Namespace: microsoft.graph

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

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.

This API is available in the following national cloud deployments.

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