Do you need to have an audio device on the server for the custom audio prompts to play? I've added an audio prompt to a digital receptionist. And it doesn't play when I phone the number that has the digital receptionist on it. It's as though it can't play the file and then skips it, yet the 3cx ones will play. I have checked the server side and it seems that there is no audio devices installed (because there are no hardware audio devices on the server). Would this affect the prompts not playing?
