Grandstream HT814 V2 4-Port Analog Telephone Adapter
The Grandstream HT814 V2 connects four analog devices to your VoIP phone system from one box. It's a good fit for a small office keeping a few analog phones, a fax machine and a door phone after a move to VoIP.
It has two Gigabit network ports and a built-in NAT router, so a computer can share the network drop.
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.
- Need more than four ports? The HT818 V2 has eight.
