Question

So I want to receive a notification, when a call is happening callRecord (/communications/callRecords) so I grabed myself this example and changed the task function to this:

public async Task<ActionResult<string>> Get()
        {
            var graphServiceClient = GetGraphClient();

            var sub = new Microsoft.Graph.Subscription();
            sub.ChangeType = "created";
            sub.NotificationUrl = config.Ngrok + "/api/notifications";
            sub.Resource = "/communications/callRecords";
            sub.ExpirationDateTime = DateTime.UtcNow.AddMinutes(5);

            var newSubscription = await graphServiceClient
              .Subscriptions
              .Request()
              .AddAsync(sub);

            Subscriptions[newSubscription.Id] = newSubscription;

            if (subscriptionTimer == null)
            {
                subscriptionTimer = new Timer(CheckSubscriptions, null, 5000, 15000);
            }

            return $"Subscribed. Id: {newSubscription.Id}, Expiration: {newSubscription.ExpirationDateTime}";
        }

I also added the graph api permission CallRecords.Read.All to my app. Beforehand I testet the example with the updated users notification and it worked fine. But now it won't trigger the notification for a call.

Same here, everything worked yesterday but today my webhook endpoint didn't even trigger once.

I think there might be an issue on Microsoft's side. I follow this issue here of someone who has the same problem as us.

UPDATE: Someone from Microsoft answered in the linked Github Issue:

There is currently an ongoing issue. The related post is TM220340 in the M365 Admin Center.

So they're confirming that the issue is on their end.
