1. Introduction
Product Overview
The NetComm SmartVoice series of stand-alone VoIP Gateways carry both voice and facsimile over
an IP network. They support the SIP industry standard call control protocol to be compatible with free
registration services or VoIP service providers’ systems and they work in two different modes: UA (User
Agent) or Server. As a standard user agent, the gateways are compatible with all well-known Soft
Switches and SIP proxy servers. With optional server software, the gateways can also be configured to
establish a private VoIP network over the Internet without a 3rd party SIP Proxy Server.
Each of the SmartVoice series VoIP gateways have a different combination of FXS and FXO ports; FXS
ports are used to connect directly to a telephone set and FXO ports are used to connect directly to PSTN
lines. There are a number of SmartVoice Gateway models available with 4 ports, 8 ports, 16 ports and
32 ports combinations. The gateways can be seamlessly integrated into existing networks by connecting
to a phone set, PBX, key telephone system, fax machine or PSTN line. With only a broadband connection
such as an ADSL bridge/router, Cable Modem or leased line router, the gateways allow you to gain
access to voice and fax services over an IP network thereby reducing the cost of international and long
distance calls.
In addition, each gateway includes an in-built 4 port Ethernet switch which supports comprehensive
Internet gateway functions to accommodate other PCs or IP devices to share the same broadband
stream. The QoS function allows voice and data traffic to flow through at the highest priority. and with
TOS/DiffServ bit enabled, it guarantees that voice packets will have the first priority to pass through a
TOS/DiffServ enabled router.
With the support of DDNS, the gateways are reachable by a domain name where the IP address is
dynamically assigned by the ISP, thereby allowing users to host a web site or mail server in a PPPoE or
DHCP network.
Each gateway can be assigned with a fixed IP address or by DHCP, PPPoE, adopting the G.711, G.726,
G.729A or G.723.1 voice compression format to save the network bandwidth while providing real-time
and toll quality voice. In addition, in the event that the power supply fails or the Internet connection is
lost, each gateway can divert the FXS lines to the PSTN network on the FXO ports so that users can still
use their conventional PSTN line to make calls.
IMPORTANT SAFETY INSTRUCTIONS
• When using your telephone equipment, basic safety precautions should always be followed
to reduce the risk of fire, electric shock and injury to persons, including the following:
• Avoid using a telephone (other than a cordless type) during an electrical storm. There
may be a remote risk of electric shock from lightning.
• Do not use the telephone to report a gas leak in the vicinity of the leak.
• Use only the power cord indicated in this manual.

Network Connections
Possible network connections are divided into 3 basic modes as described below:
• Gateway can be assigned with a Public IP Address
• Gateway can be installed under the existing NAT
• Gateway can be assigned with a Public IP address and serve as an IP sharing router.
Gateway Assigned with a Public IP Address
The VoIP gateway will have a Public IP address for its Internet connection regardless of whether it is a
static IP address, DHCP (using a Cable Modem), or PPPoE (Dialup / ADSL).
The following diagram shows a typical network connection in which broadband devices, such as an ADSL
router or Cable modem, need to work in bridged mode so that the gateway is able to obtain a public IP
address either through PPPoE, DHCP or static IP.
Gateway IP Settings Need to be set up as static IP, DHCP, or PPPoE
NAT/STUN Settings Unnecessary (Disabled)
DDNS Settings Unnecessary (Disabled)
Note: The above diagram shows a 4-port SmartVoice gateway for illustration purposes.
An 8, 16 or 32 port SmartVoice gateway could also be used depending upon your
network requirements.

Gateway behind a NAT/Firewall Network
The VoIP gateway uses a private IP address and the Internet sharing function of other systems to connect
to the Internet.
The following diagram shows a typical network connection in which broadband devices such as an
ADSL router work in router (NAT) mode so that the gateway is behind a NAT/Firewall. In this case, the
broadband router (NAT/Firewall) and the gateway need to be configured correctly in order to allow the
gateway to communicate with the Internet and VoIP network properly, using different techniques to
traverse the NAT/Firewall.
Note: The above diagram shows a 4-port SmartVoice gateway for illustration purposes.
An 8, 16 or 32 port SmartVoice gateway could also be used depending upon your
network requirements.

The table shown below lists possible solutions for different network scenarios.
LAN IP address of Internet sharing Please avoid IP address 192.168.8.1-192.168.8.254 (You may need to
change the settings of Internet sharing device or change the SmartVoice
gateway LAN Port IP address)
WAN IP of SmartVoice gateway Set as a static private IP address or DHCP; when the WAN port is set as a
static private IP, assign the LAN IP address of the Internet sharing to as default
gateway IP of SmartVoice gateway; When the WAN IP is set as DHCP, please
make sure you have DHCP server running in network to issue an IP to the
SmartVoice gateway.
NAT Traversal
There are three ways to configure
a SmartVoice gateway to traversing
NAT in Internet sharing devices. For
details, please refer to page 26.
NAT Public IP If the WAN of the IP sharing device has a static public IP
address, then the “NAT IP/Domain” address is set as the
Public IP address of the Internet sharing devices.
If the WAN of the Internet sharing device uses a dynamic
public IP address and you specify a domain name in “NAT
IP/Domain” field, which has to comply with the DDNS
settings.
Note: you also need to forward specific ports on the NAT
router to the WAN port of the SmartVoice gateway.
STUN client
Enable STUN client will avoid problems of configuring port
forwarding in the Internet sharing device, but some NAT
routers do not support STUN.
UPnP Control
point
Using UPnP to enable the SmartVoice gateway to pass
through NAT of Internet sharing device. This function only
works when the Internet sharing devices support UPnP
and has it enabled.
DDNS Settings
For details, please refer to page 27
for the DDNS Settings
The WAN of the Internet sharing device
has a static public IP address.
(Unnecessary) Disabled
The WAN of the Internet sharing device

Network Settings
The network settings are used to set the gateway’s communication ports, IP configurations, DNS and
DHCP server etc.
• Current WAN IP Address: The IP address of the WAN port.
• Listen Port UDP: It is not necessary to change the protocol of the communication port used by the
gateway, unless it conflicts with ports used by another device in your network.
• RTP Starting Port UDP: The initial value of the port number for transmitting voice data among
gateway(s). Each line requires 2 ports. For example, the 400 series gateway requires 8 UDP ports
and the 800 series gateway requires 16 UDP ports. It is not necessary to change these, unless it
conflicts with ports used by another device in your network.
For example, if the starting port is 9000, then Line 1 is using ports 9000 and 9001, and Line 2 is using
ports 9002 and 9003, and so forth.
IP Configuration (Setting WAN Port)
There are three methods of obtaining a WAN IP address:
1. Static IP
2. DHCP, means a Dynamic IP (Cable Modem)
3. PPPoE (Dialup ADSL)
Using the DHCP and PPPoE for obtaining an IP address may vary. If you are not familiar with the network
connection, please contact your local ISP.
