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
Manual at www.zoom.com
The Technical Reference manual includes information such as voice parameters
and dialing plan configurations.

Overview

USB Cable

Zoom V3 User’s Guide

The CD contains the Installation Software, User Manual, Warranty,
and Customer Support information.
In addition, you may have a phone-jack adapter to adapt the RJ-11
phone cord for a different phone jack (certain countries only).
If anything is missing or damaged, contact Zoom Customer
Support or your retailer or distributor.

What You Will Need
•
•
•
•
•

An Ethernet cable modem or Ethernet DSL modem.
A Windows, Macintosh, or Linux computer equipped with
a Network Interface Card (NIC) or a USB port.
A telephone to plug into the V3 if you plan to use VoIP.
An accessible telephone jack (a jack where you can plug in a
regular telephone and make calls).
A DSL phone filter.

Chapter 1: Installation Instructions

1.2 Quick Start Instructions
Installing the V3 involves five steps: Installing the Software,
Installing the Hardware, Configuring Internet Explorer,
Configuring Your V3, and Setting Up VoIP Service.

Step 1: Installing the Software
Installing the software is only required for people connecting a
Windows computer directly to the V3. All others should skip to
Step 2: Installing the Hardware.
If your computer has an available Ethernet jack, we recommend
that you use it instead of the USB jack. This will simplify
installation.
If you decide to use the V3’s USB jack, you must remove any
previously installed USB modem drivers on your computer
before installing this software. On the desktop, click the Start
button, point to Settings, and select Control Panel. In Control
Panel, double-click Add/Remove Programs, on the
Install/Uninstall tab, select your old USB modem from the list,
and click Remove. Now continue below.

1 Your computer must be on. Insert the supplied CD into

your computer’s CD drive. The CD should start automatically
and the Select Language screen should appear. (If the CD
does not start automatically, on the desktop, click the Start
button, click Run, and then type D:\setup.exe, where D is
the letter of your CD drive.)

2 Select your language and click the Installation Wizard
button. The software installation proceeds automatically.

3 When the process is complete, you will be prompted to click
Finish and then Shut Down to turn off your computer.
Remove the CD from your CD drive before you shut down
your computer.

Zoom V3 User’s Guide

Step 2: Installing the Hardware
Installing the Hardware is a two-step process, Making the
Connections, and Powering Up.

Making the Connections

1 The software must be installed before you proceed.
Then, unplug or turn off the power to your PC and
everything connected to your PC.

2 Plug your phone into the V3’s PHONE jack.

If you have a cordless phone with one or more handsets, plug
the base station into the V3’s PHONE jack.
Note: If RJ-11 phone jacks are not used in your country, you
will need a phone adapter. Plug the adapter into the V3’s
PHONE jack and then plug in your phone.

3 Connect the V3 to the traditional telephone network.

Plug one end of the V3’s phone cord into the V3’s TELCO
jack and the other end into a telephone jack where you would
normally plug in a standard telephone. If you are using DSL,
this jack should have a DSL phone filter installed on it. Phone
filters block the DSL frequencies so that someone making a
normal phone call won’t hear noise on the line. They also keep
phone conversations from interfering with DSL performance.
If you do not have a DSL phone filter, they are available at
most retail stores that sell consumer electronics.

4 Connect the V3 to your cable or DSL modem.

Plug one end of an Ethernet cable into your cable or DSL
modem and plug the other end into the WAN port of the V3.
If your cable or DSL modem is already connected to your PC
with an Ethernet cable, leave the cable plugged into the cable
or DSL modem. Then, unplug the other end from the PC and
plug the end you just unplugged into the V3’s WAN port.

Chapter 1: Installation Instructions

5 If you have an existing router, we recommend that you

replace the existing router with the V3, which has a built-in
router. If, however, you need to connect the V3 behind
another router, plug one end of the Ethernet cable into the
WAN port of the V3 and the other end into a LAN port of
the router.

6 If you have a wireless access point or are using a wireless
router as an access point, unplug it from your computer or
modem and plug it into one of the V3’s LAN ports.

7 Connect the V3 to your computer. We recommend that you
use the Ethernet port if possible, because Ethernet provides a
more reliable connection.

Ethernet - Plug one end of the included Ethernet cable into
one of the V3’s LAN ports (1, 2, 3, or 4) and plug the other
end into the computer’s Ethernet port.
USB - Plug one end of the USB cable into the V3’s USB port
and the other end into the computer’s USB port.

Zoom V3 User’s Guide

Powering Up
To ensure that all the devices you just connected to the V3 install
correctly, you need to power up each device one at a time. Follow
these steps carefully.

1 Plug in the modem’s Power Supply, and turn on the
modem’s on/off switch if it has one.

Plug the modem’s power cube into a power outlet.
Wait for one-two minutes so that you are sure the modem has
completed its power up process before proceeding to Step 2.

2 Plug in the V3’s Power Supply.
Plug the included power cube into a power outlet and then
into the V3’s power (PWR) jack.
Wait for one-two minutes so that you are sure the V3 has
completed its power up process before proceeding to Step 3.
Note: Use only the power cube shipped with the V3 or you
may cause damage to your hardware.

3 Turn the computer on.
If you are using USB, a Found New Hardware box should
display, showing the progress of the installation. Follow the
prompts.
—Windows XP users: You may see Hardware Installation
disclaimer boxes regarding Windows logo testing. You can
safely disregard these messages and click Continue Anyway.
—Windows 2000 users: You may see a Digital Signature
Not Found dialog box. You can safely disregard this message
and click Yes.
—Windows 98/Me users: Restart your computer if you are
prompted to do so.

automatically, so you can skip this section. Turn to page 68 to
make sure that your computer’s TCP/IP settings are configured
correctly.
Windows users: The software that you use to make an Internet
connection must be set for a network connection, not a dial-up
connection. If you are already using a cable or DSL modem, you
shouldn’t need to do anything. If you are just setting up your cable
or DSL Internet connection for the first time, we have included
instructions. The following instructions are for Internet Explorer, a
popular Web browser. If you are using Netscape Navigator or
another browser, set it up now to use a network connection (this
might be called a “Local Area Network” or “broadband”
connection).
If you use Internet Explorer, you need Version 5 or later. Most
people have the right version. If you don’t, we suggest you get a
free upgrade. If you want to check your version number, open
Internet Explorer, select Help, then About Internet Explorer.
Your version number is right under the Microsoft Internet
Explorer logo. You can ignore all the numbers after the period
following the first digit.

Step 4: Configuring Your V3
•

If you have a Cable Modem, see below

•

If you have a DSL Modem, see page 15.

