State Change
The new state is determined by the old state: the state of the
conversation when the local program issued the Confirmed call. The old
state is indicated by the value of the status_received parameter of the
preceding Receive call. Table 3-3, State Changes for the Confirmed Call,
summarizes the possible state changes when return_code is set to
CM_OK.
Other return codes result in no state change.
