Call cancelled
Call cancelled call.session.cancelled
Key fields
No event-specific extension fields; business data is in Common payload (deviceId, channelId, time, etc.).
Notes
Subscribe to capabilityEvent in setMessageCallback. msgType matches the event ID in this page title (call.session.cancelled, same as the Event types index). For the V2 push payload (deviceId, productId, outputData, etc.), see Common payload and Receive alarm messages; this page summarizes outputData only. Query/receive requires message permission Talk (call.session; see Permission codes) (see Message permissions).
Doorbell/intercom session events: typical flow called → (SDK answer/reject/hang up) → answered/refused/hungUp/cancelled, not the device.service.invoke answer leaf. Live talk uses Talk (property/list); message push uses Alarm. For cancelled, outputData is often {}.
