Method Detail

onConnectFailure

void onConnectFailure(Call call,
                      CallException callException)

The call failed to connect.

Calls that fail to connect will result in onConnectFailure(Call, CallException) and always return a CallException providing more information about what failure occurred.

Parameters:

call - An object model representing a call that failed to connect.

callException - CallException that describes why the connect failed.

onRinging

void onRinging(Call call)

Emitted once before the onConnected(Call) callback. If answerOnBridge is true, this represents the callee being alerted of a call. The Call.getSid() is now available.

Parameters:

call - An object model representing a call.

onConnected

void onConnected(Call call)

The call has connected.

Parameters:

call - An object model representing a call.

onReconnecting

void onReconnecting(Call call,
                    CallException callException)

The call starts reconnecting. Reconnect is triggered when a network change is detected and Call is already in Call.State.CONNECTED state. If the call is in Call.State.CONNECTING or in Call.State.RINGING when network change happened the SDK will continue attempting to connect, but a reconnect event will not be raised.

Parameters:

call - An object model representing a call.

callException - CallException that describes the reconnect reason. This would have one of the two possible values with error codes 53001 "Signaling connection disconnected" and 53405 "Media connection failed".

onReconnected

void onReconnected(Call call)

The call is reconnected.

Parameters:

call - An object model representing a call.

onDisconnected

void onDisconnected(Call call,
                    CallException callException)

The call was disconnected.

A call can be disconnected for the following reasons:

• A user calls `disconnect()` on the `Call` object.
• The other party disconnects or terminates the call.
• An error occurs on the client or the server that terminates the call.

If the call ends due to an error the `CallException` is non-null. If the call ends normally `CallException` is null.

Parameters:

call - An object model representing a call.

callException - CallException that caused the call to disconnect.
