•Starting a Service

Cisco CallManager Serviceability provides a web-based Control Center tool that is used to view status and to start and stop Cisco CallManager services for a particular server in a 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.

---

Note If you are upgrading Cisco CallManager, those services that were already started on your system will start after the upgrade.

---

---

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 get dropped.

Note You can activate or deactivate services from the Service Activation web pages. To access Service Activation, click the link from the Control Center web page. Refer to Chapter 10, "Service Activation" for more information about Service Activation.
