Chapter 8 Profile and Web Page Parameters and Defaults

Parameter Details

future upgrades. A phone that can perform image authentication will only request a .sbin file. If the profile of a phone that can perform image authentication specifies a .zup firmware image instead of a

.sbin firmware image, the phone will automatically modify the request to obtain a .sbin firmware image. (A Cisco IP Phone 7912G will always request a .sbin image.)

The default value for the upgradecode parameter is:

3,0x501,0x0400,0x0100,0.0.0.0,69,0,none

Use this default value as a starting point when you enter a value. (This default value includes 0x501 for a Cisco IP Phone 7905G. If you are using a

Cisco IP Phone 7912G, make sure to change 0x501 to 0x601.)

Process

When you store a new firmware image on the TFTP server and you update image_id in the upgradecode parameter, the Cisco IP Phone upgrades its firmware with the new image. The phone contacts the TFTP server that is specified by tftp_server_ip in the upgradecode parameter.

Example

upgradecode:3,0x501,0x0400,0x0100,192.168.2.170,69,0x030609a,CP7905010

1SIP030609A.zup

This parameter setting instructs a Cisco IP Phone 7905G to upgrade its firmware to CP79050101SIP030609A.zup by downloading this file from the TFTP server IP address of 192.168.2.170. This download occurs after the phone downloads its configuration file that contains the upgradecode parameter and only if the phone’s internally-cached image_id is different than the value 0x030609a.

Upgradelogo Parameter Detail

When the Cisco IP Phone is not in use for a call, a figure appears on the LCD screen above the soft key labels and below the time and date. Using TFTP configuration, you can change this figure to one that you provide. For example, you might change the figure to your company logo.
