Node information in which a transmission destination IP address for the Megaco signal and a device number included in the SIGTRAN signal are correlated is stored in a node information storage unit 24. A SIP signal and the Megaco signal are tied using a connection IP address, and the Megaco signal and the SIGTRAN signal are tied using the line information and the node information. The SIP signal and the SIGTRAN signal necessary for securing a speech path can thereby be tied via the Megaco signal even when corresponding information identifiable as the same call is nonexistent between the SIP signal and the SIGTRAN signal.
