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.

Syntax

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

Parameters

• htLine
  The TAPI opaque object handle to the line device.

• htCall
  The TAPI opaque object handle to the call device.

• dwMsg
  The value LINE_CALLINFO.

• dwParam1
  Specifies the call information item that has changed. This parameter can be a combination of the LINECALLINFOSTATE_ constants.

• dwParam2

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.
