I got a call from this number and there was no response when I answered. I have tried calling the number back but it has been busy for about a half an hour. I registered on the do not call registry a long time ago but apparently this number doesn't care.
I've received two calls, and it is a recording - exactly the same thing each time. Calls at any hour of day or night too. When it connects you hear a little static or something. After you say hello, it says hello then a pause and another hello. Then it disconnects. I haven't called them back, because there are lots of negative comments about this number online. If you can block it then I would recommend doing so.
