dwRedirectingIDFlags

These fields describe the various kinds of party identifier information that can be provided for calls on this address. This member uses the following LINECALLPARTYID_ constants:

LINECALLPARTYID_BLOCKED: Caller identifier information for the call is blocked by the caller, but would otherwise be available.
LINECALLPARTYID_OUTOFAREA: Caller identifier information for the call is not available as it is not propagated all the way by the network.
LINECALLPARTYID_NAME: The caller identifier information for the call is the caller's name (from a table maintained inside the switch). It is provided in the caller identifier name variably sized field.

dwCallStates

The various call states that can be reported for calls on this address. This member uses the following LINECALLSTATE_ constants:

LINECALLSTATE_IDLE: The call is idle; no call actually exists.
LINECALLSTATE_OFFERING: The call is being offered to the station, signaling the arrival of a new call. In some environments, a call in the offering state does not automatically alert the user; alerting is done by the switch instructing the line to ring. It does not affect any call states.
LINECALLSTATE_ACCEPTED: The call was offering and has been accepted. This indicates to other (monitoring) applications that the current owner application has claimed responsibility for answering the call. In ISDN, this also initiates alerting to both parties.
LINECALLSTATE_DIALTONE: The call is receiving a dial tone from the switch, which means that the switch is ready to receive a dialed number.
LINECALLSTATE_DIALING: Destination address information (a phone number) is being sent to the switch over the call. Note that the operation TSPI_lineGenerateDigits does not place the line into the dialing state.
LINECALLSTATE_RINGBACK: The call is receiving ringback from the called address. Ringback indicates that the other station has been reached and is being alerted.
LINECALLSTATE_BUSY: The call is receiving a busy tone. Busy tone indicates that the call cannot be completed because either a circuit (trunk) or the remote party's station is in use.
LINECALLSTATE_SPECIALINFO: Special information is sent by the network. Special information is typically sent when the destination cannot be reached.
LINECALLSTATE_CONNECTED: The call has been established, the connection is made. Information is able to flow over the call between the originating address and the destination address.
LINECALLSTATE_PROCEEDING: Dialing has completed and the call is proceeding through the switch or telephone network.
LINECALLSTATE_ONHOLD: The call is on hold by the switch.
LINECALLSTATE_CONFERENCED: The call is currently a member of a multiparty conference call.
LINECALLSTATE_ONHOLDPENDCONF: The call is currently on hold while it is being added to a conference.
LINECALLSTATE_ONHOLDPENDTRANSFER: The call is currently on hold awaiting transfer to another number.
LINECALLSTATE_DISCONNECTED: The remote party has disconnected from the call.
LINECALLSTATE_UNKNOWN: The state of the call is not known. This can be due to limitations of the call progress detection implementation.

LINEBUSYMODE_UNAVAIL: The busy signal's specific mode is unavailable and cannot become known.

dwSpecialInfo

LINESPECIALINFO_CUSTIRREG: This special information tone precedes a vacant number, AIS, Centrex number change and nonworking station, access code not dialed or dialed in error, or manual intercept operator message (customer irregularity category).
LINESPECIALINFO_REORDER: This special information tone precedes a reorder announcement (equipment irregularity category).
LINESPECIALINFO_UNKNOWN: Specifics about the special information tone are currently unknown but can become known later.
LINESPECIALINFO_UNAVAIL: Specifics about the special information tone are unavailable, and cannot become known.

LINEADDRCAPFLAGS_FWDSTATUSVALID: Specify whether the forwarding status in the LINEADDRESSSTATUS structure for this address is valid.
LINEADDRCAPFLAGS_FWDINTEXTADDR: Specify whether internal and external calls can be forwarded to different forwarding addresses. This flag is only meaningful if forwarding of internal and external calls can be controlled separately. This flag is TRUE if internal and external calls can be forwarded to different destination addresses; otherwise, FALSE.

dwCallFeatures

The switching capabilities or features available for all calls on this address, of type LINECALLFEATURE. Invoking a supported feature requires the call to be in the proper state and the underlying line device to be opened in a compatible mode. A zero in a bit position indicates that the corresponding feature is never available; a one indicates that the corresponding feature may be available if the application has the right privileges to the call, and the call is in the appropriate state for the operation to be meaningful.
