MSP_CALL_EVENT_CAUSE enumeration (msp.h)

The MSP_CALL_EVENT_CAUSE constant is returned within the MSP_EVENT_INFO struct by the GetEvent method when MSP_EVENT is ME_CALL_EVENT.

Syntax

typedef enum __MIDL___MIDL_itf_msp_0000_0000_0003 {
  CALL_CAUSE_UNKNOWN = 0,
  CALL_CAUSE_BAD_DEVICE,
  CALL_CAUSE_CONNECT_FAIL,
  CALL_CAUSE_LOCAL_REQUEST,
  CALL_CAUSE_REMOTE_REQUEST,
  CALL_CAUSE_MEDIA_TIMEOUT,
  CALL_CAUSE_MEDIA_RECOVERED,
  CALL_CAUSE_QUALITY_OF_SERVICE
} MSP_CALL_EVENT_CAUSE;

Constants

CALL_CAUSE_UNKNOWN Value: 0 Call event cause is unknown.
CALL_CAUSE_BAD_DEVICE A bad device caused failure, for either STREAM_FAIL or TERMINAL_FAIL.
CALL_CAUSE_CONNECT_FAIL Either connecting the stream failed or connecting the terminal failed. Note that if a terminal cannot be connected to a stream, the application will get a TERMINAL_FAIL event with CMC_CONNECT_FAIL. If this stream failed because the terminal is the only one to use, the application will also get a STREAM_FAIL event with CMC_CONNECT_FAIL.
CALL_CAUSE_LOCAL_REQUEST The event is the result of the application calling a method on the stream.
CALL_CAUSE_REMOTE_REQUEST The event is the result of the remote endpoint's request.
CALL_CAUSE_MEDIA_TIMEOUT The media that carries the stream is temporarily not available.
CALL_CAUSE_MEDIA_RECOVERED The media that carries the stream is back to normal from a temporary denial of service.
CALL_CAUSE_QUALITY_OF_SERVICE
