Configuring Network Parameters Using the Cisco Unified IP Phone
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 Chapter 4,
“Configuring Settings on the Cisco Unified IP Phone” and see Chapter 7, “Viewing Model Information,
Status, and Statistics on the Cisco Unified IP Phone.”
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 Phones 7962G, 7942G, 7961G, 7961G-GE, 7941G, and 7941G-GE 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, refer to the Cisco Unified Communications
Manager Security Guide.
