I can not get CUCM to play the ringback.wav file for MOH. This file was downloaded from UCCX (g711 version). All other MOH files work fine.
There were no errors while uploading the file to CUCM, the MRGs and MRLs are configured correctly, the phones and MOH server have been reset...I don't know what else to check.
The only thing that is different about this WAV file, compared to the ones that work, is the length. It is only 5 seconds. Is this some type of CUCM bug?
Does anyone have a ringback.wav file, other than the one that comes with UCCX?
I am sure you have already checked this probably, have you uploaded the file to every server in your cluster (every one that runs MOH service ?)
