# Conference Events

The Conference type exposes the following members.

Events

| Name | Description
--- | --- | ---
| ActiveTalkersChanged | Notifies the application that the list of active talkers in the conference has changed.
| ActiveVideoParticipantChanged | Notifies the application that the active video participant received over a video channel during a multi video channel conference call has changed.
| AlwaysDisplayActiveSpeakerVideoChanged | Notifies the application that the option that controls display of the active speaker's video has changed.
| BrandNameChanged | Notifies the application that the conference's brand name has changed. The brand name is the product family brand name associated with the conference system.
| CapabilitiesChanged | Notifies the application about a change in conference call's capabilities. The application can query the Conference object to find out about the capability that changed. Usually, the capabilities changed notification is tied to the features supported by the conference server as well as the local user's role (e.g., moderator, presenter, lecturer, etc.) in the conference call.
| ContinuationStatusChanged | Notifies the application that the continuation property of the conference has changed as a result of a local or remote operation.
| DisplayParticipantNameOnVideoChanged | Notifies the application that the option that controls display of the participant name in video image has changed.
| DroppedParticipantsChanged | Notifies the application that the list of participants that have dropped from the conference has changed.
| EncryptionStatusChanged | Notifies the application that the conference's encryption status has changed based on the encryption status of current participants on the call.
| EndTimeChanged | Notifies the application that the conference's end time has changed as a result of a local or a remote operation.
| EntryExitToneStatusChanged | Notifies the application that the conference's entry/exit tone enabled status has changed as a result of a local or remote operation.
| EventConferenceStatusChanged | Notifies the application that the conference's type has been changed.
| ExternalAdmissionStatusChanged | Notifies the application that the conference's external admission status has changed.
| LectureModeStatusChanged | Notifies the application that the conference's lecture mode status has changed as a result of a local or remote operation.
| LocalUserHandLowered | Notifies the application that the local user's hand has been lowered. This can occur when either the conference moderator or the local user lowers the hand.
| LocalUserHandRaised | Notifies the application that the local user's hand has been raised.
| LockStatusChanged | Notifies the application that the conference's lock status has changed as a result of a local or a remote operation.
| ParticipantsChanged | Notifies the application that the list of participants in the conference has changed.
| PasscodeRequired | Notifies the application that the end user is required to provide a conference admission passcode in order to join the conference call.
| PendingParticipantsChanged | Notifies the application that the list of participants waiting to enter the conference has changed.
| PermissionToEnterLockedConferenceRequired | Notifies the application that the end user is trying to join a locked conference call that does not require a passcode for entry.
| RecentTalkersChanged | Notifies the application that the list of recent talkers in the conference has changed.
| RecordingStatusChanged | Notifies the application that the conference's recording status has changed as a result of a local or a remote operation.
| ServiceAvailable | Notifies the application that the conference has a healthy signaling path. Depending on the network topology, the call session and the conference controls may share the same signaling connection (e.g., SIP and tunnel CCMP), or may use different connections. This is why separate service available / unavailable events are provided for the Call and Conference objects.
| ServiceUnavailable | Notifies the application that the conference does not have a healthy signaling path. Depending on the network topology, the call session and the conference controls may share the same signaling connection(e.g., SIP and tunnel CCMP), or may use different connections. This is why separate service available / unavailable events are provided for the Call and Conference objects.
| Started | Occurs when the conference has started. This only occurs when the WaitingToStart event was previously raised.
| StreamingStatusChanged | Notifies the application that the conference's streaming status has changed.
| SubjectChanged | Notifies the application that the conference's subject/title has changed.
| SupportedVideoLayoutsChanged | Notifies the application that the list of available layouts supported by the conference system has changed.
| VideoChannelReceiveStatusChanged | Occurs during a multi video channel conference call when the server either starts or stops sending video packets over a video channel.
| VideoLayoutChanged | Notifies the application that the layout of the video image created by the conference system has changed.
| VideoSelfSeeChanged | Notifies the application that the self-see option for the video image created by the conference system has changed.
| VideoStatusChanged | Notifies the application that the conference's video enabled status has changed as a result of a local or a remote operation.
| WaitingToStart | Notifies the application that the conference has not started, and the local user is waiting for the conference to start (i.e. moderator to join). At this point, the conference server may provide wait treatment to the end user, e.g., by playing music and/or displaying a still video image. This information is reported based on an indication received from the conference server and may not be provided depending on the server's capabilities.
