How can I fix call failure issues on Apple Watch Series 10?

On my Apple Watch Series 10, I have encountered recurring issues with call functionality. Calls either fail to connect or produce static or no sound, despite the watch indicating a successful connection. Additionally, have reported similar problems, where they are unable to hear the call or experience broken-up audio.

To address these issues, I have performed the following troubleshooting steps:

* Restarted both my phone and watch.

* Refreshed the WiFi and Bluetooth connections on both devices.
