              0601 Power Down when making a call
              - The Audio Manager never received a CNF back from the SEEM and thus never
                handled any other tone request primitives causing a power down. Do not
                handle completion events from the DSP if the state of the AM is ABORT or
                DO_NOTHING. A race condition exists between canceling an event and
                receiving a completion event from the DSP. If the completion event is
                handled after the event has been canceled the SEEM task may not send a CNF.
