1. Introduction
1-1 Product Overview
The DVG-G5402SP Wireless VoIP Gateway is designed to carry both voice and facsimile over the IP network and
wirelessly share Internet access. 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 gateway can be
configured to establish a private VoIP network over the Internet without a third-party SIP Proxy Server.
The gateway 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 gateway allows you to use voice and fax services over IP in order to reduce the cost of all long distance
calls.
The DVG-G5402SP is also an 802.11b/g wireless access point. Allow wireless clients to connect to it and share
your broadband Internet connection. A built-in 4-port switch makes it possible to connect up to 4 Ethernet-enabled
computers or devices to also share your Internet connection.
The wireless voip gateway can be configured a fixed IP address or it can have one dynamically assigned by
DHCP over 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.