Configuring the V3 for a Cable
Modem
The V3 is set up by default to work with a cable modem, so
additional configuration is normally not required.

1 Go to your Web browser (i.e., Internet Explorer or Netscape
Navigator) and try to connect to a familiar Web address.

2 If you connect successfully, your installation is complete

and you’re ready to browse the Web! Continue with Step 5:
Setting up VoIP Service on page 18.

Zoom V3 User’s Guide

Configuring the V3 for a DSL
Modem

1 Open the Zoom Configuration Manager.

You should have a Zoom icon on your desktop. You must
double-click this icon to open up the Zoom
Configuration Manager. (If you do not have an icon,
open your Web browser, type http://10.2.2.2 and press
Enter.)

2 Log in to the Zoom Configuration Manager.

Type the following User Name and Password in lowercase
letters as shown. (You will need to use this User Name and
Password each time you want to open up the Zoom
Configuration Manager. See Changing the V3’s Password
in the User’s Manual on the CD if you would like to choose a
different Password.)
User Name: admin
Password: zoomvoip

Chapter 1: Installation Instructions

3 The Basic Setup page displays.
At Internet Connection Type, pull down the list of selections
and choose the type of DSL your provider uses. If you don’t
know what type you have, read below.
The three most common types of DSL service are PPPoE, PPPoA,
and 1483. There is also Static IP, but it is very unlikely that you are
using it without knowing. You would have had to ask your service
provider for it, and there is typically an additional monthly fee.
It is very important that this selection is correct, so if you don’t
know what type of service you have, we recommend that you call
your service provider and ask them. If you can’t call them, the
tables beginning on page should help you figure it out.

4 Click Save Changes. The screen may change slightly,
depending on the type of DSL you select.

Zoom V3 User’s Guide

5 Configuring the V3 for DSL PPPoE, PPPoA, 1483, or
Static IP.

If you selected DSL PPPoE:
Your service provider should have given you a username
(usually your email address or the characters preceding the @
sign in your email address) and a password (NOT the
username and password that you used to get into the Zoom
Configuration Manager.) If you cannot remember or cannot
find your username and password, call your service provider
and tell them you have misplaced your username and
password. Then enter them as well. Skip to Step 7.

If you selected DSL PPPoA or DSL 1483:
To make the V3 work with DSL PPPoA or 1483, you will have
to configure your DSL modem. For PPPoA, you need to “pass
through” your DSL modem’s IP Address to the V3. For DSL
1483, you need to “turn off NAT.” NAT is a kind of firewall.
You will have to do this through your DSL modem
configuration software. Unfortunately there are many different
DSL modem manufacturers and each one handles this a little
bit differently, so we can’t give specific instructions for your
modem. You should find these settings in your DSL modem
user’s manual or configuration software under “Advanced
Features” or “Advanced Configuration.”
—If you have DSL PPPoA, the setting that you are looking
for is commonly called PPP Half Bridge, ZIPB, DHCP
Spoofing, or just IP Passthrough. When you find it, check
or select it.
—If you have DSL 1483, look for Setting NAT, NAT
Configuration, or something similar. When you find it, turn
off NAT.

If you selected DSL with Static IP:
Enter the static IP address, subnet mask, default gateway,
and DNS Server IP address assigned to you by your service
provider, and then click Add.

Chapter 1: Installation Instructions

6 Click Save Changes, then Write Settings to Flash and
Reboot, and then Confirm.

7 Go to your Web browser (i.e., Internet Explorer or Netscape
Navigator) and try to connect to a familiar Web address.

8 If you connect successfully, your installation is complete

and you’re ready to browse the Web! Continue with Step 5:
Setting up VoIP Service
If you do not connect successfully, refer to the
Troubleshooting Tips on page 71.

Step 5: Setting up VoIP Service
If you purchased a V3 Model 5567, your unit has been set up for
VoIP service, so continue below with 1.3 Tips for Making VoIP
Calls. If you purchased another Model V3, please go to Chapter 2
on page 23.

1.3 Tips for Making VoIP Calls
Distinctive Ring and Dial Tone - The V3’s ring and dial tone
sound different from your normal phone. This means that you can
easily tell by the ring that you are receiving a VoIP call. Perhaps
more important, when you make a VoIP call, you will hear a
different dial tone than you hear on the public phone network, so
that you can be sure you are making a VoIP call.
Speed dialing - If the phone that you plugged into the V3 has a
speed dialing feature, you can use it for your VoIP calls and your
regular calls. Just be sure to start the VoIP calls with the # symbol
(except in VoIP Only Mode where you don’t use the #).
Redial - You may redial a VoIP number just as you would redial
any other number, using the redial feature on your phone.

Zoom V3 User’s Guide

Hook Flash - If you receive a second call while you are on a VoIP
call, you will hear a call waiting tone. Momentarily press the hook
button on your phone to talk to the second caller, and press it
again to go back to your first conversation. After you have
completed a VoIP call, you can press the hook button to get a
fresh VoIP dial tone and make another VoIP call without dialing #
(Note that redial or speed dialing will not work in this case,
however. You must hang up for at least one second if you need to
make a conventional phone call.

1.4 Setting the V3 for VoIP Only
Mode
For models outside of the US, the V3 can be set to operate in
VoIP Only Mode. While in VoIP Only Mode, you do not need
to dial # before dialing a number. Use VoIP Only Mode when:
•

You have a cable modem and you are not near a phone jack
that you can plug the V3 into.

•

You are using a DSL modem and your DSL line also provides
your ISDN service.

•

You are using “unbundled” DSL—that is, a line without any
telephone service attached to it.

•

You intend to use the phone connected to the V3 solely for
VoIP calls. That way, you do not have to hit # before every
call.

To put the V3 in VoIP Only Mode, follow these steps:

1 From the Zoom Configuration Manager, click the Voice
Over IP icon at the top of the page.

2 Check the VoIP Only Mode box.
3 Click Save Changes, Write Settings to Flash and Reboot,
and Confirm.

Chapter 1: Installation Instructions

If you have changed the system settings on your V3 unit and for
some reason want to restore them to the factory default settings,
you can do so in one of two ways: You can perform a software
reset or a hard reset.
If you can open your Web browser and access your V3’s user
interface, here’s how to perform a software reset:
•

From the Advanced Setup page, under Administration, click
Reset to Default. You will be prompted to click the Write
Settings to Flash and Reboot button. Once this process is
complete, your unit is reset to its factory settings. Click on any
of the icons at the top of the page to continue.

