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.

•Choosing Authentication and Encryption Methods

Configuring Network Access for the Cisco Unified Wireless IP Phone

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 Profiles on the Cisco Unified Wireless IP Phone 7920."

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.

Overview of Configuring and Installing the Cisco Unified Wireless IP Phone 7920

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

•Installing Cisco Unified IP Phones

Configuring Cisco Unified IP Phones in Cisco Unified CallManager

To add phones to the Cisco Unified CallManager database, you can use:

•Auto-registration

•Cisco Unified CallManager Administration

•Bulk Administration Tool (BAT)

•BAT and the Tool for Auto-Registered Phones Support (TAPS)

For more information about these choices, see the "Methods for Adding Phones to Cisco Unified CallManager" section.

For general information about configuring phones in Cisco Unified CallManager, refer to the "Cisco Unified IP Phone" chapter in the Cisco Unified CallManager System Guide.

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.
