Abstract

Over the last decade, the technological environment has traveled paths of updates and consolidated the emergence of proposals for new architectures, aimed at integrating the various networks in the world of telecommunications and building synergy between data, voice and image. The NGN networks are based on the exchange of data packets, which permit a flexible and scalable environment where the key factor is the provisioning of new applications, enabling widespread mobility and integration of new services with legacy networks.

To face with this reality, we proposed a solution which is adherent to the functional architecture of NGNs. According to the layered model, at the application layer, we developed five applications that permit the implementation of new services; at the control layer we use the open ip telephony platform asterisk and finally at the transport/access layer, our solution support the following protocols: SIP, IAX, ISDN, R2Digital and SS7 Over IP.

In order to validate our proposed solution, we implemented a Voice Gateway that provides an integration between IP-PSTN networks.