If you lose your link to the unit and cannot communicate with it
via the Web browser, here’s how to perform a hard reset.
•

Using a paper clip, press the RESET button on the unit’s back
panel. While holding in this button, count to five, and then
release the button. You are now guaranteed that all system
settings are restored to the unit’s factory defaults.

1.8 Windows Users: Removing
the V3
If you have Windows and want to remove your V3—for instance,
if you move your computer to a location without broadband
service—you should remove the software before disconnecting the
hardware.

1 From the desktop, select Start | Programs | Zoom VoIP
Gateway | Uninstall.

Voice Over IP Settings
If you purchased a V3 Model 5567, you do not need this
chapter. If you have another V3 model, please continue below.

2.1 Changing Your VoIP Settings
The V3 needs to be configured with specific information for
the VoIP service that you plan to use.
If you received the V3 from your service provider, it is likely
that it is preset for their VoIP service. In most cases the service
provider will tell you that the unit has been preset. If you’re not
sure you can check by going to the Advanced VoIP Setup page
(Double-click the Zoom V3 icon on your desktop, then the Voice
over IP button on the opening page, then the Advanced VoIP
Setup button.) If the User ID box is filled in, your V3 is preset;
you can now refer to Section 1.3 Tips for Making VoIP Calls
on page 18 or Section 2.2 Call Forwarding and Call Waiting
on page 28. If your V3 is not preset, continue below.

If Your Unit Is Not Preset for VoIP
There are two ways to configure the V3 for VoIP. Both require
that you enter specific information provided to you by your service
provider.
Some service providers use Auto Account Configuration. If your
service provider gave you a Server Address, they are using Auto
Account Configuration. Go to Auto Account Configuration on
page 24.

Chapter 2: Voice Over IP Settings

If your service provider did not give you a Server Address but
provided you with a User ID and a Password, you will configure
your V3 manually. Go to Manual Account Configuration on page
26.

Auto Account Configuration

1 Open the Voice Over IP page.
Click the Zoom V3 icon on your desktop, then the Voice over IP
icon at the top of the opening page to display the Voice over IP
setup page.

2 Under Basic Setup, in the Server box enter the Server
address given to you by your provider.

Zoom V3 User’s Guide

3 If your service provider gave you a Filename, enter it in
the Filename box. If you did not get a Filename from
your service provider, leave the box as it is.

4 Go to the box labeled Encryption. Your service provider

should have told you whether encryption should be on
(box checked) or off (box unchecked). It is important that
this is right, so if you don’t have this information contact
your service provider before proceeding.

5 Click the Download Configuration button.
6 You can now use Select Ring & Tone by

Country/Region to decide what kind of ring and ring
tone you would like for your incoming VoIP calls. You
can either choose to have your ring and ring tone be the
same as your normal phone ring, slightly different, or
completely different. We recommend that you make the
ring different from your normal ring so that you can tell
the difference between an incoming VoIP call and a
regular call.

To make your incoming ring the same as your normal
ring, choose your country from the pulldown menu.
To make your incoming ring slightly different from your
normal ring, choose your country from the pulldown menu
and pick the “VoIP” option. This will give you the same tone
as your normal ring with a different ring pattern.
For a completely different ring tone for your VoIP calls,
you can choose any ring listed for any country.

7 Click Save Changes, then Write Settings to Flash and
Reboot, and then Confirm.

Chapter 2: Voice Over IP Settings

8 Check that your settings are okay. Look at the User

ID box near the top of the page. If this box is now filled

they match the information given to you.

4 If you installed the V3 behind a router or your service

provider told you to enable STUN, click Yes to enable
STUN. Then, enter the STUN server name and port
number. These should have been given to you by your
service provider.

5 Enter any additional information required by your
service provider. If your provider gave you any other
information, enter it in the appropriate boxes.

You can now use Select Ring &Tone by Country/Region
to decide what kind of ring and ring tone you would like for
your incoming VoIP calls. You can either choose to have your
ring and ring tone be the same as your normal phone ring,
slightly different, or completely different. We recommend that
you make the ring different from your normal ring so that you

management features such as call forwarding and call waiting. Click
its button on the bottom of the Voice Over IP page.

Important: The V3’s call forward capabilities are displayed on this
page. However, to activate these functions, you must enter the
V3’s VoIP call management commands using your telephone
keypad. The section immediately following the table, Activating
Call Management Features, explains how to do this.

Enable Call Forwarding

Click to turn on the call forwarding feature.
Then select (click) the options listed below
that you want to use.

Forward Calls To

Enter the phone number of the location
where you want to forward incoming VoIP
calls. You must also enter the forwarding
number using your telephone keypad, as
explained below this table.

Forward All Calls

Enables the forwarding of all VoIP calls to
the specified forwarding number.

Forward When Busy

Enables the forwarding of VoIP calls to the
specified forwarding number when the V3’s
phone is busy.

Forward When No
Answer

Enables the forwarding of VoIP calls to the
specified forwarding number when there is
no answer.

Enable Call Waiting

Enabled by default.
Call waiting signals you with a tone when
another caller tries to contact you while you
are on the phone. Press the hook button on
your phone to be connected to the second
caller, and the person you were talking with
will be placed on hold. Press it again to
return to the first conversation. If you
disable it, callers will either hear a busy
signal or they will be given the option to
leave a voice mail message; this depends
on your service provider.

Enable Call Return

Enabled by default. Dial the call return
number for your region, preceded by the #
sign, if you want the V3 to dial the last
number that attempted to call you. if you do
not know the call return number or it does
not work, dial # and then * 6 9

Features
Note:
Call forwarding works only for calls that arrive over VoIP. The V3
cannot forward calls from the PSTN. However, if you have VoIP
to PSTN service, you can forward VoIP calls from the V3 to the
PSTN.
The command sequence to control call management is simple. We
have included a sample table below. On your telephone keypad,
enter
# #
The V3 will attempt to place a call to the Forward Number.
If someone answers within 15 seconds, the forwarding feature will
become active. If not, you need to re-enter the command:
# #
Then the forwarding feature you have selected will become active.
You will hear a stutter dial tone while call forwarding is active.

Playing Online Games
Setting up the V3 for online gaming depends on what you want
to do:
• If you have Xbox® Live, continue below.
• If you have PlayStation 2®, go to page 33.
• If you have another online game, go to page 35 .

3.1 Using Your V3 with Xbox®
Live
Follow these steps:

1 Update the Xbox Dashboard: Make sure you have your

Xbox Live Starter Kit at hand. Insert the Xbox Live CD into
your Xbox. Once the upgrade is complete, the main menu will
include an Xbox Live entry.

