Just so you know, I live in the 307 area code and I get these calls too. All they do is set up a VOIP account and state they, or fill in the form saying they are from Wyoming, when they could be anywhere in the US or overseas, like eastern Europe, Kenya or Bumphuck, Egypt. I get calls from all area codes and toll numbers. The Do Not Call registry is basically ineffective because it does not prosecute these people.
