Alexa isn’t the only one you can talk to through your Echo device. You can also place and receive voice calls with other people. The Alexa app supports Alexa-to-Alexa calling on an iPhone with iOS 9.0 or higher, and an Android phone with Android 5.0 or higher. With an Echo Show, you can place and receive video calls.
Echo devices also use an intercom-like system called Drop In to call other Echo devices directly, either in your home or another household. It works with most mobile phones and landlines in the US and certain other countries. Here’s how to enlist Alexa as your own phone operator.
To get started, open the Alexa app on your phone and tap the Communicate icon at the bottom. If you haven’t already registered for Alexa-to-Alexa calling, you’re asked to confirm your name, allow access to your contacts, and verify your phone number.
