Received a call from this number at 12:45 a.m. March 25/12.  I am on Vancouver Island.  Called ID says "unavailable."  Good thing I turn my ringer off when I go to bed!  Called them back to see what it was - got a recording saying number has been disconnected.  Obviously this is a proxy-dial or whatever they call it.  My phone has a call block feature - greatest thing ever invented - so these idiots are not getting through again.
