LINE_CALLINFO (TSPI) (Compact 2013)
3/26/2014
This message is sent to the LINEEVENT callback function when the call information about the specified call has changed. TAPI can invoke TSPI_lineGetCallInfo to determine the current call information.

htCall = (HTAPICALL) hCallDevice;
dwMsg = (DWORD) LINE_CALLINFO;
dwParam1 = (DWORD) CallInfoState;
dwParam2 = (DWORD) 0;
dwParam3 = (DWORD) 0;

Remarks
This message is sent to TAPI whenever the event occurs and TAPI has the line open. However, no LINE_CALLINFO messages are sent for a call after the call has entered the idle state.
