Received call at 12:30AM, Oct 24, 2009. Caller did not leave message. I called the number and got voice mail that did not indicate the owner of the number. I left no message but made sure I used up a fair amount of his voice message storage. May do it a few more time before the weekend is over.
Similar experience, called at 1:49 a.m. no one was on the other end. The common thread here is the calls in the middle of the night. I am very curious to figure out who this is..
