call: reject

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.

Enable a bot to reject an incoming call. The incoming call request can be an invite from a participant in a group call or a peer-to-peer call. If an invite to a group call is received, the notification contains the chatInfo and meetingInfo parameters.

The bot is expected to answer or reject the call before the call times out. The current timeout value is 15 seconds.

This API doesn't end existing calls that have already been answered. Use delete call to end a call.

This API is available in the following national cloud deployments.

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