The Dlink DVG6004S Dubai VoIP trunk gateways link an IP network to POTS (plain old telephone service) analog lines to transmit IP voice and data to traditional phone sets and fax machines. Intended as an affordable VoIP option for small to medium-sized businesses and branch offices, these devices offer 4 or 8 FXO (Foreign eXchange Office) ports for 4 or 8 phone line connections. The IP network connection can be established through any of the 4 LAN ports or the WAN port (all 10/100BASE-TX Ethernet interfaces).
