It is so nice to have the quiet!
It is so nice to have the quiet associated with having a call blocker and it is a pure joy to manually block a number when it hasn't been blocked previously. It is somewhat confusing to figure out how to wire the call blocker to our particular landline. I found that the configuration that worked for our system was not the one I would have thought. If your system is not working properly, I suggest you go through all the possible wiring configuration until you find the one that works for your system.

Thank you for the great review! We're thrilled the CPR Call Blocker is giving you that peaceful quiet and the joy of manually blocking calls. Thanks for the helpful wiring tip - landline setups vary, so trying the different configurations (series or parallel) is spot-on advice. Our guides cover both to make it easier.
