2-FXS Port Analog Telephone Adapter (HT802)

I use this with my own PBX and a fax machine that only gets used once or twice a year. Setup was straightforward, and it has been reliable for keeping that analog device available on my VoIP setup.

Works great- but a BEAR to learn how to MAKE it work! There's ZERO customer support from Grandstream, so you have to figure out the 'techy' details yourself to install it correctly to make it work- just pay someone to install it for you that DOES 'techy' stuff like this. Believe me, if you aren't in IT, this is a pain in the butt to get up and running, wiht no one to call to walk you through how to do it!

This is a good product and value. I have two of them and have not had any problems. I have tested with multiple VOIP ptoviders and the sound is fine. It looks cool and has taken a couple of falls without damage (magnet mount to wall). I have two and durability hasn't been an issue. The UI is a bit dated but works fine. It times out too quickly but has dozens of options. I use two for SOHO but the number of options could lean towards enterprise. I have not had anyone complain of lack of clarity.

Background information: OBiTALK discontinued, on 6/7/2022, support for a variety of Obihai devices, including the OBi110 that we have been using as our VoIP ATA. As the result, we no longer had VOIP service from Anveo for our telephones and fax machine. We had been using our OBi110 for years, for both voice and fax communication, with our Anveo obitalk account. In particular, our fax machine worked fine with this set up. Based upon information from Anveo. we purchased the Grandstream HT-802 as a replacement for the Obi110. I was not able to obtain detailed open print or even sufficient) information anywhere 2 get the HT-802 to work with my Anveo account. It turned out that there was no way to get the HT-802 to work with my Anveo Obitalk account. With significant (and exceptionally good) assistance from the Anveo support rep, was able to get the HT-802 to function, however, it turns out that the HT-802 likely does not support fax communications, even at the reduced speed VoIP communications rate configuration of the fax machine, 9600 baud. By the way, Grandstream does not offer support for the HT-802. You may be able to obtain some support from the Grandstream online forum, however, if you do receive responses to your questions , the responses may be slow in coming. Outline of setup/configuration steps: Note: the following assumes that you have using Anveo as your VoIP service provider. If you have been using a different VOIP service provider, the following, in all likelihood, does not apply to you. 1. The first thing that you are going to need to do is open a support ticket with Anveo, as many of the steps that are required to convert from and Obitalk account using an OBi110 to “regular” Anveo account using a Grandstream HT- 802, require Anveo to implement. 2. Ask Anveo to convert your oi talk account to a “regular” “free” account. Ask them to credit the unused dollar amount portion of your obitalk account back to your account so that you can use for your “regular” account. 3. You may need to change your IVR/Call Flows to the default call flow. (My call flows that worked with obitalk/OBI110 no longer functioned correctly with the HT-802.) Anveo support can make this change for you. 3. Log into your account at Anveo: 3a. Note your Anveo account number. This is your SIP User ID 3b. In “SIP Registration Details: Note the part that follows the “@”of your SIP URL. Mine was “sip.anveo.com:5010 “ You will need this to configure the HT-802. 3c. In “SIP Registration Details: Note your password. You will need this to configure the HT-802. (The SIP password is assigned by Anveo and is not the same as the password to log in to your Anveo account. 3d. In the Call Security menu, increase “Block calls with call rate more than” to $0.04 4. The only screen that I had to configure at the webpage for my HT-802 was at the FXS1 tab. My configuration was as follows: Summary of FZS1 configuration for Anveo for the HT-802: Primary SIP Server: sip.anveo.com:5010 SIP User ID: your Anveo account number Authenticate ID: your Anveo account number Authenticate Password: your Anveo SIP password Name: Your name Maximum Number of SIP Request Retries:4 SIP T1 Timeout: 1 sec SIP T2 Interval: 4 sec 5. After you have configured the HT-802, the Status tab should show Port Status = “Registered” 6. After your HT-802 shows the status as registered, verify the following: 6a. Ability to make outgoing telephone calls. Note: You will need to add a one at the beginning of the telephone number that you are dialing. Example: 1-123-456-7890 6b. Ability to receive telephone calls. Note: the ringing that the calling party hears may have second ring delayed by a few seconds. This is normal. 6c. The following applies if you were paying Anveo for the optional E911 service. Make a test call to your local 911 and verify that they have the correct address for you. 7. For sending and receiving faxes, plan to use the functionality from your Anveo account as your fax machine will likely not work with the HT-802. Good luck!

Do not use anything from Grandstream. This came with no user manual or instructions. I got Ring Central to help me and we got to a place where we needed a password which was supposed to be on the device. The # did not work. To get help, I had to jump through hoops and answer questions that were not relevant for hours. After five hours now, I have to wait another 24 hours for an answer! I tried Amazon and they also could not help me except to give me Grandstream's website. Horrible customer service!

I had a Cisco SPA112 analog telephone adapter (ATA) with Vonage for many years. People on the other end started hearing themselves as an echo. After many phone calls to Vonage customer service and 4-5 hours wasted talking to them, I decided to purchase the Grandstream HT802. I called Vonage and had them remote into my laptop to configure the HT802 to work with their network. After a reboot of the device it's been working fine ever since with no more echo issues. You can also configure the HT802 to make "offline" calls between two landline telephones - no phone service/network required. This could be used like an intercom between two phones in the same house or building or between a gate and a house/building. To see how to do this, search for "Make Offline Calls Between Landline Telephones - no Phone Network" on YT.

