How do I stop WhatsApp calls from unknown numbers ringing in the dinner rush?

Turn on Silence unknown callers under Privacy, then Calls. Your phone will not ring, but the calls still show in your Calls tab.

• New customers you have not saved count as unknown, so their calls are silenced too.
• Silenced calls still appear in the Calls tab and in Notifications.
• Check the Calls tab between rushes and call back.
• Tell customers on your profile that ordering is faster by message or link.
• Switch the setting off again when you want every call to ring.
