Introduction
The D-Link DVG-2101SP VoIP Telephone Adapter links conventional telephony devices such as analog phones
or fax machines to IP networks. The DVG-2101SP includes one Ethernet port and one RJ-11 telephone jack
that provides voice communication over the IP network. It is also equipped with one PSTN (RJ-11) jack to
allow the device to connect to the PSTN line. The Ethernet port is for a DSL/Cable Modem or other WAN (Wide
Area Network) devices such as a Router or Gateway. It can be configured and monitored using a web browser.
This VoIP Telephone Adapter can reduce or eliminate long distance or inter-office phone charges by routing
calls over the Internet or any IP network. Corporations can also enjoy the benefits of network consolidation
and reduction of leased lines by relying on the Internet service providers to deliver toll-quality voice
communications over the IP networks.
With this device, you can make and receive calls from the Internet or PSTN (make only).
