Create call

Namespace: microsoft.graph

Create call enables your bot to create a new outgoing peer-to-peer or group call, or join an existing meeting. You will need to register the calling bot and go through the list of permissions needed as mentioned below.

This API is available in the following national cloud deployments.

Global service US Government L4 US Government L5 (DOD) China operated by 21Vianet

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type Least privileged permissions Higher privileged permissions

Delegated (personal Microsoft account) Not supported. Not supported.
Application Calls.JoinGroupCalls.Chat Calls.Initiate.All, Calls.InitiateGroupCall.All, Calls.JoinGroupCall.All, Calls.JoinGroupCallAsGuest.All

Notes:

  • For a call with app-hosted media, you need the Calls.AccessMedia.All permission in addition to one of the permissions listed in the previous table.
  • Cloud Video Interop solutions that are Certified for Microsoft Teams have permission to call this API to join meetings for which they have meeting join links, similar to external users joining through a browser.
  • The Calls.JoinGroupCalls.Chat permission uses resource-specific consent.

Example 5: Join scheduled meeting with service hosted media

To join the scheduled meeting, you need to get the thread ID, message ID, organizer ID, and the tenant ID in which the meeting is scheduled. You can get this information by using the Get onlineMeeting API.

The values of authorization token, callback URL, application ID, application name, user ID, user name, and tenant ID must be replaced along with the details obtained from the Get onlineMeeting API with actual values to make the example work.

Note: This example needs the Calls.JoinGroupCalls.All permission.

Example 9: Create peer-to-peer PSTN call with service hosted media

Note: This call requires the Calls.Initiate.All permission.

This call requires an application instance with a PSTN number assigned. For details, see Assign a phone number to your bot.

Request

The following example shows the request to make a peer-to-peer call between the bot and a PSTN number. In this example, the media is hosted by the service. The values of authorization token, callback URL, application instance ID, application instance display name, phone ID and tenant ID must be replaced with actual values to make the example work.

Note: Application instance ID is the object ID of application instance. The application ID that application instance links to should match the one in authorization token. Phone ID is the phone number in E.164 format.
