If you have the Amazon Echo with Alexa, I highly recommend that you install Alexa voice calling for telephoning.
This will avoid the necessity of running to the phone whenever you want to make a call, or for those who have set up Alexa phoning, running to receive calls, a big benefit for seniors who are not quite so mobile anymore
To set up Alexa phoning, you will need to uninstall your Alexa app on your phone and then reinstall it. Then, when you restart the app, Alexa will take you through the process of setting up calling using your existing contacts.
You may want to modify some of those contacts so that you can call with the first name only as the (voice) contact name.
Once set up, the people icon on the conversation screen will tell you who else in your contacts is setup to make and receive Alexa calls.
