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 3 rd

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

Rear 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.

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

NAT /STUN Settings

Set as static IP address, and assign the LAN IP address of the IP sharing to the Default Gateway.

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.

DDNS Settings

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.

Disabled The WAN of the IP sharing device has a static IP address.

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:

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

Enable STUN Client: Using STUN protocol prevents problems with setting the IP sharing function, but some NAT do not support this protocol.

STUN Server IP/Domain and Port: Enter the STUN server IP address and Listen Port number. You can set 2 STUN server spread by semicolon.

Enable UPnP Control Point: To enable the gateway’s IP traffic to pass through a NAT server. This function only works when the NAT server supports UPnP and has it enabled.

DDNS

These settings are only necessary when the gateway is set up under a NAT that uses a dynamic IP address and do not support DDNS.

23

Choose a DDNS Server: The current system allows users to choose either DynDNS、TZO、3322.org、

PeanutHull or a private server. Please apply for a user account before choosing a service provider.

Server address: Sets up the IP address or URL (Uniform Resource Locator) of the DDNS

Server.

Hostname: The URL of the system (or NAT) – apply from a domain name registration providers.

Login ID and Password: The ID and password are used to log into the DDNS server.

Anonymous Caller ID (CLIR): When enabled, the caller’s phone set will not display your number.

Note: If you register the gateway to a Proxy, you may be unable to make a call. This is due to the fact that the gateway doesn’t send the number for authorization.

Enable: Enable a line; if some lines are not used, disable them (Pause Function) to avoid unnecessary waiting when an incoming call is diverting to this line.

Hotline Functions

FXS port: When the user picks up the phone, the gateway automatically dials your assigned hotline number. When in hotline mode, other lines cannot be used.

Hot Line No.: Enter the hot line number for an automatic dialing function.

Warm Line: When the warm line function is in use, user can dial a number. Otherwise the system will divert incoming calls from an outside line to the Hot Line Number after a set wait time.

FXS Group: Select group hunting when there is an incoming call, the gateway will automatically assign an unassigned call according to Hunting Priority. If Line 2 does not want to be set as an assigned line to receive any inbound calls, the function can be disabled.

Users can also use the Up or Down key to adjust hunting priority.

Enable FAX: Enable this line to detect if there is a FAX tone to transfer the Codec.

Hunting/Ring: It is able to set FXS group hunting using simultaneous ring or sequential ring.

Sequential Ring Time: To set the ring time of each port, when sequential ring is chosen.

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.

Session Refresh Request: to send the packet of UPDATE or re-INVITE to

Session Refresher: It is the gateway’s role in Session Timer. UAS is an originator, and UAC is a replier.

Enable P-Assert: It is for caller id protect.

Privacy Type: Privacy requested for Third-Party Asserted.

Calling Features

Do Not Disturb: It will only be able to call out when it is enabled.

Unconditional Forward: All incoming calls will be forwarded to the “Forwarding Number” automatically. If it forwards to FXO, it only make FXO hook off, not make FXO dial out.

Busy Forward: Forward the incoming call to “Forwarding Number” when the port is busy.

No Answer Forward: Forward the incoming call to “Forwarding Number” after ring timeout expires without answer.

Call Hold: Enable the call hold feature on the specific FXS port.

NOTE: Call Hold must be checked; Call Transfer or Call Waiting is active.

Call Transfer: Enable the call transfer feature on the specific FXS port.

Call Waiting: Enable the call waiting feature on the specific FXS port.

Three-Way Calling / Service ID: Feature code of conference call defined on Nortel Soft Switch.

Calling Feature Instructions:

Call Hold: Ongoing call will be put on hold after FLASH button pressed on the phone set. The gateway will play a repeating music to the remote end.

Call Transfer: Ongoing call will be put on hold after FLASH button pressed on local phone set

(gateway plays a repeating music to the remote end). Meanwhile, local user can dial out to another number after dial tone observed. After the handset is back on the hook, the call on hold will then be transferred to the new call regardless of the status of the new call. If wrong number is dialed for the new call, just press the FLASH button to get back the call on hold. In another case, if the local user doesn’t hang up the phone after new call sets up, press FLASH button to switch between the first call and the new call. Please be informed that PBX between phone sets and the gateway must support FLASH features to make this function work correctly. If a phone set is connecting directly to the FXS port of the gateway and not functioning to FLASH, please adjust the settings in “Flash Detect Time” in category “Advanced Options”.

Example of a Three-Way calling:

1. Alex dials to Bob, Bob answers that call.

2. Alex presses Flash and call to Coral (Bob is on hold), Coral answers that call.

3. Alex dials *61 then presses Flash, thus conference call is created.

Or

4. Alex dials to Bob, Bob answers that call.

5. Coral dials to Alex (Call Waiting), Alex presses Flash to pick the second call and talk to

Coral.

6. Alex dials *61 then presses Flash, thus conference call is created.

Enable Polarity Reversal: As the remote site answer this call or hook on the FXS port will reverse the polarity.

Preferred Codec Type: Since different voice codec have different compression ratios, so

33

Fax Settings

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.

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.

2. IP Sharing Functions

All Gateway series have a built-in IP sharing function. The settings and instructions at a PC end are 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

: 192.168.3.1
