LINETERMCAPS

The LINETERMCAPS structure describes the capabilities of a line's terminal device.

typedef struct linetermcaps_tag {
    DWORD  dwTermDev;
    DWORD  dwTermModes;
    DWORD  dwTermSharing;
} LINETERMCAPS, FAR *LPLINETERMCAPS;
 

Members

dwTermDev

The device type of the terminal, of type LINETERMDEV_. Values are:

LINETERMDEV_PHONE

The terminal is a phone set.

LINETERMDEV_HEADSET

The terminal is a headset.

LINETERMDEV_SPEAKER

The terminal is an external speaker and microphone.

dwTermModes

The terminal modes that the terminal device is able to deal with, of type LINETERMMODE_. Values are:

LINETERMMODE_BUTTONS

Button press events sent from the terminal to the line.

LINETERMMODE_LAMPS

Lamp events sent from the line to the terminal.

LINETERMMODE_DISPLAY

Display information sent from the line to the terminal.

LINETERMMODE_RINGER

Ringer control information sent from the switch to the terminal.

LINETERMMODE_HOOKSWITCH

Hookswitch events sent from the terminal to the line.

LINETERMMODE_MEDIATOLINE

The unidirectional media stream from the terminal to the line associated with a call on the line. Use this value when routing of both unidirectional channels of a call's media stream can be controlled independently.

LINETERMMODE_MEDIAFROMLINE

The unidirectional media stream from the line to the terminal associated with a call on the line. Use this value when routing of both unidirectional channels of a call's media stream can be controlled independently.

LINETERMMODE_MEDIABIDIRECT

The bidirectional media stream associated with a call on the line and the terminal. Use this value when routing of both unidirectional channels of a call's media stream cannot be controlled independently.

dwTermSharing

Specifies how the terminal device is shared between line devices, of type LINETERMSHARING_. Values are:

LINETERMSHARING_PRIVATE

The terminal device is private to a single line device.

LINETERMSHARING_SHAREDEXCL

The terminal device can be used by multiple lines. The last line device to do a TSPI_lineSetTerminal to the terminal for a given terminal mode has exclusive connection to the terminal for that mode.

LINETERMSHARING_SHAREDCONF

The terminal device can be used by multiple lines. The TSPI_lineSetTerminal requests of the various terminals end up merged at the terminal.

Remarks

Not extensible.
