• Client: A Philippine pharmaceutical company

The Problem

A Philippine pharmaceutical company was outsourcing its customer service hotline to a traditional call center at significant monthly cost. The call center handled product inquiries, order processing, and complaint management, but operated on fixed schedules with limited capacity for scaling during peak periods. The company needed a solution that could provide 24/7 availability, handle conversations in multiple Filipino languages (English, Taglish, and Cebuano), and significantly reduce operational costs.

More importantly, the pharmaceutical industry has specific requirements around product information accuracy, order verification, and complaint documentation that generic AI chatbots aren't designed to handle. The solution needed to be both conversationally intelligent and operationally reliable.

Our Solution

IOL designed a comprehensive AI voice agent system combining specialized voice AI processing, large language model intelligence for conversational understanding, and Philippine telephony infrastructure. The system doesn't just answer calls — it actively looks up products, processes orders, logs complaints, and sends confirmation messages, all through natural conversation.

The architecture features real-time tool-calling, where the AI agent can access the product catalog, create orders, check inventory, and trigger SMS/email confirmations during a live call. For the Philippine market, this required integration with local telephony providers and SMS services, plus careful handling of multilingual conversations where callers may switch between English, Taglish, and Cebuano mid-sentence.

Key Takeaways

1. AI voice agents are now viable replacements for traditional call centers in the Philippine market, with multilingual support that matches the country's linguistic diversity.

3. The cost reduction potential makes AI voice technology accessible to SMEs that could never afford traditional call center outsourcing.
