The following table shows the TSPI line device functions with a description of the purpose of each.

Programming element	Description
TSPI_lineAccept	Accepts the specified offered call. Optionally, this function can send the specified user-user information to the calling party.
TSPI_lineAddToConference	Adds the call that is specified by the hdConsultCall parameter to the conference call that is specified by the hdConfCall parameter.
TSPI_lineAnswer	Answers the specified offering call.
TSPI_lineBlindTransfer	Performs a blind or single-step transfer of the specified call to the specified destination address.
TSPI_lineClose	Closes the specified open line device after completing or aborting every outstanding call and asynchronous operation on the device.
TSPI_lineCloseCall	Deallocates the call after completing or aborting every outstanding asynchronous operation on the call.
TSPI_lineCompleteCall	This function is not called by TAPI.
TSPI_lineCompleteTransfer	Completes the transfer of the specified call to the party that is connected in the consultation call.
TSPI_lineConditionalMediaDetection	Is invoked by TAPI whenever a client application uses the LINEMAPPER value as the dwDeviceID parameter in a lineOpen function, to request that lines be scanned to find one that supports the desired media modes and call parameters.
TSPI_lineConfigDialogEdit	Causes the provider of the specified line device to display a modal dialog box as a child window of the hwndOwner parameter, to allow the user to configure parameters that are related to the line device.
TSPI_lineDevSpecific	Is used as a general extension mechanism to enable service providers to provide access to features that are not described in other operations. The meanings of the extensions are device-specific, and the application must be fully aware of these extensions to take advantage of them.
TSPI_lineDevSpecificFeature	This function is not called by TAPI.
TSPI_lineDial	Dials the specified dialable number on the specified call.
TSPI_lineDrop	Drops or disconnects the specified call. Optionally, user-user information can be transmitted as part of the disconnect of the call. This function can be called by the application at any time.
TSPI_lineDropNoOwner	This function is not called by TAPI.
TSPI_lineDropOnClose	This function is not called by TAPI.
TSPI_lineForward	Forwards calls that are destined for the specified address on the specified line, according to the specified forwarding instructions.
TSPI_lineGenerateDigits	Initiates the generation of the specified digits on the specified call as inband tones by using the specified signaling mode.
TSPI_lineGenerateTone	Generates the specified tone inband over the specified call.
TSPI_lineGetAddressCaps	Queries the specified address on the specified line device to determine its telephony capabilities.
TSPI_lineGetAddressID	Returns the address identifier that is associated with the address that is assigned to the specified line device.
TSPI_lineGetAddressStatus	Queries the specified address for its current status.
TSPI_lineGetCallAddressID	Retrieves the address identifier for the indicated call.
TSPI_lineGetCallInfo	Returns detailed information about the specified call.
TSPI_lineGetCallStatus	Returns the current status of the specified call.
TSPI_lineGetDevCaps	Queries a specified line device to determine its telephony capabilities. The returned information is valid for every address on the line device.
TSPI_lineGetDevConfig	Returns a data-structure object, the contents of which are specific to the line (service provider) and device class, giving the current configuration of a device that is associated one-to-one with the line device.
TSPI_lineGetExtensionID	Returns the extension identifier that the service provider supports for the indicated line device.
TSPI_lineGetIcon	Retrieves a service line device-specific icon to display to the user.
TSPI_lineGetID	Returns a device identifier for the specified device class that is associated with the selected line, address, or call.
TSPI_lineGetLineDevStatus	Queries the specified open line device for its current status. The information that is returned is global to every address on the line.
TSPI_lineGetNumAddressIDs	Retrieves the number of address identifiers that are supported on the indicated line.
TSPI_lineHold	Places the specified call on hold.
TSPI_lineMakeCall	Places a call on the specified line to the specified destination address.
TSPI_lineMonitorDigits	Enables and disables the unbuffered detection of digits that are received on the call.
TSPI_lineMonitorMedia	Enables and disables the detection of media modes on the specified call.
TSPI_lineMonitorTones	This function is not called by TAPI.
TSPI_lineNegotiateExtVersion	Returns the highest extension version number for this device under which the service provider can operate, given the range of possible extension versions.
TSPI_lineNegotiateTSPIVersion	Returns the highest TSPI version for this device under which the service provider can operate, given the range of possible TSPI versions.
TSPI_lineOpen	Opens the line device whose device identifier is given, and returns the handle of the service provider for the device.
TSPI_linePark	This function is not called by TAPI.
TSPI_linePickup	Picks up a call alerting at the specified destination address, and returns a call handle for the picked-up call.
TSPI_linePrepareAddToConference	Prepares an existing conference call for the addition of another party.
TSPI_lineRedirect	Redirects the specified offering call to the specified destination address.
TSPI_lineReleaseUserUserInfo	Informs the service provider that the user-user information that is contained in the LINECALLINFO structure has been processed, and that subsequently received user-user information now can be written into that structure.
TSPI_lineRemoveFromConference	Removes the specified call from the conference call to which it currently belongs. The remaining calls in the conference call are unaffected.
TSPI_lineSecureCall	This function is not called by TAPI.
TSPI_lineSelectExtVersion	This function is not supported in Windows Embedded CE.
TSPI_lineSendUserUserInfo	Sends user-user information to the remote party on the specified call.
TSPI_lineSetAppSpecific	This function is not called by TAPI.
TSPI_lineSetCallParams	Sets certain parameters for an existing call.
TSPI_lineSetCurrentLocation	Is obsolete; TAPI called this function when the user (by using the Dialing Properties dialog box) or an application (by using the lineSetCurrentLocation function) changed the address translation location.
TSPI_lineSetDefaultMediaDetection	Tells the service provider the new set of media modes to detect for the indicated line (replacing any previous set).
TSPI_lineSetDevConfig	Sets the configuration of the line device.
TSPI_lineSetMediaControl	This function is not called by TAPI.
TSPI_lineSetMediaMode	Changes the media of the call as stored in the LINECALLINFO structure of the call.
TSPI_lineSetStatusMessages	Enables TAPI to specify the notification messages that the service provider should generate for events that are related to status changes for the specified line or any of its addresses.
TSPI_lineSetTerminal	Enables TAPI to specify the terminal to which information that is related to the specified line, address, or call should be routed.
TSPI_lineSetupConference	Sets up a conference call for the addition of the third party.
TSPI_lineSetupTransfer	Initiates a transfer of the call specified by the hdCall function.
TSPI_lineSwapHold	Swaps the specified active call with the specified call on consultation hold.
TSPI_lineUncompleteCall	This function is not called by TAPI.
TSPI_lineUnhold	Retrieves the specified held call.
TSPI_lineUnpark	This function is not called by TAPI.
