Grandstream HT812 V2 2-Port ATA with Gigabit Router
Grandstream HT812 V2 2-Port ATA with Gigabit Router
The Grandstream HT812 V2 is a two-port ATA with two Gigabit network ports and a built-in NAT router. The second network port means a computer can share the same network drop as the analog phone or fax machine.
It handles two analog devices, the same as the HT802 V2. Pick the HT812 V2 when you want Gigabit or the extra port. Grandstream rates its NAT routing at up to 100Mbps.
Quick guide to the two port types: an FXS port provides dial tone, so you plug in an analog phone, fax machine, door phone or overhead paging amplifier. An FXO port takes dial tone, so you plug in an analog phone line from the phone company. Our Crosstalk PBX appliances are pure VoIP with no analog ports, so an ATA or gateway is how you bring analog devices or phone lines onto the system.

Good to know
- FXS only. It connects analog phones and devices, not phone lines from the phone company. For phone lines, use an FXO gateway like the Grandstream HT841.
- Fax over VoIP works best when your SIP provider supports T.38. Test your fax machine on the line before you rely on it.
