Review: Easy to use and highly configurable VoIP gateway - This device is so cool and useful - I actually bought it so that I could add some analog telephones to my house for my daughters, so that I can avoid giving them smart phones, with a goal toward hooking it up to a VoIP PBX at some future point so that the phones can actually dial out. It works great - my daughters are able to call each others' rooms, which is fun, and the initial setup is pretty easy. It's a very flexible, configurable device. The only thing it's lacking is the ability to disable the lines on a schedule - other than that, it works great! Review: Nice gateway with lots of FXS ports - I bought this product for the 8 port FXS gateway, not the router, so I can't review that. I'm using the HT818 to replace a Cisco SPA112 that is EOL now. The price is GREAT for 8 ports. Setup is simple, fast and easy especially with the t38Fax guides. Right now I have only 2 lines setup on the HT818 (via 1 trunk): 1 line is a voice line through t38Fax with a local area code connected to a cordless phone system. The other line is connected to a standard all-in-one printer with fax machine built in and it works great! This second line also has a local area code. I have two more lines with TFNs connected to Bria Solo (soft phone) and T38 Fax & Voice for a software approach to sending and receiving calls and faxes. I went with a software fax so I don't need a seperate physical fax machine to carry around. It's super handy. The HT818 I received did not have the latest firmware on it, which you can download from GrandStream's website and upload into the gateway easily from the bin file. Otherwise, everything basically worked out of the box and I was up and running within minutes. ## Features - Supports 2 SIP profiles and 8 FXS ports - High performance NAT router - Strong AES encryption with security certificate per unit - Automated & secure provisioning options using TR069 - 3-way voice conferencing per port ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07B6TL7N6 | | Antenna Location | voip gateway | | Best Sellers Rank | #107,565 in Electronics ( See Top 100 in Electronics ) #710 in Computer Routers | | Brand | Grandstream | | Built-In Media | Gateway | | Color | Black | | Compatible Devices | Analog Telephones | | Connectivity Protocol | SIP, T.38, IP | | Connectivity Technology | 3-way voice conferencing, fax-over-IP | | Control Method | App | | Controller Type | App Control | | Customer Reviews | 4.6 out of 5 stars 92 Reviews | | Data Transfer Rate | 1000 Megabits Per Second | | Frequency Band Class | Tri-Band | | Has Internet Connectivity | Yes | | Has Security Updates | Yes | | Is Electric | Yes | | Is Modem Compatible | No | | Item Dimensions L x W x H | 5.14"L x 3.56"W x 1.14"H | | Item Weight | 500 Grams | | LAN Port Bandwidth | 1000 Mbps | | Manufacturer | GRANDSTREAM | | Maximum Upstream Data Transfer Rate | 1000 Megabits Per Second | | Mfr Part Number | HT818 | | Model Name | HT818 | | Model Number | HT818 | | Number of Ports | 8 | | Operating System | Android | | Other Special Features of the Product | Advanced Networking Technology, 3-way Voice Conferencing, Fax-over-IP Protocol, High Performance NAT Router, Strong AES Encryption | | Router Network Type | Wired | | Security Protocol | AES | | Special Feature | Advanced Networking Technology, 3-way Voice Conferencing, Fax-over-IP Protocol, High Performance NAT Router, Strong AES Encryption Special Feature Advanced Networking Technology, 3-way Voice Conferencing, Fax-over-IP Protocol, High Performance NAT Router, Strong AES Encryption See more | | UPC | 694727370241 753459298497 | | Voltage | 110 Volts, 220 Volts | | Warranty Description | 1 year | | Wireless Communication Standard | 802.11g | | Wireless Compability | 802.11g | ## Product Details - **Brand:** Grandstream - **Color:** Black - **Compatible Devices:** Analog Telephones - **Connectivity Technology:** 3-way voice conferencing, fax-over-IP - **Frequency Band Class:** Tri-Band - **Included Components:** Gateway - **Model Name:** HT818 - **Recommended Uses For Product:** voip gateway - **Wireless Communication Standard:** 802.11g ## Images ![Grandstream Powerful 8-Port FXS Gateway with Gigabit NAT Router (HT818) - Image 1](https://m.media-amazon.com/images/I/61+x+ztuLRL.jpg) ## Questions & Answers **Q: Does this have a built in firewall?** A: No **Q: Can the ethernet ports be used in bridge mode instead of nat mode? if so can they bridge traffic at a full 1gbps?** A: I don't know why you would want to set it up in bridge mode, except for maybe a 1ms reduction in latency for SIP calls, while slowing down your main networks traffic, via a new choke point. Also the reason you can't use this in bridge mode is it would require it's own IP Address, and your router would need one too, most ISPs won't let you use 2 IPs from the same connection. Now a bridge mode where it uses the same IP from your ISP is possible, but that would still be using some NAT for it's self and your router. If you attach this straight to your router and main network, bypassing this ATAs NAT firewall, you wouldn't be increasing latency by any noticeable amount, nor adding another choke point, and you won't be adding to a complicated mess of cables. If you just run an Ethernet cable from your routers LAN port to the Internet port on this, and it should work as long as you have its IP Configuration setting to be DHCP or Automatic, which should be the default. You may need to forward some ports in your router though, but the service provider your using should tell you if you need to and how to set it up and what to enter in. By the way I do not own one of these ATAs but have done a very high level of research on these types of ATAs, and have been working on Small Business/Large Scale Home IT networking for the past 4-6 years. **Q: Does this device work with fax machines using itu-t super g3?** A: Yes, the Grandstream HT818 supports fax machines using ITU-T Super G3 protocol. The device is designed to support T.38 fax relay, which is an industry-standard protocol for sending faxes over IP networks. **Q: Can this unit power the rj11 fxs ports to power analog phones?** A: The data sheet lists a Ring Equivalence Number (REN) of 2 so it should be able to ring up to 2 analog phones simultaneously. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use and highly configurable VoIP gateway *by V***K on June 4, 2025* This device is so cool and useful - I actually bought it so that I could add some analog telephones to my house for my daughters, so that I can avoid giving them smart phones, with a goal toward hooking it up to a VoIP PBX at some future point so that the phones can actually dial out.

Otherwise, everything basically worked out of the box and I was up and running within minutes. ### ⭐⭐⭐⭐⭐ I've always had good luck with Grandstream devices. *by T***I on March 1, 2025* Firmware looks a bit dated but works fine. I was able to connect it to a Asterisk server with no fuss, and had a line up quickly. Pulse dialing works but is disabled by default. I was able to send a test fax with no issues. It supports 8 lines across two separate SIP servers. All the lines can be on one SIP server or split between two. Out of the box it just did what I expected it to do, I've always had good luck with Grandstream devices. I don't intend to use it as a router, other than possible QoS routing complexity I recommend putting it behind another firewall device. But if you're buying a ATA you probably already know all about congestion and QoS. ## Frequently Bought Together - Grandstream VoIP Gateway 8-Port FXS with Gigabit NAT Router (HT818) - Grandstream GS-HT814 4 Port Ata with 4 Fxs Ports and Gigabit NAT Router Voip Phone and Device, Black - Grandstream 2-FXS Port Analog Telephone Adapter (HT802) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/67364879-grandstream-powerful-8-port-fxs-gateway-with-gigabit-nat-router](https://www.desertcart.us/products/67364879-grandstream-powerful-8-port-fxs-gateway-with-gigabit-nat-router) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-13*
