Right, I've installed my 2nd UC520 and this time it seemed to go a lot smoother than my last one :). Then last night this lovely problem appeared. When trying to load Voice Data within the CCA 2.0.(1) It just fails to load anything, the box will appear on my screen and then just sit there and won't progress onto the Voice GUI. The system is now 150 miles away from me so I'm not in a posistion to restore the system to factory defaults and start again.
