I have a problem here with MOH. Currently, the version of CCM we are using is 4.1(3). We are using a new MOH audio source file which we uploaded 1 year ago. It was working fine.
However, when we try to change to a new MOH file recently, there are no error during uploading. And when we swing to the new MOH file, it is working fine for ard 1 week. But after that, when we put on hold, we do not hear anything from the MOH.
We try to swing back to the old one, its works perfectly well. A few weeks later, we swing to the new, its looks fine for a few days, afterwhich the same thing happen again.
Anyone can advise.
