The Client

Based in Canada, this international fertilizer producer has over 1,500 retail locations with more than 23,500 employees worldwide.

Problem Definition

This organization was struggling with the work disruption of unwanted spam and telemarketing calls to its executives and staff, as well as toll costs related to dropped calls to their 800 lines.

The Story

This company was looking for a solution that could solve their problem of unwanted nuisance and scam calls ringing through to executives and staff. Their solutions architect team members attended the annual Cisco Live event in 2022 where they met with, and learned about, Mutare and the Mutare Voice Traffic Filter. They agreed to a Proof of Concept to test out the application on their Cisco voice platform, where they recorded an immediate reduction in wasteful, unneeded, and unwanted calls ringing through. This translated not only to a better work environment for employees, but also a positive ROI in reclaimed productivity and toll costs. The availability of the Voice CAPTCHA feature to guard against false positive call blocking was seen as a a valuable safeguard. Despite some ensuing organizational changes, the Mutare value proposition remained compelling and the organization agreed to the purchase and implementation of the Mutare Voice Traffic Filter, hosted in the Mutare cloud, for its headquarters staff. Their ultimate goal is to expand VTF protection into worldwide operations.
