First off, if you are in the US, I would definately discourge using "911" as the autoattendant number. Because of using that number, the system may not be saving your changes, I am not sure about that since I have never tried using that number before.
Have there been any changes made to the system with CLI? Some changes will effect CCA from being able to communicate with CUE.
Do you get an error message when applying the configuration? Is CUE running/responding? I would first suggest running the CUE diagnostics under the "Troubleshooting" section of CCA.
It sounds like the changes are not being saved for some reason. Can you make changes to Voicemail, and do they save? This would verify that CUE is saving changes made in CCA. There are a number of little things to check, but I would probably suggest opening a case with TAC, that might be much faster than trying to go though everything here.
