Cisco IP Phone Models 7960 and 7940

1   Overview

This guide is designed to help you quickly set up and use your Cisco IP Phone 7960 or Cisco IP Phone 7940. For information on accessing more complete phone documentation over the Web, see the "Related Documentation" section.

2   Connecting Your Cisco IP Phone

Chances are, your system administrator or a technician will connect your new Cisco IP Phone to the corporate IP telephony network. If that is not the case, connecting your phone is easy.


Follow the steps below. Refer to Figure 1 to locate ports on the back of your phone.

Before You Begin

Verify that your system administrator is ready for you to connect your Cisco IP Phone to the network.

Be sure to read the "Safety Notices" section before connecting or using your phone.

Step 1   Connect your Cisco IP Phone to the corporate IP telephony network. You can do this in one of two ways, depending on how your workspace is set up. See your system administrator if you are not sure which method to choose:

Step 2   Connect the handset to the handset port. Ensure that the end of the cord with the longer uncoiled section is connected to the body of the phone.

Step 3   If you use a headset, connect it to the headset port. For supported headsets, see http://cisco.getheadsets.com/and http://vxicorp.com/cisco

Step 4   If your system administrator delivered your Cisco IP phone with a power supply, connect the power supply plug to the DC48V AC adapter port on the back of the phone.

If your system administrator delivered your phone without a power supply, your phone probably receives power through the Ethernet connection.

Step 5   Use the power cable to connect the power supply to a standard power outlet in your workspace.

Step 6   Adjust the footstand height by gently pulling the footstand away from the body of the phone. To release the footstand, press the footstand adjustment knob.

Once you connect the Cisco IP Phone to its power source, a start-up process begins. After several minutes, the phone's LCD displays a neutral "ready" screen. The details on your screen might vary, but a ready screen typically displays the date and time, your extension number, and available soft keys. Startup is complete and your phone is ready to use.


Soft keys point to feature options displayed along the bottom of your LCD screen. Soft keys are flexible—they change depending on the status of your phone. For example, you can see one set of soft key options when you pick up the handset, and another set when the phone is not in use.

3   Introducing Your Cisco IP Phone

The Cisco IP Phone 7960 and Cisco IP Phone 7940 are full-feature telephones that provide voice communication over an IP (Internet Protocol) network. These phones function much like traditional analog phones, allowing you to place and receive telephone calls. They also support features that you have come to expect from a telephone—such as speed dialing, redial, call transfer, conference calling, and voice mail access.

Your Cisco IP Phone also offers features that might surprise you. Because it is part of an IP network, your Cisco IP Phone can capture not only voice, but data content—including up-to-the-minute information from the Internet through an XML application. In a nutshell, your Cisco IP Phone provides a whole range of communication features that you could not expect from a traditional telephone.

Why Does One Cisco IP Phone Behave Differently than Another?

The features exhibited by your Cisco IP Phone depend upon the call processing environment (or "protocol") that your phone uses. You can see what protocol your Cisco IP Phone uses by looking at the LCD screen when the phone is idle. Refer to Table 1 to identify your protocol.

Table 1: Identifying the Protocol Used by Your IP Phone
If you see Your phone uses

A "SIP" icon in the upper right corner of the phone's LCD screen.

Session Initiation Protocol (SIP)

A MGCP icon (the letter "m" topped by a curved line) in the upper right corner of the phone's LCD screen.

Media Gateway Control Protocol (MGCP)

The absence of an icon in the upper right corner of the phone's LCD screen.

Note this exception: If you activate the "Call Forward All" feature on a Cisco CallManager phone, an animated phone icon appears on the black line in the upper right corner of the LCD. Press the CFwdAll soft key to deactivate this feature.

7   Safety and Compliance

Please read the following sections before installing or using your Cisco IP Phone.

Safety Notices

These safety notices apply to the Cisco IP Phone models 7960 and 7940. For translated versions, see the Cisco IP Phone 7900 Family Administration Guide. This document is accessible via the Web at the following URL:


This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents.

Read the installation instructions before you connect the system to its power source.

Ultimate disposal of this product should be handled according to all national laws and regulations.

Do not work on the system or connect or disconnect cables during periods of lightning activity.

To avoid electric shock, do not connect safety extra low voltage (SELV) circuits to telephone network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports use RJ-45 connectors. Use caution when connecting cables.

The following warnings apply when you use the external power supply with the Cisco IP Phone:

This product relies on the building's installation for short-circuit (over current) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors).

The device is designed to work with TN power systems.

The Cisco IP Phone 7960 and Cisco IP Phone 7940 are inoperable during a power outage if not supported by a UPS (uninterruptible power supply). This caution applies when you are using either a local transformer or inline power on the LAN, and might affect your ability to reach 911.
