Plug one end of the RJ-11 telephone line into the PHONE port and plug the other end
into the phone socket of a telephone set.
3. PWR Port:
Plug one end of the power adapter into the PWR port and plug the other end into an
electric outlet in the wall.
Warning
Use only the enclosed power adapter accompanying the gateway device. Faulty or
improper voltage input may cause permanent damage to the power supply and the
gateway device thereby voiding the warranty.
4. ENET Port:
Plug one end of the RJ-45 Ethernet cable into the ENET port and plug the other end
into the Ethernet socket of the Network Interface Card (NIC) in the user’s PC.

Administrator Guide – AzaCall200 VOIP Multi-Protocol Gateway
8. WAN Port:
¾If the user has a cable modem…
zWithout an NAT Device between cable modem and the gateway device
Plug one end of the 8-wire, RJ-45 Ethernet cable into the WAN port of the
gateway device and plug the other end into the Ethernet port of the cable
modem. Then connect the cable modem using a twist-on, coaxial cable to the
matching socket in the wall.
zWith an NAT between cable modem and the gateway device
In contrast to the without-NAT scenario above, please first connect the gateway
device to the NAT device using an RJ-45 cable, then connect the NAT device to
the cable modem with an RJ-45 cable. The connection between cable modem
and the wall socket remains the same as before. Please refer to Figure 1 for
details.
Figure 1 Connectivity diagram for cable modem with NAT device

4
Administrator Guide – AzaCall200 VOIP Multi-Protocol Gateway
¾If the user has an ADSL Modem…
zWithout an NAT device between ADSL mode and the gateway device
Directly plug one end of an 8-wire, RJ-45 Ethernet cable into the WAN port of
the gateway device and plug the other end into the Ethernet port of the Internet
service device, such as an ADSL modem. Then connect the ADSL modem to the
modem port of the splitter using a 2~4 wire, RJ-11 telephone cable.
zWith an NAT device between ADSL modem and gateway device
In contrast to the without-NAT scenario above, please first connect the gateway
device to the NAT device using an RJ-45 cable, then connect the NAT device to
the ADSL modem with an RJ-45 cable. The connection between ADSL modem
and the splitter remains the same as before.
Figure 2 Connectivity diagram for ADSL modem with NAT device
Note
For LINE port connection, please connect to phone port of splitter using
RJ 11 cable, and then connect splitter to phone socket on wall via RJ 11
cable, too.

Administrator Guide – AzaCall200 VOIP Multi-Protocol Gateway
¾If the user has a fixed IP address from a service like Metro-Ethernet…
zWithout an NAT device between gateway device and Ethernet wall socket
Plug one end of the RJ-45 Ethernet cable into the WAN port of the gateway
device and plug the other end directly into Ethernet socket in the wall.
zWith an NAT device between gateway device and Ethernet wall socket
In contrast to the without-NAT scenario above, please first connect the gateway
device to the NAT device using an RJ-45 cable, then connect the NAT device to
the Ethernet wall socket with an RJ-45 cable.

2.3. Powering Up & Initialization
2.3.1. LED Status
1. When plugged into the appropriate electrical outlet, the gateway device will automatically
launch its self-diagnostic process. Three indicator lights (LED): PWR, WAN, and ENET,
will light up steadily. Wait for about 15 seconds for the device to complete this process.
When initialization is complete, the PWR LED will light up steadily, and the following
lights: WAN, ENET will also light up depending on how the physical connection is
established.
2. With all the data cables properly connected to the gateway device, user can observe the
front panel light status to determine the current device status. The table below shows the
possible indicator light statuses and their associated device statuses.

Firmware or configuration file is downloading from a network
server. Please do not turn off the device power during this
period.
ON OFF Out of service or boot code is not functioning properly.
Please power off and on the device again, and wait for about 3
minutes. If the LED status remains the same, please refer to
section on configuration for additional steps to take.
9. If the VOIP LED is lit up steadily and VOIP calls can be made, stop here. If not, proceed
to the configuration steps below.
Note
The configuration information presented here will help the users set up their
gateway devices in the most commonly seen network environments. More detailed
configuration information will be presented in the chapter titled “Configuration
Using Web-Based Interface”.

Equipment Overview
Our equipment device is a VOIP Gateway that delivers voice information over the Internet
instead of the traditional telephone network. This benefits small offices and work-at-home users
having high-speed Internet access by allowing them to use many service providers that offer toll-
free or low-cost voice services. In addition, the VOIP Gateway features a PSTN back-up line,
allowing users to still use the PSTN phone line should the VOIP service become unavailable,
such as when there is a power outage. Equipment configuration via Graphical User Interface
(GUI) is also available, allowing users to easily configure the equipment and software settings
via a web browser like the Internet Explorer. Firmware upgrade via TFTP is also supported,
allowing users to easily add newer and more powerful features to their gateway devices.
3.1. Introduction
The AzaCall200 gateway device is an external stand-alone device, which can provide a cost-
effective long-distance voice communication solution using the Internet. The gateway device can
establish a voice channel by adopting Voice Over Internet Protocol (VOIP) signaling schemes
after registering itself with a designated proxy server. The gateway device can be connected
directly to phones, fax machines, PBXs, and the Internet without any additional accessories or set
ups. When the Ethernet port of the gateway device is connected to another device with a WAN
interface (e.g. ADSL modem), the gateway device can provide toll quality voice communication
in terms of voice quality and reliability for the users.
Also, the gateway device integrates two kinds of data service modes, offering convenience and
flexibility to users. One such mode is the Gateway mode, and the other is the Transparent Bridge
mode. The Gateway mode targets users who have been enjoying high-speed Internet access
service from an ISP, but would like to add an additional subscription to VOIP telephony services.
The gateway device would be deployed to the subscriber’s home, with ADSL service feeding into
the device’s WAN port, and the LAN port connected to the subscriber’s equipment. In this
scenario, the gateway device delivers both voice service, as well as data routing function found in
a broadband router.
