1. Introduction
Product Overview
The stand-alone VoIP Gateway carries both voice and facsimile over the IP network. It supports
SIP industry standard call control protocol to be compatible with free registration services or VoIP
service providers’ systems. It works in two different modes: UA (User Agent) or Server. As a
standard user agent, it is compatible to all well-known Soft Switches and SIP proxy servers.
While running the optional server software, the gateway can be configured to establish a private
VoIP network over the Internet without a 3rd party SIP Proxy Server.
The gateway can be seamlessly integrated to existing network by connecting to a phone set,
PBX, key telephone system, fax machine or PSTN line. With only a broadband connection such
as ADSL bridge/router, Cable Modem or leased line router, it allows you to gain access to voice
and fax services over IP in order to reduce the cost of international and long distance calls.
With the support of DDNS, it makes the gateway reachable by its domain name where the ISP
dynamically assigns the IP address. It helps users to host a web site or mail server in a PPPoE
or DHCP network. By enabling the CDR function & setting up a simple server, administrators are
allowed to log and view all call records such as call duration, time and date of calls and latency,
etc.
The gateway can be assigned with fixed IP address or by DHCP, PPPoE. It adopts the G.711,
G.726, G.729A or G.723.1 voice compression format to save the network bandwidth while
providing real-time and toll quality voice.

Hardware Description
Front Panel
Power Indicator: Green light indicates a normal power supply.
Run Indicator: Blinking green light indicates normal operation.
Alarm Indicator: When the system starts up, the red light will blink. It also indicates the
gateway’s abnormal operation.
P1 – P16 stands for Port 1 – Port 16: Connect to your analog telephone.
WAN stands for the WAN Port Indicator.
LAN stands for the LAN Port Indicator.
When starting up the system, the Alarm, Run, and Power indicators will light up.
After about 40 seconds, the Alarm indicator will go off, the Run indicator will blink
in green, and the Power indicator will stay green under normal operational
conditions. If the Alarm indicator continues to blink, it means the system is
currently communicating with ISP and has yet to obtain an IP address.
When the WAN is connected, the WAN indicator will light up in green and if data is
being transmitted over the Internet, the indicator blinks in green and orange.
Rear Panel
NOTE: Do not connect Phone ports to each other. Also, do not connect any Phone ports
directly to a PSTN line or internal PBX. If any of these are done, your DVG-2016S may be
damaged.
Restore to factory default: (IP address, User’s. Name and Password)
(1) Pull off the power plug.
(2) Press reset (do not let go of the reset button).
(3) Plug the plug back into the socket (do not let go of the reset button).
(4) Let go of the reset button after 6 seconds. Factory settings will be restored.
2. Installation and Applications
Network Interface
The network interface is divided into 3 basic modes as described below:
Gateway can be assigned with a Public IP Address
Gateway can be built under the existing NAT
Gateway Assigned with a Public IP Address
The gateway will have a Public IP address for Internet connection regardless of whether it is a static
IP address, DHCP (using a Cable Modem), or PPPoE (Dialup / ADSL).
Gateway IP Settings
Need to set up as static IP,
DHCP, or PPPoE
NAT/STUN Settings
Unnecessary (Disabled)
DDNS Settings
Unnecessary (Disabled)
5
Gateway in a NAT network
The gateway uses a virtual IP address and the IP sharing function of other systems to connect to
the Internet.
LAN IP address of IP sharing
Please avoid IP address 192.168.0.1-192.168.8.254 (You may need
to change the settings of IP sharing or change SIP series Gateway
LAN Port IP address)
Gateway IP Settings
Set as static IP address, and assign the LAN IP address of the IP
sharing to the Default Gateway.
NAT /STUN Settings
Enable
If the WAN of the IP sharing device has static IP address,
then the NAT IP address is set as the Public IP address of
the IP sharing.
If the WAN of the IP sharing device uses a dynamic IP
address, then it has to comply with the DDNS settings.
When suing NAT, you must enter the URL (Uniform
Resource Locator) that is registered to the DDNS server.
DDNS Settings
The WAN of the IP
sharing device has a
static IP address.
Disabled
The WAN of the IP
sharing device has a
dynamic IP address.
Enabled: enter the registered URL (Uniform
Resource Locator) into the network settings
-> under NAT
Telephone Interface Description
Example for DVG2016S:
DVG2016S connecting directly to phone sets
After connecting telephone sets to P1-P16, users can make direct calls, (P1-P16 are FXS
interfaces). Each set acts as an independent extension line.
Integrating the DVG2016S with PBX
P1-P16 is FXS interfaces, and some of them can be connected to telephone sets for direct calls.
Others can be connected to the PBX so other extension lines can make VoIP calls.

