The Big Question
What happens when your sales team doesn't have to dial a single number? When an AI voice agent handles thousands of conversations simultaneously, qualifies leads, and books meetings all while your reps focus on closing deals? And what if this entire system could be set up in under 4 minutes?
LeadGen+ answers these questions. It's an AI outbound calling CRM that automates the entire lead generation process—from prospecting and dialing to conversation and disposition. Built for Indian SMBs, LeadGen+ leverages cutting-edge AI voice technology to make outbound sales scalable, cost-effective, and relentless.
The Problem: Why Outbound Sales Is Broken for SMBs
For years, Indian SMBs have struggled with outbound sales. The challenges are universal:
-
Manpower constraints: Hiring and training telecallers is expensive and time-consuming
-
Low conversion rates: Manual dialing is inefficient, with most calls going unanswered or unqualified
-
Scale limitations: A human can only make so many calls per day, limiting lead generation capacity
-
Inconsistent quality: Performance varies widely based on agent skill, energy, and motivation
-
High churn: Sales roles have high attrition, leading to constant retraining costs
The result is a broken model where SMBs either overinvest in sales teams or underinvest in lead generation. LeadGen+ solves this by replacing manual outbound sales with AI-driven automation.
The Solution: LeadGen+ Architecture
LeadGen+ is built on a modern, scalable technology stack designed for high-volume outbound calling. At its core is a Django backend that orchestrates the entire lead generation workflow from storing leads and organizing campaigns to placing calls and streaming real-time data to the dashboard.
The Technology Stack
| Layer | Technology | Role |
|---|---|---|
| Web Framework | Django 5.2 + Django REST Framework | REST API, ORM, admin interface |
| Async Server | Daphne (ASGI) via Django Channels | Serves HTTP and WebSockets simultaneously |
| WebSockets | Django Channels 4 | Live dashboard feed and Exotel audio streaming |
| Channel Layer | Redis / In-Memory | Real-time event broadcasting |
| Background Jobs | Celery 5 + RabbitMQ + Redis | Campaign auto-dialing and retries |
| Database | PostgreSQL (Neon) | Primary data store |
| Telephony | Exotel v1 API + Voicebot WebSocket | Places calls and streams audio |
| AI Voice | OpenAI Realtime API (speech-to-speech) | The AI agent that talks on the call |
| AI Text | OpenAI Chat Completions (GPT-4o) | Disposition classification and intelligence |
| Deployment | Docker Compose (Postgres, Redis, RabbitMQ, Nginx, Certbot) | Full production stack |
This stack enables LeadGen+ to handle high-volume outbound calling with real-time audio streaming, live transcript delivery, and AI-powered conversation management all while maintaining enterprise-grade reliability and security.
The Life of an AI Call
The LeadGen+ architecture orchestrates a complex flow that happens in milliseconds:
-
User Action: A user clicks "Manual Dial" or a campaign worker picks the next lead. The system calls Exotel's API to place the call.
-
Exotel Connects: Exotel rings the lead from an ExoPhone (virtual number). When the lead answers, the call enters the Exotel dashboard flow, where a Voicebot applet opens a WebSocket to LeadGen+.
-
AI Agent Joins: The backend identifies which call it is, marks it "in_progress," and spins up a RealtimeBridge to OpenAI's Realtime API. The AI agent is configured with the campaign's system prompt and greets the lead by name.
-
Live Conversation: Audio flows seamlessly between Exotel and OpenAI PCM16 audio from the call is converted to µ-law and sent to OpenAI, while OpenAI's responses are streamed back to Exotel. The AI handles the full conversation, from pitch to objection handling.
-
Real-Time Transcripts: OpenAI emits text transcripts of both sides of the conversation. Each transcript is saved as a row in the database and broadcast via WebSocket to the live dashboard.
-
Call Completion: When the call ends, Exotel sends a status webhook. The system computes the duration, runs GPT-4o to classify the disposition (interested, callback, not_interested, no_answer, voicemail), and broadcasts the final status.
This entire flow happens in real-time, enabling sales teams to monitor live conversations as they happen.
