I don't see why not. That's the point of call and messaging feature in the app right? Anyway reminds me. When we go away I use my 2 old phones as security cam. And since they have alexa on app now. My husband actually told me to turn on light in the bedroom so we can see coz the room was dark when I check on it at night.
Imagine the magic of technology when we were in Canada, I turn my bedroom light on! and off! in alexa app. I also can do it manual but where's the fun in that. So I told my husband, there you go, magic of technology. I also of course can see what's going on in our room while away in another country! Woot.
