DVG-7022S/7044S/7062 User’s Manual Produect Overview
1. Introduction
1-1 Product Overview
The DVG-7022S/7044S/7062S VoIP Gateway carries both voice and facsimile over the IP network. It uses the
industry standard SIP call control protocol so as to be compatible with free registration services or VoIP service
providers’ systems. As a standard user agent, it is compatible with all common Soft Switches and SIP proxy
servers. While running optional server software, the gateway can be configured to establish a private VoIP
network over the Internet without a third-party SIP Proxy Server.
The gateway can be seamlessly integrated into an existing network by connecting to a phone set and fax
machine. With only a broadband connection such as an ADSL bridge/router, a Cable Modem or a leased-line
router, the gateway allows you to use voice and fax services over IP in order to reduce the cost of all long distance
calls.
DDNS support makes the gateway reachable via its domain name where an ISP dynamically assigns an IP
address. By enabling the CDR function, administrators are allowed to log-in and view all call records, for example
call duration, time and date of calls, and latency.
The gateway can be assigned a fixed IP address or it can have one dynamically assigned by DHCP over PPPoE.
It adopts either the G.711, G.726, G.729A or G.723.1 voice compression format to save network bandwidth while
providing real-time, toll quality voice transmission and reception.

3-1 Network Settings (WAN)
The network settings are used to set the gateway’s communication ports, IP configurations, and Phone
Book Manager IP settings.
yCurrent WAN IP Address: The IP address of the WAN port.
yListen 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.
yRTP Starting Port UDP: The initial value of the port number for transmitting voice data among
gateway(s). Each line requires 2 ports. For the DVG-7022S/7044S/7062 gateway 8/16 UDP ports are
required. It is not necessary to change the setting, unless it conflicts with ports used by another
network device.
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 five methods of obtaining a WAN port IP address:
1. Static IP
2. DHCP, which means a Dynamic IP (Cable Modem)
3. PPPoE (dial-up ADSL)
4. PPTP
5. BigPond (for Australia only)
Methods for using DHCP and PPPoE for obtaining an IP address may vary. If you are not familiar with
creating a network connection, please contact your local ISP.
Setting Dynamic IP (DHCP)
Click “DHCP” to obtain a Dynamic IP address, enter the “Hostname” and “Vendor Class ID” if required by
your local ISP and then click the “Accept” button at the bottom of the screen.

BigPond (for Australia only)
Click “BigPond Cable” and enter the User Name and Password. Then click the “Accept” button at the
bottom of the screen.
(DNS) Settings
Domain Name Server (DNS): While a gateway is accessing another gateway or a computer with a
hostname, it will look up the IP address from the DNS provided by your ISP. Normally, the ISP assigns DNS
information while negotiating with PPPoE or DHCP. If the DNS is not assigned automatically or the WAN
port is assigned a static IP address, the DNS settings must be assigned manually.
Auto: the gateway learns primary and secondary addresses from the ISP’s DHCP server or PPPoE server.
Manual: enter the primary and secondary addresses manually. Please be sure that the IP addresses are
correct otherwise the gateway will not be able to access hosts using hostnames instead of IPs.
WAN Link Speed
It is used to choose the WAN Ethernet link speed. The default is Auto. Please choose the same speed with
Router/Switch/Hub, if VoIP gateway connected to Router/Switch/Hub has the link problem.
Clone MAC
Some Internet Service Providers (ISPs) assign bandwidth via MAC (Media Access Control) addresses. You
can click the "Clone" button to type in a MAC address which will be recognized by your ISP. It is only
necessary to fill in the field if it is required by your ISP.
The “Your MAC Address” field will be blank as you log-in via the WAN port.

3-3 QoS Settings
WAN QoS
yQoS (Quality of Service): Sets true bandwidth of your Internet connection to ensure sound quality
during transmission. (When this function is enabled, voice packets have the highest priority to ensure
telecommunication quality while less bandwidth is assigned for data transmission.) Some models of
the VoIP gateway without this function will adjust bandwidth automatically.
yToS/DiffServ (Type of Service/DSCP): Voice packets have the highest priority to ensure
telecommunication quality; the larger the value you set, the higher the priority.
NOTE: Please contact your ISP when you configure these values.
LAN QoS
yPriority: The gateway can prioritize LAN ports. Data from HIGH priority port are delivered prior to
those from LOW priority port while they arrive at the same time.
yFlow Control: Enable or Disable Flow control.
yIncoming Rate Limit: Set the incoming (from WAN to LAN) rate limit of a specific LAN port (can not
exceed the real downstream bandwidth).
yOutgoing Rate Limit: Set the outgoing (from LAN to WAN) rate limit of a specific LAN port (can not
exceed the real upstream bandwidth).

DVG-7022S/7044S/7062 User’s Manual Caller ID
3-4 NAT/DDNS
NAT Traversal
If your gateway is set up behind an Internet sharing device, you can select either the NAT or STUN protocol.
yNAT Public IP: The IP address used by the gateway should be a private address. Furthermore, users
must set Virtual Server Mapping in the Internet sharing device. (For example, a virtual server is usually
defined as a Service Port, and all requests to this port will be redirected to this specified server’s
private IP address).
The default ports of the gateway are listed below:
Listen Port (UDP): 5060
RTP Starting Port (UDP): Listen Port used for telephone communication.
Port of Web Access from WAN (TCP): the number you set in this option on the Network Settings page.
DVG-7022S: 9000~9023
DVG-7044S: 9000~9047
DVG-7062S: 9000~9047
oNAT IP/Domain: Enter the NAT Server IP address (real public IP address of the Internet sharing
device); or enter a true URL (Uniform Resource Locator) when DDNS is used. Please refer to the
DDNS settings.
NOTE: If you are setting a public IP in this field, it has to be a static public IP, otherwise VoIP
communication may not be established properly. Please contact your ISP to check whether your Internet
connection has static public IP addresses.
yEnable STUN Client: Using the STUN protocol prevents problems with setting the IP sharing function,
but some NATs do not support this protocol.
NOTE: You can use the “Status ÆSTUN Inquiry” page to detect the NAT type of your Internet sharing
device. If the NAT type is “Symmetric NAT,” then the gateway is not able to traverse the NAT. It is not a flaw
of the gateway design, but rather a limitation of the STUN protocol.
ySTUN Server IP/Domain and Port: Enter the STUN server IP address and Listen Port number. You
can set two STUN server IPs separated by a semicolon.
yEnable UPnP Control Point: This variable will enable the gateway’s IP traffic to pass through an
Internet sharing device. This function only works when the Internet sharing device supports UPnP and
has it enabled.
NOTE: The “Status ÆCurrent Status” page will show the status of UPnP.
