VoIP gateway with Gigabit NAT

Grandstream HT814 V2 is a VoIP gateway that connects analog telephone equipment to SIP-based voice services while providing an integrated Gigabit NAT router.

It offers four RJ11 FXS telephone ports and supports two SIP profiles, allowing several analog phone lines to use VoIP through one gateway. Its two RJ45 Gigabit network ports support link rates up to 10/100/1000 Mbps.

Wideband HD codecs support clearer voice transmission, and three-way conferencing is available on each port. T.38 fax over IP is also supported, making the unit useful where analog phones and fax equipment need to work with an IP telephony setup.
