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.
