Feature Overview

Cisco SPA232D Administration Guide
Thank you for choosing the Cisco SPA232D Mobility Enhanced Analog Telephone
Adapter (ATA). This chapter provides more information about the features of the
product and provides instructions about connecting the equipment and getting
started in the web-based configuration utility.
With the Cisco SPA232D Mobility Enhanced ATA, you can provide your analog
phone and Cisco SPA302D cordless handsets with access to analog and Internet
phone services through a standard RJ-11 phone port and a built-in DECT base
station. The ATA supports up to five Cisco SPA302D handsets. The ATA connects
to the Internet through a broadband (DSL or cable) modem or router. The ATA can
be used with an on-site call-control system or an Internet-based call-control
system.
The ATA 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 maintains the state of each
call it terminates and reacts appropriately to user input events (such as on/off hook
or hook flash). The ATAs 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 inter-operation with all ITSPs that support SIP.
The system supports four simultaneous calls, including "active" calls and "on-hold"
calls. A phone or DECT handset can handle one on-hold call and one active call
simultaneously.
