    Our story begins with ArcelorMittal Tubular, an offshoot of the larger ArcelorMittal. This division of the company manufactures steel tubes and once relied on an Avaya system to stay connected. In 2011, they found a partner that could effectively manage these legacy voice systems, keeping them running like day 1. That partner was Continuant.  

    Twelve years later, a new challenge arose. ArcelorMittal looked to begin its migration to Microsoft Teams. ArcelorMittal once again partnered with Continuant to deploy a Teams Calling solution powered by NuWave communications.  

    The initial migration took place in Mexico with 1,500 users. Currently, Continuant and ArcelorMittal are in talks to potentially migrate users across the US and Canada. 

    No matter how tough the migration may seem, this steel producer knows it can rely on solutions and services from NuWave and Continuant.  

    Based in the tiny country of Luxembourg, ArcelorMittal is the world’s second-largest steel manufacturer. Its goal is to ensure steel continues to be the world’s most used and versatile material. It ranks #197 on the Fortune 500 and employs more than 158,000 people across the globe.  

    The Challenge: 

    • Avaya systems at ArcelorMittal Tubular needing maintenance 
    • Migration for 1,500 users in Mexico to Microsoft Teams 

    The Solution: 

    • 10+ years of consistent Avaya maintenance 
    • Continuant Connect Teams Calling solution 
    • Full migration services for Mexico locations and all 1,500 users
