HARDWARE FEATURES
VoIP | LSG VoIP Gateway
Product Overview
LSG is a 2 ports or 4 ports stand-alone VoIP gateway that carries both voice and facsimile over an IP network.
It supports SIP (RFC 3261) call control protocols. As a standard user agent, it is compatible to all
well-known Soft Switches and SIP proxy servers. With only a broadband connection such as an ADSL
bridge/router, Cable Modem or leased line router, it allows you to gain access to voice and fax
services over IP in order to reduce the cost of international and long distance calls.
In addition, the in-built 4 ports switch supports comprehensive Internet gateway functions to
accommodate other PCs or IP devices to share the same broadband stream. QoS function allows voice
and data traffic to flow through where voice traffic is transmitted in highest priority.
