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/univercd/cc/td/doc/product/voice/c_ipphon/ip_clmgr/engl
ish/index.htm.
From this site, you can view and order various user guides, including wallet cards.
For complete ordering information, see the
on page xiv.
In addition to providing users with documentation, it is important to inform them
of available Cisco Unified IP Phone features—including features 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
Implementing security in the Cisco Unified CallManager system prevents identity
theft of the phone and Cisco Unified CallManager server, prevents data
tampering, and prevents call signaling and media stream tampering.
To alleviate these threats, the Cisco Unified Communications 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,
encrypts media streams between Cisco Unified IP phones, and encrypts call
signaling between Cisco Unified CallManager and the phones.
Table 1-2 shows where you can find additional information about security in this
and other documents.
