AbstractA voice-mail system (10) is assembled from one (100) or more (100-102) programmable multi-function boards all of which are interchangeable and physically identical. The voice-mail system functionality is distributed, on a function-by-function basis, among the modules of the system, each one of which can perform any one or more, or all, of the requisite functions. One of the modules is designated a master module (100). Under program control, it specifies to all the modules which functions that module is to perform. Under program control, each of the modules responds to the specification by loading itself with requisite programs whose execution will result in the performance of the specified functions. No separate and distinct resource-management module is needed.
