Understanding Security Features for
Cisco
Unified IP Phones
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 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, 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.
