Configuring the Cisco Phone Proxy

This chapter describes how to configure the ASA for Cisco Phone Proxy feature.

This chapter includes the following sections:

•Information About the Cisco Phone Proxy, page 17-1

•Licensing Requirements for the Phone Proxy, page 17-4

•Prerequisites for the Phone Proxy, page 17-6

•Phone Proxy Guidelines and Limitations, page 17-12

•Configuring the Phone Proxy, page 17-14

•Feature History for the Phone Proxy, page 17-22

Information About the Cisco Phone Proxy

The Cisco Phone Proxy on the ASA bridges IP telephony between the corporate IP telephony network and the Internet in a secure manner by forcing data from remote phones on an untrusted network to be encrypted.

Phone Proxy Functionality

Telecommuters can connect their IP phones to the corporate IP telephony network over the Internet securely via the phone proxy without the need to connect over a VPN tunnel as illustrated by Figure 17-1.
