Enabling Services Required for Security

When enabling security in your Cisco CallManager cluster, you have to activate these services:

• Cisco CTL Provider This service has to be activated on all Cisco CallManager servers and Cisco TFTP servers of your cluster.
• Cisco Certificate Authority Proxy Function This service has to be activated on the publisher server.

Activate Cisco CallManager services from the Cisco CallManager Serviceability Service Activation window, shown in Figure 27-1.
