You want MiRTA PBX to call an extension or external number and record the spoken audio from that call.

Demo records
The Canistracci OIL tenant contains these documentation examples: Docs Demo IVR Upload Prompt, Docs Demo IVR Menu TTS, IVR selection, and Some music.
Deleting records
Before deleting a media file, check every call flow that can reference prompts: IVRs, queues, DISAs, hunt lists, custom destinations, music-on-hold lists, and standard messages. MiRTA PBX asks for confirmation before the delete is submitted.
