Getting started with Microsoft Teams call record data and Azure Functions

Register your application

When you register an application with Azure Active Directory, you create an identity configuration. The Azure Functions use the application for authentication when interacting with the Microsoft Graph API. Assign the following permissions to the Azure AD app registration:

• CallRecords.Read.All (Application)
• Subscriptions.Read.All (Delegated)

Deploy the functions to Azure

From the open-source repository, click the Deploy to Azure button to deploy the Functions.

During setup, you will be prompted for the following information:

• Client ID
• Client Secret
• Splunk HTTP Event Collector Endpoint
• Splunk HTTP Event Collector Token

Use Microsoft Graph subscription functions

A Microsoft Graph subscription defines where Microsoft should deliver notifications.

To create a subscription:

1. Launch the Azure Portal.
2. Navigate to the Function app section in the portal.
3. Select the Function app created previously.
4. Click Functions > create-subscription. Only callRecords subscriptions are created in version 1.x of the functions.

   

5. In the Overview section, click Get Function Url.
6. Copy the URL and paste it into a new browser tab.

   

   You might receive a timeout when executing this function for the first time. In this event, refresh your browser. The reason for this is that the create-subscription function makes a call to the subscription-webhook function which might not be running yet.

Additional actions you can take are:

1. To list subscriptions, run the list-subscriptions function.
2. To delete a subscription, copy the subscription's ID field and pass it as a query parameter named subscriptionId to the delete-subscription function. For example: https://FUNCTION-APP.azurewebsites.n...UBSCRIPTION_ID

View data

In the Splunk platform, run the following search:

After the call record data is ingested, the Microsoft 365 App for Splunk has several out-of-the-box dashboards to visualize common use case scenarios for Microsoft Teams call record data. For more details, refer to Getting started with Microsoft Teams call record data.
