Call drop is a basic operation supported for all call types. Both the caller and the called user can end the call. For example, the user can drop the call in one of the following cases:

• If the caller needs to fill out the post-call survey.

• If the call is malicious.

• If the user needs to evacuate in the event of emergencies.

After one of the parties presses the corresponding key or softkey on the endpoint, the contact center ends the call. After the call ends, Routing Core Server sends a report to Call Management System.

For more information about ending calls, see your endpoint documentation.