2 Connect the V3 and the Xbox: Using an Ethernet cable, plug
one end into the Xbox’s jack and the other end into one of the
V3’s Ethernet (LAN) jacks. Note: If you didn’t use the
Ethernet cable that came in your V3 package to connect the
V3 to your computer, you can use that cable. Otherwise, you
can buy one at your local electronics or computer store. Insert
the Xbox Communicator module into the Xbox Controller
expansion slot (top slot) and then insert the headset plug into
the Communicator module.

Zoom V3 User’s Guide

3 Activate your Xbox Live account: The Xbox Live CD

should still be in your Xbox. We recommend that you watch a
video that explains the installation process: Select Xbox Live
from the menu. Then, from the Dashboard, select Xbox Live
and follow the prompts. Note: You will need your
subscription code to activate your account—this number is
located on the CD’s sleeve. (If you require more detailed
instructions, please refer to your Xbox Live documentation.)

That’s it! You can load one of the demo games included on your
Xbox Live CD or use any other Xbox Live-enabled game to begin.

3.2 Using Your V3 with
PlayStation® 2
Your PlayStation 2 must be connected to your V3: Using an
Ethernet cable, plug one end into the PlayStation’s Network jack
and the other end into one of the V3’s Ethernet (LAN) jacks.
Note: If you didn’t use the Ethernet cable that came in your V3
package to connect the V3 to your computer, you can use that
cable. Otherwise, you can buy one at your local electronics or
computer store. Then follow the steps below.

1 Load the PS2 Network Adapter Start-up Disc that was

supplied with the PS2 network adapter into the PlayStation 2.

2 At the PlayStation’s main menu, select ISP Setup.

3.3 Setting Up the V3 for Peerto-Peer Gaming and Multiplayer
Game Hosting
There are only two cases where you need to set up your V3 for
online gaming.
— If you are using your computer to play a “peer-to-peer” or
“head-to-head” game over the Internet, you always have to
set up the V3 unless you linked up to your partner by going to
a web site. A peer-to-peer game is a game where two players
are competing directly against one another. Popular peer-topeer games include Age of Empires, Command and Conquer,
Dark Reign 2, and Unreal Tournament. If you are unsure
whether your game is a peer-to-peer game, check the game
instructions.
— If you are using your computer to play a multiplayer game
and you want to host the game. Popular multiplayer games
include Half Life, Diablo II, Delta Force, Hexen II, Myth,
Quake II, and Warcraft II, III.
In both these cases you will need to open one or more ports in the
V3’s built-in firewall as described below, so that the firewall doesn’t
block the other players. The two ways to accomplish this are to
Set up a Virtual Server if you only need to open a few ports, or
to Set up a DMZ, which opens all the V3’s ports.
Important!
If your computer already has firewall software installed:
If you have third-party firewall software installed on your
computer, such as the Windows XP firewall, you may need to
deactivate it before opening ports by setting up a virtual server or
a DMZ. If you don’t, your computer may block the ports you are
trying to open.
If you do not know how to deactivate the software, consult your
Windows Help or the documentation that came with your
software or computer.
• For Virtual Server instructions, continue below.
•

For DMZ instructions, go to page 44.

Chapter 3: Playing Online Games

3.4 Setting Up a Virtual Server

1 Find out which ports need to be opened for gaming.
Most peer-to-peer and multiplayer game manuals will tell you
exactly which port or ports need to be opened. If yours didn’t, you
may be able to look up the information at:
www.practicallynetworked.com/sharing/app_port_list.htm
If you have found your games port settings, we recommend that
you print them out, write them down now, or keep the game
manual handy.
Different games require different numbers of ports to be open.
This can be a single port, or it can be a hundred ports or more.
Each required port needs to be set individually, so the more
ports that your game requires, the more time it will take to do
the configuration. Some games even use “dynamic” ports,
meaning that the ports used by the game are constantly changing,
so you can’t set the ports.
There is a setting that opens all your ports for gaming, called a
DMZ. If you can’t find the port settings in your game manual or
on the web site shown above, or if you have to open more than 20
ports (which is the maximum allowed by the V3), or if your game
documentation says that the game uses dynamic ports, or if you
don’t want to spend the time to open multiple ports, refer to the
DMZ instructions on page 44.
Warning!
Every time you open an additional port, it decreases the
effectiveness of your firewall, so the less ports you open the better.

2 Choose an IP address for Gaming.
Double-click the Zoom V3 icon on your desktop (or type 10.2.2.2
in your Web browser just the way you would normally type a web
address) to get to the V3’s Zoom Configuration Manager. Click
the Advanced Setup icon, then click LAN Settings. There you
will see the starting and ending range of the V3’s dynamic (DHCP)
LAN IP addresses. You need to choose an IP Address that is
outside this range. Normally you should pick the next higher
number. For example, if the range shown is 10.2.2.4 to 10.2.2.15,
your Host IP Address should be the next IP address after
10.2.2.15, which would be 10.2.2.16. Unless you have changed the
V3’s IP address settings, which is very unlikely, just use that
number. Write down the number you choose for reference. The
rest of the instructions will assume that you are using 10.2.2.16.

7 All Users: Go back to the V3’s Advanced Setup page
and click the Virtual Server button.

If you already closed the Zoom Configuration Manager, doubleclick the Zoom V3 icon on your desktop (or type 10.2.2.2 in your
Web browser) and click the Advanced Setup icon.

8 Configure the Virtual Server.
This is where you’ll need to enter the information that you got
from your gaming manual or the
www.practicallynetworked.com web site. Unfortunately, you
can only configure one port at a time. Each time you configure
a new port, your computer will reboot when you hit Write
Settings to Flash and Reboot.
Tip:
If you have more than a few ports, this process could take a
long time. An option is to set up a DMZ, which opens all
your ports at once. See page 44 for instructions.

Chapter 3: Playing Online Games

Enter the information shown below now on the Virtual Server
Configuration page.

Public Port

Inbound port from the Internet that you want
to open. This is the port number, or one of
the port numbers, that you got from your
gaming manual or the web site at
www.practicallynetworked.com

Private Port

Enter the same port number that you
entered in the Public Port field above.
(Technically, the Private Port is the inbound
port from the V3 that you want to open to the
LAN side.)
Note: You cannot leave the Private Port field
blank.

Port Type

The default is TCP. Some games use both
TCP and UDP. If your game uses both port
types, you will have to create two Virtual
Server entries for each port you want to
open. Once you will have to enter the Public
Port, Private Port, and Host IP address, and
select TCP, and then you will have to fill in
the same fields again and select UDP.

