I have also been getting these calls, all from the 940 area code, fax tone on my business 866-***-**** fax/phone line.  The last 2 numbers were both registered to the same guy, I'm guessing this one is too.

I know right, I've been getting these calls too. Someone should put a stop to this. Is not this considered phone harrassment?

I've been receiving these "fax" calls more and more. I've got the number on the "Do Not Call" list, but these calls don't stop. I'm trying to run a business, and tend to answer all calls just in case it is a prospect or customer, but this is getting ridiculous. I thought this type of stuff was illegal.
