Abstract

A method for minimum supervision of an offender required to report in to an electronic supervision system. The method includes pre-enrolling the offender in the electronic supervision system and assigning an authorized telephone number. A telephone call is placed by an individual from a telephone located at a remote location, the remote location telephone having an originating telephone number. The telephone call from the remote location is accepted and it is determined whether an ANI of the originating telephone number is available. If available, the ANI of the originating phone number is captured. An enrollee ID number assigned to the offender is entered. The originating telephone number is validated against the authorized telephone number assigned to the offender to verify the location of the remote telephone. It is determined whether a voice template is on file for the offender. The individual is prompted to respond to a plurality of user definable inquiries regarding the status of the offender. The identity of the individual placing the telephone call is verified using voice verification technology during the telephone call.