Host IP Address

Fixed IP address of the host computer—this
is the same IP address that you chose in
Step 2 and entered in Step 4, probably
10.2.2.16.

Zoom V3 User’s Guide

9 After entering the above information, click Add This
Setting.

10 Click Write Settings to Flash and Reboot.
Your computer will reboot. If you need to open additional
ports, go back to Step 8 on page 41 and repeat.
Important:
Outside game players will need to know the V3’s WAN IP
address. To find this address, click the System Status icon at the
top of any Zoom Configuration Manager page and scroll down
to the WAN Status section.

Chapter 3: Playing Online Games

3.5 Setting Up a DMZ
If you are playing a game or using an application that requires a
specific port or ports to be open, go to page 36 for instructions
on setting up a Virtual Server. A virtual server can have a
maximum of 20 ports open.
If you need more than 20 ports open, or you don’t know which
ports to open (some games or applications like NetMeeting use
“dynamic” ports, meaning that the ports used by the game are
constantly changing, so it is not possible to set specific ports), you
have to set up what is called a DMZ (Demilitarized Zone).
To set up a DMZ, you need to make all four of the settings in the
chart below. You make these settings on the computer where you
set up the DMZ, no matter whether the computer is a Windows,
Macintosh, or Linux computer.
Important!
If your computer already has firewall software installed: If
you have third-party firewall software installed on your
computer, such as the Windows XP firewall, you may need to
deactivate it before opening ports by setting up a virtual server or
a DMZ. If you don’t, your computer may block the ports you are
trying to open.
If you do not know how to deactivate the software, consult your
Windows Help or the documentation that came with your
software or computer.

Using the V3’s Advanced
Firewall
This chapter describes the V3’s advanced firewall and the types
of protection it offers. If you are like most users, you probably
will not need to modify your firewall settings. If, however, you
are an administrator or an expert user who wants to customize
the firewall to protect a network against specific threats, you
should refer to this chapter.
You can think of the firewall as playing a role like that of a guard at
the gate of an ancient walled city. The guard has a great scroll,
which lists allowed and proscribed traffic. In one possible set of
rules, visitors may enter only if they show an invitation from a
citizen of the city. Children may not leave the city. The guard may
allow entry of carts of flour, but only for delivery to the bakery.
Any messenger who doesn’t know the password to the city is
thrown in the moat, and can’t pass through the gate.
You may set the policies of your firewall, which is like writing the
rules on the great scroll in the example. The firewall will then
follow the rules, acting like the guard. Instead of controlling entry
and exit of goods and people, you control entry and exit of
particular types of IP packets. In general, you will want to do this
to prevent unwanted packets from entering your network (this is
the purpose of the wall in the first place).

Zoom V3 User’s Guide

By default, the firewall will allow only those packets to enter that
you are likely to need; for example, in response to a request for a
web page, or as part of a VoIP call you make. You may want to
accept other, specific packets, perhaps to facilitate Internet gaming,
or because you want people outside your network to access a server
you have set up. You may want to prevent some users from
accessing the Internet at all.
To access the V3’s firewall settings, from the Advanced Setup
page, click the Firewall button. (If you have exited from the V3
and have forgotten how to establish communication with it, refer
to page 15.)

The main Firewall page displays.
Note: If you ever want to disable the advanced firewall, there is an
option to do so at the bottom of the page.

Chapter 4: Using the V3’s Advanced Firewall

4.1 Main Firewall Features
The V3’s (DoS) Denial of Service firewall features are grouped
together in the top section, under Advanced Options. These DoS
features mean that the V3 provides protection from a potentially
devastating attack on your computer. Such attacks can overwhelm
and shut down a computer or a server. The V3’s DoS features are
grouped together as follows:
•

Protection Policy

•

Hacker Log

•

Service Filtering.

Protection Policy
Click the Protection Policy link to display the basic and advanced
protections. Protection policies provide a defense from the most
common methods of tampering with the security of a network. All
the defense mechanisms listed below are enabled by default.

Zoom V3 User’s Guide

IP Spoof
checking

Inspects so-called “trusted” IP addresses to ensure
legitimacy.

Ping of Death
checking

Prevents oversized ping packet fragments (totaling
more than 65,536 bytes) from getting through—
which cause the computer to hang or crash.

Land Attack
checking

Guards against attackers who mimic source and
destination ports and IP addresses, causing infinite
loops and system crashes.

Reassembly
checking

Ensures correct reassembly of datagrams—
prevents attackers from sending a continuous
stream of identical, invalid datagram fragments that
can cause system state problems.

SYN
(synchronize)
Flooding
checking

Prevents attackers from flooding the system with
incomplete synchronization connection requests,
which can exhaust server resources and cause
operating system crashes.

ICMP
Redirection
checking

Keeps route information hidden, ensuring that ICMP
messages cannot be compromised, or forged, and
redirected to the attacker’s destination of choice.

Source
Routing
checking

Prevents attackers from illegally obtaining network
data by stipulating that data packets must follow
strict source routing.

Winnuke
checking

Only applicable to Windows 95, NT, and 3.11
systems. Prevents OOB (out of band) data from
reaching an IP address, which can cause lost
connections and system crashes.

Chapter 4: Using the V3’s Advanced Firewall

Hacker Log
Whenever the firewall prevents a packet from being delivered
because of a perceived security threat, the Hacker Log feature
keeps track. You have the option of specifying which types of
messages are logged in and displayed. Note: These options are
directly related to the Protection Policy page described above.

Alert Log

Click to add any of these types of
attacks—SYN Flooding, Ping of Death, IP
Spoofing, Win Nuke—to the log entries in
the system log of policy violations. (To
view the log, go to the Advanced Setup
page and click System Log.)

Log Database Properties
Log Frequency

You have the option of selecting how often
a particular type of hacker event can occur
before the V3 generates a system log
entry. The default is every 100 records or
events. Available range is 1-65535
records/events.

General Log

Click to add General Attacks, Deny
Policies, or Allow Policies to the log
entries in the system log of policy
violations. (To view the log, go to the
Advanced Setup page and click System
Log.) General Attacks are those most
likely to occur—Land Attack, Reassembly
Attack, ICMP Redirection, and Source
Routing. Deny Policy and Allow Policy are
tied to inbound and outbound firewall
policies (see page 56).

Zoom V3 User’s Guide

Once you’ve made your selections, click Save Changes and Write
Settings to Flash and Reboot.

Service Filtering
The Service Filtering feature lets you give certain users permission
to access the V3 from outside the network—that is, over the
Internet. If you enable one of the services listed on this page, the
V3’s firewall will open up the appropriate port to allow the service
to work.
PING from External Network

Disabled by default. Enable it
to allow an external user to
ping your V3. This can be
useful if you need to
troubleshoot your unit.

