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.
After I plugged the power adapter and Cat 5 Internet cables into the bottom, I saw that they stick out past the snap-on stand and make the phone wobble badly. Until I have a better solution, I use a thick book on which to rest the rear half of the phone. This is not perfectly stable and is ugly, but I will find cables with 90-degree plugs or make a better-shaped platform.
The VoIP.ms service worked well early on, but Call Centric took weeks (including time off for frustration relief) of experimental configuration settings. I needed to use the online documentation by Grandstream (GS) and both voip services to get the work done. GS challenged me with different terms for certain things than I expected, and I never saw a glossary. For example they used PCMU as the name for a codec, which was okay except the services used another name for it, G711u. Neither mentioned the alternative name.
Allow for a long learning curve if you don't have a head start in VoIP terminology. I had a head start, having programmed Obihai and Lynksys ATA devices and was still blind-sighted. Good luck--I proved the concept and you probably can too! :-)
