Calls and leaves no message.

I just got a call which I have added to my block list.  I will now get no ring but will get a list of blocked calls on my phone. See below.

I have the Panasonic cordless telephone  Model kx-tg6842b (2 handsets)
You can block 250 numbers plus kill the one ring that existed on earlier models that only allowed 30 blocked numbers.

The one handset model sells for $70 at Amazon.
