Image Authentication Support

Cisco provides image authentication with its various IP phone protocols.  Image authentication allows the phone to detect if the image has been tampered with before it is programmed into the phone. If the image fails the authentication process then the phone will reject the image.  Image authentication occurs through signed files.  All Cisco 7975G IP Phone loads are signed and can only be upgraded or downgraded to other signed releases.

The 9.4(2) firmware uses signed (authenticated) files. This step improves IP phone security on the Cisco Unified IP Phone 7975G.

 

Installing the Firmware Load

Before using the Cisco Unified IP Phone 7975G with Cisco Unified CallManager release 4.1(3)SR5 or later, you must install the latest firmware on all Cisco Unified CallManager servers in the cluster.

 

Note: If you have a Cisco Unified CallManager on a Release earlier than 4.1(3)SR5, do NOT install this firmware.  You must first upgrade your Cisco Unified CallManager to one of the compatible releases listed in Table 1.
