Yep!  Same here - just a hang up.  I am guessing it is DTE trying to install a smart meter

Calls multiple times per day. I've blocked this number and several with the same caller ID. Calls keep coming. No message left. Called ID says DETROITZN4 MI

Called me and left no message.  Blocked the number.

I've turned the answering machine off. These ignorant calls are all we every receive on our land line anymore. Anyone who wants to speak to us just calls us on our cell numbers. Really don't these people have anything constructive to do? I think sooner or later they would want to get out and make an honest living. Why wont the FCC do anything about them? I have registered on the "Do not call list", but for what reason. The FCC is just as bad, they dont do a thing to stop them, I simply get no response what so ever!!

Called number back was a recording of 98Live web radio telling me I won for being caller 15. Called back again and it said survey now closed.
