Grandstream HT814-V2 4-Port VoIP Gateway ATA

The Grandstream HT814 V2 is the four-port analogue gateway — the middle of the HandyTone range, and usually the one that fits. Four analogue phones, fax machines, door phones or alarm diallers keep working on a VoIP system, in a small fanless box that does not need a rack.

Two SIP profiles let the four ports be split between providers or systems, and the two Gigabit ports with a built-in NAT router mean it can sit inline at a small site rather than behind an existing router.

Key features

• 4 FXS ports — four independent analogue devices
• 2 SIP profiles — the ports can use different providers or systems
• 2 Gigabit Ethernet ports with a built-in NAT router
• T.38 fax relay to 14.4 kbps, with automatic fallback to G.711
• Wide codec support — G.711, G.723.1, G.726, G.729A/B, iLBC and Opus
• HD voice on the analogue ports
• TLS and SRTP — signalling and media encryption
• Automated provisioning — deploy without touching each unit
• Fanless — silent enough for an office

Works with

• HT812 V2 — two FXS ports
• HT818 — eight FXS ports
• HT813 — one FXS and one FXO, for a PSTN fallback line
• PSU for HT814 — spare or replacement power supply
• GXW4216 V2 — 16 ports, when the count grows
• Grandstream UCM IP PBX range — register the ports to an on-site PBX

Frequently asked questions

Will my existing analogue phones just work?

Yes. An FXS port supplies line voltage, dial tone and ring current exactly as an analogue exchange line does, so the handsets behave normally.

Do fax machines actually work over this?

It supports T.38 fax relay, which carries the fax as data instead of pushing fax tones through a voice codec, and falls back to G.711 if T.38 is unavailable. Your provider or PBX also needs to support T.38.

What is the difference between the HT814 and the HT814 V2?

V2 is the current hardware revision of the same product — four FXS ports, two SIP profiles, Gigabit NAT router. If you are buying now, buy the V2.

2, 4 or 8 ports?

One port per analogue device. Count the handsets, faxes, lift phones and alarm diallers first — it is normal to find more than expected. Four covers most small offices; beyond eight, move up to a GXW gateway.

Can different ports use different providers?

Yes — that is what the two SIP profiles are for.

Does it need to be my router?

No. The NAT router is there if you want it inline at a small site, but it works perfectly well plugged into an existing network as an ordinary device.
