Grandstream Networks HT812 v2

The Grandstream HT812 v2 is a high-performance analogue telephone adapter (ATA) built to link conventional analogue telephones, fax machines or PBX systems to IP-based VoIP networks. It comes with two FXS ports, allowing it to handle two separate analogue lines, which makes it a great fit for small offices or home offices in need of dependable voice communication. For network connectivity, the unit provides dual 10/100 Mbps Ethernet ports, and it supports advanced security protocols such as TLS and SRTP to keep voice traffic encrypted.

With automated provisioning through TR-069 or XML configuration files, the HT812 v2 makes deployment and management easier in multi-unit setups. It also offers 3-way audio conferencing, T.38 fax support, and a variety of codecs such as G.711, G.722 and G.729. Its compact design and Power over Ethernet (PoE) capability (with an optional adapter) make it a flexible option for bringing legacy analogue devices into modern VoIP systems.
