D-Link DVG-6004S

details: 4-Port VoIP Trunk Gateway
hardware type: VoIP Gateway
date added: 2010-07-29
updated: 2015-11-08
The D-Link DVG-6004S VoIP trunk gateways connect 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 4 LAN ports or the WAN port (all 10/100BASE-TX Ethernet interfaces).

The DVG-6004S gateways deliver clear sound, voice and reliable fax calling through implementation of internationally recognized standards for voice and data networking. They incorporate 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.
