Received a call from this number. When answered no one said anything. I called the number back and got recording "all circuits are busy call back later".

I get the  same thing. But  to  add insult to injury, they  called  me  three times in  one  day and hung up after I said Hello. all  phones are registered with  DO Not Call and  yet  it  does not  stop them.

I didn't answer. They left no message.
