**Product Overview**
The **Grandstream** **HT841** Analog FXO Gateway is a hybrid VoIP gateway designed to connect traditional analogue PSTN (POTS) telephone lines to SIP-based IP PBX systems. It is part of **Grandstream**’s HT8xx series and is typically used to bridge legacy telephone infrastructure with modern VoIP networks in business environments.
Featuring 4 FXO ports and 1 FXS port, the **HT841** allows organisations to integrate multiple PSTN lines into a VoIP system while still supporting a single analogue device (such as a phone or fax machine) locally. It also includes an integrated NAT router and supports advanced telephony features for flexible deployment in hybrid communication environments.
**Ideal For**
- Small to medium-sized businesses
- Branch offices and remote sites
- Hybrid PSTN + VoIP deployments
- Call routing and SIP trunk integration
- Legacy PBX migration projects
- Failover PSTN line support
**Benefits**
The HT841 enables organisations to connect existing analogue phone lines directly into a VoIP system, helping to reduce dependency on traditional PBX infrastructure. It provides a cost-effective migration path to SIP while maintaining PSTN connectivity for redundancy or local calling.
- Its built-in routing and provisioning capabilities make it suitable for distributed or multi-site deployments where reliability and failover are important.
