Internet IP telephony, also called Voice over IP (VoIP), is defined as the transport of telephone calls over the Internet as standard Internet data packets. Internet telephone calls can originate from traditional phone handsets via phone-line-to-Internet (Analog Trunk) gateways, by PCs using software, or embedded devices (IP Phones). Most of the interest in Internet telephony is motivated by cost savings and easy of developing and integrating new services. Internet telephony integrates a variety of services provided by the current Internet and the Public Switched Telephone Network (PSTN) infrastructure.

An Analog Trunk Gateway is the bridge between local PSTN (Public Switched Telephone Network) phone lines and any Ethernet IP network. The result is your phone and FAX services can converge with to your data network. The DVG-3004S features four RJ-11 analog FXO ports for connecting to the local PSTN phone lines and one 10/100 Base-TX connector for local Ethernet network.
