Starting and Stopping Cisco CallManager

There are three methods for starting and stopping Cisco CallManager:

Using the Control Center in Cisco CallManager Administration. See the "Using the Control Center" section.
Using the Windows Control Panel for Services. See the "Using Windows Services" section.
Using the Reset button in Cisco CallManager Administration. See the "Using the Cisco CallManager Reset Button" section.

Caution Stopping Cisco CallManager also stops call processing for all devices controlled by that Cisco CallManager. If you have not configured a backup Cisco CallManager for those devices, any calls in progress on those devices are dropped. See the "Redundancy" section.
