Make the Call Amazon Echo Show 8
Of course, making a "call" between Amazon Echo devices is simple. Say "Alexa, call [NAME]" and use the name of a pre-set contact. That works for voice calls on any Echo and video calls with an Echo Show. However, the Show will try to default to video if both people have a screen, so say "Alexa, video on/off" as needed, or look for the on/off button on the screen to toggle video off and make it a voice-only chat.
