    摘要: The VoIP gateway 50a in accordance with the present invention serves to send a connection request to either the IP network 2 or the PSTN 1 on the basis of the information stored in the VOIP gateway 50a and the destination telephone number contained in the connection request as sent from the telephone terminal 70a. Also, even if a connection request is decided to be sent to the IP network 2, the VOIP gateway 50a sends the connection request to the PSTN 1 when the IP network state judgment unit 56 judges that the communication through the IP network 2 is impossible. Furthermore, if a destination telephone number includes predetermined identification information, the VOIP gateway 50a can forcibly send the connection request to the PSTN 1.
