It's been a while, but my issue with Grandstream has always been:
1) SIP interoperability & stack problems.
2) Low-end speaker phone hardware, thus bad echo cancellation and duplex handling.
I am not a speakerphone user myself, and most of our customers are not. Every now and then we get one that doesn't like the SPA phones, and probably wouldn't like the Grandstream either. We give them a Polycom.
The Grandstreams from a few years ago gave us a lot of issues on SIP and provisioning, but that's gone as far as we've seen. I originally turned down the offer of some demo phones based on past experience, so I urge everyone to discard that experience and see it as a new product.
I mainly judge phone hardware by the quality of its speakerphone, since I'm a very heavy user, so it may be a personal bias. However, by that metric, the Cisco 79xx's and Polycoms win, and Grandstreams, Snoms and Aastras lose.
Yeah, I'd never use speakerphone when talking to anyone, so user type will be important here. I always recommend a headset to the speakerphone users, about 50% go for it. When co-workers 10 feet away from me insist on using their speakerphone, I want to beat them senseless. Therefore I need a nice heavy phone that will take a lot of abuse.
