If you don't have, you should have, caller ID and voice mail. We also have a landline and if we don't recognize the number we don't answer. If they really want to talk to us or it's an important call (kids or grandkids or a tee time) they will leave a message and we will call back. The caller ID also shows up on the TV. Your phone should also have a switch to turn off your ringer so if you need a nap turn it off. We do that occasionaly since the number shows up on the TV. I have my phone through Brighthouse/Spectrum and they have call block which allows me to block calls by number. nomorerobo I believe, is an app for mobile phones, not land lines.
