Given the convergence of the PSTN and IP-based networks, it would be advant
ageous to transparently support access to the existing installed base of in
telligent network services from packet endpoints, while simultaneously prov
iding newer, more advanced services to said endpoints from within the IN in
frastructure. In this article we describe the INSeCT (IN Services for Conve
rged [Internet] Telephony) prototype, aimed at achieving these very goals i
n networks using H.323. The early sections briefly present background mater
ial on VoIP and IN, while the rest of the article focuses on the prototype
implementation.
