Configuring CAPF on Cisco Unified Communications Manager
The Certificate Authority Proxy Function (CAPF) process allows supported devices, such as
Cisco Unified Communications Manager, to request LSC certificates from Cisco Unified IP Phones. The
CAPF utility generates a key pair and certificate that are specific for CAPF, and the utility copies this
certificate to all Cisco Unified Communications Manager servers in the cluster.
For complete instructions on configuring CAPF in Cisco Unified Communications Manager, see the
