If you have an Amazon Echo Show 10, Echo Dot, Echo Flex, or even the new Echo Show 15, you might consider ditching your landline. Not only can you try cool Alexa music hacks and tons of commands, but you can also use Alexa to call or send a message to another Echo device. All you have to do is “Alexa, call mom” or “Alexa, call (put the name of the person you want to reach here)” and you can start an echo-to-echo voice or Video call.
But if you want it to work, you both need to run the function in your respective Alexa apps. That’s how it’s done.
