ABSTRACT:
A conventional voice mail system is disadvantageous in that it is low in expandability, reliability, processing capacity at the busiest time and maintainability of the system and it is difficult to cope with trouble when it occurs or when a new service is to be introduced. A control system for a voice mail system of the present invention includes switching units 2 for connecting voice mail system 100 and switching systems 1 path connected to subscribers 6 via lines, voice data management units 3 for producing and sending voice data guidance, voice data storage units 5 for storing and reproducing voice data, and service control unit 8 connected to switching systems 1 via signaling network 7 for controlling entire voice mail system 100. Service control unit 8 controls the other components 2 to 5 of voice mail system 100 to receive and execute an instruction of a service request from any subscriber 6, and selects, when a component of an arbitrary kind of voice mail system 100 is not in an available condition, another component of the same kind in place of the unavailable component.
