DVG-3016S/3032S User’s Manual Product Overview
D-Link Systems, Inc. 1
1. Introduction
1-1 Product Overview
The DVG-3016S/3032S 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.729Aor G.723.1 voice compression format to save network bandwidth while
providing real-time, toll quality voice transmission and reception.

3. Gateway Configuration – Use Web Browser
The VoIP gateway allows users to configure its settings using a web interface (Web UI). You can access the
Configuration Menu by opening a web-browser (e.g., Internet Explorer or Netscape Navigator) and entering the
factory default LAN IP address: 192.168.8.254. The IP address of the Web UI is same as the default LAN IP
noted elsewhere in this user’s manual.
You can also use an ordinary telephone, connect it to the gateway, and dial ”101” to inquire about the current
WAN Port IP address and then use the WAN port to log-in.
Instructions
yOpen a Web-Browser (e.g., Explorer, Navigator, Opera, Firefox).
yEnter the LAN port IP address. The default LAN port IP address is: 192.168.8.254.
yThe log-in screen below will appear after you connect. (The factory default settings for Login ID and
Password are blank (i.e., no login ID, no password).)
The gateway does not allow multiple people to configure the gateway simultaneously. Please remember to
logout or restart the system if you are not using the web configuration function.

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. 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)

(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 when the 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.

Using Phone Book Manager
yEnable Phone Book Manager Server: this allows other gateway users to register the IP address and
telephone number in this Phone Book manager. It is recommended that the unit appointed as the
Phone Book Manager use static IP.
yShare Phone Book to Clients: While this option is enabled and the gateway is performing as a Phone
Book Manager, this gateway will append its Phone Book entries to the Manager for other clients to
lookup.
yTTL (Time to Live): If a gateway system that is controlled by the Phone Book Manager does not
report back within the deadline set by TTL, the system will be excluded from the user’s list. Each
gateway should report to the Phone Book Manager once every 30 seconds.
yRegister to Phone Book Manager: To register to the Phone Book Manager.
yVoIP failure announcement: As soon as the registration to Phone Book Manager is failed, the
gateway will drive IVR system to play out failure announcements for the caller

telecommunication quality; the larger the value you set, the higher the priority.
NOTE: Please contact your ISP when you configure these values.
*VLAN – This feature is only supported for the special hardware.
VLAN is optional. It works with the Router or Switch that supports VLAN. There are 2 VLAN groups: Voice
and data (LAN). This improves efficiency of network performance and security.
Enable VLAN Tagging: It is to tag the packets for VLAN Router or Switch identifying.
VLAN ID: It is to assign uniquely a user-defined ID to each packet.
Priority: It is the proprietary to VLAN Router or Switch.
Note: Please do not change anything here unless requested by your ISP.

DVG-3016S/3032S User’s Manual NAT/DDNS
D-Link Systems, Inc. 13
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.
DVG-3016: 9000~9095
DVG-3032: 9000~9191
yNAT 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: 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.

D-Link Systems, Inc. 16
3-5 Caller ID
yFXO Caller ID Detection: Used to detect the Caller ID delivered from the PSTN to the FXO port.
When enabled, the Caller ID detected on the FXO port will be sent to the SIP Proxy Server on
transit in (dialing out) calls.
yDetection Level: If FXO can’t detect Caller ID, try to adjust it until it can.
NOTE: If you register the gateway to a Proxy, you may be unable to make a call because the
gateway will not send the number for authorization.
yFSK Caller ID Type: Bellcore is used inAustralia caller ID standards.
yAnonymous Caller ID (CLIR): When enabled, anyone receiving a call from you will not display
your number if they have caller ID.
NOTE: If you register the gateway to a Proxy and you check this option, you may be unable to make a
call. This is due to the fact that the VoIP gateway doesn’t send the number for authorization.
yCLIR At Transit In W/O Caller ID: When not enabled, if the FXO can detect caller ID in a call
from PSTN, the gateway will use the detected caller ID as caller identification when it makes
transit in calls; if FXO cannot detect caller ID in a call from PSTN, the gateway will use
“anonymous” as caller identification for transit in calls. When it enabled, the gateway will always
uses “anonymous” as caller identification for transit in calls.
