Grandstream IVR (Interactive Voice Response) systems typically use audio files in formats such as WAV or MP3. The most common format for these systems is the WAV format, often with specific requirements like a sample rate of 8 kHz and 16-bit PCM encoding to ensure compatibility and optimal performance. Always refer to the specific Grandstream device documentation for precise format requirements.
