Ht812 V2

Grandstream HT812 V2 is a two-port analog telephone adapter designed to connect traditional telephones to SIP-based communication services. Its built-in Gigabit NAT router combines voice connections and network access in one device.

Two RJ11 FXS ports support two SIP profiles, while two 10/100/1000 Mbps RJ45 ports provide wired network connections. The adapter also supports three-way voice conferencing on each port and T.38 Fax over IP, making it suitable for setups that use analog phones and fax equipment alongside IP telephony.

TR-069 and XML configuration files are available for automated provisioning. The built-in router handles routing speeds up to 100 MBps.
