IVR Editor is a visual IVR flow editor that supports drag-and-drop menu design, business hours control, TTS voice synthesis, and multi-level menus.

1. Enable

[proxy]
addons = ["ivr-editor"]

Database requirements: automatically creates rustpbx_ivr_projects and rustpbx_ivr_version_history tables. Supports SQLite / MySQL / PostgreSQL.

2. Project Management

2.1 Create a Project

Console → IVR Editor → New Project:

• Name, description
• Status: draft / published

2.2 Version Management

Each publish creates a version snapshot with rollback support:

• View version history
• One-click rollback to a previous version

3. Visual Editing

3.1 Node Types

3.2 Editing Flow

1. Drag nodes onto the canvas
2. Connect nodes (DTMF key → target node)
3. Configure parameters for each node
4. Set business hours rules
5. Preview and publish

Each project can configure:

4. TTS Voice Synthesis

4.1 Built-in Edge TTS

Uses Microsoft Edge TTS (edge-cli tool) for voice synthesis:

Supports 11 voices:

4.2 TTS Cache

TTS results are cached to a local directory by SHA-256(voice+text) to avoid redundant synthesis.

4.3 Manual TTS

POST /console/ivr_editor/tts
Body: { "text": "欢迎致电", "voice": "zh-CN-XiaoxiaoNeural" }

4.4 Audio Upload

Supports uploading custom WAV/MP3 audio files as IVR prompts.

5. Publish Flow

1. Click Publish after editing
2. The system automatically:
   • Builds IVR TOML configuration
   • Generates all TTS audio
   • Saves version snapshot
   • Writes to the configuration directory
3. RustPBX hot-reloads the new IVR configuration

6. Configuration

config/ivr_editor.toml:

sounds_dir = "config/sounds"
ivr_config_dir = "config/ivr"
tts_cache_dir = "config/tts_cache"
