Getting Started

Overview

The D-Link DPH-80 is a low cost, simple to use, and extremely versatile IP phone with the look and feel of a normal PSTN phone.

The D-Link IP Phone can operate under any of the three main Internet telephony protocols: Media Gateway Control Protocol (MGCP); Session Initiation Protocol (SIP); and the H.323 protocol. These protocols are used for signaling, maintaining, and tearing down voice calls. The D-Link IP phone allows voice data to be carried over the same path used by your computer for the Internet or Local Area Network (LAN).

The D-Link DPH-80 phone is easy to install and supports plug and play features of the IP network. Out of the box, your IP phone will work in any of the abovementioned three protocol infrastructures with minimal configuration. Advanced, customized configuration is easily achieved through a web-browser configuration utility.

D-Link IP phones support remote maintenance, allowing software to be upgraded remotely for new features and any bug fixes. The DPH-80 supports a unique remote diagnostic feature to monitor phone functions and performance.

Installation

The following are steps will install and power-on your DPH-80 IP phone:

Connect the RJ-45 Ethernet cable from the DPH-80 to a LAN jack.

Plug the power adapter into the appropriate wall outlet.

Plug the power adapter plug into the power jack.

Getting Started

Configuring the IP Address

In order to use a Web browser to configure the DPH-80 IP phone, you must make sure the phone has a valid Ethernet connection to a PC or LAN via its Ethernet port. We recommend using a recent version of any widely used browser such as Netscape or Internet Explorer. The browser must have JavaScript enabled. The following illustrations use Windows 2000 and Internet Explorer 5.5.

The DPH-80 comes with a default IP address of 10.1.1.80. Make sure that the IP address on your Ethernet card is in the same subnet as the DPH-80. You can do this by changing the IP address of the PC as shown.

In Windows, go to Start/Settings/Control Panel/Network and DialUp Connections.

Right-click on Local Area Connection (LAN).

Click on Properties.

Getting Started

Configuring the IP Address

In the General Tab, click on Internet Protocol (TCP/IP).

Click on Properties.

Getting Started

Configuring the IP Address

Click on Use the following IP address, and enter a value in the 10.1.1.xx range. (Do not use the IP address 10.1.1.80; this address is already in use by the DPH-80 as a default address.) Change your IP address on your Ethernet adapter to 10.1.1.x, where x is something other than 80. Make sure the subnet mask and default gateway match the DPH-80. This should allow you to use the Web interface to configure the IP phone.

Click OK.

Open Internet Explorer. Click on Tools/Internet Options/Connections

Click on LAN Settings.

Getting Started

Configuring the IP Address

Make sure Use a proxy server is disabled.

Click OK.

Loading Factory Defaults

If it is required to reset the DPH-80 and start with default configuration parameters, you can do so by pressing ‘*789*#’ while the phone is in the idle state. The phone will restart in a few seconds with the default parameters. The default configuration password is ‘12345’. The phone’s Internet access and calling card information must be configured again before it can be used.

Note: Upon pressing ‘*789*#’, the DPH-70 will ask for confirmation.

Advance Configuration

The DPH-80 is highly versatile and can be configured to operate in any of the three main Internet telephony protocols – MCGP, SIP, and H.323.

The following sections contain configuration details, instructions for use, and a troubleshooting guide for each protocol.

Using Media Gateway Control

Protocol (MGCP)

Infrastructure Requirements

Although the DPH-80 MGCP phone will work in any type of LAN network, a 100mbps, switched network is more suitable for providing good quality voice communications.

MGCP phones need a Media Gateway Controller or Call Agent or Notified Entity.

To operate properly, the DPH-80 needs a set of IP parameters such as IP address, subnet mask, gateway address, and DNS server address. These parameters can be configured either statically through a browser or dynamically through DHCP or PPPoE. A DHCP or PPPoE server in the local LAN is required to provide these parameters.

The D-Link MGCP phone has many configurable parameters. These parameters can be configured through any Java-enabled Internet browser (Netscape 6.2 or above, IE 5.0 or above).

If your LAN network has a firewall and NAT, they should support MGCP to make and receive calls from outside your LAN network.

A TFTP server is required to support remote software upgrades. Please check with your service provider for further information on upgrading your device.

