Abstract:
A device for performing signalling to set up a connection between an originating terminal and a terminating terminal connected to a network using a common signaling message having a plurality of versions of signaling specification, comprising:storage means for storing identification information for identifying the terminals and version information for representing versions of signalling specification that are used at each of the terminals with a correspondence established therebetween;an input port receiving the signalling message from said originating terminal via the network;detecting means for referencing said storage means and detecting versions of the signalling specification that are used at each of said originating and terminating terminals of the received signalling message;message translation means for translating a specified element of the received signalling message on the basis of the versions of the signalling specification that are used at said originating and terminating terminals; andan output port outputting the translated signalling message to said terminating terminal via the network.
