Spam and scam calls on WhatsApp have become increasingly common, making it difficult for users to distinguish genuine calls from unwanted ones. To help improve user privacy and reduce interruptions, WhatsApp offers a built-in feature called "Silence Unknown Callers."

When enabled, this feature automatically silences voice calls from phone numbers that are not saved in your contacts, while still recording them in your call history. This allows you to review missed calls later without being disturbed by unknown callers.

Here's how the feature works and why you may want to enable it.

What Is the 'Silence Unknown Callers' Feature?

The Silence Unknown Callers option is a privacy feature designed to reduce unwanted interruptions from unfamiliar numbers.

After turning it on:

• Calls from unknown numbers will not ring on your phone.
• The call will be automatically silenced.
• Missed calls will still appear in the Calls tab.
• You can review the number later and decide whether to call back, ignore it, or block it.

This ensures you remain aware of incoming calls without having to answer potentially unwanted ones immediately.

Why Should You Enable This Feature?

Unknown WhatsApp calls are often associated with spam, promotional campaigns, or attempted scams.

Enabling the feature can help you:

• Reduce interruptions from unknown callers.
• Minimize the chances of answering spam calls.
• Add an extra layer of privacy to your WhatsApp account.
• Continue receiving calls normally from people saved in your contacts.
• Review missed calls at your convenience before responding.

What Happens After You Turn It On?

Once the feature is enabled:

• Your phone will not ring for calls from unsaved numbers.
• WhatsApp silently blocks the ringtone while still registering the call.
• The missed call remains visible in your call log.
• You retain complete control over whether to return the call or block the number.

Importantly, the feature does not block unknown callers entirely—it simply silences them.

How to Enable 'Silence Unknown Callers'

The process is similar on both Android and iPhone.

Follow these steps:

1. Open WhatsApp.
2. Tap the three-dot menu (Android) or Settings (iPhone).
3. Select Privacy.
4. Scroll down and tap Calls.
5. Turn on Silence Unknown Callers.

After enabling the setting, WhatsApp will automatically silence incoming calls from numbers that are not saved in your contact list.

How This Feature Improves Security

Cybercriminals sometimes use WhatsApp voice calls to contact potential victims before attempting fraud or phishing scams.

Silencing unknown callers can help reduce disturbances from:

• Spam calls
• Fraud attempts
• Impersonation scams posing as banks or government agencies
• Unwanted promotional calls

While the feature cannot prevent scammers from attempting to call, it gives users more time to verify unfamiliar numbers before responding.

Additional Ways to Stay Safe on WhatsApp

To improve your account security, consider following these best practices:

• Enable two-step verification.
• Never share OTPs or verification codes with anyone.
• Avoid answering suspicious calls requesting personal or banking information.
• Block and report suspicious accounts.
• Keep WhatsApp updated to the latest version to receive new security features.

Final Thoughts

The Silence Unknown Callers feature is a simple but useful privacy tool for anyone who receives frequent calls from unfamiliar WhatsApp numbers. Instead of interrupting your day, unknown calls are automatically silenced while remaining visible in your call history for later review.

If you're receiving regular spam or scam calls on WhatsApp, enabling this feature can help reduce unwanted interruptions and add another layer of protection to your messaging experience.
