An Overview of the Cisco Unified
Wireless IP Phone 7920
The Cisco Unified Wireless IP Phone 7920 provides wireless voice
communication over an Internet Protocol (IP) network. Like traditional analog
telephones, you can place and receive phone calls and access features such as
hold, transfer, and speed dial. In addition, because the phone connects to your
wireless LAN, you can place and receive phone calls from anywhere in your
wireless environment.
This chapter includes the following topics:
• Understanding the Cisco Unified Wireless IP Phone 7920, page 1-1
• Features Supported on the Cisco Unified Wireless IP Phone 7920, page 1-3
Understanding the Cisco Unified Wireless IP Phone 7920
The Cisco Unified Wireless IP Phone 7920 is an 802.11b wireless device that
provides comprehensive voice communications in conjunction with
Cisco Unified CallManager and Cisco Aironet 802.11b Access Points (APs) in a
private business communications network.This phone model supports G.711a,
G.711u, and G.729a audio compression coder-decoders (codecs). You must
configure and manage a Cisco Unified Wireless IP Phone like other IP phones and
wireless devices on your network.The wireless IP phone supports multiple lines
and most of the IP phone features of other Cisco Unified IP Phone models.

templates, among other tasks. For more information, see Chapter 7, “Configuring
Features, Templates, Services, and Users.”
In some places, this manual provides partial instructions for procedures that
involve Cisco Unified CallManager Administration. These instructions are
intended to point you to the appropriate page in the Cisco Unified CallManager
application and to provide some initial guidance.
For more information about the Cisco Unified CallManager Administration
application, refer to Cisco Unified CallManager documentation, including Cisco
Unified CallManager Administration Guide. You can also use the
context-sensitive help that is available within the application. Access
context-sensitive help by choosing

Features Supported on the Cisco Unified Wireless IP Phone 7920
Configuring Security for the Cisco Unified Wireless IP Phone
Implementing security in the voice over WLAN protects against data tampering
threats and identity theft of phones. To alleviate these threats, the Cisco wireless
LAN provides many options for user authentication with servers and for
encrypting communications streams between phones and network devices.
For information about supported security options for the Cisco Unified Wireless
IP Phone 7920, see the “Security Mechanisms in the Wireless Network” section
on page 2-14.

Configuring Network Access for the Cisco Unified Wireless IP Phone
1-6
Like other network devices, you must configure IP phones to access Cisco Unified
CallManager and the rest of the IP network using the wireless LAN. There are two
methods for configuring network settings such as DHCP, TFTP, and for wireless
settings for the phone.
• Cisco 7920 Configuration Utility
• Network Config menu on the Cisco Unified Wireless IP Phone 7920
You install the Cisco 7920 Configuration Utility on a computer and connect to the
Cisco Unified Wireless IP Phone 7920 with a USB cable to configure phone and
network settings. For more information, see Chapter 4, “Using the Cisco 7920
Configuration Utility.”
You can also configure network settings on the phone itself. For more information
about configuring features from the phone, see Chapter 5, “Configuring Network
Profile Settings.”
Because the Cisco Unified Wireless IP Phone is a network device, you can obtain
detailed status information about it. This information can assist you in
troubleshooting problems that users might encounter when using their IP phones.
See Chapter 8, “Viewing Status, Statistics, and Firmware Information on the
Cisco Unified Wireless IP Phone 7920,” for tips on using this information.

Providing Users with Feature Information
If you are a system administrator, you are the primary source of information for
Cisco Unified Wireless IP Phone users in your network or company. To ensure
that you distribute the most current feature and procedural information,
familiarize yourself with Cisco Unified Wireless IP Phone 7920 documentation.
Make sure to visit the Cisco Unified IP Phone web site:
http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/index.htm
From this site, you can view and order additional phone documentation. For
complete ordering information, see the “Obtaining Documentation” section on
page xviii.
In addition to providing documentation, it is important to inform users about
available Cisco Unified IP Phone features—including features specific to your
company or network—and about how to access and customize those features, if
appropriate.
For a summary of the key information that you can provide to phone users, see
Appendix A, “Providing Information to Users By Using a Website.”
Note The radio frequency (RF) for the Cisco Unified Wireless IP Phone 7920 is
configured for a specific regulatory domain. If users attempt to use this phone
outside of the regulatory domain, the phone will not function properly and they
might violate local regulation.

When deploying a new IP telephony system, system administrators and network
administrators must complete several initial configuration tasks to prepare the
network for IP telephony service. For information and a checklist for setting up
and configuring a complete Cisco IP telephony network, refer to the “System
Configuration Overview” chapter in the Cisco Unified CallManager System
Guide.
To add Cisco Unified Wireless IP Phones to the IP network, system administers
also need to perform a site survey to determine where to place and install access
points (APs) for wireless voice coverage. For detailed information about a voice
over WLAN deployment, refer to the Cisco Unified Wireless IP Phone 7920
Design and Deployment Guide.
After you have set up the IP telephony system and configured system-wide
features in Cisco Unified CallManager, you can add IP phones to the system.
The following topics provide an overview of procedures for adding Cisco Unified
IP Phones to your network:
• Configuring Cisco Unified IP Phones in Cisco Unified CallManager,
page 1-8
• Installing Cisco Unified IP Phones, page 1-13
Configuring Cisco Unified IP Phones in Cisco Unified CallManager
To add phones to the Cisco Unified CallManager database, you can use:
• Auto-registration

Installing Cisco Unified IP Phones
After you have added the phones to the Cisco Unified CallManager database, you
can complete the phone installation. You (or the phone users) can install the phone
at the users’s location. The Cisco Unified IP Phone Installation Guide that ships
in the box with each phone provides directions for assembling the phone and
accessories and charging the battery.
Prior to using the phone to connect to the wireless LAN, you need to configure a
network profile for the phone. You can use the Cisco 7920 Configuration Utility
to set up the network profile and other phone settings, or you can configure the
network profile using phone menus.
If you use auto-registration with Cisco Unified CallManager, you need to update
the specific configuration information for the phone such as associating the phone
with a user, changing the softkey template, or directory number.
Note Before you install a phone, even if it is new, upgrade the phone to the current
firmware image. For information about upgrading, refer to the Readme file for
your phone which is located at:
