I got a call from this number and it seemed as though it was a pocket dial because there was a voicemail but no message. Just voices in the background. I sent a text to it asking to see if I knew them and what they wanted because I lost all my contacts a few months back, and apparently it couldn't go through, After reading through the previous comments on here though, I'm assuming now that it was just some nut who didn't know what to do once they hit my voicemail and couldn't make up their mind whether to leave a message or hang up. Either way, it left me confused and slightly annoyed. I hate it when people have my number who have no business having it...
