calls received not ringing on iphone

Disable Do Not Disturb On Your iPhone

1. Launch the Settings app on your iPhone.
2. Tap on the Do Not Disturb option.
3. Turn the toggle for Do Not Disturb to the off position.

Make Sure The iPhone Speaker Works

If your iPhone’s speaker is broken or a part of the speaker hardware is malfunctioning, it could cause your iPhone not to play any sounds including for incoming phone calls. One way to verify this is to try and play some music on your phone.

Turn Off Call Forwarding On Your iPhone

If call forwarding is enabled on your iPhone, it’ll forward all your incoming calls to your specified number or to your voicemail. This may be why your iPhone is not ringing, as it’s simply receiving any calls because those calls are being sent to the forwarded number.

Disabling call forwarding will fix the issue.

1. Open the Settings app on your iPhone.
2. Scroll down and tap on the Phone option.
3. Find Call Forwarding and tap on it.
4. Disable the Call Forwarding option.
