I'm sorry to hear that you're experiencing issues with connecting to the web call. It's great that you've already checked your microphone permissions. Since the microphone is enabled, the issue might be related to the connection with the call provider or a temporary service disruption.
Could you please try the following steps to see if they resolve the issue?
1. Refresh your browser or restart the app you're using for the call.
2. Ensure that your internet connection is stable.
3. Check if there are any updates available for your browser or app that might fix the issue.
4. Try using a different browser or device to see if the problem persists.
If you've tried these steps and the problem continues, please let me know so we can investigate further.
