I have an Echo Plus, and my parents have an Echo 2. I have an iPhone with the Alexa app on and Echo/Alexa has imported my contacts. My parents, on the other hand, are so old school, they don't even have a smart phone, so therefor no Alexa app. Because they have no Alexa app, how can they set up their phone to make and receive calls from me? Any ideas would be appreciated. Hopefully Im just being stupid and am missing something really obvious.
