6.3.6 PSTNCallControl::Answering State

The application waits for a GCEV_ANSWERED event. Upon receipt of the event, the state transitions to Connected.

If the application receives a GCEV_DISCONNECTED or GCEV_TASKFAIL event, it calls getResultValue( ) to get the disconnect reason and then calls dropCall( ). If the dropCall( ) function fails, the application calls resetLineDevice( ) to reset the line device and the state transitions to Init. Otherwise, the state transitions to Dropping.

If the application receives a USR_DISCONNECT event it retrieves the DropReason from the EventData and calls dropCall( ). If the dropCall( ) function fails, the application calls resetLineDevice( ) to reset the line device and the state transitions to Init. Otherwise, the state transitions to Dropping.
