If Do Not Disturb is set to “People: None allowed” but calls are still coming through on iOS 26.3.1, it means another setting is overriding DND.
You can try the following to stop calls completely during DND:
● Check “Allow Repeated Calls” by OPENING Settings ➡️ Focus ➡️ Do Not Disturb ➡️ People and make sure Allow Repeated Calls is turned OFF. This prevents callers from breaking through by calling twice within three minutes
● Check “Silence” mode by OPENING Settings ➡️ Focus ➡️ Do Not Disturb and set Silence to “Always”. This ensures calls are silenced even when the phone is unlocked
● Check “Focus Filters” by OPENING Settings ➡️ Focus ➡️ Do Not Disturb ➡️ Focus Filters and remove any filters. This prevents apps or contacts from bypassing DND
● Check “Share Across Devices” by OPENING Settings ➡️ Focus and turn OFF Share Across Devices. This prevents another Apple device from overriding your iPhone’s DND settings
● Check your Phone app settings by OPENING Settings ➡️ Apps ➡️ Phone ➡️ Silence Unknown Callers and set it how you prefer. This setting can override Focus behavior
