New Cisco IP Phone Software Features

The following new software features are supported in the P00307020200 firmware release for the Cisco IP Phone models 7960G and 7940G that are running on Cisco CallManager Release 4.1(2) and later.

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 You can find more details about these features in the Cisco IP Phone 7960G/7940G Guide


Table 1 New Software Features in this Release 

Feature
Description

Proxy EAPOL-Logoff

Support for secure attachment of IEEE 802.1X supplicant (such as a PC) to the Cisco IP  Phone 7960/40 PC port.

Signaling Encryption

Support for AES256-SHA-AES12-SHA encryption in a transport layer security (TLS) session with Cisco CallManager to encrypt Skinny Call Control Protocol (SCCP) messages. This allows for encrypted registration with Cisco CallManager and is a mandatory requirement for supporting media encryption.

Media Encryption

Support for Secure Real-time Transport Protocol (SRTP ) to encrypt the voice stream, allowing for encrypted calls.

Phone Security for Cisco IP Phone models 7960G and 7940G

The 7.2(x) firmware releases that are running on Cisco CallManager 4.1(2) and later now support encrypted calls. You can configure the security mode to enable encrypted registration and encrypted calls.

Phone Security User Interface (UI)

Adds a Security Configuration menu and icons for displaying registration and call security mode to the Cisco IP Phone models 7960G and 7940G.

Secure Survivable Remote Site Telephone (SRST)

For systems that are running SRST, provides authenticated and encrypted signaling in a TLS session with an SRST device.

Locally Significant Certificate (LSC) update automation

You can remotely manage LSC updates by using a configuration file. Phones can automatically initiate sessions with the Certificate Authority Proxy Function (CAPF ) to update their certificates.

CAPF IP Address and Port

You can configure the CAPF IP address and port from the configuration file. In this release, the port is no longer hard coded in the phone.


Secure PC Log Off in an 802.1X Network

Firmware release 7.2(2) 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(2) 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.html

Upgrading from Firmware Release 6.0(5)

If you are upgrading from firmware release 6.0(5), note that the "Known and Resolved Problems" section is a cumulative list of problems since firmware release 7.0(2). To see the list of resolved problems in firmware release 7.0(2), refer to the Cisco IP Phone 7960G/7940G Release Notes for Firmware Release 7.0(2).

Resetting 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 From the main screen, press Settings to display the Settings screen.

Step 2 Enter **#** by using the keypad.

The IP phone goes through the reset cycle.


Note This reset sequence also works from any other screen that does not accept user input.



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 S00104000100 before you install the Cisco IP Phone firmware release 7.2(2). 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/pcgi-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:

Procedure


Step 1 From the main screen, press Settings to display the Settings options.

Step 2 Choose Network Configuration.

Step 3 Scroll to PC VLAN (parameter 58).


Note The parameter setting is disabled if blank.

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.
