PROBLEM TO BE SOLVED: To provide a display name conversion system that enables a call incoming side terminal device to preferably display a display name from data set in a call control signal.SOLUTION: A display name conversion system 1 comprises: a gateway device 30 that receives a call control signal transmitted from a call origination side terminal device 10A and transmits the call control signal to call incoming side terminal devices 10B, 10C; and a storage unit 41 that stores a conversion policy database 41b in which a call origination network, a call incoming network, and a first conversion policy for converting data set in a plurality of fields included in a call control signal are associated with each other. The gateway device 30 includes a control unit 32 that refers to the conversion policy database 41b on the basis of a call control signal's call origination network and call incoming network to read out a conversion policy corresponding to the call control signal, converts data set in a plurality of fields in the call control signal on the basis of the conversion policy, and transmits the call control signal including the converted data to call incoming side terminal devices 10B, 10C.SELECTED DRAWING: Figure 2 |
