VoIP D-Link DVG-5004S

D-Link DVG-5004S 4-Port VoIP Gateway

The D-Link DVG-5004S is a VoIP gateway with four RJ-11 FXS ports that connects analog phones and fax machines to SIP-based internet telephony. Existing equipment can stay in use while the office moves to a VoIP service.

It includes a built-in router with NAT and a DHCP server, one WAN port and four 10/100 LAN ports, so a single internet connection can be shared between the office computers and phones.
