iOS - Detecting calls, cancel them an then do something -

is possible 1 make app listens call events, if number equal something, cancel call , other stuff?

edit: people asking why wanna when it's such simple question that, i'm having difficulty in understanding negative feedback. question states, wanted capture call events , if number dialed equal specific number, call wouldn't proceed , else instead. question not broad (unless have place whole requirements engineering of app) neither complicated one. simple question of "is possible in ios?".
