Make call phone without showing it by Ionic App (iOS + Android)

Hi everybody,
i’m trying to build an HTML5 Ionic App (for iOS and Android) that can do a phone call without showing anything on the screen. The problem is that the app is supposed to record a video while the app is making a phone call to some specific number; then, when the specific number’s person answers, the app plays a recorded voice. Something like “Hi, you have been called by “APP_NAME” because of bla bla bla”.
Is it possibile?
