VoIP - IP Telephony White Papers

A Step-by-Step Migration Scenario From PSTN to NGN

Overview This paper presents a step-by-step migration scenario from a TDM-based Public Switched Telephone Network (PSTN) to a packet-based Next Generation Network (NGN). From an economic point of view, it identifies the drivers and benefits for an established carrier to consolidate its current network and to migrate to an NGN. From a technology point of view, the paper focuses on the role of call/session signaling protocols, and the opportunity to deploy services and applications through open interfaces.
