Phone compatibility - Need for Senior

[Jer73]

Hi folks. I am looking for a super simple phone for my mother...91 years old with a touch of dementia. I found a big button phone with 1 touch - each button has a photo of a family member. Push the button and it dials the number. I cannot find any compatibility list. My question is simple...will any touch tone phone work with Ooma? If not, can someone please direct me to a phone that would suit my needs. Help is truly appreciated.

Any touch-tone phone that uses a modular plug will work with Ooma.

Make sure that it actually generates touchtones. There are push button phones available that pulse dial when a button is pushed. The Telo does not support pulse dialing.

Thank you for the prompt responses!
