I hope this will give you the info you are looking for to make your IP5 Do Not Disturb work as you expect it. Have a great day.
[INFO]Do Not Disturb and NotificationsPush notifications appear in Notification Center and alert you to new information, even when the
associated app isn’t running. Notifications vary by app, but may include text or sound alerts, and
a numbered badge on the app icon on the Home screen.
Turn off all notifications: Go to Settings and turn on Do Not Disturb. If it’s on and iPhone is
locked, all notifications and calls are silenced, but alarms will still sound. You can set the following
options in Settings > Notifications > Do Not Disturb:
• Automatically turn on Do Not Disturb: Turn on Scheduled, then set the time when you don’t
want to be disturbed. iPhone automatically turns on Do Not Disturb during this period
each day.
• Allow some phone calls during Do Not Disturb: When Do Not Disturb is on, ringing is silenced.
To allow calls from some callers to ring, tap Allow Calls From. You can allow calls from your
Favorites list, or from other Contacts groups you define. For information about Favorites, see
Chapter 25,Contacts, on page 100.
• Allow persistent callers to ring through: Turn on Repeated Calls. If the same caller (based on
their Caller ID) calls you again within three minutes, iPhone will ring.
Turn an app’s notifications on or off: Go to Settings > Notifications. Tap an item in the list, then
turn notifications on or off for that item. Apps that have notifications turned off appear in the Not
In Notification Center list.[/INFO]
