A device and method for controlling the use of a telephone make a
determination as to whether a telephone call may proceed. The
determination may be based upon a time reference, such as a total amount
of time that a call may proceed or an interval of time when a call is not
permitted. The determination may alternatively be based upon whether the
user is authorized by entry of a personal identification number prior to
placing the phone call. Various other considerations may be accounted for
including whether the call is to a particular telephone number and/or
whether the call is long distance. If the call may not proceed, then the
circuit between a telephone and the telephone network is obstructed to
terminate the telephone call.
