This is a weird one. It only showed the area code and number, but there is usually the number one in front of the area code!
Hmm...not with this one though. Very strange also cause the phone rang 3.5 times (I have my ringer set for 3 rings), then the phone started to ring again as if I was getting a "new" call coming in but it turned out to be this same number calling again immediately following their first call! It was almost like it never disconnected from the first call coming in. I didn't answer either time.
