The Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide (SIP) provides
the information you need to install, configure and manage the Cisco ATA 186 and Cisco ATA 188 on a
Session Initiation Protocol (SIP) network.

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