Overview
The
Ethernet/Modem Telephone AT-22DS is a next generation SIP IP
Phone with ethernet and built-in modem interfaces that provides
a cost-saving solution for small business/home users on their
telecommunication needs. The AT-22DS is following the open standard
RFC-3261 SIP protocol to make sure that the user can easily
install his IP phone on most of the existing VoIP (Voice over
IP) services. By using the state-of-the-art DSP (Digital Signal
Processing) technology, the AT-22DS delivers outstanding voice
quality that is very comparable to the PSTN voice quality. With
the built in LCD display, the user can easily configure the
AT-22DS for first time installation in a few minutes. And besides
the advanced VoIP functions in easy installation, AT-22DS also
provides rich telephone features such as the last number redial,
