•Other DHCP Options You Can Set, page 6-7

The procedures in the following sections instruct you to set various parameter values using a phone’s configuration menus or web page. For information about phone menu configuration and parameters, see Chapter 5, “Configuring the Cisco IP Phone Models 7905G and 7912G Using the Phone Menus.” For information about web page configuration, see Chapter 7, “Configuring the

Cisco IP Phone Models 7905G and 7912G Using Web Pages.” For information about web page parameters, see the “Network Parameters” section on page 8-2.

You can configure parameters through configuration menus on a phone without first obtaining network connectivity for the phone. If you want to configure a parameter using the phone’s web page, you first must obtain network connectivity by statically configuring IP with the settings as explained in the “Minimum Configuration Settings for the Cisco IP Phone Models 7905G and 7912G” section on page 3-9.

If the DHCP Server is Under Control of the Cisco IP Phone Administrator

If you as the Cisco IP Phone administrator control the DHCP server, follow these steps to make appropriate DHCP server configuration settings:

Procedure

Step 1 On the DHCP server, set one of the following options:

•DHCP option 150 (TFTP server IP address)

•Standard DHCP option 66 (TFTP server name)

If you use DHCP option 150, the Cisco IP Phone will ignore DHCP option 66. However, if you use DHCP option 66, you must turn off DHCP option 150 or set its value to 0.

Note You can turn off the DHCP option 150 request by using OpFlags parameter. See the “Network Parameters” section on page 8-2.
