Using H.323 Protocol
IP Phone Configuration
Infrastructure Requirements
Although the DPH-80 H.323 phone will work in any type of LAN network, a
100mbps, switched network is more suitable for providing good quality voice
communications.
H.323 phones need a Gate Keeper (GK) to provide the directory function required
to make calls. The DPH-80 H.323 phone registers the assigned phone number
with the server on power-up. However, the D-Link H.323 phone can work through
the phone book without a H.323 GK.
To operate properly, H.323 phones require a set of IP parameters for proper
functioning such as an IP address, IP mask, gateway address, and DNS server
address. These parameters can be configured either statically through a browser
or dynamically through DHCP. A DHCP server in the local LAN is required to
provide these parameters.
The DPH-80 H.323 phone has many configurable parameters. These
parameters can be configured through any Java-enabled Internet browser (like
Netscape 6.2 or above, IE 5.0 or above).
If your LAN network has a firewall and NAT, they should support H.323 for making
and receiving calls from outside your LAN network.
A
TFTP
server is required if you want to support remote software upgrades.
Please check with your service provider for further information on upgrading
your device.
