A major oil company operating 307 retail locations nationwide eliminated rising POTS expenses and modernized its voice infrastructure with Mako Voice. By replacing outdated copper lines and consolidating multiple carriers into one cloud-hosted solution, the company cut costs by over $643,000 annually.

Mako’s comprehensive site surveys uncovered 606 unused phone lines that were still being billed, unlocking significant additional savings. With centralized management, advanced features like voicemail-to-email, and 24×7 white-glove support, the company didn’t just reduce spend — it improved functionality, security, and service across every location.

The result? Lower monthly costs, fewer vendors, stronger compliance, and a modern voice platform built for multi-site retail at scale.
