Description
Connect Up to 8 Analogue Phones to Any VoIP Network
The HT818 is a powerful 8-port VoIP gateway with 8 FXS ports and an integrated Gigabit NAT router, built for users looking for a strong analogue-to-VoIP converter. Where FXO gateways bring PSTN lines into a VoIP system, the HT818 does the reverse — it connects existing analogue desk phones and fax machines to a SIP-based IP PBX or hosted VoIP platform, allowing businesses to preserve their investment in analogue handsets while moving to a modern telephony infrastructure.
Key Highlights
- 8× RJ11 FXS ports — connect up to 8 analogue phones or fax machines
- 2× 10/100/1000 Mbps Gigabit Ethernet ports with integrated Gigabit NAT router
- 2 SIP profiles supported across all 8 FXS ports
- Grandstream’s market-leading SIP ATA/gateway technology with millions of units deployed worldwide
HD Voice Quality & Broad Codec Support
The HT818 carries exceptional voice quality in various application environments, with wideband HD codec support delivering noticeably clearer audio than standard narrowband telephony. A broad codec selection ensures compatibility across different VoIP platforms and network conditions.
- G.711 Annex I/II, G.723.1, G.729A/B, G.726, iLBC, and Opus codec support
- Wideband HD audio for superior voice clarity
- T.38 compliant Fax-over-IP for reliable fax transmission across VoIP links
- Layer 2 (802.1p/Q) and Layer 3 (ToS, DiffServ, MPLS) QoS support for prioritised voice traffic
Rich Telephony Features
Advanced telephony features include call transfer, call forward, call waiting, do not disturb, message waiting indication, multi-language prompts, and flexible dial plan support — covering the full feature set that business users expect from their desk phones, delivered seamlessly through the analogue handsets they already have.
- Call transfer, call forward, call waiting, DND, and message waiting indication
- 3-way voice conferencing per port for in-office collaboration
- Flexible dial plans for advanced call routing

Enterprise-Grade Security & Easy Management
Strong encryption with a unique security certificate per unit and automated provisioning for volume deployment and device management make the HT818 equally suitable for single-site and large multi-site deployments. Provisioning options include HTTP, HTTPS, SSH, TFTP, TR-069, and automated provisioning with AES encryption and syslog — integrating naturally into existing device management workflows.
