The Problem

Voice AI costs enterprises too much — or locks them into foreign vendors

Most enterprise voice AI platforms charge $0.60–$1.00/minute when you stack Twilio, ElevenLabs, and a cloud LLM. Enterprises pay a currency premium on top of that. The result: voice automation that costs more than the human agents it was meant to replace.

Our Approach

Self-hosted, carrier-native, cost-engineered from the start

  • ◆Airtel + Jio SIP integration — no Twilio, no international call routing overhead
  • ◆Deepgram STT/TTS — low latency, enterprise-grade, no ElevenLabs dependency
  • ◆LangGraph stateful agent graphs — complex multi-step conversations handled correctly
  • ◆n8n orchestration — connects voice agent to your CRM, ERP, and ticketing systems
  • ◆Self-hosted LiveKit for WebRTC — no LiveKit Cloud dependency, data stays on your servers
  • ◆Grafana + Prometheus observability — every call logged, latency monitored, errors alerted
