Just got my first smartphone, a Moto G5+ (Android 7.0 Nougat). I set-up Do Not Disturb so that only numbers from my contacts list would get through. My ringer volume is set to 100%. If I do a test call, my call gets through (I can see the call on the screen) but the phone doesn't ring. If I turn off Do Not Disturb, the phone will ring. My impression is that if Do Not Disturb is set to Priority>Calls from Contacts, a call from a contact should ring the phone the same as if Do Not Disturb were not in effect. No?
