ABSTRACT:
A signalling gateway for transmitting messages between a first network and a second network, where the first network comprises an SS7 network and the second network comprises an IP network, the second network comprising a plurality of application servers, the signalling gateway being operable to store SS7 characteristic information corresponding to the application servers, the signalling gateway being operable to receive a message via the first network, the message comprising destination information and origin information identifying a calling entity, read the destination information and identify an application server in accordance with the destination information, transmit the message to the application server, the message comprising the destination information and origin information, receive a response from the application server, the response comprising a destination identifier corresponding to the origin information and an origin identifier corresponding to the destination information, substitute the SS7 characteristic information in the response for the origin identifier, and forward the response via the first network to the calling entity.
