Grandstream • SKU HT813
A hybrid adapter with one FXS port for an analogue endpoint and one FXO port for a compatible analogue PSTN line.
The Grandstream HT813 combines one FXS port for a compatible analogue phone or fax device with one FXO port for a compatible analogue PSTN line. It supports two SIP profiles, dual 10/100 Mbps WAN/LAN ports with NAT, T.38 fax, three-way calling, automated provisioning and a hard relay that can connect the FXS endpoint to the FXO line during a power outage.
Quick answer: Choose HT813 only when the design needs both an FXS endpoint port and an FXO analogue-line port. It does not create a PSTN service and should not be assumed compatible with every NBN, carrier or emergency-calling arrangement.
Connect one analogue endpoint and one supported analogue trunk line in a single compact device.
Pass the FXS endpoint to the FXO line during power loss when wiring and carrier service are compatible.
Use two SIP profiles, T.38 fax and network routing in a validated design.
A quick fit check for Australian businesses comparing equipment for users, rooms, sites or wider projects.
