events property
This call's events (callId matches). Switch on TcccEvent.type
(progress, accepted, confirmed, newDTMF, … / TcccEventType).
WSS stays on TcccUserCall.events; TRTC reconnect uses
TcccServerType.trtc here. accepted is SIP 200; talkable is
isEstablished.
Implementation
@override
Stream<TcccEvent> get events => _events.stream;
