i get these calls at random sometimes there will be music playing, other times just dead air. ive quit answering and put them on my reject list. I just thought it was strange. its not a normal telemarketer call. it returns to techhair out of rogers, arkansas as a cingular wireless customer. I have also given the number to a local detective friend of mine but i'm sure he has more important stuff to do and there were no threats of violence.
