if audible alert is enabled by your system administrator, you hear your ringtone play. The ringtone plays according to the following schedule:

  • At 10 minutes before power down, the ringtone plays four times

  • At 7 minutes before power down, the ringtone plays four times

  • At 4 minutes before power down, the ringtone plays four times

  • At 30 seconds before power down, the ringtone plays 15 times or until the phone powers off

If your phone is inactive (idle) at the sleep time, you see a message to remind you that your phone is going to power down. To keep the phone active, press any key on the phone. If you do not press any key, your phone powers down.

If your phone is active (for example, on a call), your phone waits until it has been inactive for a period of time before informing you of the pending power shutdown. Before the shutdown happens, you see a message to remind you that your phone is going to power down.

At the scheduled time, your phone powers up. To wake up the phone before the schedule time, contact your administrator.

Wake and sleep times are also linked to the configured days that you normally work. If your requirements change (for example, your work hours or work days change), see your system administrator to have your phone reconfigured.

For more information about EnergyWise and your phone, contact your system administrator.
