Answered the call.... only silence

Called this number back.

Got a recorded message saying it was from an outfit called "Vacation Promotions."

Guess the do not call registry means nothing anymore.

I answered and the caller asked for (my 1st name as if to through me off I guess). I said that "he" wasn't here. The caller said the she would call at a better time. I the asked who was calling, to which there was no reply. Just silence, except for some background noise. Then she hung up.
  I have spent years straightening my financial past and everything else that I can think of that could haunt me, so I P/U this time only out of curiosity. Otherwise, when a caller id # comes in and leaves no message, I don't pick up.
