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 Series enterprise-class 4-port SIP VoIP
Gateway. 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.
