Configuring Network Parameters Using the Cisco Unified IP Phones
You can configure parameters such as DHCP, TFTP, and IP settings on the phone itself. You can also
obtain statistics about a current call or firmware versions on the phone.
For more information about configuring features and viewing statistics from the phone, see Configuring
Settings on the Cisco Unified IP Phones and Viewing Model Information, Status, and Statistics on the
Cisco Unified IP Phones.
Providing Users with Feature Information
If you are a system administrator, you are likely the primary source of information for Cisco Unified IP
Phone users in your network or company. To ensure that you distribute the most current feature and
procedural information, familiarize yourself with Cisco
Unified IP Phone documentation. Make sure to
visit the Cisco
Unified IP Phone web site:
http://www.cisco.com/en/US/products/hw/phones/ps379/tsd_products_support_series_home.html
From this site, you can view various user guides.
In addition to providing documentation, it is important to inform users of available Cisco Unified IP
Phone features—including those specific to your company or network—and of how to access and
customize those features, if appropriate.
For a summary of some of the key information that phone users need their system administrators to
provide, see
Appendix A, Providing Information to Users Via a Website.
Understanding Security Features for Cisco Unified IP Phones
Implementing security in the Cisco Unified Communications Manager system prevents identity theft of
the phone and Cisco
Unified Communications Manager server, prevents data tampering, and prevents
call signaling and media stream tampering.
To alleviate these threats, the Cisco IP telephony network establishes and maintains authenticated and
encrypted communication streams between a phone and the server, digitally signs files before they are
transferred to a phone, and encrypts media streams and call signaling between Cisco
Unified IP Phones.
The Cisco Unified IP Phone 7962G and 7942G use the Phone security profile, which defines whether
the device is nonsecure, authenticated, or encrypted. For information on applying the security profile to
the phone, see Cisco Unified Communications Manager Security Guide.
If you configure security-related settings in Cisco Unified Communications Manager Administration,
the phone configuration file contains sensitive information. To ensure the privacy of a configuration file,
you must configure it for encryption. For detailed information, see
Configuring Encrypted Phone
Configuration Files in Cisco Unified Communications Manager Security Guide.
Table 1-3 shows where you can find additional information about security in this and other documents.
