Can't answer calls

From time to time, usually if my phone has set overnight, it starts vibrating as if I have a call. The screen shows the spinning clock in the center and no caller ID pops up. I can't answer it. When it stops vibrating it pops up with a missed call from an unknown number.

I'm using the BBCrackman 113/114 hybrid, the default skin, and the application "Buzz Me." I'm on Verizon with a 9530.

I used the search and found nothing.

Mine would do that too but I called verizon and they sent me a new phone right away. Keep in mind that this would be my 3rd phone now. So far so good with this one. Good luck
