Only negative comment would be that it seems if more than one phone call comes in at same time the second call gets ringing does not go to voicemail

I wish that i could just input and block a number that rang earlier rather than having to return the call and get a dial tone before it will block that number that was missed when the phone initially rang

As the jack i was using was for a two line phone i had to purchase a line spliter which seperated the two incoming phone line into seperate lines each phone number on a different rj11 modular jack

Since the phone line where the call blocker is connected is in the kitchen and there is a two line phone on our lower level we can hear the phone ring on the lower level

There is a delay in the klitchen phone ringing as the device compares the incoming phone to those stored
