New and Changed Information

New Software Features

The following new software features are supported in the P00305000300 and P00405000300 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 P00305000300 and P00405000300 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 P00305000300 or P00405000300 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.

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 authenticated 7940/60 phone load.

---

If you revert the cluster to Cisco CallManager Release 3.1 or 3.2, the P00305000300 or P00405000300 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 IP Phone will then log an error of "file not found" in the CCM event log, but will continue to function by using the P00305000300 or P00405000300 firmware image that was previously installed on the IP phone.

Cisco will provide all defect fixes for Cisco CallManager 3.1, 3.2, and 3.3 firmware loads in firmware load P00305000300 and P00405000300 and later.

Table 2 Known Problems 

Bug ID	Summary	Explanation
CSCeb35494	After entries are added to the Phone Address Book, access to those entries intermittently fails.	After subscribing the Cisco IP Phone to the Phone Address Book service and adding entries using Cisco CallManager, details of the entries cannot be displayed on the phone. When you attempt to either see the details of an entry or add a new entry to the phone, the error message "error-1[internal error]List is not a part of the session" is displayed.

Cisco IP Phone intermittently sends an incorrect IP address in the OpenReceiveChannel Ack packet that is sent to Cisco CallManager. Workaround: Reboot the phone by unplugging the Ethernet cable from the back of the phone and then plugging it back in.
CSCeb82780	DSP mismatch with signed image results in Cisco IP Phone upgrade failure.	When the Cisco IP Phone image is upgraded, the image might fail signature verification due to a corrupt image or failed authentication. This results in a DSP mismatch; the incompatibility between the image and the DSP causes the phone to be inoperable. Workaround: Reload the phone with a good known image.
CSCeb85080	Cisco IP Phone repeatedly displays "DSP Keepalive Timeout" message.	On rare occasions, the Cisco IP Phone might repeatedly display the "DSP Keepalive Timeout" message at the time the phone is powered up or during a call. Workaround: None.

Opening a TAC Case

The online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4 cases. (Your network is minimally impaired or you require product information). After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using these recommendations, your case will be assigned to a Cisco TAC engineer.

For P1 or P2 cases (your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

To open a case by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

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.
