At the moment when I miss a call, there's only visual sign of it. It's not very useful when I have my N900 in my pocket. It'd be very handy if there was a sound (beep) notification for it as well. It might play every 5 minutes for example. Actually the best solution would be if a phone user could set time intervals, sound and behaviour for specific event (call, text, mail).
