I have a UC520 running IOS 12.4.22(T) and CME 7.0(1) which I have upgraded a number of times to get here. But I just noticed that the CUE is still at version 3.0 and I need to upgrade it to latest version. I have read about the CCA and that it could not be the perferred process. Any advice on how to upgrade the CUE to that lastest version?
The UC520 is the 48 phone model.
