A method and system are provided for processing an incoming call and providing an interactive voice response unit with application flow control and call arrival and departure control. The system includes a call router including rules for handling call arrival and call departure and an interactive voice response unit. The interactive voice response unit includes a state and event table for operation as a state machine for intermediate processing between call arrival and call departure. An additional external resource is provided for updating the state and event table in order to control interactive voice response application flow. The method includes processing call arrival at the call router, performing intermediate processing with the state machine at the interactive voice response unit, and handling call departure procedures at the call router. The method additionally includes updating the state and event tables and providing application flow control using an external resource.
