Grandstream HandyTone 801 Single-Port Analog Telephone Adapter (HT801), Corded, Black.

Works well with VOIP service from voip.ms (which is very inexpensive). It does require care in setting up.

I have a small PC-based phone system for my house. It's cheaper than any kind of IP phone from any company, but I didn't want a Cisco desk phone wired in, so I bought this and connected it to my PBX and then plugged in my Panasonic 5 station cordless phone set. It was easy to set up, the instructions were clear and covered every case - and unlike many pieces of modern electronic, has never had to be reset in order to work.

I've started to collect analog phones but have never been able to actually try them out, so I decided to get an ATA and cheap VoIP service so I could give them a spin. The HT801 was recommended as a good ATA for analog telephony hobbyists/enthusiasts like me. There is no guidance on how to get started with the device in the box, but luckily I found a manual on their website (which interestingly says it should come with a quick start guide). There are a LOT of settings you can fiddle with on the web UI. One thing I did was I turned off SSH access which unexpectedly seems to also disable the web UI, so I'm glad my VoIP provider offers setup instructions specifically for the HT801 and I got it configured and working before discovering this... I'll have to reset it and reconfigure everything to get that web UI back. I also was able to turn on pulse dialing support, which is crucial for using my rotary phones. But yeah, after everything was set up, I was able to place and receive calls no problem with very good audio quality for phones at least 50 years old. The ringers on the phones also worked fine when receiving calls, which is something I was slightly worried about. Overall I'm pleased with this little device and excited to do more with it. It'd be 5 stars if not for the fact that now I'm going to have to reset it and start all over due to the unexpected "no ssh, no web UI" problem.

I confirmed that the seller TeleDirect is selling HT801 V2 with the US style plug. I have tested both V1 and V2 with voip(.ms) and they both work fine, incoming and outgoing calls. Both V1 and V2 can be powered from a USB type A hub. For example, I'm using one of the USB type-A ports on my WiFi router to power the GrandStream device. Here are the differences I have noticed, but there are probably more. Differences: The major difference is the webportal is majorly updated. It looks more modern, it's faster, more organized, and provides a find setting feature. The only difference on the physical device I saw was one of the blue lights and writing over top of the ethernet port. V1 used an Earth-arrow icon. V2 replaced the Earth-arrow icon with the letters "NET". Password change: default username / password V1: admin / admin V2: admin / <written on sticker on bottom of ATA> Note: the firmware for V1 and V2 are different links: V1: Release_HT801_1.0.57.1.zip V2: Release_HT80xV2_1.0.3.5.zip Ring Power: V1: Had a checkbox "High Ring Power" V2: has a ComboBox with multiple options: 45Vrms, 50Vrms, 55Vrms Updating the firmware manually in V2 is much faster. The only thing is it gives an error "Reboot failed" but it succeeded. Data-sheet differences: Codecs: V2: added G.722 Pass-through: V1: Short/Long Haul Ring Load 2 REN: Up to 1km on 24 AWG V2: Short/Long Haul Ring Load 5 REN: Up to 1km on 24 AWG Network-Protocols: V2: added SSH, SNMP, IMS/3GPP, IPoE QoS: V2: added Layer 2 (802.1Q VLAN, SIP/RTP 802.1p) Provisioning and Control & Management Syslog support: V2: removed telnet and added SSH Compliance: V2: added K.21

No freakin tech support what so ever. Instructions from an email from Grandstream doesn't match interface. So if your not getting this from a supported reseller that will install and set it up not worth it.. You tubing videos are hit and miss and I mean misses. Sound quality have no idea, Signal have no idea. I thought I had it set up for a month, I had a dial tone, if I called I got busy signal, ok. Well I called my own number and busy signal, basically no connection in/out. So many selections to set it up, you have to have a tech dept specific in voip, Instructions are so generic and brief, you better have courses in setting this up. DON'T WASTE YOUR MONEY OR TIME!!!!

Replaced my Nettalk device with this one and I couldn't be happier. Works flawlessly without issues and sound quality is great. Just the compact size to fit in our room. No drops due to device hangs up given a constant stable connection. Great deal for this device for VOIP calls. Still works over many months for durability.

This is the best single line ATA you can get. It supports pulse dialing and it has a REN of 5 just like the POTS lines did. It works nice with VoIP.ms, which is the best provider in my opinion. This thing is a little difficult to set up, but if you follow a tutorial for the settings to change for your provider it wont be so hard. I have had no issues with this yet. Im glad i chose to upgrade from my cell2jqack to this. My experience with calls have been pretty good. The quality is only bad when the internet is bad. If you have any sort of T-Mobile internet, you will not get this to work unless you turn on TLS on this device and your providers settings. If you use VoIP.ms, they tell you how to change to TLS on their end and on the ATAs end. Conclusion: I’m glad i bought this ata.

With Obihai discontinuing support for its ObiTalk 200 adapters, and with Google Voice connections no longer working with any adapters, I signed up with CallCentric and purchased two Grandstream HT801 units. Easy to setup using CallCentric’s support page. Each unit is in a separate seasonal home with one as an extension on the main CC account. My GV number is added to the outbound caller-ID, and all inbound GV calls ring on the CallCentric number. Works great at both locations. The physical setup is the same as the Obihai adapters. Ethernet cable plugs into your router, and phone plugs into the RJ11 jack. Plug in the power adapter and you’re ready to go. Setup is via a webpage via the HT801’s IP address. You need the settings from your phone service provider. As long as those settings are correct (they were in my case) everything works. With the HT801 and CallCentric, I now have cheap reliable VOIP phone service at both residences.

Works perfectly converted digital line to analog for FAX connectivity. But it works for analog phone lines too.

The Grandstream HandyTone HT801 is a solid and dependable little device. Setup was quick and straightforward, and it worked flawlessly with my VoIP service right out of the box. The build quality feels good, and it’s small enough to fit neatly beside my router without taking up space. Audio quality is excellent — clear and consistent with no dropouts or echo. Configuration options are flexible for those who like to fine-tune settings, but it’s also simple enough for a basic plug-and-play setup. Overall, a great product that does exactly what it should. Perfect for bringing an analogue phone into a modern VoIP setup.

Tired of paying 70 dollars a month for mostly people I don’t want to talk to to try to scam me, sell me some service I don’t need, etc, I looked at options. Keeping the number I’ve had for 30 years, and having a single number that mom and a few others could call and talk to whoever is home is nice. Giving this number to most businesses means that telemarketing calls don’t come to my cell phone. This was the same device used by a 3rd party provider called freephoneline.ca. I decided to try to purchase the device and pay a one time fee to connect with them vs pay a VERY small monthly fee. Everything is working great. Calls are reliable. Device works fine, and by unhooking the telco access at my inside junction, and connecting this to one jack, all of my existing jacks work. The device is great, but I would not recommend this (or any other similar device) unless you have a good support with your provider (I didn’t - but they had an online user forum and this was the device they use) or you are technically strong (30 years in IT). Many people would be better off getting the device with support, through their provider. Setup is easy, but there are 2 or 3 dozen settings many of which need to match your provider, or else you could have no calls, dropped calls, audio but no voice, or other strange things. I was able to get the correct settings online and had it set up and working in about 15 minutes. It has been working great for a couple of months now and I’m glad I did this.
