The LINEADDRESSSTATE_ bit-flag constants describe various address status
Address-status items other than those listed below have changed. The
application should check the current address status to determine which items have
The device-specific item of the address status has changed.
The address has changed to idle (it is not in use by any stations).
The address has changed from idle or in use by many bridged stations to being
in use by just one station.
The monitored or bridged address has changed from being in use by one station
to being in use by more than one station.
The number of calls on the address has changed. This is the result of events
such as a new inbound call, an outbound call on the address, or a call changing
its hold status. This flag covers changes in any of the fields dwNumActiveCalls
in the LINEADDRESSSTATUS
structure. The application should check all three of these fields when it
receives a LINE_ADDRESSSTATE
The forwarding status of the address has changed, including possibly the
number of rings for determining a no-answer condition. The application should check
the address status to determine details about the address's current forwarding
The terminal settings for the address have changed.
Indicates that, due to configuration changes made by the user or other
circumstances, one or more of the fields in the LINEADDRESSCAPS
structure for the address have changed. The application should use lineGetAddressCaps
to read the updated structure. If a service provider sends a LINE_ADDRESSSTATE
message containing this value to TAPI, TAPI will pass it along to
applications which have negotiated TAPI version 0x00010004 or above; applications
negotiating a previous API version will receive LINE_LINEDEVSTATE
messages specifying LINEDEVSTATE_REINIT, requiring them to shutdown and
reinitialize their connection to TAPI to obtain the updated information.
No extensibility. All 32 bits are reserved.
An application is notified about changes to these status items in the
LINE_ADDRESSSTATE message. The address's device capabilities indicate which address
state changes can possibly be reported for this address.
