We note that a correctly formated WAV file on the UCCX, when played back as a prompt, seems to have a very high SISSSSS sound. The same played back on CUCM is much improved. This is a Version 9 UCCX and we are wondering if anyone has had this issue and how you might have solved it. It makes the speaker sound like they have a problem pronocing S's!
I have this problem too.
