do not disturb - calls still get through

Thanks for stopping by the Apple Support Communities to get help with Do Not Disturb , MJC_,

Do Not Disturb can be a great way to ensure you aren't interrupted, but it does have an option to let certain calls through. For example, you can designate your Favorite contacts to always get through to you, no matter your Do Not Disturb settings. You can also set the feature up to allow multiple calls from the same number to be let through, if the second one comes within a specific time frame.

We would suggest checking to see if either of the above mentioned settings are enabled for Do Not Disturb, which you can do following the steps below. They're taken from the Apple Support article Use Do Not Disturb on your iPhone, iPad, and iPod touch - Apple Support, which will give you more information on the feature as a whole:

If you don't want to be disturbed at a certain time, you can set a schedule and change other Do Not Disturb features to help you concentrate. Here's how with iOS 15 and iPadOS 15:

1. Go to Settings > Focus. 

2. Tap Do Not Disturb.

3. Select settings for Allowed Notifications, Focus Status, Smart Activation, and more.

With iOS 14 or earlier, or iPadOS 14:

1. Go to Settings > Do Not Disturb.

2. Turn on Scheduled and set a schedule. 

3. Choose when you want to receive alerts, calls, and notifications:

Silence: Choose to silence calls and notifications always or only when the device is locked.

Allow Calls From: Allow calls from everyone, no one, your favorites, or specific contact groups stored on your device or iCloud.

Repeated Calls: If someone calls you twice within three minutes, the second call isn't silenced.

Cheers!
