Guidelines for Using Accessories and the Phone
Follow these guidelines when using accessories and your Cisco Unified Wireless IP Phone 7920:
•Use only chargers, batteries, and accessories that are approved by the Cisco Unified Wireless IP Phone 7920 manufacturer.
•Do not adhere a clip to the back of the phone or insert a clip between the phone and battery cover because it can damage the battery.
•Use a protective cover case to shield the phone from moisture, dust, hair, grease, and other contaminants that might get on your hands. For example, in Healthcare environments, where phones must be cleaned with sterilizing wipes, you must use a protective cover case to prevent moisture damage to the phone.
•Use a protective cover case in environments where the phone might be bumped or dropped, such as manufacturing or warehouse environments.
•When disconnecting the power cord of any accessory, grasp and pull the plug. Do not pull the cord.
•Clean the phone only with a soft dry cloth. Do not use moist wipes or cleaning powders that might damage the phone.
Note Using unapproved accessories, not protecting the phone from moisture, contaminants, and hard impacts can invalidate the one-year hardware warranty on the phone.

Cisco Product Security Overview
Cisco provides a free online Security Vulnerability Policy portal at this URL:
From this site, you will find information about how to do the following:
•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:

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 — firstname.lastname@example.org
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 — email@example.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 encryption key 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:
The link on this page has the current PGP key ID in use.
If you do not have or use PGP, contact PSIRT to find other means of encrypting the data before sending any sensitive material.

Modifications to or updates about Cisco products are announced in Cisco Product Alerts and Cisco Field Notices. You can receive Cisco Product Alerts and Cisco Field Notices by using the Product Alert Tool on Cisco.com.

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:
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
For a complete list of Cisco TAC contacts, go to this URL:
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.
