How Mutare Integrates Nomorobo to Stop Unwanted Calls Before They Start

Robocalls and spam messages plague businesses daily — and for many organizations, these unwanted interruptions waste time, reduce productivity, and expose sensitive information.

Mutare, a voice security software company serving enterprise clients, knew there had to be a smarter way to block spam calls without disrupting legitimate communication.

That’s when they turned to Nomorobo.

Challenge

Mutare wanted a better way to filter and deny spam calls without risking critical business calls.

In industries like healthcare, automated calls play a vital role — for example, pharmacies or insurance carriers contacting patients. However, many of these legitimate calls were being incorrectly flagged as spam, creating confusion and missed communications.

With 20% of their clients in healthcare, Rich Quattrocchi, Vice President of Digital Transformation at Mutare, needed a precise solution — one that could distinguish between robocall scams and legitimate automated calls.

Before Nomorobo, Mutare’s filtering relied on static databases and manual blacklists. That meant their teams spent hours managing unwanted calls that still slipped through. As Rich explains:

“What might be spam to you or me on our mobile phones is not necessarily spam to an enterprise. We needed partners that could provide reputation information on calls coming into the organization.”

 

Solution

Nomorobo helped Mutare tailor spam protections to industry-specific needs.

Unlike generic spam blockers, Nomorobo’s API integrates directly into Mutare’s voice traffic filter layers — identifying suspicious numbers in real-time using one of the most comprehensive robocall databases in the world.

Mutare uses Nomorobo’s call reputation data to:

• Identify and block known spam and fraud sources

• Allow necessary automated calls from trusted senders (like pharmacies and hospitals)

• Flag high-risk robocalls for deeper analysis

“We’re able to use custom rules to enable calls that might otherwise get flagged as spam but are critical for enterprises. Even the calls we let through are only sent to the person that needs to receive the call,” Rich shared.

 

Results

Mutare successfully blocks or filters 10% of all unwanted calls while improving productivity and client satisfaction.

With Nomorobo integrated into its multilayered voice security system, Mutare’s clients block spam calls before the first ring — saving time, protecting data, and keeping employees focused.

The results speak for themselves.
