Feature Overview
Cisco SPA100 Series Analog Telephone Adapters (ATAs) provide your standard
analog phones with access to Internet phone services through two standard
telephone RJ-11 phone ports. 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 can handle one on-hold call and one active call simultaneously.
