DVG-5004S/5008S User’s Manual Product Overview

1. Introduction

1-1 Product Overview

The DVG-5004S/5008S VoIP Gateway carries 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 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 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.

2. Installation and Applications

2-1 Network Interface

The network interface is divided into three basic modes as described below:

y Gateway can be assigned a Public IP Address y Gateway can be built under the existing NAT y Gateway can be assigned a Public IP address and serve as an IP-sharing router.

NOTE: The Network Interface function mode setup is accessed through a web UI.

Gateway Assigned a Public IP Address

The gateway will have a public IP address for Internet connection regardless of whether the IP is a static IP address, DHCP (using a Cable Modem), or PPPoE (Dial-up / ADSL).

Gateway IP Settings

NAT/STUN Settings

Need to be set up as static IP, DHCP, or PPPoE

(Please refer to page 14 for information on using NAT.)

DDNS Settings

(Please refer to page 14 for information on DDNS settings.)

Please avoid IP addresses in the following range:

192.168.8.1-192.168.8.254 (You may need to change the settings of IP sharing or change SIP series gateway LAN Port IP addressing)

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

Enable

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

The WAN of the IP sharing device has a dynamic IP address.

If the WAN of the IP sharing device has a static IP address, then the NAT IP address is set as the Public IP address for IP sharing.

If the WAN of the IP sharing device uses a dynamic IP address, then the gateway has to comply with the DDNS settings. When using NAT, you must enter the URL (Uniform Resource Locator) that is registered to the DDNS server.

Disabled

Enabled: enter the registered URL (Uniform Resource Locator) into the network settings under NAT

DVG-5004S/5008S User’s Manual Gateway Configuration-Web Browser

3. Gateway Configuration – Use Web Browser

The VoIP gateway allows users to configure its settings using a web interface (Web UI). You can access the Configuration Menu by opening a web-browser (e.g., Internet Explorer or Netscape Navigator) and entering the factory default LAN IP address: 192.168.8.254. The IP address of the Web UI is same as the default LAN IP noted elsewhere in this user’s manual.

You can also use an ordinary telephone, connect it to the gateway, and dial ”101” to inquire about the current WAN Port IP address and then use the WAN port to log-in.

Instructions

y Open a Web-Browser (e.g., Explorer, Navigator, Opera, Firefox). y Enter the LAN port IP address. The default LAN port IP address is: 192.168.8.254. y The log-in screen below will appear after you connect. (The factory default settings for Login ID and

Password are blank (i.e., no login ID, no password).)

The gateway does not allow multiple people to configure the gateway simultaneously. Please remember to logout or restart the system if you are not using the web configuration function.

D-Link Systems, Inc. 7

DVG-5004S/5008S User’s Manual Network Settings

3-1 Network Settings (WAN)

The network settings are used to set the gateway’s communication ports, IP configurations, and Phone Book Manager IP settings.

y Current WAN IP Address: The IP address of the WAN port. y Listen Port UDP: It is not necessary to change the protocol of the communication port used by the

gateway, unless it conflicts with ports used by another device in your network.

y RTP Starting Port UDP: The initial value of the port number for transmitting voice data among

gateway(s). Each line requires 2 ports. It is not necessary to change the setting, unless it conflicts with ports used by another network device. For example, if the starting port is 9000, then Line 1 is using ports 9000 and 9001, and Line 2 is using ports 9002 and 9003, and so forth.

DVG-5004S/5008S User’s Manual Network Settings

IP Configuration (Setting WAN Port)

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, enter the “Hostname” and “Vendor Class ID” if required by your local ISP and then click the “Accept” button at the bottom of the screen. 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 required 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. 9

DVG-5004S/5008S User’s Manual Network Settings

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.

correct otherwise the gateway will not be able to access hosts using hostnames instead of IPs.

D-Link Systems, Inc. 10

DVG-5004S/5008S User’s Manual Network Settings

WAN Link Speed

It is used to choose the WAN Ethernet link speed. The default is Auto. Please choose the same speed with Router/Switch/Hub, if VoIP gateway connected to Router/Switch/Hub has the link problem.

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.

Using Phone Book Manager

y Enable Phone Book Manager Server: this allows other gateway users to register the IP address and

telephone number in this Phone Book manager. It is recommended that the unit appointed as the Phone Book Manager use static IP.

y Share Phone Book to Clients: While this option is enabled and the gateway is performing as a Phone

Book Manager, this gateway will append its Phone Book entries to the Manager for other clients to lookup.

y TTL (Time to Live): If a gateway system that is controlled by the Phone Book 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 Book Manager once every 30 seconds.

y Register to Phone Book Manager: To register to the Phone Book Manager. y Gateway Name for Phone Book Manager: The alias registered with the Phone Book Manager. y Phone Book Manager Login Password: Enter the registered password. If this system is serving as

the Phone Book Manager, the set password is also the password used for registering other gateway systems.

D-Link Systems, Inc. 11

DVG-5004S/5008S User’s Manual Network Settings

y Phone Book Manager IP/Domain: Enter the IP address for the Phone Book Manager. (This variable

also supports URL (Uniform Resource Locator).)

y Phone Book Manager Server Listen Port [1 - 665535]: The protocol communication port for

transmitting signals between the Phone Book Manager and other gateway systems. Please confirm whether or not the setting is the same as that of the Phone Book Manager.

