Analog VoIP Gateway Grandstream Networks HT801‑V2, 10/100 Mbps Ethernet, single FXS port, black

The Grandstream Networks HT801-V2 is an analog VoIP gateway designed to connect a single analog telephone or fax machine to an IP network. This compact black ATA supports a 10/100 Mbps Ethernet connection and implements common internet and telephony protocols such as TCP/IP, UDP, RTP/RTCP, HTTP/HTTPS, DNS, DHCP, NTP, TFTP and SSH. With one FXS port and support for a single SIP profile, the HT801-V2 is intended for home and small office SIP deployments where a straightforward, standards-based analog-to-IP conversion is required.

Advantages

The HT801-V2 offers a simple and compact solution for integrating legacy analog phones and fax devices into modern VoIP environments. Built-in security features include TLS and SRTP encryption for signaling and media protection, and the device supports automated provisioning options such as TR-069 and XML configuration files for centralized setup. LED status indicators for power, network and phone simplify monitoring, while support for T.38 fax and multiple caller ID formats ensures compatibility with common telephony use cases.

How to use

Physically connect the HT801-V2 to your LAN using a standard Ethernet cable and plug the analog telephone or fax into the FXS port. Configure network settings via DHCP or manual IP assignment, then provision the device with your SIP account details either manually through the web interface or automatically using TR-069/XML provisioning or GDMS. Ensure TLS/SRTP settings match your SIP provider or PBX configuration to secure signaling and media. For fax use, enable T.38 on both the gateway and the receiving endpoint for reliable Fax-over-IP operation.

Usage recommendations

For reliable voice quality, connect the HT801-V2 to a network with QoS configured to prioritize SIP/RTP traffic and use a stable internet connection. When managing multiple Grandstream devices, consider using the Grandstream Device Management System (GDMS) for centralized, zero-touch provisioning, firmware updates and monitoring. Verify compatibility of caller ID formats and enable T.38 on both ends when sending or receiving faxes to reduce transmission errors.
