Alexa is an intelligent app that works on AI. It will do whatever you say, be it playing songs, switching on and off any other smart device or even calling someone from your phone book. But calling someone would require you to do these steps with caution:
• Firstly select the conversation icon which would be visible on the home screen.
• Now tap on the contact icon that would be available on the top right corner.
• By doing this you would be able to see all the contacts who use Echo devices or have the Alexa app.
• Once your contacts are visible just dial their number.
