The only real solution is to get a phone service (in my case a VOIP / www.itpvoip.com) that allows blocking of individual numbers. I got one fax call from this clown and knew it was junk. 30 seconds later I have programmed his number and he will get a "not in service" message while I hear *nothing*.
Junk calls that get through to me have dropped by 95%. Blessed peace.
Get numerous phone calls from them daily! Probably wasn't a good idea, but I did put my number in on their website to get them to stop calling. It's getting old ... real old!
