Silence Unknown Callers on iPhone

![Silence Unknown Callers on iPhone](/api/v1/images/3a874bce-a64b-4439-89b4-a09bb37f5ee5)

## How to do it

1. Open **Settings**
2. Go to **Apps** → **Phone**
3. Enable **"Silence Unknown Callers"**
4. Done! Unknown numbers will now be sent directly to voicemail

## Why this helps

iOS uses artificial intelligence to recognize numbers. It checks not only your **Contacts**, but also numbers from your **Mail** and **Messages** apps. Only completely unknown callers (you've never had contact with) are silenced.

**What happens with silenced calls:**
- Caller goes directly to voicemail (can leave message)
- Appears in call list under "Missed"
- No ringing, no notification

**Important:** You might miss an important call (e.g., doctor from central number, delivery service, friend from unknown landline). Therefore: **check voicemail regularly** and **review call list**.

**When useful:**
- You get many spam calls
- Telemarketing annoys you
- You want peace from unknown numbers

**When NOT useful:**
- You often expect calls from new/changing numbers
- You work in customer service
- Medical emergencies (doctors might use new numbers)

**Alternative:** Manually block individual spam numbers: Call list → (i) → "Block Caller".

**Requirement:** iOS 13 or newer
