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 7942G and 7962G IP Phone loads are signed and can only be upgraded or downgraded to other signed releases.

The 9.4(2)SR3 firmware uses signed (authenticated) files. This step improves IP phone security on the Cisco Unified IP Phone 7942G and 7962G.

Installing the Firmware Load

Before using the Cisco Unified IP Phone 7942G or 7962G with Cisco Unified CallManager release 5.1(1b) 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 5.1(1b), do NOT install this firmware. You must first upgrade your Cisco Unified CallManager to one of the compatible releases listed in Table 1.

The 9.4(2)SR3 installation programs for the Cisco Unified IP Phone 7942G and 7962G are listed below.

Note: For the Cisco Unified IP phones 7942G and 7962G, you should not add the .loads extension to the firmware version name in the Cisco Unified CallManager database.

Note: To improve software integrity protection, new public keys are used to sign cop files for Cisco Unified Communications Manager Release 10.0.1 and later. These cop files have "k3" in their name. To install a k3 cop file on a pre-10.0.1 Cisco Unified Communications Manager, consult the README for the ciscocm.version3-keys.cop.sgn to determine if this additional cop file must first be installed on your specific Cisco Unified Communications Manager version. If these keys are not present and are required, you will see the error "The selected file is not valid" when you try to install the software package.
