After setting up several of these phones we are very impressed. Set up using the user interface is very quick and easy, even to use provisioning is easy. Button configuration is also very easy, our receptionist managed to program all her buttons not using the manual.
Call quality is the best I have ever heard, the first time we used one of these to our customer who also has these the customer thought the call kept dropping because I was listening to the quality of the call instead of what the customer was saying. I really like the way the phone displays the weather, our office has no windows so this feature is really brilliant.
All in all a very good phone with few problems, the only problem we have is one of these phone occasionally crashes on hangup but this is easily fixed with a reboot need to investigate further just not had the time yet.
