Abstract
A gateway device is connected between a switched-circuit communication network and at least two VoIP network domains, each domain having a packet-based signaling controller. The gateway device transfers to each of the signaling controllers a registration request message so that the gateway device is simultaneously registered in the at least two VoIP network domains as a VoIP end point.
Claims13
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;
- and
- 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.
A gateway device for communication between a switched-circuit communication network and Voice over Internet Protocol network domains, each Voice over Internet Protocol network domain having a packet-based signaling controller, comprising:
- interfaces coupled to the switched-circuit communication network and the Voice over Internet Protocol network domains;
- and
- a registration device, coupled to said interfaces, to transfer a registration request message to the packet-based signaling controller in each of the Voice over Internet Protocol network domains for simultaneous registration of the gateway device in each of the Voice over Internet Protocol network domains as a Voice over Internet Protocol end point.
A communication system, comprising
- a switched-circuit communication network;
- Voice over Internet Protocol network domains, each Voice over Internet Protocol network domain having a packet-based signaling controller;
- and
- a gateway device, including
- interfaces coupled to said switched-circuit communication network and said Voice over Internet Protocol network domains;
- and
- a registration device, coupled to said interfaces, to transfer a registration request message to the packet-based signaling controller in each of said Voice over Internet Protocol network domains for simultaneous registration of the gateway device in each of said Voice over Internet Protocol network domains as a Voice over Internet Protocol end point.
