1. Introduction
1-1 Product Overview
The DVG-5112S VoIP Gateway carries both voice and facsimile over the IP network. It u ses 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 P PPoE.
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.

IP Configuration
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, and then click the “Accept” b utton at the bottom of the scre en.
Saving the settings: Click System Operation to select “Save Settings”, “Restart”, and then click the ”Accept”
button. Wait for about 40 seconds, and the system will obtain the rquired IP value from the DHCP Server.
NOTE: After the system has obtained a new IP address, if you are using a WAN port to enter the
Web Configuration Screen, the new IP address has to be used. The same principle applies to the
next two settings.
Setting Static IP
Select “Static IP” and enter the IP address, Subnet Mask and Default Gateway values. Then click the
“Accept” button at the bottom of the screen. Save the settings, and then restart the system. Wait for about
40 seconds for the system to restart.
ADSL PPPoE Settings
Select “PPPoE” and enter the Account Number, Password and Reenter Password to confirm. Then click the
“Accept” button at the bottom of the screen. Save the settings, and then restart the system. The system will
take about 49 seconds to restart.
D-Link Systems, Inc. 14

DVG-5112S User’s Manu al
PPTP
Select “PPTP” and enter the IP Address, Subnet mask, PPTP Server, PPTP ID and Password. 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.

VLAN
Enable VLAN Tagging: this tags the packets for VLAN Router or Switch identifying.
VLAN ID: enter a uniq uely user-defined ID to each packet.
Priority: enter the proprietary.
WAN QoS
QoS (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.
ToS/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.
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.

3-6 SIP
Assuming that your registered ID and password are individual, the settings should be as above.
Number: VoIP phone number
Register: Register to prox y if selected.
Invite with ID / Account: The DVG-5112S can be invited to a VoIP trunk gateway without registeri ng
to a proxy. Please contact your VoIP service provider.
User ID/Account: VoIP account Authentication ID or account name
Password: p assword fo r VoIP account authentication
As there are various Proxy Server providers, the gateway has been desi gned to be compatibl e with as many
SIP VoIP networks as possible using RFC standards. If any kind of registration problem occurs, please
consult your VoIP service provider.
NOTE: When you register with a Proxy Server, dialing principles may vary with different Proxy Servers.
Please consult your VoIP service provider for details.
DNS SRV Settings
Use DNS SRV: The gateway asks for the related IP address of SIP Server from the records of DNS
SRV. DNS SRV uses several servers for a single domain for SIP proxy, to move services from host to
host and design some hosts as primary servers (the highest priority) for a service and others as
backups. If the primary server is not reachable, the gateway will go for backup server, and so forth…
DNS SRV Auto Prefix: This option tells the gateway to send packe t with service type when using DNS
SRV.
Proxy Fallback Interval: Set the preferred Proxy Fallback Interval. After the time expires, the gateway
gets back for registration with the primary server.

Enable Support of SIP Proxy Server / Soft Switch: Enable the functions to inter-work with Proxy
Server / Soft Switch. When SIP Proxy 1 and 2 are enabled, the system will register to SIP Pro xy 2 after
all lines have failed to register to SIP Proxy 1. SIP Proxy 2 is a backup system.
Proxy Server IP/Domain: Enter the Proxy Server IP address or URL (Uniform Resource Locator). You
can set three redundant Proxy IPs separated by semicolons.
Example: 61.123.231.1;12.34.56.78;proxy.sip.sip
Proxy Server Port: Enter the Proxy Server listen port number. (The default value is 5060)
Proxy Server Realm: This variable is used for gateway SIP account authentication in a SIP server. In
most cases, the gateway can automatically detect your SIP server realm. So you can leave this option
blank. However, if your SIP server requires you to use a specific realm you can manually enter it here.
If you fail to make a call, please contact your VoIP service provider.
TTL (Registration interval) [10-720 0 s]: Enter the desired time interval at which the gateway will
report to your Proxy Server.
SIP Domain/Use Domain to Register: Enter the correct SIP domain to avoid registration failure (it is
not necessary to set this with some Proxy Servers). If you enable “Uses Domain to Register” the VoIP
gateway will register to the proxy with the domain name you filed. Otherwise the VoIP Gateway will
register to a Proxy with the IP it resolves. If you fail to make a call, please contact your VoIP
service provider.

