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.
