LG VX-8600 / AX-8600

Hi, just picked up an 8600 this week. I’m hoping to find assistance for a couple things. First, is it possible to disable the little “squawk” that occurs directly following a missed call without activating the vibrate mode? Second, I’m looking for a ringtone with two basic characteristics. A tone that rings just once and does not repeat. Something like a simple couple beeps or chime, that sounds just once. Does anyone know where I can find a tone like that?

Thanks for your time.
