When you call the number back, a recording by an unidentified company says, Thank you for calling back. If you are not interested in receiving any future calls regarding our special promotions and would like to be placed on our Do Not Call list, please press 1 now. The recording repeats a couple of times, then hangs up on you. There is no way to talk to anyone. Obviously any company that answers their phone this way is a scammer! 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 personal phone numbers and thousands more on their community blacklist. The T-Lock Call Blocker, which connects to your phone line, blocks 1500 phone numbers. You should check them out on eBay or Amazon (or Google them) if you want to block telemarketing calls. Hope this helps.
Update; these scammers have been really busy lately and are also calling from 218-878-9698, 443-602-8127, 616-828-5965, 508-425-4617, and 620-842-9049 offering business loans.
