We are currently utilizing an Azure Communication Service subscription (Free Trial) and have configured Event Grid Subscriptions resource to monitor specific events, including "Call Started," "Call Ended" and "Incoming Call".

As part of this setup, we have configured a webhook endpoint to receive notifications for these events. However, we have encountered an issue where the incoming events does not invoke webhook endpoint when we attempt PSTN (Outbound / Inbound) calls.

We would greatly appreciate your assistance in resolving this matter and understanding how we can ensure the incoming events invoking webhook endpoint when making outbound or inbound PSTN calls.

Please let us know if you require any additional information or access to our Azure resources to assist in diagnosing and rectifying the problem.

    @Sai Shashank Thanks for reaching out and apology for the inconvenience due to this issue. In case if you are still facing the issue, I will suggest to review the event grid custom topic that was created/configured and validating whether you see any Published events metrics count when you have performed the operation. Once you have validated that the event is received at your custom topic end then I will suggest you to review your event grid subscription metrics to validate whether it tried to deliver that event to the configured webhook endpoint and if you have configured the dead letter then please validate the logs at your storage account end to validate the reason why the events were moved to dead letter queue.

    In case if you need any help in validating the above then please let me know so I can review and assist you.
