Case Study Overview

The Challenge: PolyAI's enterprise clients operated contact centers handling millions of inbound calls annually, with over 60% of those calls involving routine inquiries—booking confirmations, account status, order tracking, FAQs—that required no complex human judgment. Long hold times averaging 8 minutes, agent burnout from repetitive interactions, and inconsistent service quality across agent shifts were driving measurable customer churn.

The Solution: AGIX built a production-grade voice AI platform with natural language understanding capable of handling complex, multi-turn conversations across multiple languages and regional accent variations. The system integrates with CRM, booking, and ticketing systems to resolve inquiries end-to-end—accessing live customer data to provide personalized responses—and escalates to human agents with full conversation context only when the inquiry genuinely requires human judgment.

The Impact: 87% of inbound calls now resolve fully through voice AI without any human intervention. Average hold times dropped from 8 minutes to under 30 seconds, the single largest driver of improved customer satisfaction. CSAT scores improved 22% as the near-instant response experience outweighed initial caller reluctance. Human agents, freed from repetitive calls, handled a higher proportion of complex cases where empathy and judgment create real value.

The Challenge

Traditional Call Centers Couldn't Scale

Enterprise contact centers faced a perfect storm: customers waited in endless queues, human agents cost $12+ per call, and CSAT scores tanked as hold times grew. The old IVR systems—press 1 for this, press 2 for that—frustrated callers and created more escalations than they resolved. Companies needed voice AI that could actually resolve issues, not just route calls to the next queue.

"Customers tell us they didn't realize they were talking to AI until we mentioned it. The latency is so low and the responses so natural that it feels like a real conversation. That's the bar for enterprise voice AI."
