1. Introduction

Product Overview

The stand-alone VoIP Gateway carries both voice and facsimile over the IP network. It supports

SIP industry standard call control protocol to be compatible with free registration services or VoIP

service providers’ systems. It works in two different modes: UA (User Agent) or Server. As a

standard user agent, it is compatible to all well-known Soft Switches and SIP proxy servers.

While running the optional server software, the gateway can be configured to establish a private

VoIP network over the Internet without a 3

party SIP Proxy Server.

The gateway can be seamlessly integrated to existing network by connecting to a phone set,

PBX, key telephone system, fax machine or PSTN line. With only a broadband connection such

as 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.

With the support of DDNS, it makes the gateway reachable by its domain name where the ISP

dynamically assigns the IP address. It helps users to host a web site or mail server in a PPPoE

or DHCP network. By enabling the CDR function & setting up a simple server, administrators are

allowed to log and view all call records such as call duration, time and date of calls and latency,

etc.

The gateway can be assigned with fixed IP address or by DHCP, PPPoE. It adopts the G.711,

G.726, G.729A or G.723.1 voice compression format to save the network bandwidth while

providing real-time and toll quality voice.
