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 7941G and 7961G IP Phone loads are signed and can only be upgraded or downgraded to other signed releases.

The 9.2(3) firmware uses signed (authenticated) files. This step improves IP phone security on the Cisco Unified IP Phone 7941G and 7961G.

 

Installing the Firmware Load

Note: You must install Cisco Unified CallManager version 5.0 or later to utilize the 9.2(3) SIP firmware image.

 

The 8.0(1) firmware release has been made available on Cisco Unified CallManager installation CDs; however, it will not be made available on Cisco.com due to additional bugs filed during final testing. Cisco recommends that you instead use the updated 9.2(3) firmware load, which is now available on Cisco.com. This recommendation is limited to this specific firmware release and has no bearing on any other software or firmware available on Cisco Unified CallManager CDs.

The 9.2(3) installation programs for the Cisco Unified IP Phone 7941G and 7961G are listed below.

 

Note: For the Cisco Unified IP phones 7941G and 7961G, you should not add the .loads extension to the firmware version name in the Cisco Unified CallManager database.
