Introduction
This document explains 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
