[Asterisk-Users] Stay away from Grandstream!

[Elene Kinsky]

Yes, our mistake that we make order directly from GS. Should make via 
some reseller instead. About rate: 2/11 phones dead.  Regarding the 
phone quality, it looks a bit cheap (I know it's really cheap), some 
buttons are worn out after few months of intensive use.
Now maybe we'll consider to buy other phones for our customers.
