NextGen Calling

Overview

NextGen Calling is an AI-powered voice calling platform where intelligent agents handle calls autonomously. Businesses upload a knowledge base — product docs, FAQs, policies — which the AI ingests and uses to answer caller questions, qualify leads, and route escalations in real time.

Twilio media streams feed live audio through a speech-to-text pipeline that transcribes conversations in real time. A FastAPI backend orchestrates agent logic, manages call state in Redis, and exposes a React dashboard for configuring workflows, reviewing transcripts, and monitoring call performance.

Key Highlights

  • Knowledge-base document ingestion powering AI agent responses
  • Dynamic call workflow builder — define branching logic without code
  • Real-time speech-to-text transcription via Twilio media streams
  • Redis for live call session state and agent context management
  • Inbound and outbound AI call handling with escalation rules
  • React dashboard for workflow configuration, transcript review, and analytics
