The Challenge
The client experienced high phone drop rates and long queue hold times over 15 minutes during peak hours. Inbound call centers were over-capacity, leading to lost sales appointments and severe staff burnout.

Handled over 12,000 inbound phone calls monthly with 82% resolution rate
Zero missed sales leads with 24/7 automated call booking
Saved an estimated $180,000 annually in call center staffing costs
