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 8.5(2) SR1 firmware uses signed (authenticated) files. This step improves IP phone security on the Cisco IP Phone model 7941G and 7961G.

 

Installing the Firmware Load

Before using the Cisco Unified IP Phone models 7941G or 7961G with Cisco Unified CallManager release 4.3(2) 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 Release earlier than 4.3(2), do NOT install this firmware.  You must first upgrade your Cisco Unified CallManager to the compatible releases listed in Table 1.

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 8.5(2) SR1 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 8.5(2) SR1 installation programs for the 7941G and 7961G are listed below.

 

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