Call Blocker Upgrades…
This is the third call blocker I've bought, each with higher capacity in the newer model. Really nice that CPA sells the new models to existing customers at a discount. That's taking care of your customer base.

Almost no span calls.

Great so far. Blocking many numbers without programming.

I love having the CPR products. I recently upgraded from an original model because I blocked almost the limit of 2K calls. I like that this model is much easier to use and the optional extra blocking and preinstalled numbers is wonderful. I highly recommend this to anyone who has a landline and gets alot of annoying soliciting phone calls.

Returned it. Had asked a simple question on line and rather than an answer, they wanted a log in , etc.

As soon as my new V100k blocker arrived I installed it and waited for the result. Nothing happened for six days, and then at last my phone rang, and my first 'unwanted call arrived, and BINGO' it vanished with a quick press on the magic button. I now have 100,001 blocked numbers working, and two days later I had another success, so that was the proof I needed that the blocker really works! What a great product I now have, and what a boon to have a peaceful time. It also worked well on the #2 function with my multi setup of 3 extensions. I am so grateful for such a good product, and my neighbours are green with envy (until their purchases arrive).

Great for telemarketers but great for local calls to block them as received.
