call an hang up, or answered no one on the phone. call back number not in service. no way to identify caller or were there calling from. shut them down.
They called at 7:11 PM (1/21/2013), one of the latest telemarketer calls I've had. I didn't pick-up, and they let it ring until the answering machine 'picked-up', when they hung-up.
Ditto on 3/7/2014. Time to add another block. I wonder if some of these hang ups are kids playing with phones? Not that spammers are innocent - just thinkin....
