Good value for the price
This is a “Basic” IP phone, per the vendor, and that’s reflected in the price point. If you expect the device to be on-par with a high-end Cisco or Avaya phone you may be disappointed. However if you want a quality, economical phone with a good feature set then this is a good choice. I found it to be easy to configure, I had it set up in my Asterisk server in under 10 minutes. I was also pleased to see it natively supports OpenVPN, I was able to set up a off-site phone to connect in over VPN without needing to deploy a remove VPN client. It also has support for a LDAP phone book and central configuration, but I haven’t had time to set that up.The biggest things I don’t like are the screen is a bit basic, I’ve noticed sometimes incoming caller ID is truncated. Better than it looking like a flip-phone UI circa 2001 though. An administrative concern is that it is hard to manually update the firmware on this. The firmware is openly available from Grandstream, which is nice, but there’s no option to just upload the new bin file to it. It needs to be set up to a provisioning server, which is just a HTTP server, and the error feedback is pretty much non-existent. Plan to run a syslog and provisioning HTTP server for these alongside your PBX.Overall I am pleased with it. Audio quality is good. I have a Grandstream Budgetone I bought circa 2007 that’s still kicking and it feels like the build quality had improved since then, so I’m optimistic this will last.

Solid VOIP
Good phone, pretty cheap and functions. Call quality is pretty good.

Worked fine until it didn’t
This phone did its job until one day it just stopped receiving the ethernet signal no matter what I tried including the firmware update. Our provider didn’t change nor did our LAN. It is also way too light if that makes sense. A phone needs to be sturdy when sitting on an office desk or it will slide around too much like this one.

For an IP phone it was fairly easy to setup and works well
For an IP phone it was fairly easy to setup and works well. It sometimes would ring randomly but that had to do with accepting incoming calls other than from the proxy. Basically you have to tell your phone not to take calls unless the call routed through your PBX box first, that makes the random calls go away but it is not a problem with the phone but rather people just port scanning on the internet.

Pantalla nunca se apaga
Funciona muy bien, en enlace en las llamadas, la interfaz es muy fácil. Pero la pantalla nunca se apaga. Quiero pensar que es un problema de fabrica.

Great product. Works perfectly.
This product was used as a intercom in a large house along with other phones from the same maker. Works seamlessly with other phones. I recommend it.

Functional, but terrible design
The wires come out of the bottom of the phone, so it won’t sit flat on a table. The plastic base it sits on is machined poorly, so it took a great deal of force and finesse to attach it. Most annoying of all, you have to enter all your SIP config info using the number keypad. They even have a config page you can access with your browser! Why can’t you just type the SIP info there??I did get it working, and the sound quality was fine.

I’ve been using CISCO IP phones for more than 15 years in my office and got absolutely no problem with them. But Grandstream at this pricing was a much cheaper option. I found the Grandstream phone to be much sleek and as efficient. It was much much more easier to configure as compared to Cisco. We have decided to slowly replace all our phones with this brand. Even the seller was very supportive.

音質、遅延が少し気になるがIP電話だとこんなものなんでしょう。品質は悪くないです。バックライトの消し方はわかりずらかった。
