I picked up the phone, said nothing for a few seconds and "it" waited.  Then I mumbled something into the receiver and it hung up on me.  

We are a business and I cannot refrain from answering the phone.  Considering our location, we have a great deal of people who move here and retain their numbers from previous states.  

I called it back, just to see if I could wrangle someone on the line, but as was stated by a previous poster, it is a recorded message giving you the option to press a number to be placed on their DNC list.  

They [***] suck and have no life. i wish the FBI would do something about these people and those scumbags calling from india with a "10,000$ federal grant" [***] [***].

I'm on the do not call list besides its a robot

They tried to call me too. I offered them my big headed [***] and they hung up.

It's funny, I received the pre-recorded, fake, call from Patricia yesterday where the recording sounds all excited, asks you how you are and then pauses to let you respond before going into it's pre-recorded sales pitch.  However, today, when "Patricia" called back... with the same excitement, same how are you doing today question, my response was "Oh, it's that recorded [***] again."  However, I guess she was actually following up as it suddenly said "What? Wait, I'm a real person." Then, I guess because I was laughing too much, they simply hung up on me.  Maybe that'll get me off their list.
