The last batch of applicants who have completed all three stages of the selection process haven't heard their results yet. I would think it will be several months before more recent applicants will hear about their applications because the current batch will probably fill the next two or three courses. There's not much sense in choosing cadets a year in advance.
As for the phone number to call, it is at the bottom of the FAQ, which itself probably has a clue or two about how you will be notified of the next steps.
