Your Analog Telephone Adapter
The ATA 191 and ATA 192 analog telephone adapters are telephony-device-to-Ethernet adapters that allow
regular analog phones to operate on IP-based telephony networks. Both models support two voice ports, each
with an independent phone number. Both have an RJ-45 10/100BASE-T data port while the ATA 192 has an
additional Ethernet port.
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 on/off hook or
hook flash. The ATAs use the Session Initiation Protocol (SIP) open standard so there is little or no involvement
