Grandstream • SKU HT841
A hybrid analogue gateway with 4 FXO trunk ports, one FXS endpoint port, dual Gigabit Ethernet, PoE-PD and a high-performance NAT router.
The Grandstream HT841 connects 4 compatible analogue PSTN/FXO lines to a SIP platform and also provides one FXS port for an analogue endpoint. It supports three SIP profiles, dual Gigabit Ethernet, 802.3af PoE-PD on one network port, high-performance NAT, three-way conferencing per port, T.38 fax, TR-069 provisioning and secondary SIP-server failover. A hard relay can connect the FXS port to an FXO line during a power outage when the carrier service and wiring are compatible.
Quick answer: Choose HT841 when the project requires exactly 4 FXO analogue trunk ports plus one FXS endpoint port. The two interface types are not interchangeable, and the gateway does not create a carrier or PSTN service.
Bring 4 compatible analogue trunk lines and one analogue endpoint into a supported SIP design.
Use dual Gigabit networking and 802.3af PoE-PD on the supported port in a planned network.
Hard-relay the FXS endpoint to an FXO line during power loss when the full service design supports it.
A quick fit check for Australian businesses comparing equipment for users, rooms, sites or wider projects.
