VoIP Gateway with built-in 4 FXO, 1 10/100Mbps WAN & 4-port 10/100Mbps Switch

Part Number: DVG-6004S/E

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).

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
