Chapter 1 Getting To Know Your Prestige

Figure 1   Prestige Internet Access Application

For a SOHO (Small Office/Home Office) environment, your Prestige offers the Single User 
Account (SUA) feature that allows multiple users on the LAN (Local Area Network) to access 
the Internet concurrently for the cost of a single IP address

In a home or small office environment, you can use the Prestige to make and receive VoIP 
telephone calls through an Internet Telephony Service Provider (ITSP). 
The following figure shows a basic example of how you would make a VoIP call through an 
ITSP. You use your analog phone (A in the figure) and the Prestige (B) changes the call into 
VoIP. The Prestige then sends your call to the Internet and the ITSP’s SIP server. The VoIP 
call server forwards calls to PSTN phones (E) through a trunking gateway (D) to the PSTN 
network. The VoIP call server forwards calls to IP phones (F) through the Internet.

Figure 2   Internet Telephony Service Provider Application

Use the Prestige to make a call to the recipient’s IP address without using a SIP proxy server 
Peer-to-peer calls are also called “Point to Point” or “IP-to-IP” calls. You must know the 
peer’s IP address in order to do this.
