Azure Communication Services - Voice and video calling events

Article
06/22/2023

This article provides the properties and schema for communication services voice and video calling events. For an introduction to event schemas, see Azure Event Grid event schema.

Events types

Azure Communication Services emits the following voice and video calling event types:

Event type	Description
Microsoft.Communication.RecordingFileStatusUpdated	Published when recording file is available
Microsoft.Communication.CallStarted	Published when call is started
Microsoft.Communication.CallEnded	Published when call is ended
Microsoft.Communication.CallParticipantAdded	Published when participant is added
Microsoft.Communication.CallParticipantRemoved	Published when participant is removed
Microsoft.Communication.IncomingCall	Published when there is an incoming call

Event responses

When an event is triggered, the Event Grid service sends data about that event to subscribing endpoints.

This section contains an example of what that data would look like for each event.

Limitations

Aside from IncomingCall, Calling events are only available for ACS VoIP users. PSTN, bots, echo bot and Teams users events are excluded. No calling events will be available for ACS - Teams meeting interop call.

IncomingCall events have support for ACS VoIP users and PSTN numbers. For more details on which scenarios can trigger IncomingCall events, see the following Incoming call concepts documentation.

Next steps

See the following tutorial: Quickstart: Handle voice and video calling events.
