I just got a call at home from this number, answered, and no response. Just what sounded like a faint clicking. I was just wondering if you're from anywhere near the Lake Ray Hubbard area. I was thinking if they're all targeting the same area, perhaps it's a known "nuisance". ? Also, we tend to get a lot of these unknown name or out of state numbers at home, which is another reason why I think it could be a known nuisance. That just started relatively recently.
