Case Study: CallRail achieves reliable, cost-effective, hyper-intelligent call tracking with Plivo Voice API

CallRail and Plivo’s Voice API Turn Call Tracking Into Hyper-Intelligent Marketing

CallRail provides call-tracking and analytics that show which marketing channels drive phone leads, helping businesses measure offline conversions without new infrastructure or long-term contracts. To deliver clear, recorded calls and real-time number swapping at scale—while keeping prices competitive—CallRail needed a reliable, high-quality voice platform that could integrate with Google Analytics, Salesforce and other marketing systems.

By powering its service with Plivo’s Voice API, CallRail added dynamic number replacement, reliable call forwarding, recording and transcription, and broad carrier coverage without raising costs. The result: rapid customer growth (25,000+ customers), coverage of 300+ U.S. area codes, improved call quality and uptime, measurable cost savings, and an easier path to international expansion while keeping its call analytics feature-rich and affordable.
