The Client

Specialty chemical, fiber, and resin research and production organization with operations in 31 countries, an employee force of more than 11,000, and net worth topping $4B.

Problem Definition

A growing abundance of distracting spam and scam calls were hitting desk phones of plant supervisors, interrupting normal administrative duties, and creating significant safety concerns.

The Story

Supervision of plant operations for this enterprise is provided 24/7 through trained personnel who oversee general operations from control centers. They are tasked not only with assuring operational efficiency but also plant safety and security. However, in recent years, they have experienced a growing onslaught of spam and scam call activity ringing into their desk phones – according to the company’s network administrator, as many as 40 unwanted calls per day, some perceived as potentially nefarious, could be hitting a single line. These calls were not only disrupting normal administrative activities, but they were also taking attention away from control systems monitoring – a critical concern when dealing with volatile chemicals and the disastrous impact should a fire or spill go unnoticed. Plant leadership agreed to a Mutare Voice Traffic Assessment which revealed an unusually high percentage of unwanted calls ringing into supervisors’ desk phones. A Proof of Concept implementation of the entire Voice Traffic Filter five layers of protection confirmed that more than 14% of incoming calls were, indeed, unwanted and included malicious spam storms and other potentially nefarious intrusions. The value of Mutare’s Voice Traffic Filter in terms of plant safety and employee security was easily recognized and the purchase finalized.
