Caller ID shows Fair Processing, a well known merchant processing scammer who has hidden fees, charges excessive rates and holds back a large amount of your funds for future charge-backs. These scammers also call from other numbers around the country such as 971-320-1051, 623-208-5574, 207-618-6061, 207-209-2580 and 574-575-4227.
BTW, Panasonic makes some good call blocking cordless phone sets, such as the KX-TG454 SK or KX-TG465 SK which both block up to 250 phone numbers. The Ooma phone system blocks 254 phone numbers and the T-Lock Call Blocker, which connects to your phone line, blocks 1500 phone numbers. You should check them out on eBay or Amazon if you want to block telemarketing calls. Hope this helps.
