Optional Methods

– callDidStartRinging:

- (void)callDidStartRinging:(nonnull TVOCall *)call

Parameters

– call:isReconnectingWithError:

Notifies the delegate that a Call starts to reconnect due to network change event.

- (void)call:(nonnull TVOCall *)call isReconnectingWithError:(nonnull NSError *)error

Parameters

call

The TVOCall that is reconnecting.
error

The <NSError> that describes the reconnect reason. This would have one of the two possible values with error codes TVOErrorSignalingConnectionDisconnectedError and TVOErrorMediaConnectionError.

Discussion

Reconnect is triggered when a network change is detected and Call is already in TVOCallStateConnected state. If the call is either in TVOCallStateConnecting or in TVOCallStateRinging when network change happened then the current call will disconnect.
