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 in the cluster.

Starting and stopping a Cisco CallManager service causes all Cisco IP Phones and gateways that are 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 that are 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.

Note You can activate or deactivate multiple services and choose default services to activate from the Service Activation tool in Cisco CallManager Serviceability. You can access the Service Activation web pages by clicking a link on the Control Center web pages. See the "Service Activation" chapter for more detailed information about Service Activation.

Stop or Start a Service

Use the Control Center tool to stop or start a service for a particular server in a cluster.

---

Caution Cisco recommends that you do not use Window Service Control Manager (SCM) to start and stop services for the Cisco CallManager because the services may not perform as expected. Use the Control Center to start and stop services.
