Cisco 7925G Administration Guide

DescriptionFeature
Implements parts of the certificate generation procedure that are too
processing-intensive for the phone, and it 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, or encrypted. See
Security Profiles, on page 17 for more information.

Security Profiles
A security profile defines whether the phone is nonsecure, authenticated, encrypted, or protected. Every Cisco
Unified IP Phone that is supported by Cisco Unified Communications Manager Administration has a security
profile. For information about configuring the security profile and applying the profile to the phone, see Cisco
Unified Communications Manager Security Guide.
For Cisco Unified Wireless IP Phones using Cisco Unified CallManager 4.3 and later, security is configured
on each phone. For more information about configuring security, see Cisco Unified CallManager Security
Guide at http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html.
