Hello, I am testing Axon PBX. When I call extension 101 (configured with internal voicemail system) from another extension, it produces 3 rings, then the call is answered, but there is no voice prompt. Nevertheless I can leave a voice message. Then when from extension 101 I call 500, it rings one time, but the recorded voice message is not played back. I am doing something wrong? I have to install necessarly IVM Answering Attendant? I can´t find this option: The Voice Prompt Settings can be found in the application Options under the "Prompts" tab. This tab displays a list of all the voice prompts that are used by Axon for various interactive features like the internal voicemail system. From this list you can listen to or change any of the voice prompts.
