To troubleshoot the issue, you can try the following steps:
Verify the Azure Communication Services resource: Make sure that the Azure Communication Services resource you are using is in the correct state and functioning properly. You can check the resource status in the Azure portal.
Check service health: Check the Azure Service Health dashboard or the Azure Status page to see if there are any ongoing issues or outages affecting Azure Communication Services.
Retry after some time: As the error message suggests that the services are not available at the moment, it could be a temporary issue. You can wait for some time and then retry the operation.
Review your code: Ensure that you have followed the code provided in the Azure Communication Services documentation accurately. Double-check the API endpoints, request payload, authentication, and any other relevant configurations.
Contact Azure Support: If the issue persists or you need further assistance, you can reach out to Azure Support for help in troubleshooting and resolving the issue.
Remember to provide any relevant error details, request payload, and any other information that can help the support team investigate the issue effectively.
