Integrate Voice AI with ChatGPT in Seconds
Integrate conversational voice agents using ChatGPT with custom agent prompt engineering. Effortlessly equip your project with low-latency (450–600 ms) conversational telephony simply by copying and pasting the master prompt below into ChatGPT.
The prompt contains complete knowledge of the Vistara Connect REST API, low-latency Hindi telephony defaults, voice agent craftsmanship guidelines, and an automated flow to trigger a live test call to your personal mobile phone.
Coding agents work best with the file: save it in your project (for example as VISTARA.md) and ask ChatGPT to follow it.

What Happens When You Paste This Prompt into ChatGPT
Account Verification
ChatGPT asks if you are registered at app.vistaraai.in. If new, it guides you through phone OTP sign-up — ₹150 free credit with GSTIN (₹50 without) — up to 200 calls, since unanswered calls are never charged.
Agent Query & Selection
Uses your API key to list your existing voice agents. You can pick an active agent or let ChatGPT construct a brand new dedicated persona.
Voice Prompt Craftsmanship
Constructs a 10-section prompt with native Devanagari Hindi spoken text, phone conversation mechanics, objection handling, and CRM deliverables.
Live Phone Test Call
Asks for your mobile number and dispatches a priority test call (x-call-type: test). Your phone rings immediately so you experience the AI conversation live!
Codebase Scaffolding
Scaffolds clean outbound call dispatchers, webhook receivers for post-call transcripts, rate-limiting guards, and .env files directly in your repository.
Under the Hood: Vistara Connect REST Architecture
Everything ChatGPT will wire up into your backend application:
Programmatic Agent Management (GET, POST, PUT /api/v1/agents)
Manage conversational agent lifecycles via REST. Agents default to Hindi with native Indian speech synthesis (meera or Aoede).
