It seems to me that the key issue in the Echo Show call setup is being able to setup Alexa App on Either a PC/Mac (OR) Smartphone/Tablet.
Has anyone set this up without using SmartPhone?
I understand "Alexa-to-Alexa calling" is designed for compatible Echo devices and the Alexa for iOS or Android app for phones or tablets, so I assume once you are on WiFi with the Echo Show, you no longer need to have with Smartphone nearby.
I know this for a fact because for my wife's 88 year old mother we set hers up with the Alexa App installed with my wife's Smartphone, and my smartphone was used to set up our local Echo Show.
But I am wondering if you really need to use the smartphone itself?
Can you set up the Alexa app on a PC/Mac or Kindle Fire, and manually enter contacts from there?
