800-969-3666

I called this number back   "Gateway EDI" and began to say that someone from their office called my personal cell phone.....and then they hung up.  Obviously an illegal call as I am on a national no call list.  
I will report them to the proper authorities.

Gateway is working with a large medical billing group.  They were provided phone numbers to contact and it is obvious they are working from an old list. Legit company, but if you are not a medical provider, it was probably simply a bad number on their list.  I know they are doing a huge campaign with Cerner Corporation.
