Do you want the sound to stop when you clear the notification?
Yes. I am on call daily for work, and when they call, I need to call them back in 20 minutes. But if my phone is on ring, and I dont hear it, I never know to go look to see if I have a missed call.
There is an app called "Missed Call" that will do this for you......
Ive heard of that app, but also heard it doesnt work well on 2.2 Android, and the development on the app seems to have stopped
