Grandstream HT801 v2 1 FXS VoIP Adapter - Compact Reliable Adapter

Our review of the Grandstream HT801 v2 finds it is a compact, no-nonsense analog telephone adapter aimed at small offices and home users who need a simple, secure way to connect a single analog phone to a SIP VoIP service. The single FXS port and single 10/100Mbps Ethernet port make the HT801 v2 easy to deploy where desk space and network ports are limited, and built-in security like TLS and SRTP gives confidence for everyday voice use. This is not a multi-line PBX replacement, but it is ideal when one reliable analog extension on IP is required.

Key Features

• Single FXS port: Provides a straightforward way to connect a single analog telephone to a SIP service without extra hardware.
• 10/100Mbps Ethernet: The single fast Ethernet port allows simple network integration on typical office or home switches.
• Security encryption: TLS and SRTP protect call signaling and media to reduce the risk of eavesdropping and account compromise.
• Automated provisioning: TR-069 and XML config file support make large or remote deployments easier to manage and update.
• Advanced telephony features: Call transfer, call forward, call waiting and message waiting indication let the ATA behave like a conventional phone line.
• Fax over IP: T.38 support helps maintain reliability when sending faxes across an IP connection.

Who It's For

The HT801 v2 is best for small businesses, home offices, or remote workers who need to convert one analog handset or fax machine to SIP with minimal setup. It suits IT teams that want a compact single-port ATA that supports TR-069 provisioning and works with Grandstream UCM systems for zero-touch deployment.

It is not aimed at users who require multiple concurrent analog lines, built-in PBX features, or gigabit throughput; larger offices should look at multi-port ATAs or full IP PBX solutions instead.

Pros & Cons

Pros

• Compact single-port design is easy to place on a desk or shelf without extra cabling complexity.
• Strong security with TLS and SRTP helps protect calls and accounts on public or private networks.
• Provisioning options including TR-069 and XML make fleet management and remote updates straightforward.
• T.38 fax support and wide caller ID compatibility cover common analog use cases.

Cons

• Only one FXS and one 10/100Mbps port limits expansion and throughput for larger sites.
• No built-in multi-line PBX features - intended as a single-line ATA rather than a multi-port replacement.

Specifications

The Grandstream HT801 v2 is a practical, value-oriented ATA for anyone who needs a single reliable analog extension on a SIP network.
