The following table shows the TAPI constants with a description of the purpose of each.

Programming elements	Description
LINEADDRCAPFLAGS	These bit-flag constants are used in the dwAddrCapFlags member of the LINEADDRESSCAPS data structure to describe various Boolean address capabilities.
LINEADDRESSMODE	These bit-flag constants describe various ways of identifying an address on a line device.
LINEADDRESSSHARING	These bit-flag constants describe various ways an address can be shared between lines.
LINEADDRESSSTATE	These bit-flag constants describe various address status items.
LINEADDRESSTYPE	The address type identifies address format, such as standard phone number or e-mail address.
LINEADDRFEATURE	These constants list the operations that can be invoked on an address.
LINEANSWERMODE	These bit-flag constants describe how an existing active call on a line device is affected by answering another offering call on the same line.
LINEBEARERMODE	These bit-flag constants describe different bearer modes of a call.
LINEBUSYMODE	These bit-flag constants describe different busy signals that the switch or network can generate.
LINECALLCOMPLCOND	These bit-flag constants describe the conditions under which a call can be completed.
LINECALLCOMPLMODE	These bit-flag constants describe different ways in which a call can be completed.
LINECALLFEATURE	These constants indicate operations that can be invoked for a given address or call.
LINECALLFEATURE2	These bit-flag constants describe the supplemental features available for conferencing, transferring, and parking calls.
LINECALLINFOSTATE	These bit-flag constants describe various call information items about which an application can be notified in the LINE_CALLINFO message.
LINECALLORIGIN	These bit-flag constants describe the origin of a call.
LINECALLPARAMFLAGS	These constants describe various status flags about a call.
LINECALLPARTYID	These bit-flag constants describe the nature of the information available about the parties involved in a call.
LINECALLPRIVILEGE	These bit-flag constants describe the kinds of access rights or privileges an application with a call handle may have to the corresponding call.
LINECALLREASON	These bit-flag constants describe the reason for a call.
LINECALLSELECT	These bit-flag constants describe which calls are to be selected.
LINECALLSTATE	These bit-flag constants describe the call states a call can be in.
LINECALLTREATMENT	These constants describe treatments for calls that are unanswered or on hold. Except for basic parameter validation, call treatment is a straight pass-through by TAPI to the service provider.
LINECONNECTEDMODE	These bit-flag constants describe different substates of a connected call.
LINEDEVCAPFLAGS	These bit-flag constants are a collection of Booleans describing various line device capabilities.
LINEDEVSTATE	These bit-flag constants describe various line status events.
LINEDEVSTATUSFLAGS	These bit-flag constants describe a collection of Boolean line device status items.
LINEDIALTONEMODE	These bit-flag constants describe different types of dial tones. A special dial tone typically carries a special meaning (as with message waiting).
LINEDIGITMODE	These constants describe different types of inband digit generation.
LINEDISCONNECTMODE	These bit-flag constants describe different reasons for a remote disconnect request.
LINEERR	The following list contains the list error codes that TAPI can return when invoking operations on lines, addresses, or calls.
LINEFEATURE	These constants list the operations that can be invoked on a line using this API.
LINEFORWARDMODE	These bit-flag constants describe the conditions under which calls to an address can be forwarded.
LINEGATHERTERM	These bit-flag constants describe the conditions under which buffered digit gathering is terminated.
LINEGENERATETERM	These bit-flag constants describe the conditions under which digit or tone generation is terminated.
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.
LINESPECIALINFO	These bit-flag constants describes special information signals that the network can use to report various reporting and network observation operations.
LINETERMDEV	These bit-flag constants describe different types of terminal devices.
LINETERMMODE	These bit-flag constants describe different types of events on a phone line that can be routed to a terminal device.
LINETERMSHARING	These bit-flag constants describe different ways in which a terminal can be shared between line devices, addresses, or calls.
LINETOLLLISTOPTION	These bit-flag constants describe options for manipulating a toll list.
LINETONEMODE	These constants describe different selections that are used when generating line tones.
LINETRANSFERMODE	These bit-flag constants describe different ways of resolving call transfer requests.
LINETRANSLATEOPTION	These bit-flag constant describes an option used by address translation.
LINETRANSLATERESULT	These bit-flag constants describe various results of an address translation.
PHONEBUTTONFUNCTION	These scalar constants describe the functions commonly assigned to buttons on telephone sets.
PHONEBUTTONMODE	These bit-flag constants describe the button classes.
PHONEBUTTONSTATE	These bit-flag constants describe the button's positions.
PHONEERR	The PHONEERR constants consist of a list of error codes that the implementation can return when invoking operations on phone devices.
PHONEFEATURE	These constants list the operations that can be invoked on a phone using TAPI.
PHONEHOOKSWITCHDEV	These bit-flag constants describe various audio I/O devices each with its own hookswitch controllable from the computer.
