Gateways are required so that service provider can extend the reach of their applications across multi-protocol networks including SS7, IP, cable 2.0, and wireless as well as protocols such as SIP, and standards for IMS. In addition, gateways make it easier to expand the set of applications in the various incompatible networks and for a way to interconnect networks of different types.

This study is INSIGHT's fourth in a continuing series that addresses the business potential and market trends for gateways. The study examines seven types of gateways, as well as session border controllers and media servers, all of which are driven by similar market demand. The study forecasts unit demand and revenue by geographic region for SIP gateways, enterprise gateways, enhanced services gateways, wireless gateways, wholesale gateways, hybrid fiber cross service gateways, and signaling gateways. Worldwide unit shipments and revenues for session border controllers and media servers are also provided by geographic region.