Configuring the MGCP Phone

Once you have the above infrastructure in place, you can power up the MGCP phone. The MGCP phone will play the progress tone until it receives a response from Media Gateway Controller. If it does not receive the dial tone within the expected time, the MGCP phone is not configured. However, the MGCP phone is accessible through an Internet browser for configuration.

Using Media Gateway Control Protocol (MGCP)

Configuring the MGCP Phone

To access the web interface for the D-Link DPH-80:

Use a JavaScript-enabled Internet browser (Netscape 6.2 or above, IE 5.0 or above) with the default IP address of the DPH-80 entered in the address box (http://10.1.1.80).

The following page will appear.

The following two parameters control access to the MGCP phone. The default value for both is“dlink”. These values can be changed later using the Change Login Name and Password Page.

User Name: This is case-insensitive with a maximum of 20 characters.

Password: This is case-insensitive with a maximum of 20 characters.

Click Submit.

Calling Features

MUTE: When pressed, the MGCP phone turns off the microphone signal from the handset but still plays voice from the other party.

HOLD: When pressed, the MGCP phone disconnects both microphone and speaker while the connection is kept alive. No voice packets are transmitted from the D-Link MGCP phone. The hold LED is on. The user may press the button again to release the call. This feature requires support from the remote phone for proper functioning.

REDIAL: When pressed, the phone redials last dialed number.

TRANSFER: Toggle the hook-switch quickly to flash (transfer) the call. The MGCP phone plays a dial tone. Then enter the party to transfer the call by the general dialing method. The MGCP phone transfers the call and plays a busy tone. Flashing the hook twice before dialing the number will restore the call to the normal state (to call-active state).

SPEAKERPHONE: One-touch dialing key. When pressed, the speaker LED is on and speaker itself is on while on-hook. If user off-hooks after dialing or presses this button again the one-touch operation is terminated,and the LED and speaker are both turned off.

Note: This is not a true speakerphone, but is designed to allow one-touch dialing. Although the other party can hear through the speakerphone, the voice quality is very poor.

CALL WAITING: The call-waiting tone will be played whenever a new party calls while a call is in progress. By pressing the hook-switch the MGCP will switch to the incoming call. Pressing again will switch between two parties.

Algorithms

Codecs: D-Link MGCP phones supports G.711 U/A law, G.723.1, and G.729AB. The browser configuration allows selecting codecs and their priority.

Voice activity detection, silence suppression, and comfort noise generation: The VAD can be disabled in the configuration irrespective of the codec being used.

Adaptive Jitter Buffer: D-Link MGCP phones use a robust adaptive jitter buffer algorithm. It can be disabled and a fixed-size jitter buffer can be used instead through configuration.

Other Features

Remote software upgrade: A predefined key sequence will download the MGCP phone software and restart the phone. The MGCP phone should have been configured with the correct TFTP server IP address.

Remote diagnosis: The MGCP phone will send status and other messages to the log server configured in the MGCP phone. The remote log server should run the server application from D-Link to receive and display these messages. This feature can be disabled through the browser.

Restore factoy defaults: If you enter the specified key sequence, the MGCP phone restores the configurable parameters to default values upon next restart.

Production testing: If you enter the specific key sequence, the D-Link MGCP phone will execute a production test upon the next restart. The production test is described later in this section.

MGCP Troubleshooting

Error Conditions

The D-Link MGCP phone will detect the following error conditions and play the error tone.

Error tone on network-connection failure.

Upon network connection, the tone will revert to normal dial tone. The link LED also gives this information.

Error tone if there is no DHCP server.

The phone will revert to a normal dial tone upon detecting a DHCP server.

Error tone if the MGCP proxy is down on power-up.

The phone will revert to a normal dial tone upon detecting an MGCP server.

Some common error situations are described below.

Power UP

There is no tone on power-up.

Check the power adaptor and power source, and restart the phone.

There is no dial tone on power-up.

The MGCP phone takes time to exchange information with DHCP and MGCP call agent. During this time it will play call progress tone. Then the tone will change to a dial tone if the DHCP and connection with the call agent is successful. It will play an error tone if the DHCP or call agent fails.

The phone plays an error tone on power-up.

It means that the information exchange with DHCP or MGCP call agent has failed. Check your network connection and confirm that the DHCP and MGCP call agents are running. Also, restart the phone to check if the MGCP phone is configured properly.
