Is it possible to make phone calls in background?

MIT App Inventor Help

I'm programming an Intercom App. My idea is to have in the lobby of a buiding an enclosed phone with a screen similar to a phone application. But instead of entering the phone number the user enters the number of the apartment and the app search for the phone(s) number(s) in a table apartment-phone and make a call...

So far so good...

My problem starts when the app makes the phone call it opens the "Phone" app in the phone and the "real" number of the person livin in the apartment shows in screen... and that is a security issue!!!!

Is there any way of make a phone call without exit from my app? or make the phone call in background?

this is a real security issue!!!!

Hi. Have you find a solution to make call in background? I am searching for a similar task to monitor a device which i sent a command to play a song via text message, to check if the song is finished.

You might consider a UDP extension, which can provide direct communication between devices.

It's not the real solution, but by using a @Taifun :+1: :+1: :+1: (puravidaapps.com) "Setting extension" you can set the brightness of the phone nearly to 0 before starting the phone app. Then you can restore to the previous value when done with the call.
I don't really know if the launched app (the Phone app) wil maintain the brightness set by your app, but it worths a test ?
Cheers.
