1. Introduction
1-1 Product Overview
The DVG-N5412SP 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 VoIP Router can be configured to
establish a private VoIP network over the Internet without a third-party SIP Proxy Server.
The DVG-N5412SP 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 Router allows you to use voice and fax services over IP in order to reduce the cost of all long
distance calls.
The DVG-N5412SP is also an 802.11b/g/n 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 DVG-N5412SP 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, G.723.1 or iLBC voice compression format to save network
bandwidth while providing real-time, toll quality voice transmission and reception.
