The environment surrounding enterprise communication systems is changing drastically. Enterprises are thus demanding flexible communication systems that not only minimize running costs but also keep pace with rapid environmental changes. Moreover, the strategic direction in enterprises places high value on communication systems that can support the construction of various kinds of customer channels and improve customer services by utilizing the Internet and Intranets effectively. Using the voice over Internet protocol (VoIP), which integrates voice and data networks, is a key approach to such systems for both wide area networks (WANs) and local area networks (LANs). The LAN approach combines communication systems with business applications, upgrading the systems to the level of electronic commerce, including providing a call center on the Web. Hitachi provides both LAN and WAN solutions that use VoIP to reduce communication costs.
