Do Not Disturb silences notifications but doesn't automatically send calls to voicemail
Do Not Disturb (often called DND) mutes alerts on your phone — calls, texts, and notifications won't make sounds or light up your screen. But the calls still come through to your phone. Whether they go to voicemail depends on your settings and which device you're using.
On most phones, incoming calls will ring through silently in the background while Do Not Disturb is on. You won't hear or see them unless you're looking at your phone at that exact moment. If you don't answer, the call goes to voicemail the same way it would normally. The caller experiences no difference — they don't know your Do Not Disturb is on.
Some phones let you change this behavior. You can set Do Not Disturb to send calls straight to voicemail without ringing at all, or to allow calls from specific contacts (like family or work) to ring through while blocking everyone else. These options live in your phone's settings, not in Do Not Disturb itself.
Key Takeaways
- Do Not Disturb silences your phone's sounds and notifications, but incoming calls still reach your phone and will go to voicemail if you don't answer.
- Callers cannot tell that Do Not Disturb is on — the call behaves normally from their side.
- You can customize Do Not Disturb to allow calls from specific contacts (like family) to ring through while silencing everyone else.
- If you want calls to go straight to voicemail without ringing at all, you need to use a different feature like Call Screening or a custom rule, not Do Not Disturb alone.
How Do Not Disturb works on iPhone
On iPhone, Do Not Disturb silences calls, texts, and notifications so your screen stays dark and your phone stays quiet. The calls still arrive — they just don't alert you. If someone calls while Do Not Disturb is on, the call goes to voicemail after a few rings, and you'll see a missed call notification later.
You can customize which calls get through. In Settings > Focus (or Do Not Disturb on older iPhones), you can allow calls from specific contacts or groups. For example, you might let calls from "Favorites" ring through while silencing everyone else. Calls from numbers not on your allowed list will go straight to voicemail.
You can also set Do Not Disturb to turn on automatically at certain times, in certain locations, or when you open a specific app. This is useful if you want your phone silent during work hours or while you're driving, without having to remember to turn it on manually.
How Do Not Disturb works on Android
Android's Do Not Disturb (called "Do Not Disturb" on most phones, though Samsung calls it "Quiet Mode") works similarly to iPhone. Calls and notifications are silenced, but incoming calls still reach your phone and go to voicemail if unanswered.
Android gives you more granular control over what gets through. You can allow calls from contacts, from starred contacts, or from repeat callers (someone who calls twice in 15 minutes). You can also set different rules for different times of day or different apps. Some Android phones let you send calls directly to voicemail without ringing, though this is usually a separate setting from Do Not Disturb itself.
Like iPhone, you can schedule Do Not Disturb to turn on automatically. You can also create different profiles — for example, one for work hours and one for sleep — each with its own rules about which calls and notifications get through.
The difference between Do Not Disturb and blocking a contact
Do Not Disturb affects all incoming calls equally (except those you've whitelisted). Blocking a contact prevents that specific person from reaching you at all — their calls go straight to voicemail, and they may not even know the call didn't go through.
If you block someone, they cannot call you, text you, or reach you through FaceTime or other apps, depending on your phone's settings. If you use Do Not Disturb, everyone can still reach you — you just won't be notified. The difference matters if you want to avoid someone specific versus avoiding all interruptions for a while.
When to use Do Not Disturb versus other features
Use Do Not Disturb when you want temporary silence but need to stay reachable for emergencies. It's useful during meetings, movies, sleep, or focused work. You can allow calls from important contacts so you won't miss a real emergency.
Use Call Screening (on iPhone) or Call Filter (on Android) if you want to filter out spam or unknown numbers automatically. These features let you review calls from unknown contacts without being interrupted, and you can answer if you recognize the number.
Use blocking if someone is harassing you or you don't want them to reach you at all. Blocking is permanent until you unblock them; Do Not Disturb is temporary and affects everyone equally (except whitelisted contacts).
What happens to texts and notifications during Do Not Disturb
Text messages and app notifications are silenced the same way calls are — they won't make sounds or light up your screen. You'll still receive them, and you can read them when you unlock your phone. They'll be waiting for you when Do Not Disturb turns off.
Some phones let you allow texts from specific contacts even while Do Not Disturb is on. This is useful if you want to silence most notifications but stay reachable by family or a work group chat. Check your Do Not Disturb settings to see if you can customize which contacts can text you.
Common misunderstandings about Do Not Disturb
Many people think Do Not Disturb blocks calls entirely, like blocking a contact does. It doesn't — calls still come through, they just don't alert you. If you're actively using your phone, you might see an incoming call appear on your screen even with Do Not Disturb on.
Another common misunderstanding: that Do Not Disturb hides your activity from others. It doesn't. Your location sharing, read receipts, and online status all continue as normal. Do Not Disturb only affects what alerts you on your own phone.
Some people also think Do Not Disturb uses more battery because it's "running" in the background. It doesn't — it's just a setting that changes how your phone handles notifications. It may actually save battery by preventing your screen from lighting up constantly.
Frequently Asked Questions
Can someone tell if I have Do Not Disturb on?
No. From the caller's perspective, your phone rings normally and goes to voicemail if you don't answer. They have no way to know whether you declined the call, didn't hear it, or had Do Not Disturb on. The call behaves identically either way.
Will calls from my mom still ring if I have Do Not Disturb on?
Only if you've added her to your allowed contacts in Do Not Disturb settings. On iPhone, go to Settings > Focus > Do Not Disturb > Allowed Contacts. On Android, go to Settings > Do Not Disturb > Exceptions or Allowed Contacts. If she's not on that list, her call will be silenced like any other.
Does Do Not Disturb stop spam calls?
No. Do Not Disturb silences all calls equally. If you want to block spam, use Call Screening (iPhone) or Call Filter (Android), which can identify and silence suspected spam before it reaches you. You can also block specific numbers manually.
What's the difference between Do Not Disturb and Airplane Mode?
Do Not Disturb silences notifications but keeps your phone connected to the network. Airplane Mode disconnects your phone entirely — no calls, texts, or data come through at all. Use Do Not Disturb for temporary silence; use Airplane Mode when you truly cannot be reached.
Can I set Do Not Disturb to send calls straight to voicemail without ringing?
On iPhone, Do Not Disturb doesn't have this option built in. On some Android phones, you can create a custom rule or use a separate feature to send calls directly to voicemail. Check your phone's Do Not Disturb or Call Settings to see if this option exists. Otherwise, you may need a third-party app.
