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

California-based debt management company specializing in debt resolution, debt settlement, and customer service provided through a 150-agent cloud contact center with an A+ rating from the Better Business Bureau.

Problem Definition

This organization, which maintains customer financial data as a central part of its business operations, was being targeted by vishing attacks from threat agents attempting to breach those customer accounts. While recognizing the critical need for increased security around incoming calls, they were concerned that heavy-handed caller screening could negatively impact customer experience. They were, additionally, wary of applications using reputation databases alone for call screening and the possibility that legitimate calls from their debt consolidation agency partners might be flagged, and blocked, as suspected spam.

The Story

Using untraceable VoIP calling software to spoof their numbers and hide their identities, cybercriminals were calling into this organization’s customer support lines, posing as real customers in need of assistance with their accounts, and then attempting to trick agents into betraying protected account information. When this scheme actually led to a successful account breach, the organization’s security team recognized the critical and immediate need to protect agents and the customers they serve against fraudulent callers. Their Five9 CCaaS provider introduced them to Mutare reps, who provided a demonstration of how the Mutare Voice Traffic Filter solution adds enterprise-grade voice call analytic and filtering capabilities to the Five9 platform. Taking advantage of Mutare’s rapid API integration, the organization agreed to a free 30-day Proof of Concept hands-on trial of the Mutare solution’s full five filtering layers within their cloud call center environment. The impact of reduced calls from spammers and scammers was immediate. What’s more, using the application’s flexible custom rules builder, admins were able to create allow lists for numbers associated with their known debt consolidation partners, assuring that those calls would always ring through. After three weeks of trial, they were so convinced that they had found their solution that they agreed to roll straight from POC into a full purchase – just three months from demo to sale.
