Disability Features?

We purchased a wireless Ring Video Doorbell for my dad because he is disabled, and this allows him to see who is at his front door via Alexa Echo. However, in order to talk to the person, he has to push a button on the Alexa Echo screen, which he is not able to do, as he is essentially a quadriplegic. Is anyone aware of a way to have it automatically allow you to talk through the doorbell or override this setting on Alexa Echo? It seems like Ring and/or Alexa would have some disability features... suggestions?
