I have a HTC WildFire (android 2.1) phone. I want to disable the notifications for the calls I knowingly decline. I still want to get the notification for the calls I miss. Does anyone know any setting/app to do this?
Try pressing the back button when you get an incoming call - that usually makes the caller continue listening to a ringing tone but the ringing on your phone stops.
Pressing the reject / call end button will make the ringing stop as well as cut the call for the caller.
If you'd rather stop the ringing / vibration but still want to answer the call after a few seconds (like walking out of a noisy room etc.), press any volume key on the side.
