What it does
A box that sits between a home phone and the wall jack and blocks robocalls and scam numbers.
How it can be used at home
An older adult who still uses a landline presses one button to block a scam caller for good, and known nuisance numbers never ring through.
Notes and limits
For landlines only. Comes with 5,000 known nuisance numbers loaded and room to block 1,500 more, per the maker's US store. No monthly fees from the maker. Caller ID must be turned on for your line by your phone company for it to work, per the maker's FAQ.
