Grandstream HT814 V2 is a four-port VoIP gateway for connecting analog telephones and fax machines to an IP telephony service. It combines four FXS telephone connections with an integrated Gigabit NAT router, making it suitable for home and office voice setups.
Its four RJ11 FXS ports connect analog devices, while two RJ45 network ports support Gigabit Ethernet. NET1 is configured as WAN and NET2 as LAN by default. The gateway supports two SIP profiles and three-way voice conferencing on each port.
Wideband HD voice codecs support voice calls, and T.38 enables fax over IP. For deployments that need centralized setup, the device supports automated provisioning through TR-069, with AES encryption. It provides a practical bridge between analog phone or fax equipment and VoIP networking.
