The present invention is a digital telephone control interface system that provides a programmable control to the keys of a digital feature telephone. The programmable control selectively masks the keys present on a telephone and prevents masked keys from being directly responded to by the telephone or routed to the telephone switching network. While the keys are masked, the programmable control can suppress, delay, modify or enhance the key events produced by the masked keys as directed by the application software being run by the programmable control.
