When congestion occurs, the ENUM/DNS server can identify a priority packet without relaying on origin terminal information. An ENUM/DNS packet priority control systemincludes a call control serverthat, upon receiving a connection request from a terminal, determines whether or not the connection request is to be subjected to priority processing based on predetermined determination logic, and generates an ENUM/DNS packet that has a priority flag upon determining that the connection request is to be subjected to priority processing. The ENUM/DNS packet priority control systemalso includes an ENUM/DNS serverthat, upon receiving an ENUM/DNS packet that has the priority flag, determines that the packet is to be subjected to priority processing, and transmits, to the call control server, connection destination information that corresponds to the call destination terminal.
