Prospera Credit Union achieves 90%+ answer rate and handles 10x call surge with Voice AI

Prospera Credit Union faced a major system upgrade (core conversion) that peer institutions warned would cause call volumes to surge three to five times. With a lean call center team, adding more staff was not sustainable. Their existing IVR-based phone banking was insufficient to absorb the expected demand spike while maintaining service quality.

Prospera implemented interface.ai's Voice AI (Intelligent Virtual Assistant) integrated with their core system Symitar and VoIP platform RingCentral. The solution automated routine member interactions, passed detailed member context and interaction history to live agents for warm handoffs, and used built-in analytics to continuously identify common questions and expand self-service coverage.

On go-live day, call volume surged tenfold from 220 to 2,500 calls — 43% were fully resolved without live agent transfer. In the first five days, Voice AI handled a substantial volume of member conversations, equivalent to 3.5 full-time employees. Over time, monthly call volume grew from 5,700 to over 8,000, while answer rate improved from the low 60s to over 90% and average wait times dropped to just over one minute.

• Align AI projects to clear business pillars (member experience, staff efficiency, risk management) before starting implementation to ensure strategic fit.
• A major system migration or operational stress event can serve as a forcing function to accelerate AI adoption and demonstrate ROI quickly.
• Deep integrations with core banking systems (Symitar) and telephony (RingCentral) are critical — passing member context to agents eliminates repetitive questioning and improves resolution speed.
