How To Use
- Twilio Webhook Setup: Configure the 'Twilio Voice Webhook' node with your desired path (e.g.,
/voice-webhook). This URL will be used in your Twilio voice application. - OpenAI API Configuration: Provide your OpenAI API credentials. Customize the 'OpenAI GPT-4o Response' node's system prompt to align the AI's persona and capabilities with your specific business needs (e.g., appointment types, order items).
- ElevenLabs API Integration: Set up your ElevenLabs API credentials. Select your preferred
voice_idand adjust voice settings within the 'ElevenLabs Text-to-Speech' node for optimal audio quality. - Twilio TwiML Responses: Ensure the 'Twilio TwiML Response' and 'Initial Greeting' nodes correctly reference the webhook URL (
{{ $node.webhook.getWebhookUrl() }}) for continuous call flow. - Audio Hosting: The 'Upload Audio to Storage' node is critical for making ElevenLabs generated audio playable by Twilio. Configure it to upload the audio to a publicly accessible storage and ensure it outputs a URL (e.g.,
audio_url) that the Twilio TwiML can use. - Google Sheets Integration: Provide Google Sheets API credentials for the 'Log Conversation' and 'Save Appointment Request' nodes. Replace placeholder document IDs (
your-google-sheet-id,your-appointments-sheet-id) with your actual Google Sheet IDs for data logging.
