Cisco 7920 Unified Wireless IP Phone SpareThe Cisco Unified Wireless IP Phone 7920 is an easy-to-use IEEE 802.11b wireless IP phone that provides comprehensive voice communications in conjunction with Cisco Unified Communications Manager and Cisco Unified Communications Manager Express. Features. Backlit display (128x80 pixels). 802.11b WiFi. 500-1000 ft.
This document describes how to configure the Cisco 7920 Wireless IP Phone (Cisco 7920) in common network scenarios. It starts with the most basic configuration required to implement a Cisco 7920.

It goes on to explain the next level of complexity, which is the use of VLANs. The final level of complexity is the use of Cisco Secure Access Control Server (ACS) for security. The goal of this document is to provide the reader with a single document that covers the basic tasks required to implement a Cisco 7920 in a lab environment, so that the user can use these skills to implement a Cisco 7920 in a live environment. The reason that this document is targeted at a lab environment is that it is impossible to cover, in a single document, all of the possible permutations of equipment and features that are available to implement a Cisco 7920 in a live environment.The Cisco 7920 is the first Cisco product to combine Voice over IP (VoIP) technology, Wireless LAN (WLAN) technology, Quality of Service (QoS), and Access/Authentication/Authorization (AAA) security. In order to successfully implement and support the Cisco 7920, system administrators must become familiar with all of these technology areas.This document was created primarily for readers who have limited experience with one or more of the products and technologies required to install and configure a Cisco 7920 IP Phone. It will also benefit readers that have a great deal of experience in some of the areas but not others.QoS is not covered in this document, because it is not required that you implement QoS to bring a Cisco 7920 online to place calls. The page contains links to several very good documents about the implementation of QoS in VoIP environments.This document also provides some troubleshooting guidelines.
It is not intended to be a complete manual to install, configure, or troubleshoot the Cisco 7920 or any of the other components that are used in this document. The related documents that contain more detailed instructions are referenced in the subsequent sections, as appropriate.WLAN infrastructure devices—such as the Cisco Aironet 350 Series Access Point (AP) or the Cisco Aironet 1200 Series AP—treat the Cisco 7920 the same as any other wireless 802.11b client. Cisco CallManager treats the Cisco 7920 like any other Cisco 7960 IP Phone. You can use the knowledge and skills that you already have in these areas when you install, configure, and troubleshoot a Cisco 7920.This document assumes that you have an operational Cisco CallManager 3.2 or later, a Catalyst switch that supports 802.1Q VLANs, and a Cisco Secure ACS (if you are going to do Light Extensible Authentication Protocol LEAP).