FTP from External Network*

Disabled by default. Enable it
to allow an external user to ftp
into your V3. Typically, you
would do this if you wanted
someone to check the V3’s
configuration.

DNS from External Network

Disabled by default. Enable it
to allow your V3 to accept DNS
requests from an external
source.

IKE from External Network

Disabled by default. Enable it
to allow a VPN (virtual private
network) connection to your
network.

RIP from External Network

Disabled by default. Enable it
to allow your V3 to receive RIP
(Routing Information Protocol)
requests from an external
source. The Technical
Reference Manual contains
details about RIP; go to
www.zoom.com

DHCP from External Network

Disabled by default. Enable it
to allow your V3 to receive
DHCP requests from an
external source.

Chapter 4: Using the V3’s Advanced Firewall

*Important: To complete the step of allowing remote users to
FTP into the V3, you must go to the V3’s Advanced Setup page,
click the Misc. Config. button, and do the following: Enable FTP
Server in the dropdown list and uncheck the box “Disable WAN
side FTP access.” FTP must be enabled in both places for this
feature to work.
Once you’ve made your selections, click Save Changes and Write
Settings to Flash and Reboot.

4.2 Creating Inbound/Outbound
Policies
The V3 offers ways to tailor, or restrict, incoming and outgoing
Internet traffic to increase security. Your V3 comes with three
inbound/outbound policies preconfigured for VoIP: 1) SIP Port
5060; 2) RTP Media Base 5000; 3) TFTP Port 60.
To create additional policies, from the main Firewall page, click
the Inbound Policy or Outbound Policy link, depending on
what you want to do.
Tip: When setting up policies, it may help to think of inbound
and outbound policies as mirror images of each other. In
each case, the source and destination IP addresses, subnet
masks, and ports are reversed. That is, for an inbound policy,
the source address appears on the WAN side, and the
destination appears on the LAN side; for an outbound
policy, the source is on the LAN side and the destination is
on the WAN side.

Zoom V3 User’s Guide

Inbound Policies
Inbound firewall policies allow you to filter the traffic that arrives
over the Internet—from the WAN side to the V3 LAN side—
based on rules that you set up.

Src IP

Source IP address to which this rule should
apply.*

Dest IP

Destination IP address to which this rule
should apply.*

Src Port

Source Port number to which this rule should
apply.*

Dest Port

Destination Port number to which this rule
should apply.*

Transport Protocol

Protocol to be used. Choices are All, TCP,
UDP, ICMP, AH, ESP, GRE.

Filtering Action

Choices are Allow or Deny.

Time Window
Filtering

Default is none. If you set up Time Groups
(see page 62), they appear in this list as
options.

Chapter 4: Using the V3’s Advanced Firewall

Short for Database. Default is none. If you set
up IP Groups or Service Groups (see page 60
and 62), they appear in this list as options.

*For each of these fields, choices are any IP address, a single IP address, an IP range,
or a mask range.

Once you have entered all applicable information, click Add
Inbound Policy. From the subsequent page that displays, you can
move or edit this policy using the Up, Dn (short for Down), Edit,
and Delete buttons. Important: The firewall applies all
inbound policies in a top-down order according to their location in
the policy table. Once you have completed the creation of your
rules, use the Up and Dn buttons to put them in order in the table
from top to bottom. You can always add an All policy at the
bottom of the list, so that if there are any packets that don’t match
any of the above policies in the list, they will be denied (if you set
up Deny All), or permitted (if you set up Allow All).

Outbound Policies
Outbound firewall policies allow you to filter the traffic that users
inside the firewall—on the V3’s LAN side—are allowed to send
out over the Internet—to the WAN side.

Src IP

Source IP address to which this rule should
apply.*
Zoom V3 User’s Guide

Dest IP

Destination IP address to which this rule
should apply.*

Src Port

Source Port number to which this rule should

*For each of these fields, choices are any IP address, a single IP address, an IP range,
or a mask range.

Once you have entered all applicable information, click Add
Outbound Policy. From the subsequent page that displays, you
can move or edit this policy using the Up, Dn (short for Down),
Edit, and Delete buttons. Important: The firewall applies
outbound policies in a top-down order according to their location
in the policy table page. Once you have created all your rules, or
policies, use the Up and Dn buttons to put them in order in the
table from top to bottom. You can always add an All policy at the
bottom of the list, so that if there are any packets that don’t match
any of the above policies in the list, they will be denied (if you set
up Deny All), or permitted (if you set up Allow All).

Chapter 4: Using the V3’s Advanced Firewall

4.3 Setting Up Firewall
Databases
The V3 includes options to set up databases of user information,
so you can create different combinations of user groups. Drawing
from these groups, or databases, you can then create and apply
certain inbound and outbound policies and restrict Internet traffic.
For example, if you don’t want your children accessing the Internet
during the day, you can set up a time group that blocks access from
8am to 5pm. For instructions on how to create inbound and
outbound policies, refer to the section above.
•

IP Group

•

Service Group

•

Time Group.

IP Group
The IP Group page lets you specify IP addresses and subnet masks
and assign a group name to them. That way, you can create a set of
inbound and outbound firewall policies pertaining to multiple
individuals simultaneously. For example, if you have a small office
and you don’t want certain computers (or users) to have Internet
access, you can set up an IP group that includes those computers
and then set up an outbound policy that blocks Internet access for
that IP group.

Zoom V3 User’s Guide

IP/Mask

There are three ways to use this database. Choices
are Single IP, IP Range, or Subnet Mask. Your
selection depends on whether you want to specify
one IP address for an entire group, a range of IP
addresses for a group, or a range of subnet masks
for a group.

IP Entry Name

Name of your choosing. Purpose is to identify the IP
group you want to set up. Maximum field length=19
characters.

IP addr.1

IP address that you want to assign to a group.
If you selected Single IP, enter that IP address here.
If you selected the IP Range option because you
want to designate a range of addresses, enter the
beginning of the range here and enter the ending
range in the IP addr.2 field.
If you selected the Subnet Mask option, enter the
desired IP address here and enter the subnet mask
in the IP addr.2 field. All addresses falling within that
subnet will be included in the group you set up.