3. Setting the Gateway through IVR
VoIP transmits voice data (packet) via the Internet to achieve telecommunications. This means that
the telecommunication quality is closely related to the whole network environment. If any one of the
telecommunicating parties has insufficient bandwidth or frequent packet loss, the
telecommunication quality will be poor. Therefore, an excellent telecommunication can only be
created when Gateway is connected to the Internet and when 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 desired 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 questions.
If using dialup ADSL (PPPoE) for network connection, confirm the dialup account number
and password.
If users wish to build Gateway under the NAT, Gateway WAN Port IP address and LAN Port
should not use the same range. This is to avoid phone failures.
Basic Settings of a Gateway
IP Settings— Connecting Gateway to the Internet.
Gateway provides two setting modes:
1. Telephone IVR Setting Mode
2. Browser Setting Mode
The IVR provides basic query and setting functions, while the browser provides a full setting
function.
IVR (Interactive Voice Response)
Gateway provides convenient IVR functions. Users only need to pick up a handset and enter the
function code for the query and setting without using a PC.
NOTE: After finishing the settings, make sure the new settings are saved. This is so that the
new settings will take effect after the system is restarted.
Instructions
FXS Port: Connected to telephones. To enter IVR mode, enter “ * * password #” after
hearing the dial tone. When you hear a second dial tone, the system is in IVR mode,
enter the function code. (Please refer to the Advanced Settings on page 35 for these codes)
Example: The factory default code is blank. Enter “**#”. You are now in IVR setting mode, enter the
desired code. E.g.: if the code is 1234, then enter “**1234#”. Or If your password is abc123 then
you access IVR by pressing ***414243010203#
Once the first setting or query has been completed, you will hear a dial tone. Then use the
same procedure to make a second query or setting. To exit IVR mode, simply hang up the
phone.
Example: enter “**#” (You are now in IVR mode) enter 101 (to query IP address)
the system
responds with an IP address you can continue with more settings or queries: enter 111 (to set IP
address) enter 192*168*1*2 (IP number).
Save Settings
After entering IVR mode, dial 509 (Save Settings). Wait for about 3 seconds and after hearing a
confirmation tone “1”, hang up the phone. Please reboot the Gateway to enable the new settings.
To inquire about current Gateway’s WAN Port IP address
After entering IVR mode, dial 101. The system will repeat the current WAN Port IP address.
If the system does not repeat the IP address, it indicates that the Gateway is not currently
connected to the Internet. Please check if the cable connection, account number, and password are
correct.

