LINEADDRESSSTATE_ Constants

The LINEADDRESSSTATE_ bit-flag constants describe various address status items.

LINEADDRESSSTATE_OTHER

Address-status items other than those listed below have changed. The application should check the current address status to determine which items have changed.

LINEADDRESSSTATE_DEVSPECIFIC

The device-specific item of the address status has changed.

LINEADDRESSSTATE_INUSEZERO

The address has changed to idle (it is not in use by any stations).

LINEADDRESSSTATE_INUSEONE

The address has changed from idle or in use by many bridged stations to being in use by just one station.

LINEADDRESSSTATE_INUSEMANY

The monitored or bridged address has changed from being in use by one station to being in use by more than one station.

LINEADDRESSSTATE_NUMCALLS

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, dwNumOnHoldCalls and dwNumOnHoldPendingCalls in the LINEADDRESSSTATUSGM12S3 structure. The application should check all three of these fields when it receives a LINE_ADDRESSSTATEM6UYG1 (numCalls) message.

LINEADDRESSSTATE_FORWARD

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 status.

LINEADDRESSSTATE_TERMINALS

The terminal settings for the address have changed.

LINEADDRESSSTATE_CAPSCHANGE

Indicates that, due to configuration changes made by the user or other circumstances, one or more of the fields in the LINEADDRESSCAPSPFGP43 structure for the address have changed. The application should use lineGetAddressCapsN4KBZ3 to read the updated structure. If a service provider sends a LINE_ADDRESSSTATEM6UYG1 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_LINEDEVSTATE1F9WSNT 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.
