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) firmware uses signed
(authenticated) files. This step improves IP phone security on the Cisco IP
Phone model 7941G and 7961G.
Before using the Cisco Unified IP Phone models 7941G or 7961G with
Cisco Unified CallManager release 3.3 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 3.0, 3.1, or 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) 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) 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.
Firmware Upgrade caveats for the Cisco IP phones
7941G and 7961G:
· If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, or 7941G-GE and want to upgrade to
8.0(x), be aware that upgrading will take up to twice as long to complete as usual.
Perform the following procedure:

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. For Cisco
Unified CallManager release 5.0 and later are based
on a Linux server platform.
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 IP Phone Model 7941G/7961G
Firmware version 8.5(2) 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-sccp.8-5-2.zip.
After unzipping the firmware files, they
should be manually copied to the appropriate directory on the TFTP server.