1. Setting a Gateway with WEB Browser
The gateway allows users to make settings using a web browser. After opening a browser, enter
Gateway’s IP address as the website address in order to enter the Web configuration screen as shown in
the following diagram.
You can also enter ”101” from the handset to inquire about the current WAN Port IP address. The factory
default LAN Port IP address is 192.168.8.254.
Instructions
Open an Internet browser.
Enter gateway’s WAN Port IP address in the website address area (If the PC is connected to the
LAN Port, enter the LAN Port IP address. The default is 192.168.8.254)
The following registration screen will appear (The factory default settings for Login ID and
Password are left blank).
Change the default settings of Administrator’s Name, Password and Web UI Login ID, Password in
Advanced Options.
After completing and confirming the settings, some of the settings will take effect immediately. But
network related settings would take effect after the gateway is restarted. Please go to System
Operation to save the settings before restarting the system.
The gateway doesn’t allow multiple people to configure the gateway at same time. If a user logs into
the system, other users from different IP addresses cannot login at the same time. Please
remember to logout or restart the system if not using the web configuration function.
Network Settings (WAN)
The network settings are used to set the gateway’s communication ports, IP configurations, and Phone
Books Manager IP etc.
15
Listen Port UDP: It is not necessary to change the protocol of the communication port used
by the gateway.
RTP Starting Port UDP: The initial value of port number for transmitting voice data among
Gateway(s). Each line requires 2 ports (RTP/RTCP). It is not necessary to change these.
For example: If the starting port is 9000, then Line 1 is using 9000(RTP) and 9001(RTCP),
and Line 2 is using 9002 and 9003, and so forth.
IP Configuration (Setting WAN Port)
There are four methods of obtaining a WAN port IP address:
1. Static IP
2. DHCP, means a Dynamic IP (Cable Modem)
3. PPPoE (Dialup ADSL)
4. PPTP.
Using the DHCP and PPPoE for obtaining an IP address may vary. If not familiar with the network
connection, please contact your local ISP.
Setting Dynamic IP (DHCP)
Click “DHCP” to obtain a Dynamic IP address, then click the “Accept” button at the bottom of the screen.
Save the settings: Click System Operation to select “Save Settings”,
”Restart”, and then click the ”Accept” button. Wait for a while (about 40 seconds), and the system will
obtain the related IP value from the DHCP Server.
NOTE: After the system has obtained a new IP address, if using WAN Port to enter the Web Configuration
Screen, a new IP address has to be used. The same applies to the following 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” Enter the Account Number, Password and Reenter Password to confirm. Then click the
“Accept” button at the bottom.
Save the settings, and then restart the system. The system will take about 49 seconds to restart.
PPTP※
17
Select “PPTP” and enter the IP Address, Subnet mask, PPTP Server, PPTP ID and Password. Then click
the “Accept” button at the bottom.
BigPond (for Australia use only)
Click “BigPond Cable” Enter User Name and Password. Login Server is optional. Then click the “Accept”
button at the bottom.
(DNS) Settings
Domain Name Server (DNS): While a gateway is accessing another gateway or computer with a hostname,
it will look up the IP address from the DNS provided by ISP. The ISP whilst negotiating with PPPoE or
DHCP usually assigns the DNS information. In the case that the DNS is not assigned automatically or
WAN port is assigned with a static IP address, the DNS information must be assigned manually.
Auto : Gateway learns primary & secondary addresses from ISP’s DHCP server or PPPoE server.
Manual
: Enter the primary & secondary addresses manually. Please be sure the IP addresses are
correct otherwise the gateway will not be able to access hosts with its hostname.
Clone MAC
Some Internet Service Providers (ISP) assigns the bandwidth via the MAC (Media Access Control)
Address. You can click the " Clone" button to copy the MAC address of the Ethernet Card installed in the
computer used to configure the device. It is only necessary to fill in the field if required by your ISP.
The “Your MAC Address” will be blank as you log in through WAN port.
Using Phone Books Manager
Enable Phone Books Manager Server: It allows other Gateway users to register the IP
address and telephone number in this Phone books manager. It is recommended that the
unit appointed as the Phone Book Manager use static IP.
Share Phone Book to Clients: While this option is enabled and the gateway is performing as
a Phone Books Manager, this gateway will append its Phone Book entries to the Manager
for other clients to lookup.
TTL (Time to Live): If a Gateway system that is controlled by the Phone Books 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 Books Manager once every 30
seconds.
Register to Phone Books Manager: To register to the Phone Books Manager.
Gateway Name for Phone Book Manager: The alias registered with the Phone Books
Manager.
Phone Books Manager Login Password: Enter the registered password. If this system is
serving as the Phone Books Manager, the set password is also the password used for
registering other Gateway systems.
Phone Books Manager IP/Domain: Enter the IP address for the Phone Books Manager. It
supports URL (Uniform Resource Locator).
Phone Books Manager Server Listen Port: The protocol communication port for transmitting
signals between the Phone Books Manager and other Gateway systems. Please confirm
whether the setting is the same as that of the Phone Books Manager.
19
Network Settings (LAN)
LAN interface mode※
Router: The system serves as a router with NAT.
Bridge: The system serves as a bridge between WAN port and LAN port without NAT. (LAN
default gateway will still be accessible for configuration).
LAN IP/Subnet mask
Gateway LAN Port IP address and the subnet mask value.
Port of Web Access from WAN: Http port for WAN. To make this setting, the LAN Port must
be used. WAN Port cannot make this setting. Always use port 80 when connecting to
LAN port. 0 is to disable http port for WAN.
Enable Web UI: It disables any access from WAN and LAN if ticked.
Enable Telnet Service: It allows user to make settings from Telnet.
QoS Settings
WAN QoS
QoS (Quality of Service): Sets an external bandwidth to ensure sound quality during
transmission (When this function is enabled, the voice packet has the highest priority to
ensure telecommunication quality while less bandwidth is assigned for data transmission).
Some models of the gateway without this function can adjust the bandwidth automatically.
ToS/DiffServ (Type of Service/DSCP): The voice packet has the highest priority to ensure
telecommunication quality; the larger the value you set, the higher priority you will get.
21
NAT/DDNS
NAT Traversal
If a Gateway is set up under an IP sharing setting, you can select either the NAT or STUN
protocol.
NAT Public IP: The IP address used by the gateway should be a virtual address. Further
more, users must set the Virtual Server Mapping in the NAT Server (A virtual server is
defined as a Service Port, and all requests to this port will be redirected to this specified the
server IP address).
The default port is listed below:
Listen Port (UDP): 5060
RTP Starting Port (UDP): 9000~9031 (Listen Port used for telephone communication).
Http Port (TCP): 80
NAT IP/Domain: Enter the NAT Server IP address (Real External IP address of NAT Server)
then fill in the URL (Uniform Resource Locator). If using DDNS, please refer to the next
setting item

