DVG-2102S User’s Manual Product Overview
D-Link Systems, Inc. 4
1. Introduction
1-1 Product Overview
The DVG-2102S is designed to carry 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 VoIP Telephone Adapter can be configured to establish a private VoIP network over
the Internet without a third-party SIP Proxy Server.
The DVG-2102S 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 VoIP Telephone Adapter allows you to use voice and fax services over IP in order to reduce the cost of
all long distance calls.
The DVG-2102S can be configured a fixed IP address or it can have one dynamically assigned by DHCP or
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 SETUP
3-1-1 Internet Setup
WAN (Wide Area Network) Settings are used to connect to your ISP (Internet Service Provider). The WAN
settings are provided to you by your ISP and oftentimes referred to as "public settings". Please select the
appropriate option for your specific ISP.
IP Configuration (Setting WAN Port)
There are five methods of obtaining a WAN port IP address:
1. DHCP, which means a Dynamic IP (Cable Modem)
2. Static IP
3. PPPoE (dial-up ADSL)
4. PPTP
5. L2TP
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.
After selecting the suitable option, click Accept at the bottom of the screen to save the settings.
You need to save the changes and restart the VoIP Telephone Adapter to make the changes active. Saving
the settings: Click MAINTENANCE and select Save/Restart in System from the left menu. Tick Save
Settings and Restart, then click Accept. Wait for about 40 seconds before the VoIP Telephone Adapter
obtaining an IP address by the method you selected.
Note: When the system has obtained a new IP address, and you are using a WAN port to enter the Web
Configuration Screen, the new IP address has to be used before you can get connected to the VoIP
Telephone Adapter. The same principle applies to the next two settings.

Outbound Proxy Support: Check the box to send all SIP packets to the destined outbound proxy server.
An outbound proxy server handles SIP call signaling as a standard SIP proxy server would do. Further, it
receives and transmits phone conversation traffic (media) between two communication parties. This option
tells the VoIP Telephone Adapter to send and receive all SIP packets to the destined outbound proxy
server rather than the remote VoIP device. This helps VoIP calls to pass through any NAT protected
network without additional settings or techniques. Please make sure your VoIP Service Provider supports
outbound proxy services before you enable it.
Outbound Proxy IP/Domain: Enter the outbound proxy’s IP address or URL.
Outbound Proxy Port: Enter the outbound proxy’s listening port.
