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.

VoIP Route Profile: Route # 3

Pick up the handset and dial 4323456789. The system will do the things as follow:

1. Change the phone number to the global number. 4323456789 is changed to 00244323456789. Then,

follow the VoIP Route Profile # 3.

2. Translate the global number to the private number followed the number translation of Server 3.

00244323456789 is translated to 0323456789.

3. If Server3 is failed, the system will use the global number, 00244323456789, to go through

Server 2.

4. Translate the global number to the private number followed the number translation of Server 2.

00244323456789 is translated to 0044323456789.

5. If Server 2 is failed, the system will use the global number to go through Server 1.

Method 3- Substitution: It helps you dial to destination that you can not dial by phone. Destination like:
[e-mail]. Fill the number into the Scan Code column and enter the desired name into the VoIP

Dial-out column.

For example,

Scan Code: 11
VoIP Dial-out: AnnyKC
User Dial Length: Disable
Route: VoIP
VoIP Route Profile: Route # 5

Pick up the handset and dial 11. The system will do the things as follow:

1. Change the phone number to the global number. 11 is changed to “AnnyKC”.

2. It sends “AnnyKC” to Server3 followed the VoIP Route Profile # 5.

4. Configuring the VoIP Telephone Adapter through
IVR

VoIP transmits voice data (packets) via the Internet, hence the condition and status of the network environment is
relatively important to the telecommunications quality. If any one of the parties involved in VoIP communications
has insufficient bandwidth or frequent packet loss, the telecommunication quality will be poor. Therefore,
excellent telecommunication can only happen when the VoIP Telephone Adapters are connected to the Internet
and when the network environment is stable.

Preparation

1. Connect the power supply, telephone set, telephone cable, and network cable properly.

2. If a static IP is provided, confirm the correct IP settings of the WAN Port (IP address, Subnet Mask,

and Default gateway). Please contact your local Internet Service Provider (ISP) if you have any
question.

3. If you are using ADSL (PPPoE) for your network connection, confirm the account number and

password.

4. If you intend to operate the VoIP Telephone Adapter under NAT, the IP range of VoIP Telephone

Adapter WAN Port and LAN Port IP Address of your Router should not be the same in order to avoid
phone failures.

Basic Setup

The VoIP Telephone Adapter provides two setup modes:

1. Telephone IVR Configuration Mode

2. Browser Configuration Mode

IVR configuration provides basic query and setup functions, while browser configuration provides full setup
functions.

4-1 IVR (Interactive Voice Response)

The VoIP Telephone Adapter provides convenient IVR functions. Users are able to get query and setup the
VoIP Telephone Adapter with a phone-set and function-codes without turning on the PC.

Note: When finishing the setup, make sure the new settings are saved. This will enable the new settings to
take effect after the system is restarted.

Instructions

FXS Port: Connect to telephones. To access IVR mode, passwords should be entered, “* * password #”.

Alphabets to digits conversion information is provided in the PPPoE Character Conversion Table. When
correct IVR passwords are entered and accepted, an indication tone can be heard indicates the system is
in IVR setup mode. Enter function codes to check or configure the VoIP Telephone Adapter.

Example: If your password is “1234”, enter

* (star) * (star) 1 2 3 4 # (pound), and now you are entering IVR

setup mode. Next, enter a function code to check or configure the VoIP Telephone Adapter. If your
password is “admin”, enter

* (star) * (star) * (star) 41 44 53 49 54 # (pound). Please refer to the IVR

DVG-2102S User’s Manual Dialing Principles

D-Link Systems, Inc. 85

5. Dialing Principles

5-1 Dialing Options

Dial the phone number which you want to call and press # to call out immediately. Note that if the “#
(pound)” not dialed, the number will be called out after 4 seconds by default. The period between number
dialed and call out is named “Inter Digits Timeout”.

If the phone number matches the setting of the Digit Map, the phone number will be dialed out through the
assigned interface automatically.

The phone number should contain at least 2 digits (not including * and #).

5-2 Number Translation

Phone number is dialed by user. The system will check if the phone number is matched Digit Map Table. If
no matched is found from Digit Map Table, it will use the phone number to look up number translation of the
server set in VoIP Routing Profile.

DVG-2102S User’s Manual Dialing Principles

D-Link Systems, Inc. 86

5-3 Routing

To achieve maximum flexibility, the number dialed will be looked up in several tables defined by the VoIP
Telephone Adapter. If no match is found from Digit Map Table, it will then look up the number from another
table and to the registered VoIP Service Provdier.

Routing Processing Flow

The routing after checking Digit Map Table may be vary. The routing accords with VoIP Route Profile. By
default, Phone Book is the first route of VoIP Route Profile. The second and third route is Server 1 and Server 2.
Server 3 is the last route. Each server has a dialing plan, i.e. number translation, table, and the number will be
translated according the dialing plan before dialing out. For default setting, the number look up flow appears
like:

Assume that the route of Default Route Profile is Server 2 as the first route, Server 3 as the second route and
Server 1 as the last route. The number look up flow appears like:
