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 7940 and 7960 IP Phone loads 5.0 and newer are signed and can only be upgraded or downgraded to other signed releases.

The P00308010200 firmware uses signed (authenticated) files.  This step improves IP phone security on the Cisco Unified IP Phone models 7940 and 7960.


Installing the Firmware Load

Note: For the Cisco Unified IP Phone models 7940 and 7960, you should not add the extension of .sbn or .bin to the firmware version name in the Cisco Unified Communication Manager database.
