Cisco 7941G Administration Guide

DescriptionFeature
Uses SRTP to ensure that the media streams between supported devices proves
secure and that only the intended device receives and reads the data. Includes
creating a media master key pair for the devices, delivering the keys to the
devices, and securing the delivery of the keys while the keys are in transport.
Media encryption
Ensures that all SCCP and SIP signaling messages that are sent between the
device and the Cisco Unified Communications Manager server are encrypted.
Signaling encryption
Implements parts of the certificate generation procedure that are too
processing-intensive for the phone, and interacts with the phone for key
generation and certificate installation. The CAPF can be configured to request
certificates from customer-specified certificate authorities on behalf of the
phone, or it can be configured to generate certificates locally.
CAPF (Certificate Authority
Proxy Function)
Defines whether the phone is nonsecure, authenticated, encrypted, or protected.Security profiles
