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 Dial-
Up Connections.
Right-click on Local Area Connection (LAN).
Click on Properties.
7
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 NA T , 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.

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 W AITING: 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.

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 .
