Real-Life Use Case

Eliminate Unwanted Voice Traffic


This is a real-life Use Case of a Mutare Customer and provides a high-level summary of the scenario and business problems resolved with the Mutare Voice Traffic Filter solution.




The Client

Arizona-based international mining company and world’s largest publicly-traded copper producer with 10,000+ employees and revenue of $22.9B.

Problem Definition

IT administrators were aware that spam, scam, robocalls and spam storms were infiltrating the organization’s voice network and disrupting employees, but there was no way of knowing the extent of the problem or how to fix it. When the CIO himself became the target of a nefarious scammer using a spoofed number, it was clear that finding an effective voice traffic filtering solution was now an imperative, not only to reduce workflow disruptions, but also for employee security.

The Story

At the onset of this organization’s search for a reputable call filtering solution provider, they received multiple recommendations to check out Mutare’s Voice Traffic Filter offering. They met with Mutare representatives and agreed to submit 30 days of CDR call records for Mutare’s free Voice Traffic Analysis. A run of that data through the filter’s proprietary dynamic database layer revealed that more than 18% of the organization’s voice calls – or approximately 300 daily – were clearly unwanted. The Mutare analysis also detected nefarious call activity within that unwanted voice traffic. The ability to further screen suspicious calls through the Voice CAPTCHA to separate legitimate calls from auto-callers was an important distinction for the Mutare solution. This organization also recognized the productivity-enhancing utility of the application’s flexible custom rules creation and management capabilities when used to direct calls from specific sources or types to specialized teams or a voicemail system. Once Mutare’s full five layers of filtering technology was implemented, the organization experienced the full benefits, including the application’s ability to detect call surges indicating a spam storm, and then redirect those calls through Voice CAPTCHA to separate out legitimate callers from bots. This enterprise now reports significant relief from the ongoing disruption of spam calls as well as a heightened sense of security for the enterprise and its people.
