Or, in the case of media-mode handoff, no application has opened the same line with the LINECALLPRIVILEGE_OWNER bit in the dwPrivileges parameter of lineOpen and with the media type specified in the dwMediaMode parameter having been specified in the dwMediaModes parameter of lineOpen.
LINEERR_TARGETSELF = 0x8000004F	The application invoking this operation is the target of the indirect handoff. That is, TAPI has determined that the calling application is also the highest priority application for the given media type.

Remarks

The values 0xC0000000 through 0xFFFFFFFF are available for device-specific extensions. The values 0x80000000 through 0xBFFFFFFF are reserved, while 0x00000000 through 0x7FFFFFFF are used as request identifiers.

If an application gets an error return that it does not specifically handle, such as an error defined by a device-specific extension, it should treat the error as an error that occurred for an unspecified reason of type LINEERR_OPERATIONFAILED.

When invoking the LINEERR constants, which are new with TAPI 3.0, the Tapierr.mc file must be updated with new messages.
