TSPIMessage

  • Article

TSPIMessage is an enumeration type that defines the set of additional LINEEVENT and PHONEEVENT functions appearing in TSPI that do not appear in TAPI.

Parameters

TSPI_MESSAGE_BASE

The lowest number in the range of TSPI-specific message values. This value has no meaning by itself, but serves as a base for defining the other values.

LINE_NEWCALL

Specifies that a new, incoming call has arrived and introduces it to TAPI. This must be the first message sent to TAPI for a new incoming call. TAPI returns its opaque identifier for the call as part of its handling of this message.

LINE_CALLDEVSPECIFIC

Specifies that a device-specific event has occurred on a call device.

LINE_CALLDEVSPECIFICFEATURE

Specifies that a device-specific feature event has occurred on a call device.
