This number called our business today at 1444 hours. As it wasn't even close to being familiar and the caller ID said "Name Unknown", I figured it was a spammer or scam artist. So I picked up the phone but said nothing. No one said anything on the other end and the call disconnected after a moment, which makes me think it was either an idiot-message waiting for a voice or a system waiting for a voice to transfer me to the next available scam artist.
