I've received several calls from 425-363-9581 over the past couple of weeks. I have ignored them until tonight. When I picked up the phone there was no one at the other end. Then the phone call ended abruptly with a click. What a waste of time.
obviously computer controlled. no person started talking until about 10 sec after my voice mail message, then they called me by name. Added number to Ooma Blacklist.
