The Client

Among the top ten largest brokerage and investment banking firms in the country, with nearly 9,000 employees and $5.16 billion in revenue.

Problem Definition

This organization places a high priority on customer support accessibility through voice calls but was concerned about the increasing impact unwanted nuisance and nefarious callers were having on its contact center cost of operations and organizational security.

The Story

This organization reached out to Mutare in 2021 requesting a Voice Traffic Analysis to gain better insight into the types of calls entering their Five9 cloud contact center operations. The assessment revealed that, at the time, roughly 1,000 calls per day were deemed spam. What’s more, according to Mutare studies, nearly 45% of all unwanted calls are nefarious in nature and likely include those from cybercriminal vishers attempting to socially engineer agents and breach customer accounts. In the spring of 2023, Mutare became a Five9 developer partner, extending its enterprise Voice Traffic Filter solution to the Five9 cloud contact center community. Having reengaged with this organization, Mutare was able to demonstrate the ease of implementation and full capabilities of its Voice Traffic Filter with simple API integration. Through a quick 30-day Proof of Concept trial, Mutare effectively demonstrated how VTF removes the vast majority of unwanted calls before they reach other downstream caller authentication processes or the agent desktop. At the same time, Mutare’s Voice CAPTCHA feature combined with its flexible rules creation capabilities provided much-needed assurance that no live caller would be inadvertently blocked due to a false positive flagging. VTF call filtering at the front end of the call flow not only reduces the negative impact of unwanted calls on network efficiency and agent security but, in the process, reinforces the efficiency of other standard caller authentication applications and processes deployed by the client.
