I have ACR activated on my home phone but I keep getting calls with people trying to send faxes. I just got this phone number about 8 months ago when I moved into a new house and from what I can find on Internet, my number was the fax number of a local company who has since moved their business. These calls don't have a name or number on the caller ID. I believe I read that ACR only works in your local calling area. What can I do to stop these calls from coming through? Yesterday I received calls about every minute for quite a long time. It's really annoying.
