SinchCallDelegate

public protocol SinchCallDelegate : AnyObject

The delegate of a SinchCall object must adopt the SinchCallDelegate protocol. The required methods handle call state changes.

Call State Progression

For a complete outgoing call, the delegate methods will be called in the following order:

callDidProgress:
callDidRing:
`callDidAnswer:
callDidEstablish:
callDidEnd:

For a complete incoming call, the delegate methods will be called in the following order, after the client delegate method SinchClientDelegate client:didReceiveIncomingCall: has been called:

`callDidAnswer:
callDidEstablish:
callDidEnd:


                    
                    
                    callDidEnd(_:)

Default implementation

Tells the delegate that the call ended. This method is invoked on the queue specified via SinchRTC.setCallbackQueue(), which defaults to the main queue.

The call has entered the SinchCall.State.ended state.
