Chapter 1 An Overview of the Cisco Unified IP Phone Understanding Security Features for Cisco Unified IP Phones 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. Table 1-2 shows where you can find additional information about security in this and other documents.
