1. Introduction
1-1 Product Overview
The DVG-5004S are designed to carry both voice and facsimile over the IP network. It uses the industry standard
SIP call control protocol so as to be compatible with free registration services or VoIP service providers’ systems.
As a standard user agent, it is compatible with all common Soft Switches and SIP proxy servers. While running
optional server software, the VoIP Gateway can be configured to establish a private VoIP network over the
Internet without a third-party SIP Proxy Server.
The DVG-5004S can be seamlessly integrated into an existing network by connecting to a phone set and fax
machine. With only a broadband connection such as an ADSL bridge/router, a Cable Modem or a leased-line
router, the VoIP Gateway allows you to use voice and fax services over IP in order to reduce the cost of all long
distance calls.
The DVG-5004S can be configured a fixed IP address or it can have one dynamically assigned by DHCP or
PPPoE. It adopts either the G.711, G.726, G.729A or G.723.1 voice compression format to save network
bandwidth while providing real-time, toll quality voice transmission and reception.
