Introducing the Prestige
This chapter introduces the main features and applications of the Prestige.
1.1 Prestige VoIP Analog Telephone Adaptor Overview
The Prestige is a SIP-based VoIP analog telephone adaptor (ATA). Sending voice signals over
the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an
internationally recognized standard for implementing VoIP.
The Prestige allows you to use a traditional analog telephone to make and receive Voice over
IP calls. You can call any landline or mobile telephone as well as IP telephones. You don’t
need to know if the recipient’s connection type is an IP, cellular or landline based service.
Calls received from IP telephones work exactly as you would expect from the traditional
telephone service.
The Prestige’s two Ethernet ports allow you to connect the Prestige to your LAN and connect
your computer to the Prestige. This way your computer can still access the LAN without
adding an extra Ethernet switch.
The Prestige's web configurator allows easy management and configuration.
1.2 Prestige 2002L VoIP Analog Telephone Adaptor with
Lifeline
The Prestige 2002L has all of the features of the Prestige 2002 and adds the PSTN (Public
Switched Telephone Network) lifeline feature. PSTN lifeline lets you have VoIP phone
service and PSTN phone service at the same time.
