Feature Overview

Cisco SPA100 Series Analog Telephone Adapters (ATA) provide access to Internet

phone services through two standard telephone RJ-11 phone ports using

standard analog telephone equipment. 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.

Each 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.
