Caller ID came up "FLEET OPERATION".  No message.  Blocked caller #474 (two Panasonics), idiot call #965 (not including obvious mis-dials) since 5/2/13.  Caller ID "1" (100-000-0000) has called 70 times, including 12 in one day, 6 on another.  I also had to block my own scammed number as twice caller ID indicated that I received a call from IT!
