Abstract:
1. A network service provider system comprising: a first coding unit that is communicatively coupled to a first endpoint via a circuit-switching telephone network and communicatively coupled to a first packet-switching network; a first signaling unit that is communicatively coupled to the first coding unit, and to a second signaling unit via a second packet-switching network; a second coding unit communicatively coupled to a second endpoint and to the second signaling unit; and a first memory of the first signaling unit and a second memory in the second signaling unit having one or more sequences of instructions stored therein, which instructions, when executed by the first signaling unit and the second signaling unit, respectively, cause the first signaling unit and second signaling unit to process call signaling information separately from voice information, by performing the steps of in response to receiving, from the circuit-switching telephone network,
