Who called from 4078154151

I'm on a do not call list.  From reading the internet, this is a scam.

Just received a call from this number on my mobile phone and on a do not call list.  They left no message.  I just blocked the number.

This number called and left a 10 second voicemail that was just white noise in the background. Why call my number if you don't even know me or can't even leave a proper message?

I also called back and received the same message.  I am on the no call list.  They called my cell, so i blocked the caller on my phone

Travel scam.  Block them (or report them if you're feeling frisky and don't mind pointless exercises with government organizations).
