Cisco Small Business ATA Administration Guide 16
Introducing Cisco Small Business Analog
Telephone Adapters
This guide describes the administration and use of Cisco Small Business analog
telephone adapters (ATAs). These ATA devices are a key element in the end-to-
end IP Telephony solution. An ATA device provides user access to Internet phone
services through one or more standard telephone RJ-11 phone ports using
standard analog telephone equipment. The ATA device connects to a wide area IP
network, such as the Internet, through a broadband (DSL or cable) modem or
router. The ATA can be used with an onsite call-control system such as the
SPA9000 Voice System or legacy PBX, or with an Internet-based call-control
system.

Figure 2 ATA Deployment with Onsite Call Control
This chapter introduces the functionality of the ATA devices and describes the
features that are available.
Refer to the following topics:
•“Comparison of ATA Devices,” on page 17
•“ATA Connectivity Requirements,” on page 20
•“ATA Software Features,” on page 26
Comparison of ATA Devices
Each ATA device is an intelligent low-density Voice over IP (VoIP) gateway that
enables carrier-class residential and business IP Telephony services delivered
over broadband or high-speed Internet connections. An ATA device maintains the
state of each call it terminates and makes the proper reaction to user input events
(such as on/off hook or hook flash). The ATA devices use the Session Initiation
Protocol (SIP) open standard so there is little or no involvement by a “middle-man”
server or media gateway controller. SIP allows interoperation with all ITSPs that
support SIP.
The ATA Models table summarizes the ports and features provided by the ATA
devices described in this document.

ATA Models
NOTE 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.
The following figure illustrates how the different ATA devices provide voice
connectivity in a VoIP network.

•The PAP2T and the SPA8000 provide FXS ports to connect fax machines and
analog phones to IP telephone services.
•The SPA3102 and the SPA8800 act as SIP-PSTN gateways.
•The WRTP54G router provides ports for analog telephone devices and
provides QoS in the form of priority packet queueing.

ATA Connectivity Requirements
Cisco Small Business ATA Administration Guide 20
1
ATA Connectivity Requirements
An ATA device can be connected to a local router, or directly to the Internet. Each
phone connected to an RJ-11 (analog) port on the ATA device connects to other
devices through SIP, which is transmitted over the IP network.
In order to ensure connectivity between the devices connected to its FXS ports,
the ATA device requires the following functionality to be supplied on the network
connected to its Ethernet port:
•Connection to an IP router with hairpinning support
•Connection to an outbound Proxy server
When a phone connected to the ATA device communicates with another phone, it
sends a SIP packet onto the internal LAN. The packet is then forwarded to the
external LAN or directly to the Internet. The source address and source port on the
original packet are assigned by the ATA device DHCP server. The address and
port are translated by the ATA device using Network Address Translation (NAT)
and Port Address Translation (PAT). The packet is then routed back to the internal
network on the ATA device by the local router or the ISP router.
Problems can occur with calls between phones connected to the ATA device
when an outbound proxy or a router with hairpinning support is not available. The
ATA device cannot directly connect the two telephone devices, but requires a
local or remote router to route the packet back to its destination on the local
network from which it originated.
The necessary routing can be provided by a router with hairpinning support, or by
an outbound SIP proxy, which is typically provided by the Internet Telephony
Service Provider (ITSP). When relying on the ITSP for interconnecting phones on
the ATA device, local phones connected to the ATA device are unable to
communicate with each other if the Internet connection is not available for any
reason. It is recommended you connect the ATA device to a local router that
provides hairpinning support to prevent this problem.
