Basic Network Settings

This section describes the basic network settings on the IP phone.

DHCP

The IP phone is capable of querying a DHCP server, allowing a network administrator a centralized and automated method of configuring various network parameters for the phone. If DHCP is enabled, the IP phone requests the following network information:

•Subnet Mask

•Gateway (i.e. router)

•Domain Name Server (DNS)

•Broadcast Address

•Network Time Protocol Server

•IP Address

•TFTP Server Name

Note: For DHCP to automatically populate the IP address or domain name for the TFTP server, your DHCP server must support Option 66. Option 66 is responsible for forwarding the TFTP server IP address or domain name to the phone automatically. If your DHCP server does not support Option 66, you must manually enter the IP address or domain name for the TFTP server into your IP phone configuration.

The network administrator chooses which of these parameters (if any) are supplied to the IP phone by the DHCP server. The administrator must configure the phone manually to provide any required network parameters not supplied by the DHCP server.
