1. Welcome
Overview
Congratulations on purchasing the 2-Port Gateway!
The 2-Port Gateway is a LAN router and Voiceover
Internet Protocol (VoIP) broadband device that
allows you to connect two analog phones for
simultaneous outgoing calls over the Internet using a
single Ethernet Local Area Network (LAN)
connection. The 2-Port Gateway converts the analog
signal from your telephone(s) to Voice over Internet
Protocol (VoIP). It then uses the LAN’s broadband
connection to send calls over the Internet via
Net2Phone’s service platform. Since Net2Phone
calls bypass most of the Public Switched Telephone
Network (PSTN), the result is significant savings on
long-distance communications services.
The 2-Port Gateway’s broadband router functionality
enables you to share a high-speed Internet
connection such as DSL/cable for use with multiple
computers/IP devices.
The 2-Port Gateway features several proprietary
Quality of Service (QoS) enhancements, including:
?? G.168 echo cancellation
?? Voice Activity Detection (VAD)
?? Comfort Noise Generation (CNG)
?? Dynamic jitter buffer control

2-Port Gateway User’s Guide

Product Features
Designed for versatility and performance, the 2-Port
Gateway provides the following features:
?? One 10/100 Mbps WAN port for connecting
a call agent
?? One 10/100 Mbps LAN port for connecting
to a local network
?? One analog POTS (Plain Old Telephone
System) interface for a PSTN “Life Line”
?? Two phone ports to allow two analog phone
connections for simultaneous outgoing calls
?? Silence Suppression to reduce bandwidth
consumption
?? Dynamic Host Configuration Protocol
(DHCP) or Static IP address assignment
?? Comfort Noise generation for more natural
experience
?? Adaptive jitter buffer for smooth voice quality
?? Remote software downloading/updating
?? Supports all normal phone features including
call waiting, call forwarding, and Caller ID
?? PSTN switchover in case of a power failure
or network breakdown
?? Intelligent dialing mode from IP/PSTN call
alteration via configurable hot key (#key is
the default)

2-Port Gateway User’s Guide

?? Actively listens for incoming calls from the
PSTN and rings on connected phones when
a call comes in on the PSTN Life Line port
?? Users can utilize the same phone for PSTN
and Internet phone calls; an incoming call on
the Life Line port will ring on the phone
connected to the 2-Port Gateway

?? Ethernet LAN Link/Activity LED –If the LED
is continuously illuminated, the connection
made through the corresponding port is
successfully running in full Duplex mode. If
the LED is flickering, it means the
connection is experiencing collisions.
Infrequent collisions are normal. If this LED
is flickering too often, there may be a
problem with your connection. Check

2. Getting Started
Overview
The Getting Started section details the hardware
requirements for proper installation of the 2-Port
Gateway, as well as instructions for connecting the
2-Port Gateway to your broadband connection, your
PC, and your phone lines. This section also
describes how to obtain an IP address, if needed, for
use in configuring the 2-Port Gateway.
Hardware Requirements
To use the 2-Port Gateway, you will need:
?? One A/C power adapter (included)
?? A broadband Internet connection, such as a
DSL or cable modem, a T1 line, etc.
?? One Net2Phone multi-user account number
and PIN on each port, or one single-use
Net2Phone account per port (available from
your distributor)
?? A PC workstation with any recent Web
browser, connected to the LAN port to
configure the device
?? If your WAN uses static IP addresses, you
will also need: an IP address, Netmask, and
gateway address for the 2-Port Gateway (all
available from your broadband service
provider)

Setting Up Your 2-Port Gateway
Your 2-Port Gateway can be used as a router to
connect up to 253 additional devices (such as PCs
or hubs) to create a LAN environment, as well as a
VoIP device allowing you to connect two analog
telephones to place inexpensive calls over the
Internet.
While one of the primary functions of the 2-Port
Gateway is as a router, you can choose to use it as
a VoIP device only. This chapter describes how to
set up the 2-Port Gateway to perform both functions.
You will perform the following basic, high-level steps,
which are outlined in more detail starting on page
10:
1. Install the 2-Port Gateway in its location and
connect the cabling.
2. Connect your PC to the 2-Port Gateway.
3. Reboot your PC and verify that the 2-Port
Gateway is accessible.
4. Log into the 2-Port Gateway’s Web
Management Tool to configure your WAN
and LAN settings as necessary (i.e., change
Point-to-Point Protocol over Ethernet
(PPPoE) and Static/DHCP settings, if
necessary).
5. Input your Net2Phone account(s) via the
Web Management Tool.
6. Reboot the 2-Port Gateway.

2-Port Gateway User’s Guide

Whether you choose to use your 2-Port Gateway as
a router or a VoIP device, the initial configuration,
shown below, is the same.
Note: Do not be concerned if you do not
have Internet connectivity at this point.
This issue will most likely be resolved
once you configure the 2-Port Gateway
based on your broadband WAN setup.
Note: If you are planning on using the
2-Port Gateway as a router to connect
multiple PCs and/or IP devices, then
you will connect the hub to the 2-Port
Gateway’s LAN port and then connect
your PC to the hub.
Note: If you are planning on using the
2-Port Gateway as a router to connect
multiple PCs and/or IP devices, then
you will connect the hub to the 2-Port
Gateway’s LAN port and then connect
your PC to the hub.

2-Port Gateway User’s Guide

To set up the 2-Port Gateway:
1. Connect the WAN port on the back of the 2-
Port Gateway (shown in the figure on the
next page) to your broadband/DSL/cable
modem or existing LAN broadband
connection (i.e., office network) via an RJ-45
cable.
2. Connect the LAN port on the 2-Port
Gateway to your computer or a hub that
routes to your PC via an RJ-45 cable.
Note: If you connect a hub to the
LAN port, then you must connect your
PC to the hub.

2-Port Gateway User’s Guide
11
3. Connect your phone(s) to the Phone 1jack
(and Phone 2jack if you are using two
phones).
4. Optional: To set up the ability to place calls
using your regular telephone line (PSTN) in
case of power outages or if your broadband
service provider is down, connect an analog
phone line (via an RJ-11 cable) to the Line
jack in the back panel of the device. For more
information on placing and receiving regular
(PSTN) calls on the 2-Port Gateway, see
Section 5, Placing and Receiving Calls.
5. Connect the AC Adapter cord to the back of
the 2-Port Gateway and plug in the power
cord.
Your cable connections should now
resemble the diagram on page 9.
6. Reboot your PC after all the cables have
been installed in order to obtain an IP
address from the 2-Port Gateway.
7. Once your PC has rebooted, you should be
able to connect to the 2-Port Gateway’s
Web Management Tool by entering the
following address into your PC’s Web
browser: http://192.168.100.1
Note: Do not be concerned if you do
not have Internet connectivity at this
point. This issue will most likely be
resolved once you configure the 2-
Port Gateway based on your
broadband WAN setup.

2-Port Gateway User’s Guide
12
If you are able to connect to 198.162.100.1 via a
Web browser from your PC, then you are ready to
configure the 2-Port Gateway. Please proceed to
Section 3, Configuring Your 2-Port Gateway.
If you cannot connect to 192.168.100.1, then you
need to verify that all of your cabling is properly
connected. If all of the connections are secure, then
you need to obtain an IP address for your PC using
MS-DOS (see below).
Obtaining an IP Address for Your PC
After rebooting your PC, if you are unable to
connect to the Web Management Tool from your
PC, you can manually direct your PC to connect
to the 2-Port Gateway to obtain an IP address.
To manually obtain an IP address:
1. On your Windows task bar, click the
Start menu button:
The Start menu displays.

2-Port Gateway User’s Guide

2. Click Run to access the Run window:
The Run window opens.
3. Type COMMAND in the Open field and
click the OK button.
The DOS prompt window displays.
Note:If COMMAND does not work, try
typing CMD.
4. From the DOS C:\> prompt, type:
ipconfig /renew
(Remember to include the space
between “ipconfig” and the “/”).

2-Port Gateway User’s Guide

Your PC will obtain an IP Address from
the 2-Port Gateway. The IP address will
start with 192.168.100.XXX.
Once you have obtained an IP address for the
PC from the device, you are ready to begin
configuring the 2-Port Gateway using the Web
Management Tool. Please continue to Section 3,
Configuring Your 2-Port Gateway.
