Why are calls going straight to voicemail when using apps?

Calls might go straight to voicemail when using apps due to features like "Do Not Disturb" or "Focus" modes, call forwarding, or if your phone is in airplane mode, or if you have blocked the number. 

Here's a breakdown of potential reasons and solutions:

• Do Not Disturb/Focus Modes:
• Many phones have modes that silence calls and send them to voicemail, such as "Do Not Disturb" or "Focus" modes on iOS and Android. 
• Call Forwarding:
• If you've enabled call forwarding, your calls might be redirected to another number or voicemail, even if you're using an app. 
• Airplane Mode:
• When airplane mode is on, your phone's cellular network is disabled, and incoming calls will go straight to voicemail. 
• Blocked Numbers:
• If you've blocked a specific number, calls from that number will go directly to voicemail. 
• Network Issues:
• A weak signal or network problems can also cause calls to go straight to voicemail. 
• App-Specific Issues:
• Some apps might have their own settings that affect call handling, so check the app's settings to see if there are any relevant options. 
• SIM Card Issues:
• If there's a problem with your SIM card, it could also cause calls to go straight to voicemail. 
• Ringer Volume:
• Ensure that your ringer volume is turned up and that your phone is not on silent mode. 
• Check Phone Settings:
• Navigate to your phone's call or phone settings to check for any features that might be causing calls to go straight to voicemail. 
• Restart Your Phone:
• A simple restart can sometimes resolve temporary glitches that might be causing this issue. 
• Update Carrier Settings:
• Ensure that your carrier settings are up to date.
