The Story

In their discovery process, the company’s leadership had narrowed down their choice for an enterprise spam blocking solution to two vendors, one being Mutare. They agreed to implement the Mutare Voice Traffic Filter for a five week Proof of Concept. During that time, administrators had full hands-on experience with the system interface and controls. Over the POC period, the filter processed 155,181 incoming calls and identified 18,162 of those calls, or 12%, as spam or robocalls. What’s more, Mutare research revealed that more than 8,000 of those calls likely carried nefarious intent. The Mutare solution was able to detect unusual call influx (spam storms) at the onset through pattern recognition and automatically direct traffic to its proprietary Voice CAPTCHA which preserved network performance while assuring that legitimate callers could still get through. In a side-by-side comparison of product features, performance, and team support, the Mutare solution, with a projected ROI of 525%, beat out the competition on multiple levels.
