Corrected entry: When Ed Rooney presses the phone button to take Ferris' call he says nothing but Ferris speaks right up to ask him to get his sister to get his homework assignments. How did Ferris know Rooney was on the phone?

Correction: Ferris would have been put on hold, so was most likely having to listen to music. When Rooney pressed the appropriate phone button, Ferris would be taken off hold - the music would have stopped, so Ferris would know that somebody was now listening - as he'd presumably asked to speak to Rooney, he simply assumed, correctly, that that was who he was speaking to.
