To send a voice message during a speech or during absence even when a general telephone network subscriber does not possess an automatic reply telephone set by storing a voice message to an intelligence information service system (IP).

When a local exchange LE recognizes an automatic telephone reply service request, an intelligent network service exchange (SSP) 104 triggers a service logic and makes a service request to a service controller (SCP) 101 and the IP 105 is used to make routing. The IP 105 is controlled by the SCP 101 through the SSP 104, serves a special resource to the service user and collects or stores input data from the service user. The SCP 101 has the service logic and data required for the service to control and process the automatic telephone reply service. A service management system(SMS) 102 revises and manages data and logic required to conduct the service. A signal repeater (STP) 103 sends an SSNo.7 message between the SCP 101 and the SSP 104.
