Preface
Overview
Cisco Unified Wireless IP Phone 7921G Administration Guide provides the information you need to understand, install, configure, and manage the Cisco Unified Wireless IP Phone 7921G on your network. This guide is intended to be used to administer phones running with Cisco Unified CallManager Release 4.1 or later and Cisco Unified CallManager Release 5.0 and later.
Audience
Network engineers, system administrators, or telecom engineers should review this guide to learn the steps required to properly set up the Cisco Unified Wireless IP Phone 7921G on the wireless network.
The tasks described are considered to be administration-level tasks and are not intended for end-users of the phones. Many of the tasks involve configuring network settings and affect the phone's ability to function in the network.
Because of the close interaction between the Cisco Unified Wireless IP Phone 7921G and Cisco Unified CallManager, these tasks require familiarity with Cisco Unified CallManager.
Objectives
This guide provides the required steps to get the Cisco Unified Wireless IP Phone 7921G up and running on a wireless Voice-over-IP (VoIP) network. Because of the complexity of an IP telephony network, this guide does not provide complete and detailed information for procedures that you need to perform on the Cisco Unified CallManager application or other network devices.

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:
•
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.
•
In an emergency, you can also reach PSIRT by telephone:
•
•
Tip
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:
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 to find other means of encrypting the data before sending any sensitive material.

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 2447For 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.
