Delaying Incoming Calls Android

Question

A pop up appears in each android cell phone when a call is to be received and then the user accepts or reject the call from on that page . I am looking for a code in android which can delay the time of that pop up . For example when a call is received on the cell phone that pop up waits for 2 to 3 seconds before appearing on screen .
