There are several potential reasons for distorted/muted voice calls on an iPhone. Here are some common factors that can contribute to this issue:

1. A weak or unstable cellular network signal can result in voice call distortion. If the signal strength is low, the audio quality may suffer, leading to distortion, dropouts, or static during calls.
2. High network traffic or congestion can affect voice call quality. When there are too many users trying to access the network simultaneously, it can result in degraded call quality or distortion.
3. It's recommended to keep your iPhone's software up to date and regularly check for app updates.
4. If you are using a Bluetooth headset or speakerphone during calls, interference or compatibility issues can lead to distorted audio. Try disconnecting any connected Bluetooth devices and check if the voice quality improves.
5. Voice call distortion can also be attributed to problems on the network provider's end. Temporary network outages, infrastructure issues, or maintenance work can affect call quality in specific areas or during certain times.

If you're experiencing persistent voice call distortion on your iPhone, it's recommended to troubleshoot the problem by following these steps:

1. Check your network signal strength and switch to a different location if possible to see if the issue persists.
2. Restart your iPhone to refresh the software and temporary settings.
3. Disable any Bluetooth devices connected to your iPhone during calls and check if the distortion improves.
4. Verify that your iPhone's software is up to date and install any available updates.
5. Contact your network provider to inquire about any known issues in your area.
6. If the problem persists, consider contacting or visiting an Apple authorized service center to diagnose and address any hardware-related problems.
