Description
Businesses that still rely on traditional phone lines but want the power and savings of VoIP love the Grandstream HT881. This 8-port analog FXO gateway makes it simple to connect up to eight PSTN lines directly to your hosted or on-premise IP PBX. Whether you run a small office, branch location, or hybrid phone system, the HT881 gives you seamless calling, faxing, and reliable backup—without ripping out your existing analog setup.
Our Expert Take
The HT881 stands out when you need more analog lines than the 4-port HT841 can handle. Its lifeline feature is a real lifesaver: during a power outage the FXS port automatically routes through an FXO line so your analog phone stays live for emergency calls. Add the built-in high-performance NAT router, dual Gigabit Ethernet ports with PoE, and three independent SIP profiles, and you get a flexible, future-proof gateway that IT teams actually enjoy deploying.
