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 7975G IP Phone loads are signed and can only be upgraded or downgraded to other signed releases.
The 9.4(2) firmware uses signed (authenticated) files. This step improves IP phone security on the Cisco Unified IP Phone 7975G.
Before using the Cisco Unified IP Phone 7975G 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.
Note: If you have a Cisco Unified CallManager on a Release earlier than 4.1(3)SR5, do NOT install this firmware. You must first upgrade your Cisco Unified CallManager to one of the compatible releases listed in Table 1.

Please note that different versions of the installer are needed for different Cisco Unified CallManager releases. Cisco Unified CallManager releases earlier than 5.0 are based on a Windows server platform. Cisco Unified CallManager release 5.0 and later are based on a Linux server platform.
For Cisco Unified CallManager 5.0 (and later), 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 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 7975G Firmware version 9.4(2) is also supplied in a zip file, as an alternative in case a Cisco Unified CallManager is not available to load the installer program. The name of this file is: cmterm-7975-sccp.9-4-2-1.zip.
After unzipping the firmware files, they should be manually copied to the appropriate directory on the TFTP server.
