Understanding Control Center

Cisco CallManager Serviceability provides a web-based Control Center tool used to view status and to start and stop Cisco CallManager services for a particular server or all servers in the cluster.

Starting and stopping a Cisco CallManager service causes all Cisco IP phones and gateways currently registered to that Cisco CallManager service to fail over to their secondary Cisco CallManager service. Devices and phones need to restart only if they cannot register with another Cisco CallManager service. Starting and stopping a Cisco CallManager service causes other installed applications (such as Conference Bridge or Cisco Messaging Interface) that are homed to that Cisco CallManager to start and stop as well.

---

Caution Stopping a Cisco CallManager service also stops call processing for all devices controlled by that service. When a Cisco CallManager service is stopped, calls from an IP phone to another IP phone will stay up; calls in progress from an IP phone to a Media Gateway Control Protocol (MGCP) gateway will also stay up, and other types of calls will be dropped.
