I often set my iPhone to "do not disturb" overnight to avoid any early-morning calls that might come in from friends, solicitors, etc.
Even with "do not disturb" activated, I can allow certain calls--from phone numbers I designate as "favorites"--to come through.
My question is this: Is there a certain phone number for the COPS dispatch service that I can designate as a "favorite" to ensure that a call from them would get through while "do not disturb" is activated? Is there one such number that I can use?
