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 7940G and 7960G IP Phone loads are signed and can only be upgraded or downgraded to other signed releases.
The P0S3-08-9-00 firmware uses signed (authenticated) files. This step improves IP phone security on the Cisco IP Phone model 7940G and 7960G.
Note:
For the Cisco IP phones 7940 and 7960, you should not add the
extension of .sbn or .bin to the firmware version name in the Cisco Call
Manager database.
Note: You must install Cisco Unified Call Manager version 5.0 or higher to utilize the 8.9 SIP firmware image.
The 8.9 installation programs for the 7940G and 7960G are listed below.
