Abstract: Methods and apparatus are disclosed for automatically generating a data handling framework to manage public data structures. A customizable framework is generated based on one or more parameters of the public data structures to be managed. A data model architecture is disclosed that features a data model for wrapping public data structures, handling the public data structures and various elements of the public data structures, including validation capabilities for the data. The data model architecture includes an automatically generated module, referred to as the data-handling framework. The data-handling framework wraps public data structures and provides, for example, creation, accessor and modification functions. In addition, the data-handling framework provides mechanisms for tracking changes and a skeleton framework for validation routines.

Abstract: A administration tool is disclosed for administering a switch, such as a Private Branch Exchange (PBX) switch that optionally provides an IP Telephony feature. Data objects associated with one or more endpoints of the switch are processed, wherein at least one of the data objects inherits an intelligent property from another data object based on one more endpoint-specific criteria. The inheritance may occur as the result of an application of a predefined template to a data object. The processing of configuration data may be performed offline from the switch, using one or more classes of service that are stored remote from the switch. Changes to configuration data are propagated to affected data objects (e.g., those objects referenced by a changed object). The data objects may be imported from an external data source. Another aspect of the invention automatically creates one or more hunt groups populated with appropriate users during an import process.

Abstract: Methods and apparatus are provided for validating configuration data in a switch. An error is detected if the configuration data fails to comply with one or more rules; and a user is presented with an interface that allows the user to correct the error. The rules may include one or more syntactic rules or conflict rules (or both). In the case of a simple error, the user is presented with an error indication with a smart error link. In the case of a conflict error, the user is presented with an error indication that identifies the conflicting endpoints and optionally allows the user to correct at least one conflicting endpoint. The configuration data is revalidated after a change is made by a user. Changes are propagated to affected data objects. A number of error types may be automatically updated.