IP addr.2

If you are using the Single IP option, this field is not
applicable.
If you are using the IP Range option, enter the end
of the IP address range here. Note: IP addr.1 has to
contain the beginning of the range.
If you are using the Subnet Mask option, enter the
subnet mask here. The subnet mask divides IP
addresses into groups. In the IP addr.1 field, you
must enter an IP address of the group that you want
in the database. All IP addresses within the same
group as the address in the IP addr.1 field will be
affected.
For example, if you enter the IP address 192.168.0.1
in the ip addr.1 field and the subnet mask
255.255.255.0 in the ip addr.2 field, the group will
include the addresses 192.168.0.1 to 192.168.0.255
(for a total of 255 addresses). If you enter the IP
address 192.168.0.1 in the ip addr.1 field, and the
subnet mask 255.255.255.240 in the ip addr.2 field,
the group will include the addresses 192.168.0.1 to
192.168.0.15 (a total of 15 addresses).

Chapter 4: Using the V3’s Advanced Firewall

Once you have filled in these fields, click Add/Modify this entry.
A new page displays, showing the new entry at the top, with two
buttons Modify and Delete. You can change or delete this entry at
any time. From this page, you can also add new entries.

Service Group
The Service Group page lets you specify a port and assign a group
name to it. This is useful if you want to identify a group by a
particular port. You can then use that service group when creating
an inbound or outbound policy.

Service Entry Name

Name of your choosing. Purpose is to identify
the group that you want to assign to a
particular port. Maximum field length=19
characters.

TCP/UDP

Specify which protocol this group should use,
TCP (Transmission Control Protocol) or UDP
(User Datagram Protocol).

Port #

Port number of your choosing that should be
associated with this group.

Time Group
The Time Group, or Time Window, page lets you specify a
particular time period and assign a group name to it. For example,
if you don’t want your children accessing the Internet during the
day, you can set up a time group that blocks Internet access from
8am to 5pm. Time windows are useful when configuring inbound
and outbound firewall policies for a particular group of individuals.
62

Zoom V3 User’s Guide

Time Window Name

Name of your choosing. Purpose is to identify
the group that you want to associate with a
given time period. Maximum length=19
characters.

Time Period

Starting and ending time window—day, hour,
minute, and AM or PM.

Appendix A
DSL Internet Settings Tables
You can use the information in these tables if you need help
making your DSL selection on page 16.
Many DSL providers use different settings depending on the
region in which they are operating, which is why there may be
more than one setting for your service provider. The setting for
your service provider labeled (1) is the most commonly used
setting and should be tried first. The next most common is
labeled (2), and so on. You may have to try more than one
setting, which is why it is better to get the correct setting from
your service provider if possible.
If your service provider is not shown, and the settings for
Service Provider Not Shown don’t work, try the settings for the
company that provides local phone service in your area.

VoIP Phone Installation
Options
Your V3 gateway makes it easy to make both VoIP calls over
the Internet and regular phone calls using your standard phone
service. You can plug a single telephone into the V3’s PHONE
jack. You may prefer to connect more than one phone to the
V3 so that you can make VoIP calls from other rooms. You
have a choice of two ways to accomplish this without running
wires.
• Plug Multiple Phones Directly into the V3
• Use Cordless Phones to Link to the V3
Each of these ways is very easy and virtually foolproof.

Plug Multiple Phones Directly into
the V3
If you want more than one phone near the V3—in a small office,
for example—you can use standard telephone adapters to connect
multiple phones. These adapters are called T-adapters or 2-jack
modular adapters; many people use them to plug in their answering
machines. You can plug in as many phones as you’d like. (If you
plug multiple phones directly into the V3, just be sure that when
you add up all their Ringer Equivalence Numbers (RENs), the total
is 5 or lower. Virtually all phones show the REN somewhere. Most
phones have a REN that’s 1 or lower.)

Use Cordless Phones to Link to the
V3
If you have a cordless phone that has more than one handset,
simply plug the base station into the V3—you can then make VoIP
and regular calls using all the handsets.
Note: If you have a wireless network that operates over the typical
2.4GHz frequency and you want to use cordless phones, it is best if
you use 900MHz or 5GHz phones; that way, you will minimize any
chance of interference.

Appendix C
Mac and Linux Users: Setting
TCP/IP Network Settings
If you are using the Linux operating system, or if you are using
a Macintosh computer, you must ensure that your computer’s
network, or TCP/IP, settings are configured correctly.
Otherwise, you will not be able to connect to the Internet.
Windows automatically configures your network settings, so
you don’t have to perform this task.
Linux users: Turn to page 69.
Macintosh users: Continue below.

Macintosh TCP/IP Settings
Depending on your Mac OS, the directions to configure your
Macintosh’s network settings will differ. For OS X, follow the
instructions below. Otherwise go to page 69.

For Mac OS X
1 From the Dock, choose System Preferences and then

Network to display the Network pane. (For OS X 3, you also
have to click the Configure button.)

2 From the Location: list box, make sure Automatic is
selected.

Linux TCP/IP Settings
The instructions for setting up boot-time DHCP vary dramatically
by distribution, so you may want to refer to your particular
version’s documentation.
Note: If you have more than one network card installed, you will
need to pick distinct Ethernet identifiers for each (eth0, eth1, eth2,
etc.). If you select an identifier other than eth0 for your ADSL
modem, use that identifier throughout.

Appendix C: Macintosh and Linux Users: Setting TCP/IP Network Settings 69

For RedHat
Edit or create /etc/sysconfig/network-scripts/ifcfg-eth0 so
that it contains the following three lines:
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp

For SuSE
Edit the file /etc/rc.config; search for the variables
NETCONFIG, NETDEV_0, and IFCONFIG_0.
Set them as follows (see the instructions in rc.config):
NETCONFIG="_0"
NETDEV_0="eth0"
IFCONFIG_0="dhcpclient"

Reboot with this command: /sbin/shutdown -r now.

For Debian
Add this line to the file /etc/network/interfaces: iface eth0 inet
dhcp. Reboot with this command: /sbin/shutdown -r now.

Troubleshooting
Our Technical Support staff is ready to help you with any
questions you may have. However, if you are having trouble,
you may find an easy solution below. Otherwise, refer to the
Frequently Asked Questions (FAQs) on the CD (click Support),
Support
or visit our web site for the latest tips: www.zoom.com

Connection Troubleshooting Tips
In order to troubleshoot your Internet connection problem, we
recommend you first determine if the V3 has a WAN IP address or
not. The first tip below tells you how to determine if you have a
WAN IP address. Depending on your answer, we will recommend
other troubleshooting steps you should take to solve the problem.

If you can’t connect to the Internet, first make sure that
you have a WAN IP address:
Go to the V3’s System Status page and click WAN Status.
You should see a WAN IP address listed.
To get to the V3’s System Status page, double-click the
Zoom icon on your desktop (or type 10.2.2.2 in your Web
browser).
Then log in by entering the User Name admin and the
Password zoomvoip, and click the System Status icon.

