This compact analog FXO gateway lets you keep your existing PSTN service while connecting everything to your IP phone system.

Whether you’re moving to a hosted PBX or keeping a mix of old and new phones, the HT841 makes the transition smooth and worry-free.
The Telecom Spot Expert Review
The Grandstream HT841 shines when reliability matters most. The standout lifeline feature automatically routes the FXS port to an FXO line if power fails—perfect for offices that can’t risk downtime. We also love the three SIP profiles that give you flexibility for multi-location or multi-tenant setups, and the T.38 fax support keeps those old fax machines working without extra hardware. Pair it with Grandstream’s GDMS cloud management for remote monitoring and fast provisioning. Quick setup tip: configure the FXS lifeline early and test failover once—it takes just minutes and gives real peace of mind. Overall, this is a cost-effective, future-proof gateway that delivers professional-grade performance without complexity.
