This section describes the new features and changes for this release of the Cisco Wireless IP Phone 7920.

Cisco IP Phone Services and Features

Security Features

Support for Cisco CallManager Release 4.0 Phone Features

Cisco CallManager Administration Changes

Cisco 7920 Configuration Utility Changes

Text Entry Enhancements

Distinctive Rings and Tones

Cisco CallManager Extension Mobility Support

Cisco IP Contact Center (IPCC) and IPCC Express Support

Cisco IP Phone Services and Features

Cisco Wireless IP Phone 7920 users can access IP Phone services and XML applications by using a new directory option on the phone called Services. Examples of these IP phone services can include these:

Web-based information such a stock quotes, movie listings, and weather reports

Network data, such as corporate calendars and searchable directories

The administrator can use the Idle URL setting to display information or graphics on the idle Cisco Wireless IP Phone 7920 screen.

Security Features

To improve wireless network security, the Cisco Wireless IP Phone now supports these security features:

WiFi Protected Access (WPA) that provides centralized authentication on a RADIUS server.

WPA Pre-shared Key authentication that provides authentication by exchanging a password phrase between the access point and phone.

Cisco Centralized Key Management (CCKM) and a wireless domain server (WDS) that provides fast reauthentication when roaming.

Temporal Key Integrity Protocol (TKIP) and Message Integrity Check (MIC) that improves encryption. TKIP provides per-packet encryption ciphering and longer initialization vectors (IVs) that strengthen encryption and remove the predictability of Wired Equivalent Protocol (WEP). MIC ensures that encrypted packets are not being altered.

For more information about using these security features, refer to "Overview of the Wireless Network" chapter in the Cisco Wireless IP Phone 7920 Administration Guide.

Support for Cisco CallManager Release 4.0 Phone Features

The Cisco Wireless IP Phone 7920 now supports the phone features available with Cisco CallManager, Release 4.0, including shared lines, conference enhancement features, and multiple calls (2) per line.

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:

Emergencies — security-alert@cisco.com

Nonemergencies — psirt@cisco.com


Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product to encrypt any sensitive information that you send to Cisco. PSIRT can work from encrypted information that is compatible with PGP versions 2.x through 8.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one that has the most recent creation date. For more information, see:

In an emergency, you can also reach PSIRT by telephone:

1 877 228-7302

Obtaining Technical Assistance

For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service contract, contact your reseller.

Cisco Technical Support Website

The Cisco Technical Support Website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, 365 days a year, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do


Note Use the Cisco Product Identification (CPI) tool to locate your product serial number before submitting a web or phone request for service. You can access the CPI tool from the Cisco Technical Support Website by clicking the Tools & Resources link under Documentation & Tools. Choose Cisco Product Identification Tool from the Alphabetical Index drop-down list, or click the Cisco Product Identification Tool link under Alerts & RMAs. The CPI tool offers three search options: by product ID or model name; by tree view; or for certain products, by copying and pasting show command output. Search results show an illustration of your product with the serial number label location highlighted. Locate the serial number label on your product and record the information before placing a service call.


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: 1 800 553-2447

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.
