D-Link DVG-6004S 4-Port VoIP Trunk Gateway

The D-Link DVG-6004S VoIP trunk gateway connects an IP network to POTS (plain old telephone service) analog lines to send IP voice and data to the conventional phone sets and fax machines. Designed as a cost-effective VoIP solution for a small to medium-sized business and the branch office, these devices provide 4 FXO (Foreign eXchange Office) ports for 4 phone line connections. IP network connection can be through any of the 2 LAN ports or the WAN port (all 10/100/1000Base-T Ethernet interfaces).

In a remote IP phone to local analog phone line application, a branch office can take in IP voice calls from a head office, then route them to local destinations equipped with only analog phones. The long distance calls are sent through the Internet without any phone charge, and the remote office pays only for the local analog phone time. The gateways connect analog callers to the IP network without involving operators or incurring toll charges from telephone companies.

The DVG-6004S VoIP gateway can be deployed to interface VoIP infrastructure with a Public Switched Telephone Network (PSTN)

They allow analog phone callers to place calls through the long-distance Internet trunk line. The gateways accept dial tone and ring current from the connected equipment, and facilitate the use of conventional phone sets and fax machines on a VoIP network.

The DVG-6004S gateway delivers clear sound, voice and reliable fax calling through implementation of internationally recognized standards for voice and data networking. It incorporates Quality of Service (QoS) functions to ensure that voice received through the Internet is the same as or even surpasses that received on the ordinary phone.

The DVG-6004S gateway supports extensive call features, allowing the service providers to offer these functions to their subscribers. Provided that the telephone sets at the end-users side support these functions, callers can take advantage of these convenient features. Configuration of individual phone connection is easy, using the multi-language Interactive Voice Response (IVR) or the web-based user's interface.
