i'm getting calls from this number on both my home and cell phone and there is never anyone there. it's all dead air. if i don't pick up, there is never a message. it's pretty scary to get the call on my home number, immediately following by a call to my cell.
Got this call late in the afternoon and there was no one on the other end. My guess is that it is some sort of auto-dialing marketing service that checks whether/when someone answers your line so that they can steer telemarketing calls to you around the same time of day you answered.
