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.
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.

For Cisco Unified CallManager 5.0, you must do all software installations and upgrades by using the Software Upgrades menu options. The system can upload and process only software that Cisco Systems approved. You cannot install or use third-party or Windows-based software applications that you may have been using with a previous version of Cisco Unified CallManager with Cisco Unified CallManager 5.0.
The Cisco Unified IP Phone Model 7941G/7961G Firmware version 9.2(3) is also supplied in a zip file, as an alternative in case a Cisco Unified CallManager is not available to run the executable installer program. The name of this file is cmterm-7941_7961-sip.9-2-3.zip.
After unzipping the firmware files, they should be manually copied to the appropriate directory on the TFTP server.
