Additional ATA models, Cisco SPA112, SPA122, and SPA232D are covered in
separate Quick Start Guides and administration guides. For links to all ATA
documentation, see www.cisco.com/go/smallbizvoicegateways.
The information contained in this guide is not a warranty from Cisco. Customers
planning to use ATA devices in a VoIP service deployment are advised to test all
functionality they plan to support before putting the ATA device in service. By
implementing ATA devices with the SIP protocol, intelligent endpoints at the edges
of a network perform the bulk of the call processing. This allows the deployment of
a large network with thousands of subscribers without complicated, expensive
servers.
