droid 2 missed notifications

[ezecho]

I had the droid 2 for about 2 weeks and have figured out most things on it but one thing I can not figure out is how to set the notifciations of a missed call or voice mail. When a called is missed it does play the notification one time example it a short tune, after that it never give any more notifications for that missed call. On other phones I had in the past I could set the notification to alert me every 2 minutes 5 minutes ect. But I sure cannot find any setting that will allow me to do this. Maybe the droide 2 may not do this?

Thanks in advance,
