More enterprises are deploying AI call center solutions than ever, but the ones actually delivering results aren't pursuing full automation. They're running hybrid models. In a recent interview, AVOXI CEO Barbara Dondiego noted that most organizations are only using AI in 5–10% of real-world deployments. The gap between ambition and execution is telling.
The Full Automation Trap: When Numbers Meet Reality
In a 2022 report, Gartner projected that conversational AI would reduce contact center agent labor costs by $80 billion by 2026. The prediction assumed one in ten agent interactions would be automated, up from just 1.6% at the time. With approximately 17 million contact center agents worldwide, the stakes were enormous.
But reality has been more nuanced. Many organizations that pursued full automation have paid the price in customer churn and declining CSAT scores. The issue isn't the technology itself—it's the scope of application.
Why the Hybrid Model Wins Structurally
Nearly half of successful voice AI deployments use a hybrid human+AI model. The logic is straightforward: let AI handle what AI does best, and let humans handle what humans do best.
- Simple inquiries (reservation checks, balance lookups, FAQs): AI responds instantly, zero wait time
- Complex claims, emotional situations, multi-step decisions: skilled agents handle directly
- Real-time AI assist: customer history and recommended scripts displayed on-screen during live calls
In this structure, AI absorbs 60–70% of call volume while agents focus on high-value conversations. Customer service teams using AI agents have reported an average 14% productivity increase, and personalized AI-assisted service has driven customer satisfaction gains of up to 27% (CX Today, 2025).
Airline Case Study: Targeting 80% Automation While Keeping Humans
Aviation is among the most aggressive industries in AI automation. Gartner projects that by 2029, agentic AI will autonomously resolve 80% of common customer service issues without human intervention. But the critical insight is in the remaining 20%.
Korean Air chose a hybrid path: equipping agents with AI-powered speed, security, and real-time assistance rather than replacing them with bots. In high-stress travel scenarios, what customers actually want is empathy and problem resolution.
Simple rebookings and mileage inquiries go to AI, while post-cancellation rebooking and compensation negotiations stay with humans. This is why airlines pursue 80% automation while retaining their agent workforce.
The Evolving Agent Role: From Admin-Heavy to Outcome-Based
In hybrid models, the agent role transforms fundamentally. Previously, administrative tasks—logging call records, searching customer profiles—consumed a significant portion of call time. With AI automating these functions, agents now focus on outcome metrics: CSAT, revenue contribution, and complex problem resolution.
This shift isn't just about operational efficiency. It directly impacts agent job satisfaction and retention. Moving from repetitive, low-value calls to meaningful customer interactions changes the nature of the work itself.
Use Cases That Actually Work
According to AVOXI's analysis, the call center use cases where AI delivers measurable results are well-defined.
- Simple Call Containment: calls resolved without agent transfer—FAQs, account balances, shipment tracking.
- Reservations and scheduling: restaurants, clinics, hotels—the highest success rates for voice AI agents.
- Outbound confirmation calls: appointment reminders, delivery confirmations, surveys—structured conversations with predictable flows.
Conversely, insurance claim negotiations, multi-step technical troubleshooting, and emotionally sensitive medical consultations see sharp drops in AI-only success rates.
BringTalk's Perspective: Why Hybrid Is the Answer
When BringTalk advises enterprise clients on voice AI, the first question isn't 'which calls should we automate?' It's 'which calls do your customers expect a human for?' The scope of automation should be defined by customer experience standards, not technology limits.
