Parameter Flags

Parameter flags supply information on a variety of status flags concerning a communications session, such as whether caller identification should be blocked. See LINECALLPARAMFLAGS_ Constants for a list of flags defined by TAPI.

Not all service providers support use of this information.

TAPI 2.x: See lineGetCallInfo (dwCallParamFlags member of lpCallInfo).

TAPI 3.x: See ITCallInfo::get_CallInfoLong (CIL_CALLPARAMSFLAGS member of CALLINFO_LONG).
