Grandstream HT814 v2 is a four-port VoIP gateway for connecting analogue telephone devices to an IP telephony network. It combines four FXS phone ports with a built-in Gigabit NAT router, bringing telephony and network connections together in one device.
The gateway supports two SIP profiles, with four RJ11 FXS interfaces for phones and two RJ45 network ports operating at 10/100/1000 Mbps. Three-way voice conferencing is supported on each port, making the unit suitable for setups that need multiple analogue phone connections and conference calling.
For fax over IP, HT814 v2 supports T.38 and can switch automatically to G.711 fax pass-through. Provisioning options include TR-069 and XML configuration files, and the gateway can be used with Grandstream UCM IP PBXs for zero-configuration provisioning.
