There are two ways to disable the call channels:• Courtesy stop the channels (preferred method).After you courtesy stop call channels, CallPilot waits until the channelsare no longer active before disabling them, instead of suddenlyterminating active calls.• Stop the channels.When you stop channels, you suddenly disable them and terminateall active calls.The Maintenance screenUse the Maintenance screen in CallPilot Manager to do the following:• Obtain general information about components.• View component states.• Start and stop components.• Run integrated diagnostic tests.• View the results of the last diagnostic test run against a component.What the Maintenance screen providesThe Maintenance screen identifies the server platform and switchconnectivity type.
