Overview

The Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide (H.323)
provides the information you need to install, configure and manage the CiscoATA 186 and
Cisco ATA188 on an H.323 network.

Audience

This guide is intended for service providers and network administrators who administer Voice over IP
(VoIP) services using the CiscoATA. Most of the tasks described in this guide are not intended for end
users of the CiscoATA. Many of these tasks impact the ability of the CiscoATA to function on the
network, and require an understanding of IP networking and telephony concepts.
