The Challenge

Just Dial's tele-marketing operation employs 8,000+ human agents handling massive call volumes. Scaling further with human agents alone is costly, and coverage gaps during off-hours lead to missed opportunities. The goal was to build AI voice agents that could autonomously handle routine calls, sharing the workload and providing 24/7 availability.

Key Features

๐ŸŽค

Real-Time Speech Processing

Low-latency speech-to-text and text-to-speech pipeline enabling natural, real-time voice conversations with customers.

๐Ÿง 

RAG-Powered Responses

Retrieval-augmented generation over product catalogs, pricing, and business information for accurate, context-aware answers.

๐Ÿ”„

Intelligent Call Routing

AI decides when to handle a call autonomously vs. when to transfer to a human agent, ensuring complex queries get human attention.

๐Ÿ“ž

Inbound & Outbound

Handles both incoming customer calls and proactive outbound campaigns with configurable scripts and conversation flows.

Technical Approach

01

Voice Pipeline

WebSocket-based real-time audio streaming with STT/TTS integration, keeping latency under acceptable thresholds for natural conversation flow.

02

Conversation Engine

LLM-powered conversation management with RAG context injection, handling multi-turn dialogues, objection handling, and call summarization.

03

Scale & Reliability

Concurrent call handling with automatic failover, call recording, and post-call analytics for continuous improvement.

Outcomes

  • Shared workload โ€” AI agents handle routine calls, freeing human agents for complex conversations
  • 24/7 availability โ€” no coverage gaps during off-hours or peak times
  • Consistent quality โ€” every call follows best practices and compliance standards
  • Scalable capacity โ€” AI agent pool scales elastically with call volume
