IN services for converged (Internet) telephony

Given the convergence of the PSTN and IP-based networks, it would be advantageous to transparently support access to the existing installed base of intelligent network services from packet endpoints, while simultaneously providing newer, more advanced services to said endpoints from within the IN infrastructure. In this article we describe the INSeCT (IN Services for Converged [Internet] Telephony) prototype, aimed at achieving these very goals in networks using H.323. It presents background material on VoIP and IN, then focuses on the prototype implementation.
