Review: Works with Vonage or between two landline telephones - no phone network required - 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.
Review: Works with FreePBX! - Leaving a review because none of them seemed to mention that this works great with FreePBX. I am in no way a VOIP/PBX expert so I struggled to find instructions on how to get them working together. I also discovered that there must be a password length limitation on the Grandstream as it failed to register until I set a shorter device password/secret (FreePBX logs showed failed to authenticate). To get this working with FreePBX In FreePBX: 1) Applications > Extensions 2) Add Extension > Add New SIP (chan_pjsip) 3) Pick your extension number and set a Secret that is less than 14 characters. 4) Take note of the banner at the top indicating what Port your PJSIP is listening on (default 5060 UDP) Log into the Grandstream Web UI using the device IP address (default login is admin/admin) 5) Click FXS Port 1 or FXS Port 2 at the top 6) For Primary SIP Server, enter your FreePBX IP address AND the port (192.168.1.10:5060) 7) Scroll down to SIP User ID and Authenticate ID, enter the extension number from step 3 above 8) For Authenticate Password, enter the Secret you set for the extension. 9) I also set my Primary DNS IP (probably not necessary if you use DHCP) 10) Scroll to the bottom and click Apply. After that, on the Grandstream Status page you should see your FXS port as Registered after some time. You might need to reboot the device. Obviously repeat all steps for the other FXS port. If you google the Granstream model number their website has a PDF document that explains what all the options are within the configuration.

## Questions & Answers

**Q: Ate you able to send & receive faxes from a fax machine  connected to the HT-802? If so what special configuration for faxes?**
A: Yes, it can be done if your VoIP provider supports it.  We have VOIP.ms and they require customers to set up a fax specific line to send/receive faxes.  Faxing worked well when we had that feature.

**Q: Can you configure one Jack for regular touch tone dialing and the other for pulse individually?**
A: Yes you can, "Enable Pulse Dialing" appears in the configuration for each line.

**Q: Is this gismo what i need to connect gxp 2170 phone to a land line??????????????**
A: No - this connects a regular phone to a VOIP server....

**Q: Can this device work with magicJack plus?**
A: MagicJack *Plus* is a device intended to connect to the Internet - typically on a LAN port on your Internet gateway router. It already has a standard RJ-11 jack for a standard PSTN phone. This box shouldn't be required for that, unless you intend to replace the MagicJack Plus box with this one. If that's the case, you'd best call MagicJack and ask them - or just get a MagicJack box that would perform the same gateway function as this adapter would - and be much less problematic to get working properly with the MagicJack service.

### ⭐⭐⭐⭐ Great option for cheap landlines if you are a little tech savvy
*by F***O on October 14, 2017*

This is a great little device that does not try to dumb things down for users, as it offers a huge number of options. It works great with both of my deep discount VOIP providers, Anveo and Future-nine, thereby giving me "DIY" landlines for well under $100/year. Of course, if you want the reliability of a standard landline, you will need to put this device, your router, and your modem onto a UPS--but again that's a modest upfront cost compared to the monthly cost of most full-service analog landlines. There are a few drawbacks worth mentioning, however. One is that to update the firmware from Grandstream's web site, you must use an http, not an https URL. That seems a bit backwards for 2017, and suggests the company is not very security conscious. In fairness, the device offers complete control over the update URL, so you can also download firmware from a machine on your local network including over https. Obviously the device is targeted for enterprise users (which I am not), who will want to roll out configuration and updates from a central internal server. The second problem I had was that my phone would start randomly ringing or just emitting weird partial rings, with seemingly no caller. Upon looking at a packet trace from my border router, it turned out the Grandstream was being attacked remotely. Though the Grandstream is behind a NAT, I had configured the device to use UPnP, which made it open a port to the outside world on my router. I don't think any of the attacks were actually succeeding in doing anything, but it was annoying that they made my phone ring at odd hours. An easy solution was to configure the Grandstream to use keepalives instead of UPnP for NAT piercing. In fact, I'd initially used UPnP because I thought keepalives might not be reliable enough for incoming calls. However, the keepalives work great and prevent random outside IP addresses from messing with my Grandstream. Since keepalives are the easiest option to set up, this is really just a result of my overthinking things. But again, they don't inspire confidence in the device's security, so really only consider using this on a secure network.
