The most common reasons an iPhone sends calls straight to voicemail include having Focus mode (or Do Not Disturb) enabled, Silence Unknown Callers turned on, call forwarding enabled, Airplane Mode activated, poor network signal, or blocked contacts. Other possibilities include software glitches or misconfigured settings. Key troubleshooting steps to fix this behavior:
- Check and turn off Focus mode or Do Not Disturb if active. A crescent moon icon indicates Do Not Disturb is on.
- Disable Silence Unknown Callers in the Phone settings.
- Ensure Airplane Mode is off.
- Verify that call forwarding is not enabled.
- Make sure your ringer is on and volume is up.
- Check that you haven’t blocked the caller.
- Restart the iPhone to clear minor glitches.
- Update iOS to the latest version.
- If problem persists, reset network settings or contact your carrier for network issues.
Following these steps typically resolves the problem of calls going straight to voicemail without ringing on an iPhone.
