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.

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.

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.

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.

Phone is fine. It's definitely not plug and play, which means you have to sit on the phone for a bit which is slightly annoying but somewhat expected. My only complaint is the handset is SO SLIPPERY! I keep dropping the phone because it slips out of my hand.

The phone works fine when you use the power supply that is included. Although when trying to use POE from this vendor it seems all the phones I have gotten do not power on. I have no idea why specifically from this vendor the POE functionality does not work but that is the case. Otherwise it works fine.
