Property Value

Type: TapiCallFeatures
TapiCallFeatures describing switching capabilities or features available for all calls on this address.

This property represents the call-related features that may possibly be available on the address (static availability as opposed to dynamic availability). 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. This member allows an application to discover which call features can be (and which can never be) supported by the address.
