When I use Audacity to record greetings for Unity Call Handlers, I can export them as WAV 16-bit. I can upload the file and it plays successfully. If I do the same for a CCX prompt, it does not play - just noise is heard. I've ended up downloading an existing prompt, such as 7333, renaming it to 7334, upload that and re-record the greeting with the Call Center Maintenance line, then delete and rename the prompts accordingly for the new one to be in effect.
I've tried different formats using Audacity to record prompts, I wonder what format I should be using for CCX?
