We are very happy with most Grandstream products we work very closely with 
their engineering and support guys they are very good about getting us new 
features and bug fixes, and yes like most VOIP hardware they do have lot's 
of bugs but they actually fix most of them. 

The only current products I don't recommend from them right now are the 
GXV-3175 (Slow processor and very buggy firmware), GXV-3000 (Has a handset 
mic overdrive issue. Have to add a resistor to the inside of the handset). 
I am holding on the new Dect DP715 for the next firmware rev (it is a good 
product at a fair price but several firmware bugs are show stoppers. We are 
awaiting beta fixes sometime next week and then we will start shipping 
them)  Hope this helps.
