To troubleshoot poor call quality, here are some steps that can be taken:
Check your internet connection. If it’s slow or intermittent, it could be affecting your call quality. Check the speed of your connection and make sure it meets the minimum requirements for your call.
Make sure your computer meets the minimum system requirements to run the application.
Check the microphone and speakers you are using. Make sure they are connected properly and that the levels are set correctly.
Test the audio by setting up a test call with another person or device.
