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, you can familiarize yourself with Cisco Unified IP Phone documentation. Make
sure to visit the Cisco Unified IP Phone website:
http://www.cisco.com/en/US/products/hw/phones/ps379/tsd_products_support_series_home.html
From this site, you can access various user guides, including wallet cards.
In addition to providing users with documentation, it is important to inform them about available
Cisco Unified IP Phone features—including features specific to your company or network—and about
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 C, “Providing Information to Users Via a Website.”
Understanding Security Features for Cisco Unified IP Phones
Implementing security in the Cisco Unified CM system prevents identity theft of the phone and
Cisco Unified CM 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.
