Four-port VoIP gateway with Gigabit router

The Grandstream HT814 combines four FXS ports with an integrated Gigabit NAT router in a single unit. It allows analogue telephones or fax machines to connect to a SIP-based VoIP service while sharing the broadband link. The device is aimed at small offices or home users who need multiple analogue lines without a separate router.

Suits multi-line analogue setups.

Installers moving several analogue extensions onto VoIP will find the four FXS ports and built-in routing convenient. Sites that already use only SIP endpoints or softphones gain no benefit from the FXS interfaces. Buyers who require Power over Ethernet for the gateway itself must look elsewhere, as the HT814 has no PoE support.

Four FXS ports determine analogue line count

The gateway provides exactly four RJ-11 FXS ports, so each analogue device occupies one port. This fixed number decides whether the unit matches the quantity of legacy phones or fax machines you intend to connect. No expansion option is mentioned in the specifications.

Questions about this item

How much power does the HT814 draw when all four FXS ports are active all day?

The gateway has no redundant power supply and uses a standard external adapter; typical consumption stays low because there is no fan or PoE circuitry.

Which analogue devices must I already own to connect to the four FXS ports?

You need up to four standard analogue telephones or fax machines with RJ-11 plugs; each port supplies ring voltage and dial tone for one device.

Will the Gigabit WAN and LAN ports negotiate 1000 Mbps with my older 10/100 switch?

Yes, the two RJ-45 ports support 10/100/1000Base-T and will auto-negotiate down to 100 Mbps or 10 Mbps for legacy equipment.
