1.2.3 Make Peer-to-peer Calls

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.
The following figure shows a basic example of how you would make a peer-to-peer VoIP call.
You use your analog phone (A in the figure) and the Prestige (B) changes the call into VoIP.
The Prestige then sends your call through the Internet to the peer VoIP device (C).

1.2.4 Firewall for Secure Broadband Internet Access

The Prestige provides protection from attacks by Internet hackers. By default, the firewall
blocks all incoming traffic from the WAN. The firewall supports TCP/UDP inspection and
DoS (Denial of Services) detection and prevention, as well as real time alerts, reports and logs.
