In the call monitoring section of the toolbar area, click settings. For information on the toolbar, see Overview of Real Time.
Call Monitoring Settings appears.
In Supervisor line number type the phone number on which you will listen to calls.
Click Save. The alert icon flashes and the list of alerts is updated.
If you have provided a valid number, a success alert appears. If you have provided a string containing characters other than numbers, an error message appears.
When you click to supervise a call, you will receive a call on this number. For information about supervising calls, see Supervising a call.
