If the participant is calling from a phone number that has Caller ID blocked, then Mobile Controller application will display number withheld or unknown. In cases where the Caller ID is not blocked, then Mobile Controller tries to match the Caller ID to a name either in your smartphone’s address book or a list of phone numbers belonging to colleagues in your company. If no name is found, a location is displayed.
