Simple solution that often works… get a digital recorder, call any fax number, record the computer trying to connect to you. When the scammers call you again, answer the phone and play the recording. Most computer calling programs are designed to delete fax machines from the call list. I keep a recorded fax by the phone all the time, great for getting rid of many pests working by phone.
