Abstract
The present invention is the communication system that the communication connection control between the terminals is performed, in the IP transfer network forming the closed network, by using the IP communication record. Further, the present invention relates to the communication system to perform the communication connection control between the terminals by obtaining the IP address of the server which manages the communication connection control of the destination terminal based on the telephone number or the host name of the destination terminal.
