Caller ID came up "Green Energy". No message. Blocked caller #633 (two Panasonics +  20 ATT IDs), idiot call #1323 (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 four times the caller ID indicated that I received a call from IT!

I have received IRS scam call voice messages from four different telephone numbers threatening arrest.

All phone numbers are kept on a spreadsheet with dates and number of calls.  Since both blocking systems are full, I have been recycling the older numbers that only called once or twice.
