Voice over IP phone service starts with checking your internet connection, as VoIP heavily relies on a stable network. Ensure your bandwidth is sufficient for the number of concurrent calls and that no other devices are hogging the bandwidth.

If problems persist, contact your VoIP provider for further support, as they may need to adjust settings on their end to improve call quality and connectivity.
