Default Ringers

This may seem like a silly question and I don't know if its all android phones or just the Sprint HTC Hero but is there any way to change the rings so they have a pause in between like normal phone ringers rather than a constant ring until answered?

 

Yea I figured one could be made. So far all the default ones I've chosen are constant ringing. I'm just used to other cell phones I guess with a "ring"..pause..."ring"..etc. Not a big deal though.
