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 7942G and 7962G IP Phone loads are signed and can only be upgraded or downgraded to other signed releases.

The 8.5(2) firmware uses signed (authenticated) files. This step improves IP phone security on the Cisco IP Phone model 7942G and 7962G.

Before using the Cisco Unified IP Phone models 7942G or 7962G 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.
