New and Changed Information
The following sections provide information about changes in this firmware release.
New Software Features
The following new software features are supported in the P00305000500 and P00405000500 firmware releases for Cisco IP Phone 7960, 7940, and 7910 series that are running on Cisco CallManager Release 3.3, 3.2, and 3.1.
Image Authentication and Signed Binary Files
Cisco has added image authentication to its various IP phone protocols. The addition of image authentication prevents tampering with the binary image prior to it being loaded into the phone. Any tampering with the image causes the phone to fail the authentication process and reject that image. The image authentication occurs through signed binary files.
The P00305000500 and P00405000500 firmware releases do not use regular binary files, as did previous releases, but only use signed (authenticated) binary files. This step improves IP phone security on the Cisco IP Phone models 7910 and 7940/60.
Note After you have installed the P00305000500 or P00405000500 firmware release, you cannot install any unsigned release on the phone. You can upgrade to newer signed (authenticated) releases, or downgrade to older signed releases (such as P00305000101) but be aware that only signed images will function on the phone.
You must upgrade the Cisco IP Phone 7914 Expansion Module to firmware release S00103020003 before you install the authenticated 7940/60 phone load.
If you revert the cluster to Cisco CallManager Release 3.1 or 3.2, the P00305000500 or P00405000500 firmware release will function on these Cisco CallManager versions. If you have an unsigned default firmware image, the IP phone will be unsuccessful in its attempt to load the default image (because it is not signed), and will display the "file not found" message on the LCD screen. The Cisco IP Phone will then log an error of "file not found" in the CCM event log, but will continue to function by using the P00305000500 or P00405000500 firmware image that was previously installed on the phone.
Cisco will provide all defect fixes for Cisco CallManager 3.1, 3.2, and 3.3 firmware loads in firmware load P00305000500 and P00405000500 and later.
Cisco IP Phone 7914 Expansion Module
If you are using the Cisco IP Phone 7914 Expansion Module, you must upgrade the Expansion Module to firmware release S00103020003 before you install the firmware release 5.0(5) for the Cisco IP Phone models 7940 and 7960. You can download the installation program, which is named cmterm-7914.S001-3-2-3.exe, from CCO at the same location as the installer for the 5.0(5) software.

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