All Call through OutBound Proxy:An outbound proxy server handles SIP call signaling as a
standard SIP proxy server would. Furthermore, it receives and transmits phone
conversation traffic (media) in between two talking gateways. 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 enable it.
Session Expiration: It is to avoid the billing of abnormal dropping the call because of
Internet. The default is disabled.

connected to the FXS port. For example, if pressing the HOLD key will disconnect a call,
increase the “Flash Detect Time” should fix this issue.
Enable Polarity Reversal: As the remote site answer this call or hook on the FXS port will
reverse the polarity.
Codec
Preferred Codec Type: Since different voice codec have different compression ratios, so
33
the sound quality and occupied bandwidths are also different. It is recommended to use the
default provided (G.723.1) because it occupies less bandwidth and will provide better sound
quality.
Jitter Buffer: Adjusts the jitter to receive a packet. 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 (package) to decrease bandwidth usage.
Echo Canceling: Prevents poor telecommunication quality caused by echo interference.
Codec: Choose the codec that you needs.
Packet Time: Defines how long the gateway sends a RTP packet-voice packet- to the other
side. The smaller the value, the more bandwidth usage. The larger the value, the more
voice delay.
Approximate Bandwidth Require: The bandwidth required varies with Codec format and
packet time.
Fax Settings
T.38: The T.38 protocol is used for better and faster facsimile transmission. When this
function is enabled, the following fax and voice parameter settings will be disabled, so it is
recommended to enable this function to gain better fax quality. When this function is
enabled, please select UDP, TCP, or AUTO. If selecting TCP and some routers cannot use
the Fax function, please select UDP instead.
Enable High Quality: The system sends the same FAX frame twice to get a high quality of
the FAX. It requires more bandwidth.
Enable Secure T.38: This allows gateways to send faxes on both sides.
T.30: The system uses T.30 as the protocol for fax transmission. The parameter settings
are the same as for voice transmission. However, enabling the fax function will consume
more network resources and will affect transmission quality.
FAX Detect sensitivity:Used to adjust the sensitivity of detection as to whether a phone call
is a FAX or not.
This is used as a standard to determine whether or not to hang up the phone. The system will
hang up the phone automatically to avoid keeping the line engaged if the detected volume is
below the Silence Detection Threshold and the time exceeds the Drop Silent Call Timeout.
Silence Detection Threshold: Set the volume as a standard.
Drop Silent Call Timeout: Set the time to hang up the phone.

described below:
Current Intranet only supports static IP mode, and the settings at the PC end are as follow:
Available IP address Range : 192.168.8.1 – 192.168.8.253 (default address of Gateway is
192.168.8.254)
Subnet Mask
: 255.255.255.0
Default Gateway
: 192.168.8.254
The above values vary with different LAN Port Settings.
Assume Gateway’s LAN settings are,
IP address : 192.168.3.1
Subnet Mask
: 255.255.255.0
Then, the settings at PC end should be as follows:
Valid IP address range : 192.168.3.2 – 192.168.3.254
Subnet Mask
: 255.255.255.0
Default Gateway

button and after completing the settings, users can use both the VoIP and network services
concurrently.
3. Coding Principle
Instruction
After a phone number is entered, dial # to call out immediately or, wait until the “Inter DTMF
Timeout” expires (defined in “Advanced Options”, default=4 seconds).
If the phone number fits the setting of Digit Map, the gateway dials out the phone number
through the assigned interface automatically.
The phone number should have at least 2 digits (not including * and #).
Dialed Number Processing Flow
To maintain maximum flexibility, the number dialed will be looked up from several tables defined in
the gateway. Once no match can be found, it will look up again from the registered SIP Proxy Server.
The look up flow is shown below:
