This workflow template creates an audio stream session on UltraVox compatible with Plivo and sends it to Plivo. How It Works : Plivo initiates a call and requests the Answer URL. The workflow responds with Plivo XML to join the session. Note: Ensure you update the UltraVox API Key in the credentials. Update System Prompt based on your requirements.
