Abstract: An apparatus for restricting telephone calls placed onto a telephone line by a telephone set, wherein an off-hook condition begins operation of the apparatus and energizes a control circuit which provides a condition in which a call can be placed onto the telephone line. A disabling circuit responds to the control circuit and establishes a disabling condition on the telephone line which defeats a telephone call when it is of a restricted type. In one embodiment, the off-hook condition starts a time delay at the end of which a predetermined frequency is placed onto the line. The occurrence of this frequency signal onto the telephone line disconnects all long distance telephone calls beyond a specified local zone. In a second embodiment, each number entered onto the telephone line is counted, and when a predetermined count is reached the disabling circuit is operated to prevent further calling.
