Abstract
When a call is set between a first line switching network of a call-out side and a second line switching network of a call-in side, a first gateway, if receives a call setting message from the first line switching network, transmits a inquiry message to at least one of second gateway. Each of second gateway from which received the inquiry message transmits a response message to the first gateway when a second gateway itself can communicate a call setting message to the second line switching network. Thereafter, the first gateway selects a second gateway for transmitting the call setting message within the second gateways to which transmitted the response message, and transmits the call setting message to the selected second gateway.
