device for blocking calls? [View all]

[lululu]

Not sure this is the right place to ask this -

I am going nuts with telemarketer calls from the scam people who ignore the do not call list. The only good thing is that so far they tend to reuse spoofed numbers. I get easily ten calls a week and it seems to be increasing.

My phone service isn't compatible with the Nomorobo thing and Verizon no longer offers call block, so I have to buy some gizmo.

The problem is that when I read about them they either have lots of complaints on amazon reviews about not working, refusing legitimate calls, etc. or the ones that work have incredibly complex directions.

I bought a Panasonic phone that has a call block feature, but the setup is so complex I think it will interfere with my other phones, answering machine, etc.

Does anyone know of a simple device that will just block the list of numbers I give it and not do anything else?

Thanks.
