The present invention relates to a voice mail system (VMS), and more particularly, to a system and method for unifying multiple connection ports of a voice mail system. A system according to the present invention includes an external input/output controller (EIOC) provided between a VMS having a plurality of boards that perform the same function and a plurality of external servers. The EIOC is adapted to provide an unified network connection point between the plurality of boards and the plurality of external servers by routing a message transferred from any one of the plurality of boards to any one of the external servers. The EIOC is also configured to route a message transferred from any one of the plurality of external servers to a corresponding board of the VMS. The stability of such a system is increased by making external servers (IP networks) regard the VMS as a single network connection point. In addition, since the EIOC allows external servers to be connected to the VMS, and performs a routing function, it can detect an intrusion of an inaccessible external server, and maintain the security for the VMS.
