Phone made a call on it's own

[bullittmustang]

My phone was on the charger next to the bed last night. During the night it made a call on it's own without being touched. It was the last person I had called. I woke up when I heard the other persons voice-mail coming through. I've never had this happen. Any ideas? I noticed it did do an apps edge update during the night. Also, I do not have s voice turned on.

Thanks
