DevConf.IN Pune is here - February 13-14 - and the Exotel Developer Network is showing up with a hands-on workshop where you’ll walk in with a laptop and walk out with a working AI voicebot that answers real phone calls.
No slides-and-talk session. You’re building it yourself.
The Workshop: Build Your First AI Voicebot in 75 Minutes — From LLM to Live Phone Calls
When: February 13, 2026 · 4:15 PM – 5:30 PM
Where: VYAS - G - Room #VY003
Format: Hands-on workshop · First come, first serve · ~50 seats
Level: Intermediate — basic Python knowledge is all you need
AI voicebots are showing up everywhere in customer support, appointment scheduling, and order confirmations. The LLM side is getting easier by the month. But the part most developers struggle with? Connecting that bot to an actual phone number so real people can call it.
That’s exactly what we’re building in 75 minutes.
What You’ll Build
By the time you leave the room, you’ll have:
-
A conversational AI voicebot powered by your choice of LLM — GPT-4.1 mini or Gemini 2.5 Flash
-
Natural voice interaction with speech recognition and text-to-speech synthesis
-
Smart conversation handling with context memory and intent recognition
-
Live phone integration — call your bot from your own phone and talk to it
-
Deployable code ready for production use cases
No toy demos. The code you write in the session is production-ready.
The Agenda
Part 1: Building Your AI Voicebot (30 min)
We start from scratch. You’ll set up your LLM backend, design conversation flows and system prompts, add speech-to-text and text-to-speech, and test your voicebot locally. By minute 30, your bot can hold a conversation.
Part 2: Making It Real — Phone Integration (30 min)
This is where it gets interesting. You’ll learn how phone calls connect to your code through webhooks and APIs, connect your voicebot to real telephony infrastructure, handle inbound calls with real-time voice processing, and manage call flows — greetings, transfers, fallbacks. Then the moment: you call your voicebot from your phone.
Part 3: Production Tips & Q&A (15 min)
Error handling, graceful degradation, scaling for real-world traffic, and practical use cases. Plus open Q&A with the engineering team that builds this infrastructure at scale.
Who’s Running It
Narayanababu Laveti D V — Principal Architect at Exotel with deep expertise in building scalable communication systems. Currently leading voice AI technology development, working directly with the engineering team to make AI-powered voice bots smarter, more reliable, and capable of handling natural, real-time conversations over phone calls. His background in designing high-scale platforms for Exotel’s CPaaS and Enterprise Contact Centre means the architecture patterns you’ll learn are battle-tested at scale.
Shivaa Tripathi - Developer Relations at Exotel, leading the Exotel Developer Network. Focused on making voice AI accessible to India’s developer community.
You’re learning from the engineers who actually build this.
What to Bring
-
Laptop with Python 3.12+ installed
-
Code editor — VS Code recommended
-
Your mobile phone for live testing
-
Curiosity — no prior AI or telephony experience needed
Everything else — API keys, phone numbers, telephony infrastructure, sandbox access — is provided. No sign-ups or accounts required beforehand.
Surprise Goodies
We’re bringing some surprise goodies for workshop participants. First-come, first-served. Show up early.
After the Workshop
Every participant walks away with complete source code and continued sandbox access to keep experimenting. But if you want to go deeper and connect with other developers building voice AI in India, join the Exotel Developer Network at community.exotel.com.
You’ll find step-by-step guides, documentation, and a community of developers working on exactly these problems - sub-800ms latency on Indian telecom, Hindi and regional language support, and telephony integration that just works.
