Caller ID shows local caller.  I answered with a business name and they hung up.

Thank you soooooo very much for this post.  I got suspicious when he asked for my credit card number,I had a real funny feeling and told him I did not wish to lower my credit card rate and hung up.

I have researched online to purchase a call blocker device that you plug into your phone line. I am buying both the CPR call blocking model V 202 and the Sentry 2. Amazon reviews has great feed back from customers about them. What one lacks the other takes care of. Also Go to youtube and search that model number to see what it does. if you plug it in a certain way you won't be able to use your caller ID. But it's a simple fix or switching is very simple not complicated check it out. believe me I have no invested interest in this device at all. I just want to have peace and quiet like you no phone calls.

Your post reads like a veritable Hungarian goulash filled with gushing praise for something you don't own yet, but you are even telling everyone how easy it is to set up.  You have done this three times so far:
