We are currently investigating several cases where UC560s running on the latest SWP 8.0.4 are experiencing Audo Chop and distortion with Voice Mail Greeting & Recorded Voice Mail Messages.
We believe we understand the issue now is with CUE 8.0.2 and are close to implementing a solution
Please watch CSCti85760 in your Bug Toolkit for status.
In the mean time if you do experience this issue, use CCA to reload CUE (we have seen this help when the problem occurs and found very agressive proactive action of every 2-3 days will prevent this).
If you have a factory UC560 ready to install, please only upgrade the IOS to 15.0(1)XA3A. Do not upgrade CUE (Stay with CUE 7.1.3)
We removed the UC560 SWP from CCO until we have a solution.
*If you need 15.0(1)XA3a IOS image, you can get it from 8.0.4 software pack for uc540 platform which is still posted and has no problem.
NEW INFO:
Downgrading is NOT an option for CUE. DO NOT attempt to downgrade CUE to 7.1.3 if you are running CUE 8.0.2 as it is not supported.
