Disclosed is a method and apparatus for simplifying the design effort of creating and debugging a JTAPI (JAVA TM Telephony application programming interface) implementation and the resulting apparatus. The JTAPI is constructed in a multilayer fashion. In one embodiment, a generic portion or layer comprises a large percentage of the required source code and includes a standardized API to an adapter layer which typically comprises a minority portion of total required code for the interface. The generic layer, provides services and mechanisms needed by all JTAPI compliant applications. Its job is to maintain the call model visible to applications through the JTAPI interface, and to dispatch application events upon state changes. The generic layer passes call control requests to the lower level adapter layer, which is responsible for executing the low-level call control requests and reporting back to the generic layer the changes in the state of the telephony hardware. Many of the classes of objects in the generic layer can be created in subclasses of the adapter layer.
