Help droid makes spontaneous calls

[dandelve]

My Motorola Droid will occasionally make phone calls after I've turned the machine off. I've observed the machine to restart and make a call, usually to a number prior to the topmost number on the call log. Any help on this?

I have had this happen to a couple numbers when phone is off. I do have a blue tooth and I do use the call log often, so perhaps it is related to one of those two as surmised herein. I have motorola Droid 2.2.1. I put the phone in sleep mode, but it spontaneously calls out. Once i thought it was because I may have hit a button on my blue tooth devise.
