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.
