Here’s what we got for my dad.

There are three big numbered buttons that can be preprogrammed, so we programmed them for my brothers and me in birth order, so easy to remember. That big button on the lower right is the speakerphone so when he gets a call all he has to do is press that button to answer. To call any of the three of us using the big numbers, he just presses the speaker button, then the big number. He has shaky hands so not having to hold the receiver was important. He quite liked the phone, but have to say, since he got comfortable with his echo he never uses the phone anymore, just orders echo to call people. Movement is pretty difficult so voice control works better. Family knows that he usually won’t make the effort anymore to answer our calls, he’ll just wait until the phone quits ringing (it announces who the call is from), then tell the echo to call whomever was trying to reach him.
