Abstract:
1. A method for communication between a switched-circuit network and at least two Voice over Internet Protocol network domains, each featuring packet-based signaling control, comprising: transferring registration request messages from a gateway device, connected between the switched-circuit communication network and the Voice over Internet Protocol network domains, to a signaling controller in each of the Voice over Internet Protocol network domains, respectively; simultaneously registering the gateway device in the Voice over Internet Protocol network domains as a Voice over Internet Protocol termination point in response to the registration request messages; and receiving, at the gateway device from the switched-circuit communication network after said registering, a circuit-oriented connection setup message with destination address information identifying the communication destination; evaluating at the gateway device the destination address information; and determining at the gateway device, based on the destination address information, a choice relating to further connection setup between the Voice over Internet Protocol network domains.