Well, all good things come to an end, and the writing is on the wall with the Obi202 reaching end of life in December 2023. Rather than wait for things to just suddenly stop working someday, I decided to sign up for outgoing service through CallCentric and use this officially supported box. I'm glad I did. I have used my Obi202 and Google Voice for what feels like 15 years now. Free phone service has been great, except for $2/month for an incoming number through CallCentric that gave me e911 service and caller ID. However, people would often complain that they couldn't hear me that well over the past 2 years. I decided, with the announcement of Obi202's retirement, that I would sign up for CallCentric's outgoing plan and pair it with this box. Using the instructions on CC's site, I configured this box as instructed and immediately had service within minutes. I made a few test calls, and everything worked great, including my outgoing caller ID showing up as my Google Voice number, which CallCentric can do for you. This box helps me get much better sound quality than I had with the Obi202 + Google Voice combination. People on the other end of the phone say they notice a big difference when talking to me now, which is great. I don't mind paying a few bucks more every month for reliable, quality phone service at home. This box was a great deal under $40 and I will recommend it to friends and family.

I bought this to use with voip.ms The unit itself seems pretty solid, no dropped calls so far, sound is good. We have it set up on a expanded cordless system. The only thing I would mention as a few others has, is to pay attention to the port you plug the phone into. You think your plugging it into port 1 then spend a few hrs wondering why nothing works after you get it hooked up to voip.ms or similar site, only to finally realize after begging and pleading with AI to give you an idea of what went wrong lol, and it comes up with "have you tried switching ports". That moment you laugh at AI for being so basic its stupid....till it works lol. Far as setting it up with a server like voip.ms it was my first time doing it. I have pretty decent tech skills but it was still a bit challenging for me. For certain parts. But if you know how to use AI it will eventually get you through the process. I know my grandmother couldn't do it lol but for the average person if you got average tech skills it shouldn't be too bad. We have tried so many other things like x-link (just don't) darn thing dropped calls every 20 min and I tried everything with that even bought a whole new set of phones thinking that was the problem. I tried phone through cable company (that was a joke, phone wouldn't work for days till family members would call cell and I've have to restart the modem). Tried those cellular "home" boxes that allow the phone to run off cell signal, also a joke after spending $100 on one same issue as cable modems. And I had to have something as my mother has memory problems and cannot use cell phones, and the landline to her house was cut underground several years ago. This grandstream has been great, only thing that has been reliable so far.

Concurrent direct du SPA112 de Cisco. • Fonctionne beaucoup mieux que le SPA (j'en avais un pendant 2ans, je l'ai détruit à la masse...) • Ses connexions sont stables et rapides. • J'apprécie quelques options fondamentales en plus comme par exemple le fait de pouvoir couper l'appel sortant au bout d'un certain temps pour éviter des hors forfaits. • Il ne redémarre pas non plus à chaque fois que l'on fait une modification. • L'interface est plus simpliste que le SPA, ce qui peut rebuter. Ne pas tenir compte de cela. C'est exclusif (ça mérite un vote utile ☺), je vous donne les points clé de config de ligne pour le faire marcher. (et si ça marche pas vous n'êtes pas loin). Cette config est pour un téléphone. Account Active: Yes Primary SIP Server: SIP User ID: Authenticate ID: Authenticate Password: Outgoing Call without Registration: No Dial Plan: {[x*]+} (info: ce paramètre est en cause si réceptionne call mais compose et n'émet pas) SRTP Mode: Disabled SLIC Setting: European CTR21 Caller ID Scheme: ETSI FSK prior ringing with (LR+)DTAS Outgoing Call Duration Limit: 59 (évite surfacturation >1h, dépend de l'opérateur)

設定は、インターネットにあった先人達の情報をみてやりました。想定通りつながりました。 これと、wifi受信機を複合機をセットで組み、どこにでも据え付けできるようになりました。もっと早く買えば良かったです。

Por fin he encontrado un dispositivo que permite usar el teléfono (encapsulado en VLAN) en una conexión de fibra. La interfaz web es un poco lenta, pero tiene múltiples opciones y se pueden introducir las credenciales SIP sin problema. Muy recomendable.

Grandstream GS-HT802 was delivered today, the seller is ThePhoneGuy-Canada. I mention the seller because technical issues and technical support issues, as seen in this comment section, seem to be seller-specific. In my case, the first issue came immediately, HT-802 web interface did not want to accept user name admin, password admin -- these default names are stated in every Manual available in the Internet and on the Manufacturer site. I set a ticket at the Grandstream tech.support and get a response within 30 minutes - "Look at the bottom of the device", this solved the problem. Again, based on comments in this ection and elsewhere, I expected no response for days or empty response -" go for support to the seller". After the issue was solved, a configuration process went smoothly - I used a Wiki at VOIP.ms, which is my current provider. Within 30 minutes I was able to make calls, the quality of calls was better compared to my conventional land line. Summary: - tech.support was very fast - sophisticated configuration was smooth (use proper help!) - initial impression about the quality of calls: great! Obviously, the reliability of the device is very important, so, I will come and update this review "if/when"

brought this to connect SIP to my analog pbx works without any issues