Outbound Proxy
All Call through OutBound Proxy:An outbound proxy serve r h andles SIP call signaling as a
standard SIP proxy server would. Further, it receives and transmits phone co nversation traffic (media)
between two communication parties. This option tells the gateway to send and receive all SIP
packets to the destined outbound proxy server rather than the remote gateway. 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 en able it.
E.164
International Call Prefix Digit: Enter the International call prefix.
Country Code: Users please select the desired country code.
Long Distance Call Prefix Digit: The long-distance prefix digit for making a long-distance call.

3-14 NAT Traversal
If your gateway is set up behind an Internet sharing device, you can select either the NAT or STUN protocol.
NAT Public IP: The IP address used by the gateway should be a private address. Furthe rmore, users
must set Virtual Server Mapping in the Internet sharing device. (For example, a virtual serve r is usu ally
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): 9000~9015 (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.
NAT 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.
Enable STUN Client: Using the STUN proto col prevents problems with setting the IP sharing function,
but some NATs do not support this protocol.
NOTE: You can use the “Status STUN 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.
STUN 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.
Enable 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 Current Status” page will show the status of UPnP.

3-15 DDNS
These settings are only necessary when the gateway is set up behind an Internet sharing device that u ses a
dynamic IP address and does not support DDNS.
Choose a DDNS Server: The current system allows users to choose either DynDNS、TZO、3322.org、PeanutHull
or a private server. You will need to apply for an account with DynDNS、TZO、3322.org、PeanutHull or a private
server before you type in the following information.

DVG-5112S User’s Manu al
Server address: the IP addre ss or URL (Uniform Resource Locator) of the DDNS Server.
Hostname: the URL of the system (or NAT) – applied from domain name registration providers (e.g.
www.dyndns.org).
Login ID and Password: The ID and password used to log-in to the DDNS server.
Behind NAT: Select this only when the system is set up behind a NAT device.
NOTE: If the gateway is set up under NAT, then enter the hostname in the NAT IP/Domain that is the
same as the Hostname of the DDNS.
Example:

3-16 FAX Settings
T.38: The T.38 protocol is used for better and faster facsimile transmission. So it is recommended to
enable this function to gain better fax quality. When this function is enabled, please select UDP or TCP.
If you select TCP and some gateways cannot use the fax function, please select UDP instead.
NOTE: When a fax tone is detected in a call, the gateway will automatically switch from voice mode to
fax mode. So fax settings will be temporarily applied to a specific port which detects fax tones, instead
of its default voice settings.
Enable High Quality : The system sends the same fax frame twice to get a high quality fax
transmission. Enabling this variable increases bandwidth requirements.
T.30: The system use s T.30 as th e protocol for fax transmi ssi on. T he param eter setting s are the same
as for voice transmission. However, enabling the T.30 protocol will consume more network resou rces
and will affect transmission quality.
NOTE: When you send fax over an IP network it needs your network to support fax over IP
functionality (either T.38 or T.30). Please consult your VoIP service provider for this setting.

3-17 Codec Settings
Preferred Co dec Type: Since different voice codecs have different compression ratios, the sound
quality and occupied bandwidths are also different. It is recommended that you use the default
provided (G.723.1) because it occupies less bandwidth and will provide better sound quality.
Jitter Buffer : Adjusts the jitter for receiving packets. If the jitter range is too wide, it will delay voice
transmission.
Silence Suppression: If one side of a connection is not speaking, the system will stop sending voice
data (packets) to decrease bandwidth usage.
Echo Canceling: Prevents poor telecommunication quality caused by echo interference.
Codec: Choose the codec that you need.
Packet Time: Defines how long the gateway send s a RTP packet or voice packet to the receiving side.
The smaller the value, the greater the bandwidth usage, but larger values increase voice delay.
Approximate Bandwidth Required: The bandwidth required varies with codec format and packet
time.

