Lseries VoIP Gateways are the low to high VoIP total Solutions. This document describes
the usage of the Voice gateway.
1.1 Overview
VoIP Gateway which is a device that allows one to connect a normal PSTN telephone to the
Internet in order to make or place telephone calls.
VoIP Gateway device may work in conjunction with a computer, such as an IP-sharing /
Router, or it may be a stand-alone device that communicates with a service provider over the
Internet.
VoIP Gateway provides a direct analog interface for computer modems, fax machines, analog
telephones, and other devices that require an analog port.
2/4/8 port Series VoIP Gateway can build in a simple H.323 Gatekeeper or SIP Proxy Server.
VoIP Gateway also support standard Internet services, such as IP-Sharing, NAT, Virtual
Server, DDNS, QOS, Port Filter, IP Filter function.

2.3.3 Web User Interface
The gateway has a built-in HTTP(Web) server for configuration. Before you use the gateway to
access the Internet, you should set up a management PC to log into the router for further
configuration. The management PC may be configured with a fixed or dynamically assigned IP
address. For a fixed IP address, use an IP address from a 192.168.1.0/24 network, such as
192.168.1.10.
For a dynamic IP address, you need to set the PC as a DHCP client, and then restart or renew
the network settings. The DHCP server of router is enabled by default so the PC will then be
assigned an IP address and related settings by the router. The following examples are for a
MicrosoftTM Windows 2000/XP machine set to use a dynamic IP address.
Checking the Network IP Configuration
The following explains how to setup the Transmission Control Protocol/Internet Protocol
(TCP/IP) in Windows 2000/XP. For more detailed information on TCP/IP setup, refer to the
Windows 2000/XP help files. For other operating systems refer to the user manuals.
1. On the desktop, Please enter start -> control panel -> network setting.” Click Properties. The
Network screen will open.

18
(Your particular system will be different from the screen shown here.)
Check that you have an Ethernet network card installed. If not, refer to the card manufacturer’s
documentation and install the card and drivers.
If your card is installed,
1. Click the Add button. The Select Network Component Type dialog box will open. The box will
show four options: Client, Adapter, Protocol, and Service.
2. Select Protocol and click the Add button. The Select Network Protocol dialog box will open.
3. Select Microsoft in the left scrolling window then selects TCP/IP in the right, and click OK.”.
You will be returned to the Network dialog box.

19
Configuring the TCP/IP Protocol
1. On the Network dialog box Configuration card, select TCP/IP and then click Properties.” The
TCP/IP Properties dialog box will open.
2. On the IP Address tab, click Obtain an IP address automatically. As the DHCP (Dynamic Host
Configuration Protocol) server built into the router is enabled by default, your computer will get an
IP address, subnet mask, and other related IP network settings from the router.
3. On the DNS Configuration tab, click Disable DNS”.
4. Click the Gateway tab.
5. Make the New gateway and Installed gateways fields blank and click OK. A dialog box will pop up
asking you to restart the PC. Click Yes”.
Checking TCP/IP settings
1. After completing the previous steps, click Start -> Run -> and type ipconfig /all. The IP
Configuration window will open. If the PC does not show an IP address in the 222.222.222.51 to
222.222.222.100 range, click the ipconfig /release button to release the current configuration.
Wait a few seconds and click “ipconfig/renew” to get a new IP configuration from the router.
2. If the IP configuration is correct, you will be able to use the PING diagnostic utility built into
Microsoft Windows to ping the router. Click Start -> Programs -> MS-DOS Prompt. A command
mode window will open.Type “ping 222.222.222.1” (default IP of the router) to check the network
connectivity. If both hardware and software are correct, your computer will receive a response
from the router as shown on the next page. If not, verify that the Ethernet cable is connected to
the router properly and the Ethernet port LED on the front panel is lit.

20
Connecting to the Web Configuration via a Web Browser
1. Launch the Web browser(IE or Firefox). Enter http://222.222.222.1 into the browser Address
window and press the Enter Key
2. An authentication dialog box will open.
3. If this is a first time setup of the router, type “admin” as the User Name and the Password field
as “admin”. Click OK.(Default username/Password is “admin”)
