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.
