Abstract

Recently, the field of IP Telephony has been experienced considerable evolution through the specification of new protocols and introduction of products implementing these protocols. We visualize IP Telephony evolving to soon offer multiservices encompassing not only voice, but also data, video and multimedia. While the progress has focused on refining protocols and architectures, very little attention has been given to business models for offering these services. This paper introduces the concept of a Service Zone, which from a service provider/network operator perspective fits within the operator's administrative domain, but is viewed as an independent zone with its own management and services, requiring minimal integration with the core network services. Besides its own management, the Enhanced Services Zone may also provide provisioning and maintenance features needed to provide the customer services and availability that subscribers expect from a telephony service providers. The platform must provide reliable service over time, be scalable to meet increased capacity demands, and be upgradeable to incorporate advanced services and features as they become available. Signaling flows are illustrated using SIP and H.323.
