Review on Skype for Business Edition Polycom VVX 601 by Alvin Peoples

Can't get this to work with the Vonage system. I unplugged the old model phone and plugged it into this one, there is no beep. No instructions. Not a very good plug and play or user friendly interface. I called the manufacturer, they don't make this phone anymore so they don't support it. Revain washes hands after 90 days. We were too busy to focus on why it wasn't working and missed the return window. I thought it was us, not the phone. We can be, but nobody will support us in this matter
