To my knowledge you have to be rooted or use a third party App for this. The Droid1 uses flashing LEDS to notify you of a missed call, text message, email. The top right hand corner of your device next to the speaker has an LED light that will flash until you open the notification. Not as good as a beep or an audible notification but its all it came with as far as I know. Hope this helps and welcome to the forums!
