A voice messaging service in a VoIP system performs a messaging service for an IP terminal in the VoIP communication system including the IP terminal; an IP controller integrates a VoIP voice mail box function using VoIP technology to provide a voice messaging service to a user of the IP terminal via an IP network. The IP controller function and the voice messaging system function are contained in one piece of equipment, and thus, when a receiving terminal is on the line or does not answer, a system call process status is immediately provided via voice guidance without a separate voice reproducing apparatus, thereby providing a convenient additional service to a terminal user.
