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 on the
Cisco
Unified IP Phone web site:
http://www.cisco.com/en/US/products/ps10326/tsd_products_support_series_home.html
From this site, you can view various user documentation.
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 6901 and 6911 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.
