Abstract
A telephone is controlled using an external contact closure. The telephone includes a contact closure connector. The contact closure connector includes a first wire contact and a second wire contact. Control logic is connected to the first wire contact and the second wire contact. The control logic detects a change in electrical connection between the first wire contact and the second wire contact. Alternatively, the control logic detects a change in electrical connection between multiple pairs of wire contacts. In response to the change in electrical connection, the control logic issues a command to a processor connected to the control logic. The processor, upon receipt of the command issued by the control logic, implements a predetermined telephone function or set of functions.
