4-Port SIP Internet Telephony Gateway
VGW-400 Series
Chapter 1 Introduction
Cost-effective, High-performance PoE VoIP Phone
To build high-performance VoIP communications at a low cost, PLANET now introduces the latest
member of its gateway family, the VGW-400 enterprise-class 4-port SIP VoIP Gateway series. The
VGW-400 series provides added flexibility during migration to Unified Communications by supporting
the traditional analog devices. These devices include analog phones, fax machines, modems,
voicemail systems, and speakerphones. It helps the company to save money on long-distance calls; for
example, the remote workers can dial in through a Unified VoIP Communication System just like an
extension call but no long-distance call charge would occur. The VGW-400 series also allows call to be
transferred to anyone at any location within the voice system, which enables the enterprise to
communicate more effectively and is helpful to streamline business processes.
Standard Compliance
The VGW-400 series supports Session Initiation Protocol 2.0 (RFC 3261) for easy integration with
general voice over IP system. The VGW-400 series is able to broadly interoperate with equipment
provided by VoIP infrastructure providers, thus enabling them to provide their customers with better
multi-media exchange services.
