I think Alex is pretty close to customer reality here, where there is a perception of quality when the handset feels solid and has a rich, robust sounding speaker phone, and that perception of quality then reflects onto the provider that supplied the phone. I have tens of thousands deployed grandstream devices, but they are all ATA's and I have been happy with them, however on the IP phone side of things we are still mostly a cisco SPA 5XX shop because of the perception of quality and the far lower quantity of corner case / protocol issues. The Sipura / Cisco SIP stack is pretty much the gold standard for SIP endpoints, and the pricing of the Grandstreams have not yet beat out that reliability.

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 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.

Who else on the list is using them, particularly in a hosted environment? We've just decided to transition to them as our primary recommendation instead of the Cisco SPA series. We did it because of the value and feature set, like having an inexpensive phone with a small BLF, which a lot of customers asked for. I'm wondering if others have tips they've learned along the way, or any advice they want to offer. Also anyone using the advanced features like the browser for anything useful?
For those who haven't tried them, or who like us, didn't like their older models, take another look. We have been surprised at the value they give us. The prices are low, but the functionality and quality are high. They aren't Polycom 600s to be sure, but they are nice phones that have a huge set of features for a great price. Customers are liking them a lot.
Has anyone used the new DECT phone? We currently use the Panasonic DECT phones but they are a nightmare to configure.
If anyone wants to get in touch with them, our Grandstream contact is Dennis Ryan, dryan at grandstream.com <mailto:dryan at grandstream.com> .
