EAP-FAST Security Feature

To provide more secure authentication in the wireless network, the Cisco Unified Wireless IP Phone 7920 now supports Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling (EAP-FAST). You can use either WEP or Temporal Key Integrity Protocol (TKIP) encryption when using EAP-FAST.

A client server security architecture, EAP-FAST encrypts EAP transactions within a Transport Level Security (TLS) tunnel. The tunnel is based on Protected Access Credentials (PAC) for more secure authentication between the client and the RADIUS server.

Note•The default expiration for a PAC is one week in the Cisco Access Control Server (ACS). If the phone has an expired PAC, it will take approximately 20 seconds longer to authenticate with the RADIUS server while the phone gets a new PAC.

•If you were using LEAP prior to upgrading to firmware release 3.0, be aware that EAP mode may change to EAP-FAST after upgrading the firmware when EAP-FAST is enabled on the RADIUS server. With firmware release 3.0, the default setting for EAP mode is Auto. When using the Auto setting for EAP mode, EAP-FAST has precedence over LEAP.

If the Cisco Unified Wireless IP Phone 7920 firmware is downgraded to 2.0 or earlier and you are using EAP-FAST for authentication, the phone will not be able to authenticate. Firmware Release 2.0 does not support EAP-FAST, so you must use LEAP as your authentication method with earlier releases and enable it on the Cisco ACS.

For more information about configuring and using the EAP-FAST feature, refer to "Overview of the Wireless Network" chapter in the Cisco Unified Wireless IP Phone 7920 Administration Guide.

Cisco Unified Wireless IP Phone 7920 Localization

Release 3.0 firmware provides these translated and localized versions of the phone:

•English

•French

•German

•Japanese

•Norwegian

Prior to upgrading to firmware release 3.0, download the locale installer and configure the languages in Cisco Unified CallManager. For more information, refer to Using the Cisco IP Telephony Locale Installer for Cisco Unified CallManager for your Cisco Unified CallManager release.

Note After modifying the user locale on the Cisco Unified Wireless IP Phone 7920, you must power cycle the phone.

Cisco Unified Wireless IP Phone 7920 for Australia and New Zealand

A version of the Cisco Unified Wireless IP Phone 7920 is now available for the Australia and New Zealand market. To comply with Australia and New Zealand requirements, this model (CP-7920-AU-K9) has a separate buzzer to ring the phone. The buzzer is supported with Version 3.0 firmware.

Because the phone rings only through the buzzer, other ring tones are not supported. All tones, including warning tone, play the same sound. The phone setting, Ring Tone Output, is not applicable to the Australia/New Zealand version of the phone.

The Cisco recommended headset (ear bud) does not comply with Australia and New Zealand requirements; therefore, this headset is not orderable for these regions. Other headsets are not qualified for use with the Cisco Unified Wireless IP Phone 7920.

For more information, refer to the Cisco Unified Wireless IP Phone 7920 Version 3.0 Data Sheet at:

http://www.cisco.com/en/US/products/hw/phones/ps379/products_data_sheet09186a00801739bb.html

Battery Life Improvement for Out of Range

When the Cisco Unified Wireless IP Phone 7920 goes outside of the wireless LAN range, the phone enters a power save mode that reduces scanning. The reduction in scanning can help preserve battery life.

After returning to the coverage area, the user can reconnect to the wireless LAN faster by pressing the Answer/Send (green key). The phone immediately scans all channels and attempts to reconnect to the wireless LAN.

Cisco Unified CallManager Release 4.1 Phone Features

The Cisco Unified Wireless IP Phone 7920 now supports Pickup Group enhancements that include the OPickUp softkey for accessing associated pickup group calls and the auto-pickup system parameter available with Cisco Unified CallManager, Release 4.1.

Cisco Unified CallManager Release 4.2 Phone Features

The Cisco Unified Wireless IP Phone 7920 now supports this phone feature available with Cisco Unified CallManager Release 4.2:

Pickup Notification Enhancements

This new feature allows users to receive an audio and/or visual alert when a call rings on a phone in pickup groups in which they are a member. For multiple line phones, the alert is available for pickup groups associated with the primary line only.

You can configure these notification parameters in the Call Pickup Group Configuration window:

•Type of notification (audio, visual, both, or neither)

•Content of the visual notification message (called party identification, calling party identification, both, or neither)

•Number of seconds delay between the time the call comes into the original called party and the notification to the rest of the call pickup group members

You can configure the type of audio notification that is provided when a phone is idle or in use in the Directory Number Configuration window.

Cisco Product Security Overview

Cisco provides a free online Security Vulnerability Policy portal at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

From this site, you will find information about how to:

•Report security vulnerabilities in Cisco products.

•Obtain assistance with security incidents that involve Cisco products.

•Register to receive security information from Cisco.

A current list of security advisories, security notices, and security responses for Cisco products is available at this URL:

http://www.cisco.com/go/psirt

To see security advisories, security notices, and security responses as they are updated in real time, you can subscribe to the Product Security Incident Response Team Really Simple Syndication (PSIRT RSS) feed. Information about how to subscribe to the PSIRT RSS feed is found at this URL:

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 have identified a vulnerability in a Cisco product, contact PSIRT:

•For Emergencies only — security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

•For Nonemergencies — psirt@cisco.com

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

•1 877 228-7302

•1 408 525-6532

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to encrypt any sensitive information that you send to Cisco. PSIRT can work with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT at the aforementioned e-mail addresses or phone numbers before sending any sensitive material to find other means of encrypting the data.

Obtaining Technical Assistance

Cisco Technical Support provides 24-hour-a-day award-winning technical assistance. The Cisco Technical Support & Documentation website on Cisco.com features extensive online support resources. In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Cisco Technical Support & Documentation Website

The Cisco Technical Support & Documentation 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, at this URL:

http://www.cisco.com/techsupport

Access to all tools on the Cisco Technical Support & Documentation 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 & Documentation 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 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 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)—An existing 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 operations 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 the network is impaired, while 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.
