I purchased the CPR CallBlocker that was recommended by Jerryc41 on this site. Yes, it does cost $99. Yes, it does block the calls. It comes with 5000 known scam phone numbers. It blocks unknown, private and any numbers you want to add (up to an additional 1500 numbers). I have only added 37 numbers and I haven't had any scammers for over two weeks. Unfortunately, the credit card people tend to use many different numbers, 35 of the 37 numbers. But once you add the number, they don't get through. You do have the opportunity to answer (one ring) a "private" number if you want. I recently called a customer service number of a pharmaceutical company. The dummies called back on a private number. The CallBlocker rang once, then terminated. They called right back and I was able to answer. I explained they should change their ways and show who they are on caller ID. They said they didn't know why some people never answered.

This product is worth the money in just peace of mind. I hate those scammers. When you get a Toll Free number, or other, that you don't want, just hit #2. Their ID number is added to the list and they are immediately disconnected. BYE BYE scammers. You do have to answer the phone at least one more time until the numbers are added to the list. Just keep this product in mind in the future. The phone companies are making too much money from these people to be helpful. The "Do Not Call" lists don't work. I no longer have to deal with the phone ringing by bad guys.