3-2 Network Settings (LAN)

y Router: The system serves as a Router with NAT. y Bridge: The system serves as a Bridge between WAN port and LAN port without NAT. (LAN default

gateway will still be accessible for configuration).

DVG-5004S/5008S User’s Manual Network Settings

y Enable DHCP Server: Enable or Disable DHCP server service of the gateway. y IP Pool Starting Address: The first IP address to be assigned to DHCP clients. y IP Pool Ending Address: The last IP address to be assigned to DHCP clients. y IP Pool Uses Other Default Gw: Tick the check box to give DHCP client the other default gateway. y IP Pool Default Gateway: Assign the default gateway and subnet mask to DHCP client. y IP Pool Subnet mask: Assign the default gateway and subnet mask to DHCP client. y Lease Time: The valid period of an assigned IP address. y Domain Name Server Assignment: The DNS information to be assigned to DHCP clients.

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.

y Port of Web Access from WAN: HTTP port for WAN. To change this setting, web configuration must

be accessed via the gateway’s LAN port. The gateway always uses port 80 for HTTP connection via the LAN port.

NOTE: Due to network security concerns, Web Access for WAN port is disabled by default (port

number “0” in this option means disable web access). To enable it, simply enter a valid port number in this field.

y Enable Web UI: When “Enable Web UI” is un-ticked, you cannot access from Web. y Enable Telnet Service: It is to activate Telnet access from WAN or LAN when ticked. You can

configure all settings on web user interface through telnet, such as IP configuration, SIP settings, Provision settings, reset to a default stat, etc.

DVG-5004S/5008S User’s Manual QoS Settings

3-3 QoS Settings

WAN QoS

y 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.

y 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.

LAN QoS

y Priority: The gateway can prioritize LAN ports. Data from HIGH priority port are delivered prior to

those from LOW priority port while they arrive at the same time.

y Flow Control: Enable or Disable Flow control. y Incoming Rate Limit: Set the incoming (from WAN to LAN) rate limit of a specific LAN port (can not

exceed the real downstream bandwidth).

y Outgoing Rate Limit: Set the outgoing (from LAN to WAN) rate limit of a specific LAN port (can not

exceed the real upstream bandwidth).

D-Link Systems, Inc. 14

DVG-5004S/5008S User’s Manual QoS Settings

* VLAN – This feature is only supported for the special hardware.

VLAN is optional. It works with the Router or Switch that supports VLAN. There are 2 VLAN groups: Voice and data (LAN). This improves efficiency of network performance and security.

y Enable VLAN Tagging: It is to tag the packets for VLAN Router or Switch identifying. y VLAN ID: It is to assign uniquely a user-defined ID to each packet. y Priority: It is the proprietary to VLAN Router or Switch.

Note: Please do not change anything here unless requested by your ISP.

D-Link Systems, Inc. 15

DVG-5004S/5008S User’s Manual NAT/DDNS

3-4 NAT/DDNS

NAT Traversal

If your gateway is set up behind an Internet sharing device, you can select either the NAT or STUN protocol. y NAT Public IP: The IP address used by the gateway should be a private address. Furthermore, users

must set Virtual Server Mapping in the Internet sharing device. (For example, a virtual server is usually 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): 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.

DVG-5004: 9000~9023

DVG-5008: 9000~9047

o 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.

y Enable STUN Client: Using the STUN protocol prevents problems with setting the IP sharing function,

but some NATs do not support this protocol.

NOTE: You can use the “Status Æ 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.

y 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.

y 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 Æ Current Status” page will show the status of UPnP.

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.

y Server address: the IP address or URL (Uniform Resource Locator) of the DDNS Server. y Hostname: the URL of the system (or NAT) – applied from domain name registration providers (e.g.

www.dyndns.org).

y Login ID and Password: The ID and password used to log-in to the DDNS server. y 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.

y FXS Caller ID Generation: Select this option to enable the caller ID display function on FXS ports.

When enabled, the caller’s phone number will be displayed on your phone set when the call comes through. FSK is preferred in some countries.

y Send Caller ID After The First Ring: When enabled, the caller’s phone number will be sent to your

phone set after the first ring-on. When disabled, caller id will be sent before the First ring-on.

y FSK Caller ID Type: Bellcore is used in North America and ETSI is used in EU. y Anonymous Caller ID (CLIR): When enabled, anyone receiving a call from you will not display your

number if they have caller ID.

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

DVG-5004S/5008S User’s Manual Telephony Settings

3-6 Telephony Settings

y 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

y FXS port: When the user picks up the phone, the gateway automatically dials your assigned hotline

number. When in hotline mode, other phone numbers cannot be dialed.

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

Example:

Assume that the assigned hotline for DVG-5004S/5008S line 1 is 701 and the Warm Line (Hot Line Delay) is five seconds. If no extension number is dialed within five seconds, the call will be automatically diverted to the assigned hotline (ext. 701). The system allows users to record a voice prompt (e.g. “please enter an extension number or wait for the operator to connect you”) to use in this situation.

Assume that the assigned hotline for DVG-5004S/5008S line 2 is 702 and the wait time is 0 seconds. When Port 2 receives a call from an outside line, it will be automatically diverted to extension 702.

y FXS Group: Select group hunting when there is an incoming call and the gateway will automatically

assign an unassigned call according to the 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.