Listening Volume: Adjusts the earpiece or speaker volume.
Speaking Volume: Adjusts the microphone volume.
Tone Volume: Adds a new option to make tone volume adjustable. This setting will be applied to all
tones generated by the gateway including dial tone and busy tone.
Min. FXS Hook Flash Time: It is to set the minimum flash time for FXS detecting.
Flash Time: Used to adjust the detection period for flash signals from a phone set connected to an
FXS port. For example, if pressing the HOLD key sometimes disconnects a call, increasing the “Flash
Detect Time” should fix this issue.
Enable Polarity Reversal: As a remote site answers calls from this extension the FXS port will
reverse polarity.
FXS Chip Option 1: It is to avoid mis-detecting the loop state of a subscriber line or PBX user loop by
FXS interface. In some places, the voltage of off-hook makes it mis-detect the idle state and the active
state by FXS interface. Untick this variable if it mis-detects the state by FXS interface in your place.
Ring (Early Media) Time Limit[10 - 600secs]:The timeout to ca ncel a call when no one answers.
Enable End of Digit Tone:The gateway will play a “Beep-Beep” tone to notify that the call is in
progress.
Early Media Treatm ent: If this variable is disabled, the system will send RTP immediately after a
connection with a proxy is set up. The default setting is enabled. If communicating with other gateways
encounters problems, please disable this function.
Loop Current Drop Trigger Time: It is to set the trigger time for dropping loop current by FXS port. A
setting of zero is to disable this function. It is used to avoid the line engaged if FXS port is conn ected to
PBX.
Loop Curren t Drop Duration: It is to set the drop duration.

4. Setting the DVG-5112S through IVR
VoIP transmits voice data (packets) via the Internet. One effect of this is that telecommunications quality is closely
related to the condition and status of the network environment. If any of the parties involved in VoIP
communications has insufficient bandwidth or freque nt packet loss, the telecommunication quality will be poor.
Therefore, excellent telecommunication can only happen when the gateway is connected to the Internet and
when the network environment is stable.
Preparation
Install the gateway according to instructions. Connect the power supply, telephone set, telephone cable,
and network cable properly as described in Chapter 2.
If a static IP is used, confirm the correct IP settings of the WAN Port (IP address, Subnet Mask, and Defa ult
gateway). Please contact your local Internet Service Provider (ISP) if you have any questions.
If you are a using ADSL (PPPoE) for your network connection, co nfirm the account number and password.
If you intend to operate the gateway under a NAT, the Gateway WA N Port IP Address and LAN Port should
not use the same range in order to avoid phone failures.
Basic Setup
The gateway 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 gateway provides convenient IVR functions. Users only need to pick up a handset and enter the function
code for query and setup without using a PC.
NOTE: After 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: Connected to telephones. To access IVR mode, you should enter “* * password #”. Character to
number conversion information is provided in the PPPoE Character Conversion Table. After entering the
correct IVR password, you will hear an indication tone after which the system is in IVR setup mode. Enter
function codes to check or set the gateway configuration. (Please refer to page 43 for function codes).
Example: If your password is “1234”, enter “**1234#”
function code to check or configure the gateway. If your password is “admin”, enter “***4144534954#”
Please refer to the IVR Functions Table (page 43) for available functions and codes.
Once the first setting or query has been completed, you will hear a dial tone. Use the same procedure to
make a second query or setting. To exit IVR mode, simply hang up the phone.

Safety Instructions
Please adhere to the following safety guidelines to help ensure your own personal safety and protect your
system from potential damage. Any acts taken that are inconsistent with ordinary use of the product, including
improper testing, etc., and those not expressly approved by D-Link may result in the loss of product warranty.
Unless expressly approved by an authorized representative of D-Link in writing, you may not and may not
permit others to:
• Disassemble or reverse engineer the device or attempt to derive source code (underlying ideas,
algorithms, or structure) from the device or from any other information provided by
D-Link, except to the extent that this restriction is expressly prohibited by local law.
• Modify or alter the device.
• Remove from the device any product identification or other notices, including copyright notices and
patent markings, if any.
To reduce the risk of bodily injury, electrical shock, fire, and damage to the device and other equipment,
observe the following precautions:
Power Sources
• Observe and follow service markings.
• Do not push any objects into the openings of your device unless consistent with the authorized
operation of the device. Doing so can cause a fire or an electrical shock by shorting out interior
components.
• The powering of this device must adhere to the power specifications indicated for this product.
• Do not overload wall outlets and/or extension cords as this will increase the risk of fire or electrical
shock.
• Do not rest anything on the power cord or on the device (unless the device is made and expressly
approved as suitable for stacking).
• Position system cables and power cables carefully; route cables so that they cannot be stepped on
or tripped over. Be sure that nothing rests on any cables.
• Operate the device only from the type of external power source indicated on the electrical ratings
label.
• To help avoid damaging your device, be sure the voltage selection switch (if provided) on the power
supply is set to match the power available at your location.
• Also be sure that attached devices are electrically rated to operate with the power available in your
location.
• Use only approved power cable(s). If you have not been provided a power cable for your device or
for any AC-powered option intended for your device, purchase a power cable that is approved for
use in your country and is suitable for use with your device. The power cable must be rated for the
device and for the voltage and current marked on the device’s electrical ratings label. The voltage
and current rating of the cable should be greater than the ratings marked on the device.
• To help prevent an electrical shock, plug the device and peripheral power cables into properly
grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure proper
grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use
an extension cable, use a 3-wire cable with properly grounded plugs.
• Observe extension cable and power strip ratings. Ensure that the total ampere rating of all products
plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings
limit for the extension cable or power strip.
• To help protect your device from sudden, transient increases and decreases in electrical power, use
a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
• Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local/national wirin g rules.
Page 56
• When connecting or disconnecting power to hot-pluggable power supplies, if offered with your
device, observe the following guidelines:
• Install the power supply before connecting the power cable to the power supply.
• Unplug the power cable before removing the power supply.
• If the system has multiple sources of power, disconnect power from the device
by unplugging all power cables from the power supplies.
Servicing/Disassembling
• Do not service any product except as expressly set forth in your system documentation.
• Opening or removing covers that are marked with the triangular symbol with a lightning bolt may
expose you to an electrical shock. Only a trained service technician should service components
inside these compartments.
• To reduce the risk of electrical shock, never disassemble this device. None of its internal parts are
user-replaceable; therefore, there is no reason to access the interior.
• Do not spill food or liquids on your system components, and never operate the device in a wet
environment. If the device gets wet, see the appropriate section in your troubleshooting guide or
contact your trained service provider.
• Use the device only with approved equipment.
• Move products with care; ensure that all casters and/or stabilizers are firmly connected to the
system. Avoid sudden stops and uneven surfaces.
Environment
• Do not use this device near water (e.g. near a bathtub, sink, laundry tub, fish tank, in a wet
basement or near a swimming pool).
• Do not use this device in areas with high humidity.
• This device must not be subjected to water or condensation.
• Keep your device away from radiators and heat sources. Also, do not block cooling vents.
Cleaning
• Always unplug the power before cleaning this device.
• Do not use liquid or aerosol cleaners of any kind. Use only compressed air that is recommended for
electronic devices.
• Use a dry cloth for cleaning.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static damage, discharge
static electricity from your body before you touch any of the electronic components, such as the
microprocessor. You can do so by periodically touching an unpainted metal surface on the chassis.
You can also take the following steps to help prevent damage from electrostatic discharge (ESD):
1. When unpacking a static-sensitive component from its shipping carton, do not remove the
component from the antistatic packing material until you are ready to install the
component in your system. Just before unwrapping the antistatic packaging, be sure to
discharge static electricity from your body.
2. When transporting a sensitive component, first place it in an antistatic container or
packaging.
3. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads,
workbench pads, and an antistatic grounding strap.
