call: transfer

Namespace: microsoft.graph

Transfer an active peer-to-peer call or group call.

Note: This is only supported if both the transferee and transfer target are Microsoft Teams users that belong to the same tenant. Transfer to PSTN number is supported only for application instance. To learn more about transferor, transferee and transfer target, see RFC 5589.

A consultative transfer means that the transferor can inform the person they want to transfer the call to (the transferee), before the transfer is made. This is opposed to transfering the call directly.

Permissions

One of the following permissions is required to call this API. To learn more, including how to choose permissions, see Permissions.

Permission type	Permissions (from least to most privileged)
Delegated (work or school account)	Not Supported
Delegated (personal Microsoft account)	Not Supported
Application	Calls.Initiate.All

HTTP request

POST /communications/calls/{id}/transfer

Request headers

Name	Description
Authorization	Bearer {token}. Required.
Content-type	application/json. Required.

Request body

In the request body, provide a JSON object with the following parameters.

Parameter	Type	Description
transferTarget	invitationParticipantInfo	The participant which is the target of the transfer.
transferee	participantInfo	The participant which is the transferee of the transfer. It is only needed when transfer from a group call.

Response

If successful, this method returns a 202 Accepted response code.

Examples

These examples show the flow of an incoming call all the way to the different types of transfer notifications.

Example 5: Call transfer from a group call

Note: To transfer from a group call, the transferee parameter is required. All other parameters are the same as those for a transfer from a peer-to-peer call. A consultative transfer from a group call or a transfer to PSTN from a group call are similar to examples 1-4, with the transferee parameter specified.
