| LINEINITIALIZEEXOPTION | These ordinal constants specify which event notification mechanism to use when initializing a session. |
| LINELOCATIONOPTION | These constants define values used in the dwOptions member of the LINELOCATIONENTRY structure returned as part of the LINETRANSLATECAPS structure returned by lineGetTranslateCaps. |
| LINEMEDIACONTROL | These bit-flag constants describe a set of generic operations on media streams. |
| LINEMEDIAMODE | These constants describe media types (or modes) of a communications session or call. |
| LINEOFFERINGMODE | These bit-flag constants for TAPI versions 1.4 and later, describe different substates of an offering call. |
| LINEOPENOPTION | These constants describe the available options for opening a line. |
| LINEPARKMODE | These bit-flag constants describe different ways of parking calls. |
| LINEREMOVEFROMCONF | These scalar constants describe how parties participating in a conference call can be removed from a conference call. |
| LINEROAMMODE | These bit-flag constants describe the roaming status of a line device. |
