850-391-4399 called 1:57pm 13 Sept 2016. Robo call that sounds like a human. CID reads TALLAHASSEE FL.  It will say "Hello, Hello?"  If you answer, it will launch into its fund raising speech.  This one is the infamous Florida Troopers Association.

CID:V91717442800077. Left no message, so not important.

These [***] called me on a Sunday evening at 7:30!
My call blocker is full.  AT&T does this on purpose, they want the call usage money from these scammers.

Get away from landline service entirely. It's way too expensive and useless at combating scammers. Take a look at the many voip options, they are far cheaper, better at blocking scammers and give for free most of the features AT&T charges a premium for. I use voip.ms, but there are several good options.
