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 above-mentioned
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.

8. MGCP (Media Gateway Control Protocol)
8.1. IP Phone Configuration
8.1.1. Infrastructure Requirements
Though 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 upgrading. The TFTP server
should have the two software image files (dph80v1.tfp and dph80v2.tfp) from D-Link in
the current directory of the TFTP server selected by ‘set path’.
8.2. 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
ill it gets the response from Media
Gateway Controller
. If it does not get 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.
t
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.
