icanhandthemback and I explained why mesh systems do not work well in our house, even though we have one.
I prefer phone calls, but emergencies apart, I do not want them on my mobile when I am out of the house. I am neuro-diverse and find phone calls in distracting places, like shops, in the street etc, with the background of sound, movement and light variation make it difficult to hear what is being said.
On the other hand, at home, when I can sit in comfort, at my desk or in the living room, but usually in a room by myself, I thoroughly enjoy long phone calls with AC or friends. But holding mobile phones for any time is very uncomfortable, and I find the rounded more narrow shape of the landline/VOIP phone much better and it does no exacerbate the problems I have with my hands.
