I suggest to add a function on android APP that makes the phone play, vibrate a tone to notify an event. It should be good too to show a message alert with text, but not a push notification, because push notification are difficult to find. I use Make to notify me about a new customer wants a call. "Prepare a phone call" is dangerous, because you can call witout knowing it. It would be useful too a module which sends to make app personalized text information. It would help to control some make apps from the mobile.
