Caller ID came up "COMPLAINT SYSTM". No message.  783 Blocked calls so far (two Panasonics +  20 ATT IDs), idiot call #1883 (not including apparent mis-dials and obvious political calls) 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 scam IRS calls from four different numbers threatening prosecution.

All numbers have been kept on a spreadsheet with dates and number of calls.  Since both blocking systems are full, I have been recycling the older dated numbers that only called once or twice.  I have also added No Mo[re] Robo to my blocking arsenal.
