About Grandstream HT812V2 2 FXS 2 GIGE NAT Router

The Grandstream HT812 V2 is a compact, reliable 2-port analogue telephone adapter (ATA) that bridges the gap between traditional analogue phones and a modern VoIP phone system. With two FXS ports, dual Gigabit network ports, and a built-in NAT router, it's a great pick for homes and small offices that want to keep their existing analogue handsets or fax machines running on a SIP-based system — without the hassle of replacing every device.

Key Features

2 FXS Ports — Connect up to two analogue phones, fax machines, or other analogue endpoints, each running its own independent SIP profile.
Dual Gigabit Ethernet Ports with Built-In NAT Router — Two 10/100/1000Mbps RJ45 ports with an integrated NAT router handle routing speeds up to 100Mbps, keeping your network running smoothly alongside your voice traffic.
HD Voice Quality — Wideband audio codec support delivers clear, natural call quality well above what standard analogue lines can offer.
T.38 Fax Over IP — Supports T.38 compliant fax relay up to 14.4kbps, with automatic fallback to G.711 for fax pass-through — so your fax setup keeps working reliably.
TLS & SRTP Encryption — Protects calls and account credentials with strong encryption and a unique security certificate per unit.
Automated Provisioning — Supports TR-069 and XML config file provisioning, making it straightforward to deploy and manage at scale. Works with Grandstream's UCM IP PBX series for zero-configuration setup.
