Prompts Module Overview
The Prompts Module allows UCS to play pre-recorded audio announcements within a call flow. Prompts form the dialogue structure, guiding callers with relevant instructions, such as:
- "For operator, press zero."
- "Good morning, you have dialled..."

✔ Prompts can be recorded as human voice files or generated via Text-to-Speech (TTS)
✔ System Prompts (fixed, numbered 0-999) cannot be renamed or deleted.
✔ Application Prompts (numbered 1000 and above) can be freely defined and removed.
✔ Multi-language support:
- System Prompts are available in multiple languages.
- Application Prompts require dedicated language directories.
✔ Supported File Formats:
- ccitt u-law: 8kb/s, 8kHz, 8-bit, mono
-
PCM: 8kHz, 16-bit, mono
Other formats will crash VoIP media!
