How to Automate Call Centers
With the rise of large language models (LLMs), businesses now have access to AI-driven customer service applications that promise both efficiency and cost savings. This shift has given rise to two models:
- AI-first call centers, where AI enhances human agents to improve speed and personalization.
- Agentless call centers (ACC), where AI automates as many interactions as possible, reducing human involvement in call handling significantly.
1. The AI-First Call Center: A Smart Upgrade for Phone Support
An AI-first voice call center doesn’t replace human phone agents—it redefines their role. Instead of manually handling every call, agents work alongside AI to deliver faster, more intelligent, and context-aware phone support. Traditional call centers often operate in silos, forcing customers to repeat themselves across different calls. AI-first voice models aim to unify these interactions, enabling seamless continuity across phone conversations.
Example:
A customer starts with an automated voice system, then transitions to a human agent for a complex issue. It happens without having to repeat any details previously shared with the voice system.
While this improves continuity, execution is key:
- When AI misinterprets caller intent, can customers easily reach a human agent for help?
AI-first call centers don’t necessarily rely on a single AI system or platform—they integrate multiple models to enhance customer interactions, including:
- Sentiment analysis to detect customer emotions.
- Intent recognition to understand caller needs.
- Predictive analytics to anticipate and resolve issues before they escalate.
Yet, even with 90% sentiment accuracy, 10 out of 100 customers could still be misinterpreted, and this is pretty poor containment to a very high cost.
2. Agentless Call Centers: The Ultimate Efficiency for Phone Support
The agentless call center (ACC) takes AI-first to its extreme—minimizing or even eliminating human agents. AI-powered voice assistants and automated workflows manage nearly every call.
AI can handle 80–90% of customer interactions, reducing costs and ensuring 24/7 availability. However, challenges may remain if the system is built for an AI first scenario and not for full contact center automation.
The agentless model reduces reliance on human agents by automating call containment and intelligently routing calls. There are levels in this implementation:
- Level 1: AI agents route incoming calls to the appropriate human agents, reducing misrouted calls and increasing First Call Resolution (FCR).
- Level 2: AI agents automate 50% of Level 1 support tasks, further improving efficiency.
- Level 3: AI agents automate 100% of Level 1 tasks and up to 50% of Level 2 tasks.
