Zoom Gateway/Router Zoom V3 - Manual (Page 5)

Overview 5
Overview
The V3 is a gateway/router with a TelePort ™ VoIP phone port.
You use the V3 in conjunction with an Ethernet cable modem or
Ethernet ADSL modem to connect to the Internet. The
gateway/router provides an interface between the Internet and
your local area network (LAN). It also includes an advanced
firewall, which allows you to control Internet access from your
local network and which protects your local network from
unwanted Internet traffic. The TelePort lets you use an ordinary
telephone to make VoIP calls over the Internet and regular calls
through the familiar Public Switched Telephone Network (PSTN).
This User Guide contains installation instructions and explains how
to configure the V3 for some popular applications. Most users
should go now to the next chapter, Installation Instructions.
Note:
If you are an Internet service provider, a VoIP service provider, or a system
administrator, additional information is available in the Technical Reference
