Grandstream GS-HT802 2 Port Analog Telephone Adapter VoIP Phone & Device, Black

This is a fantastic little device that doesn't try to simplify things for users and instead provides a plethora of choices. It works perfectly with both of my low-cost VOIP providers, Anveo and Future-Net. I now have nine "DIY" landlines for well under $100 per year. Of course, if you want the same level of reliability as a traditional landline, you'll need to connect this device, as well as your router and modem, to a UPS. However, when compared to the monthly cost of most full-time jobs, that's a small upfront cost. analog landlines are serviced br>br>However, there are a few disadvantages to be aware of. One is that you must use an http URL rather than an https URL to update the firmware from Grandstream's website. This appears to be a step backwards in 2017, and it suggests the company isn't particularly concerned about security. To be fair, the device gives you complete control over the update URL, so you can get firmware from any machine on your local network, including via https. Obviously, the device is aimed at enterprise users (which I am not), who will want to manage and update their devices from a central internal server. br>br>The second issue I had was that my phone would start ringing or emitting strange partial rings at random times, with no apparent caller. It was discovered that the Grandstream was being attacked remotely after looking at a packet trace from my border router. Despite the fact that the Grandstream is behind a NAT, I had set it up to use UPnP, which allowed it to open a port on my router to the outside world. I don't believe any of the attacks were successful, but the fact that they made my phone ring at odd hours was annoying. An easy solution was to configure the Grandstream to use keepalives instead of UPnP for NAT piercing. In fact, I started with UPnP because I was concerned that keepalives wouldn't be dependable enough for incoming calls. The keepalives, on the other hand, do a fantastic job of preventing my Grandstream from being hacked by random outside IP addresses. Because keepalives are the simplest option to set up, this is simply a result of my overthinking. However, they do not instill confidence in the device's security, so use it only on a secure network.

br>br>I tried it for a few weeks, but it's inability to do10- It's extremely inconvenient to dial by numbers. Yes, I could eventually train myself to dial 1 every time, but why would I want to do that? I decided to give it to charity and replace it with the Cisco SPA122, which is similar in size and price. It's simple to set up a dialing rule that adds the 1 to all 10 digit numbers, making 10 digit dialing a breeze. Grandstream has no plans to do so, which is frustrating, annoying, and inexplicable given how simple it would be to do so. The incredibly complex logic could be deciphered by a first-year junior programmer. [if 10- Add 1 to the front of the digits! ]br>br>Aside from that, it works fine, but the support documentation is lacking, and the interface appears to have been updated in the last decade or two. br>br>Unless you have a compelling reason, the Cisco should be your first choice.

***THIS PAGE HAS BEEN ADDITIONALLY UPDATED*** ***NOTE: THIS PAGE HAS BEEN REVISED. I recently reduced the number of stars from five to two. br>After only three months, my second HT802 has failed. It would occasionally be disconnected in the morning, with the LEDs flashing. It could be reset by power cycling, but it would recur. A factory reset was recommended by Tech Support. That didn't make any difference. They requested that I provide them with more tekkie reports, as I had done previously - and, as before, I politely declined. I am unable to use Grandstream products in the future. __________br>__________br>__________br>__________br>__________br>__________br>__________br>__________b Until we experienced a power outage caused by a large power surge. Even after Callcentric instructed me to perform a factory reset, the unit was unable to recover.
