Chapter 1 An Overview of the Cisco Unified IP Phone

Understanding Security Features for Cisco Unified IP Phones

For more information about configuring features and viewing statistics from the phone, see Chapter 7, “Configuring Settings on the Cisco Unified IP Phone” and see Chapter 10, “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/ps10453/products_user_guide_list.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 secure (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 8961, 9951, and 9971 use the Phone security profile, which defines whether the device is nonsecure or secure. For information on applying the security profile to the phone, refer to the Cisco Unified Communications Manager Security Guide.

If you configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file will contain sensitive information. To ensure the privacy of a configuration file, you must configure it for encryption. For detailed information, refer to the “Configuring Encrypted Phone Configuration Files” chapter in Cisco Unified Communications Manager Security Guide.
