What to Do
- Move to an area with better reception

4. Call Blocking or Silence Unknown Callers
If the caller is blocked or unknown, your iPhone may automatically send them to voicemail.

Understanding iPhone’s Call and Voicemail Settings
Adjusting call and voicemail settings on an iPhone can help avoid missed calls and improve connectivity. Below, important areas affecting these settings are examined.
Configuring Do Not Disturb and Focus Modes
Do Not Disturb mode silences all calls and alerts. In the Settings app, navigate to Do Not Disturb. Ensure it is off, or customize it to allow calls from certain contacts.
Focus Modes work similarly. Go to Settings > Focus and check active modes. These settings help manage when notifications come through, preventing calls from going directly to voicemail.
Addressing Network and Connectivity Issues
Calls may go straight to voicemail due to network problems. Check the signal bars in the top corner of the screen. Airplane Mode might be on or cellular data off.
It can help to reset network settings. Go to Settings > General > Reset > Reset Network Settings. This clears saved Wi-Fi networks and passwords, fixing connectivity problems.
Examining Call Settings Features
Review Call Forwarding settings. Navigate to Settings > Phone > Call Forwarding. Ensure it is off unless you want calls forwarded to another number.
Also, check if Silence Unknown Callers is on. This setting sends calls from unknown numbers straight to voicemail. Navigate to Settings > Phone to disable it if needed.
Investigating Software and Carrier Updates
Updating to the latest iOS can fix bugs. Go to Settings > General > Software Update and install any updates. Updated iOS can solve common issues and improve performance.
Carrier settings also may need updating. Open Settings > General > About. If an update is available, you’ll see a prompt to install it. This keeps your device compatible with network changes.
Reviewing Potential Hardware Influences
Hardware issues can cause calls to go to voicemail. SIM card problems can interrupt service. Reinsert the SIM card to ensure it’s seated correctly.
Check the Ringer/Silent Switch on the side of the phone. If the switch is in silent mode, you may miss calls. Also, inspect ringer volume settings in Settings > Sounds & Haptics to ensure the volume is not too low.
