Deafness is a spectrum. If you've got sufficient hearing - and pick the right phone - it can work out. I usually have a second party on the call who can explain anything I mishear via instant messaging.

I've experimented with a wide variety of techincal solutions over the years, and I've learnt that the often-compressed bandwidth of cell phones is bad -- I avoid calls using cell phones like the plague these days.

Since I work remotely, in a private office, I can get away with using a really high quality speaker phone. With hearing aids as they are today, including digital processing and noise discrimination, it works OK.
