Introducing the ZyXEL Device
This chapter introduces the main features and applications of the ZyXEL Device.
1.1 P-2302R-P1 VoIP ATA / Station Gateway Series Overview
The Prestige P-2302R-P1 VoIP (Voice over IP) station gateway lets you use traditional analog
telephones to make telephone calls over the Internet. The ZyXEL Device uses SIP (Session
Initiation Protocol), an internationally recognized standard for implementing VoIP.
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 NAT and DHCP server features allow you to use an Ethernet hub or switch to set up a
private network and allow multiple computers to share a single Internet connection. The
ZyXEL Device also provides content filtering and a firewall for security.
The ZyXEL Device's web configurator allows easy management and configuration.
1.2 P-2302RL-P1 VoIP ATA / Station Gateway with PSTN Line
The P-2302RL-P1 has all of the features of the P-2302R-P1 and adds the PSTN (Public
Switched Telephone Network) line. A PSTN line lets you have VoIP phone service and PSTN
phone service at the same time.
Note: If the P-2302RL-P1 is turned off, you can only use the phone that is connected
to the
PHONE1 port to make phone calls, regardless of the settings in any
screen. Make sure you know which phone this is, especially in case you want to
make an emergency call.
