Plivo & UltraVox AI Voice Call Session Automation

This n8n workflow integrates Plivo telephony with UltraVox AI to seamlessly create and join AI voice assistant call sessions. When Plivo initiates a call and hits the webhook's Answer URL, the workflow instantly creates an audio stream session on UltraVox using a POST request to their API, configured for Plivo medium. It then responds with Plivo-compatible XML instructions to join the session, allowing real-time AI interactions.

Key benefits include effortless setup for AI-driven phone automation, reducing manual intervention in call handling. Users save hours on custom voice agent development, with customizable system prompts for specific business needs like clinic bookings or info queries. The workflow supports voices and prompts tailored for natural conversations, enhancing customer engagement without coding expertise.

Ideal use cases span customer service for clinics, sales hotlines, or virtual receptionists. For instance, configure it for a physiotherapy center to handle appointment queries during off-hours. High scalability for businesses needing 24/7 AI voice support, with easy credential updates for UltraVox API keys and prompts. Includes YouTube demo for quick onboarding.
