ABSTRACT:
A device for limiting unauthorized access to a telephone hand set. The device comprises a cabinet for receiving and holding a telephone hand set. The cabinet has an enclosed bottom, enclosed sides and an open top. A removable cover is received into the upper portion of the cabinet and has an open and a closed position. When in its closed position the cover seals the open top of the cabinet to enclose and limit access to the key pad of the telephone hand set while providing unlimited access to the receiver. When in its open position the cover provides unobstructed access to the telephone hand set. The cover allows for the activation of pre-determined keys on the key pad of the telephone hand set when the cover is in its closed position. A lock secures the cover in its closed position.
