Overview
- The Grandstream HT841 is a professional-grade FXO gateway that bridges traditional analog phone lines with modern VoIP infrastructure. It enables businesses to integrate multiple PSTN connections into hosted or on-premise IP PBX systems without replacing existing analog equipment, reducing capital expenditure and simplifying network convergence.
With support for 4 FXO and 1 FXS port, the HT841 accommodates diverse calling scenarios across multiple locations. Lifeline protection ensures critical phone lines remain functional during power outages by automatically relaying the FXS port to an available FXO connection, maintaining business continuity when it matters most.
The gateway delivers enterprise-level reliability through dual SIP server failover, ensuring calls route to a backup server if the primary connection fails. Advanced features including T.38 fax-over-IP, 3-way conferencing, and automated TR069 provisioning make it ideal for organisations seeking to simplify deployment and reduce ongoing management overhead.
Strong AES encryption and per-unit security certificates protect voice traffic, meeting security requirements for regulated industries and privacy-conscious enterprises.

FAQs
What is the difference between FXO and FXS ports on the HT841?
FXO ports connect to PSTN lines (incoming external connections), while the FXS port connects to analog phones or fax machines. The HT841's 4 FXO ports support multiple PSTN lines, and the 1 FXS port enables an analog device to use the gateway.
How does lifeline support work during a power outage?
Lifeline support automatically relays the FXS port to an available FXO port, ensuring that an analog phone connected to the FXS port can still make and receive calls using a PSTN line if the gateway loses power, maintaining critical communication capability.
Can the HT841 support faxing?
Yes. The HT841 supports T.38 fax-over-IP, enabling reliable facsimile transmission over your VoIP network rather than requiring a dedicated fax line.
What happens if my primary SIP server goes down?
The HT841 automatically detects if the primary SIP server is unreachable and switches to a secondary failover server, ensuring uninterrupted calling without manual intervention.
Is the HT841 suitable for multi-site deployments?
Yes. The HT841 is designed to connect multiple office locations and devices to a centralised hosted or on-premise IP PBX system, making it ideal for distributed enterprise networks.
How is provisioning managed across multiple gateways?
The HT841 supports automated and secure provisioning using TR069, allowing IT administrators to configure and manage multiple gateways remotely without manual setup at each location.
Does the HT841 encrypt voice traffic?
Yes. The gateway uses strong AES encryption and includes a per-unit security certificate to protect voice communications against unauthorised interception.
