LINEADDRFEATURE (Windows CE 5.0)

Send Feedback

These constants list the operations that can be invoked on an address.

The following table shows the LINEADDRFEATURE constants.

Value Description
LINEADDRFEATURE_FORWARD = 0x00000001 The address can be forwarded.
LINEADDRFEATURE_MAKECALL = 0x00000002 An outgoing call can be placed on the address.
LINEADDRFEATURE_PICKUP = 0x00000004 A call can be picked up at the address.
LINEADDRFEATURE_PICKUPDIRECT = 0x00000400 The linePickup function can be used to pick up a call on a specific address. TAPI versions 2.0 and later.
LINEADDRFEATURE_PICKUPGROUP = 0x00000200 The linePickup function can be used to pick up a call in the group. TAPI versions 2.0 and later.
LINEADDRFEATURE_PICKUPHELD = 0x00000100 The linePickup function, with a null destination address, can be used to pick up a call that is held on the address. This is normally used only in a bridged-exclusive arrangement. TAPI versions 2.0 and later.
LINEADDRFEATURE_PICKUPWAITING = 0x00000800 The linePickup function, with a null destination address, can be used to pick up a call waiting call. Note that this does not necessarily indicate that a waiting call is actually present, because it is often impossible for a telephony device to automatically detect such a call. It does, however, indicate that the hook-flash function will be invoked to attempt to switch to such a call. TAPI versions 2.0 and later.
LINEADDRFEATURE_SETMEDIACONTROL = 0x00000008 Media control can be set on this address.
LINEADDRFEATURE_SETTERMINAL = 0x00000010 The terminal modes for this address can be set.
LINEADDRFEATURE_SETUPCONF = 0x00000020 A conference call with a NULL initial call can be set up at this address.
LINEADDRFEATURE_UNCOMPLETECALL = 0x00000040 Call completion requests can be canceled at this address.
LINEADDRFEATURE_UNPARK = 0x00000080 Calls can be unparked using this address.
Note   If none of the new modified "PICKUP" bits is set in the dwAddressFeatures member in the LINEADDRESSSTATUS structure but the LINEADDRFEATURE_PICKUP bit is set, then any of the pickup modes may work. The service provider has simply not specified which ones.
LINEADDRFEATURE_FORWARDDND = 0x00001000 The lineForward function (with an empty destination address) can be used to turn on the Do Not Disturb feature on the address. LINEADDRFEATURE_FORWARD will also be set. TAPI versions 2.0 and later.
LINEADDRFEATURE_FORWARDFWD = 0x00002000 The lineForward function can be used to forward calls on the address to other numbers. LINEADDRFEATURE_FORWARD will also be set.
Note   If neither of the new modified "FORWARD" bits is set in the dwAddressFeatures member in LINEADDRESSSTATUS but the LINEADDRFEATURE_FORWARD bit is set, then any of the forward modes may work; the service provider has simply not specified which ones. TAPI versions 2.0 and later.

Remarks

These constants cannot be extended. All 32 bits are reserved.

These constants are used both in the LINEADDRESSCAPS (returned by lineGetAddressCaps) and in the LINEADDRESSSTATUS (returned by lineGetAddressStatus) structures. LINEADDRESSCAPS reports the availability of the address features by the service provider (mainly the switch) for a given address. An application would make this determination when it initializes. The LINEADDRESSSTATUS structure reports, for a given address, which address features can actually be invoked while the address is in the current state. An application would make this determination dynamically after address-state changes, typically caused by call-related activities on the address.

Requirements

OS Versions: Windows CE 3.0 and later.
Header: Tapi.h.
