New Cisco IP Phone Software Features
The following new software features are available with Cisco CallManager Release 4.1(2) and supported in the P00307020400 firmware for the Cisco IP Phone models 7960G and 7940G.
For a complete list of all new features in Cisco CallManager Release 4.1(2), refer to the Release Notes for Cisco CallManager Release 4.1(2).
Note
Secure PC Log Off in an 802.1X Network
Firmware release 7.2(4) provides support for the Cisco IP Phone models 7960G and 7940G to monitor IEEE 802.1X messages between an authenticating switch and a connected PC (supplicant).
When a PC is disconnected from the Cisco IP Phone, the phone issues an EAPOL-Logoff message on behalf of the PC to the authenticating switch. The proxy EAPOL-Logoff message causes the authenticating switch to set the PC port on the phone to an unauthenticated state and immediately terminates the 802.1x secure session.
If you have an 802.1X network and upgrade to Cisco IP Phone firmware release 7.2(4) or greater, be aware that you must re-authenticate a PC that is connected to a Cisco IP Phone 7940/60 after the upgrade.
For more information about 802.1X re-authentication, refer to the Cisco Catalyst switch configuration guides at:
http://www.cisco.com/en/US/products/hw/switches/tsd_products_support_
category_home.htmlUpgrading from Firmware Release 6.0(5)
If you are upgrading from a previous firmware release, note that the "Known and Resolved Problems" section is a list of problems since the last firmware release 7.2(3). To see the list of resolved problems in other firmware releases, refer to this URL:

ipp7960/relnotes/index.htmResetting a Cisco IP Phone Model 7960 or 7940
In previous releases, you could enter the reset code when a phone was on-hook at the main phone screen. With this release, you can no longer reset the phone from the main screen; instead, you must use the Settings screen or any other screen that does not accept user input. This new behavior results from a customer requirement to allow beginning a dialing sequence with * or # while the phone is on-hook.
To reset a Cisco IP Phone model 7960 or 7940, follow these steps:
Procedure
Step 1
Step 2
The IP phone goes through the reset cycle.
Note
Cisco IP Phone Expansion Module 7914
If you are using the Cisco IP Phone Expansion Module 7914, you must upgrade the Expansion Module to firmware release S00104000100 before you install the Cisco IP Phone firmware release 7.2(4). You can download the installation program, which is named cmterm-7914-sccp.4-0-1.exe, and the readme file from Cisco.com at this location:
http://www.cisco.com/cgi-bin/tablebuild.pl/ip-7900ser
Configurable SRST Router Fallback Waiting Period
When a Cisco IP Phone loses its connection to the Cisco CallManager server, the connection fails over to an SRST router. After a failover to an SRST router, the phone will monitor the links to the Cisco CallManager servers that the phone can register to. When a server has been available for two minutes, by default, the phone will fall back from the router to that server.
You can change this default time by specifying another value for the station connection monitor duration parameter in Cisco CallManager Administration. For more information, refer to Cisco CallManager Administration Guide.
Using Barge on an Encrypted Call
Cisco IP Phone models 7960G and 7940G users cannot barge into an encrypted call if the phone that is used to barge is not configured for encryption. When barge fails in this case, a fast busy tone plays on the phone where the user initiated the barge. No error message displays on the initiator phone to indicate that barge failed because the call is encrypted.
If the initiator phone is configured for encryption, the barge initiator can barge into an authenticated or nonsecure call from the encrypted phone. After the barge occurs, Cisco CallManager classifies the call as nonsecure.
If the initiator phone is configured for encryption, the barge initiator can barge into an encrypted call, and the phone indicates that the call is encrypted.
A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The authentication icon continues to display on the authenticated devices in the call, even if the initiator phone does not support security.
Configurable Parameter for PCs on a VLAN
When PCs are connected to Cisco IP Phones, a new IP phone parameter enables phones to strip the 802.1p/q tags from packets as they exit the phone PC port. This parameter applies to systems that use voice VLANs with non-Cisco switches. The parameter is available only when the Admin VLAN is active.
The parameter setting is disabled when it is blank. If the parameter has any value (from 1-4094), the phone will strip tags from all VLANs. For example, if PC VLAN = 123, then tags from VLAN 123 and all other VLANs will be stripped.
To access the new PC VLAN parameter, follow these steps:

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—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.
Severity 2 (S2)—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.
Severity 3 (S3)—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.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
