Eliminate Unwanted Voice Traffic

Oil & Gas

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.



Oil & Gas

The Client

World’s largest independent oil and gas E&P company with a worldwide employee force of 10,000 and a market capitalization of $141.6B.

Problem Definition

While this customer was already utilizing a standard call filtering solution, they had become increasingly concerned about the excessive amount of unwanted spam, scam and robocalls still ringing into their U.S.-based headquarters, disrupting employee workflow, overwhelming helpdesk with call-blocking requests, and creating security concerns.

The Story

This enterprise was increasingly concerned about the amount of spam traversing their voice network despite the fact that they already had a filtering solution in place. When leadership decided it was time to explore alternative solutions, they were introduced to Mutare. Mutare provided a free, basic Voice Traffic Assessment running three months of the prospect’s CDR data through the Mutare Voice Traffic Filter’s dynamic database of unwanted callers. This filtering layer alone flagged nearly 17% of those calls as unwanted. The prospect then took the next step of conducting a Proof-of-Concept trial using the Mutare solution’s full five filtering layers while keeping the existing solution in place. The result: Mutare captured 30% more unwanted and potentially nefarious calls that were passing through, undetected, by the existing filtering system. From the user dashboard, administrators could clearly see filtering activity by layer, including custom rules activity and spike events triggering Threat Radar alerts. The Voice CAPTCHA feature was a key differentiator as it provided reassurance against possible false-positive flagging of a legitimate caller. Systems engineers were additionally impressed by the level of personal control they are afforded through the application’s web-based administrative interface without need for managed services, while IT helpdesk staff welcomed the VTF feature supporting user-created personal call blocking. These results, including an estimated ROI of 226%, made the purchase decision in July of 2023 an easy one. Today, this customer continues to benefit from Mutare’s robust voice traffic filtering capabilities. They report that approximately 25% of their incoming calls are consistently detected as unwanted and diverted before those callers reach, distract, or potentially perpetrate fraud on their intended recipients.
