The last time I had a landline was 16 years ago when my wife briefly had a home office. Her employer required the landline as part of the home office setup (they paid for it).

We got spammed by robocallers every 5-10 minutes all day long and half the night. It was so bad that my wife never knew when a work call was coming in and had to let every call go to voicemail.

We didn’t unplug the phone just turned the answering machine to silent. We still got calls on a supposedly disconnected number.