Appendix D: Troubleshooting

If you have a WAN IP address, skip to page 72.
If you don’t have a WAN IP address and you are using a
Cable Modem or a DSL PPPoA or 1483 Modem, your
next step should be to do a Release/Renew operation.

1 Go to the V3’s Advanced Setup page and click WAN
DHCP Status.

2 Select Release and click Save Changes.
3 Select Renew and click Save Changes.
4 Go to your Web browser (i.e., Internet Explorer or

Netscape Navigator) and try to connect to a familiar Web
address. If you are unsuccessful, check to see if you have a
WAN IP address (see page 71). If you do not, you should
contact Zoom Technical Support.

If you have a WAN IP address, but can’t connect to the
Internet, make sure that:
Your Ethernet or USB cable connections are okay.
Check that the appropriate V3 front panel light is lit (LAN 1,
2, 3, or 4 or USB). This will confirm that the connection is
good.
Your WAN connection is okay.
Check that the V3 front panel LINK light is lit. This will
confirm that the connection to your cable or DSL modem is
good.
Your computer’s TCP/IP properties are correct.

VoIP and Phone Troubleshooting
Tips
When I pick up the phone and press #, I don’t get a VoIP dial
tone.
•

Your V3 may be in VoIP only mode. If so, you shouldn’t press
# to begin a call. See page 19 for instructions on changing
modes.

•

Your Internet Protocol connectivity may not be working. Try
browsing the Internet. If you can’t, refer to the Connection
Troubleshooting Tips above.

•

Check that your VoIP service is properly configured.

Appendix D: Troubleshooting

—If your service supports automatic configuration downloads,
go to the V3’s VoIP page to see if the V3 has received a
configuration download. If not, press the Download
Configuration Now button, or reboot the V3.
—If your service doesn’t support automatic configuration
downloads, double-check all the settings for your account
and service provider on the VoIP page and Advanced
VoIP Setup page. Check the User ID, Authorization ID,
Password, Domain/Realm, and SIP Proxy Address in
the appropriate boxes. These five boxes must be filled in
correctly. Also check with your service provider to see if
STUN should be enabled. If so, enable STUN and enter a
server and port address.
If none of the above helps, contact your VoIP service provider
When I try to make a VoIP call to another VoIP phone, the
call doesn’t go through.
The person or persons you are calling may not be available. Try
again later. Or, if there is a chance you may have the wrong
number, go to the provider’s Web site and check the directory.
Check if the person you are trying to call uses the same VoIP
service as you. If not:
•

You will have to precede your call by dialing a code for that
person’s VoIP service. Ask the person you are attempting to
call for the code, or check the service provider’s web site for a
list.

•

In some cases, there may not be a way to make direct VoIP
calls from your service to people subscribing to another VoIP
service. Check the web site, or email your provider.

When I try to make a VoIP call to a standard PSTN number,
the call doesn’t go through.
Make sure that:
•

You have signed up for PSTN service with your VoIP service
provider. Contact your provider’s customer support
department if necessary.
Zoom V3 User’s Guide

•

You are dialing according to the guidelines your service
provider gave you. Your provider’s web site should provide
instructions and examples. For instance, you may need to dial
local calls as though they were long distance. Or, you may need
to dial a call within your country as though you were calling
from outside the country—beginning with an international
prefix such as 00, followed by the country code, city code or
area code, and local number.

•

You aren’t taking too long between digits when you dial a
number. If you take a very long time, the V3 may register that
you have completed dialing before you are through. If this is a
possibility, hang up and try again.

When I pick up the phone, I don’t hear a dial tone.
For aV3 used normally, the dial tone you hear when you first pick
up your phone comes from the local phone company. Check that:
•

You have installed any phone adapters required for your
country.

•

Your TELCO line is firmly plugged into the telephone wall
jack.

If you have another phone jack for the same phone line, plug your
phone into that jack and make sure you hear a dial tone. If you
don’t, contact your local phone service provider. If you do, then
check that:
When some people call me, my Caller ID display doesn’t
work.
Some phones that display caller ID are very sensitive to ring type.
If you are using the VoIP version of the ring and tone sounds but
find that the Caller ID display on your phone is unreliable, try
switching back to the standard ring and tone configuration. See
page 25 for instructions on changing your ring.
The Caller ID setting may not be set to the right value for your
phone. You have one of two choices, Bell 212 or V.23. Go to the
V3’s Advanced Voice page and click the Advanced VoIP Setup
button to check your setting.
Appendix D: Troubleshooting

Your service provider may not pass through caller information for
all calls, in particular, DID calls to your VoIP connection that
come from the PSTN. Check with your provider’s customer
support.
My phone’s ring sounds strange.
If you don’t like the ring for incoming VoIP calls, you can change
it. Go to the V3’s VoIP page and click Select Tone & Ring by
Country/Region (see page 25 for instructions on changing your
ring). Note: Some country selections include two choices, one of
which is a special VoIP ring. This ring sounds a little different from
the standard ring for that country or region.
When I start to dial, I sometimes forget whether I’m dialing
over the PSTN or over the Internet (VoIP).
The V3 has a distinctive, lower-pitched dial tone when it is in VoIP
mode, compared to the standard phone dial tone for your country.
If you do not notice the V3’s change in dial tone after you press #
to begin a VoIP call, we recommend that you change your VoIP
dial tone to make it more easily recognizable. See page 25 for help
changing your ring tones.

This equipment contains an FCC compliant modular jack. It is designed to be connected to
the telephone network or premises wiring using compatible modular plugs and cabling
which comply with the requirements of FCC Part 68 rules.
The Ringer Equivalence Number, or REN, is used to determine the number of devices
which may be connected to the telephone line. An excessive REN may cause the equipment
to not ring in response to an incoming call. In most areas, the sum of the RENs of all
equipment on a line should not exceed five (5.0).
In the unlikely event that this equipment causes harm to the telephone network, the
telephone company can temporarily disconnect your service. The telephone company will try
to warn you in advance of any such disconnection, but if advance notice isn't practical, it
may disconnect the service first and notify you as soon as possible afterwards. In the event
such a disconnection is deemed necessary, you will be advised of your right to file a
complaint with the FCC.
From time to time, the telephone company may make changes in its facilities, equipment, or
operations which could affect the operation of this equipment. If this occurs, the telephone
company is required to provide you with advance notice so you can make the modifications
necessary to obtain uninterrupted service.
