Caller ID came up "Michael Jenkins".  No message.  Blocked caller #518 (two Panasonics +  20 ATT IDs), idiot call #1063 (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 thrice caller ID indicated that I received a call from IT!

I have kept all of these numbers on a spreadsheet with dates and number of calls.  I will have to recycle the older IDs that only called once since the blocking systems will shortly be out of capacity.
