| Comments | This message is used by a service provider in conjunction with the TSPI_lineDevSpecificFeature function. Its meaning is device specific |
| The TAPI DLL sends the LINE_DEVSPECIFICFEATURE message to applications in response to receiving this message from a Service Provider. The htLine is translated to the appropriate hLine as the hDevice parameter at the TAPI level. The dwParam1, dwParam2, and dwParam3 paramters are passed through unmodified. | |
| Comparison | This differs from the corresponding message at the TAPI level in that it is used only to report device-specific feature events occurring on a line or address. At the TSPI level, the LINE_CALLDEVSPECIFICFEATURE is used to report device-specific feature events happening on a call. |
