The app is no longer maintained even though it's still for sale in the various Android app stores. It doesn't work for Nougat or higher versions, and I would rather not reward the developer for that behavior. Also, from my understanding, it may not be possible to programmatically produce this specific behavior in Nougat or higher versions (hangup, no ring, no voicemail), but I'm not totally certain.
