just wondering the point of it all - calls - silence - disconnects
checking the line to see if active?
recording your voice when you answer?
wish telstra /optus etc read this site and were more active to block scammers
surely cant be too difficult if they really cared about their customers

Left my answering machine on for any number that I don't recognise. Strange, nobody leaves a message. This scammer hops between two numbers - (02) 8310 7913 and (03) 8318 4905.

Called and left a voice message singing, "you know what to do with that big fat butt."
