Two FXS ports for analog phones

The Grandstream GS-HT802 connects two standard telephones or fax machines to a VoIP network through its pair of FXS ports. It is aimed at home users and small offices that want to keep existing handsets while moving to SIP telephony. The adapter also suits service providers deploying large-scale IP voice services.

Single 10/100 Mbps Ethernet uplink

A single auto-sensing 10/100 Mbps RJ45 port carries all voice traffic for both lines. This shared uplink is the specification that determines whether the device fits a given network layout; environments requiring gigabit throughput or separate wired paths for each line will need a different solution.

Passive cooling in a compact chassis

The unit runs silently without fans and draws minimal power from its external supply. In normal operation the small enclosure stays cool to the touch, making it suitable for desk or wall mounting in quiet rooms. No thermal throttling or audible noise occurs under typical call loads.

Questions about this item

What does the 2 FXS ports figure mean for my analog phones?

You can connect two separate analog telephones or fax machines and register each to its own SIP account, so both lines operate independently over the same network connection.

What does the 10/100 Mbps ethernet port cap in practice?

The single RJ45 port negotiates at either 10 or 100 Mbps, so all voice traffic, provisioning data and fax-over-IP share that bandwidth ceiling.

How much space does the adapter need on a desk or wall?

The unit is ultra-compact and designed for desktop placement or wall mounting without requiring a rack shelf or special brackets.
