CallTower: 2025 Frost Radar™ Leader in UCaaS Innovation and Growth

In the rapidly changing world of modern business, having the right Unified Communications as a Service (UCaaS) and cloud-calling services can make all the difference for your organization, and choosing the right service providers is a necessity to stay ahead. Your business needs a service provider that is both innovative enough to adapt to market trends and capable of sustainable, long-term growth. That’s where CallTower comes in. 

In Frost & Sullivan’s 2025 Frost Radar™, CallTower ranked the highest on both the Growth Index and the Innovation Index, marking CallTower as a leader in North American UCaaS and Cloud-Connected Calling Service Providers. This position is a testament to our years of dedication and smart investments, and it highlights our ability to anticipate change and adapt rapidly. 

Here, we will explore what the Frost Radar is, what CallTower’s position in the Frost Radar means, and why that position matters.

Why Training Makes the Difference

The Frost Radar™ is a visual benchmarking tool by Frost & Sullivan that evaluates companies' performance and growth potential in specific industries. It helps businesses, investors, and stakeholders identify key players, assess competitive positioning, and uncover growth opportunities. 

The Frost Radar™ features two key axes. First is the Innovation Index, which measures a company’s innovation, adaptability, and alignment with market trends, and second is the Growth Index, which evaluates sustainable growth through market share, revenue, and efficiency. Together, these axes provide a comprehensive view of a company’s market position, enabling informed decision-making and fostering strategic growth in dynamic industries. 

What CallTower's Position in the Frost Radar Means 

CallTower’s leadership position in the Frost Radar underscores our exceptional ability to grow and innovate in the UCaaS market. Our growth is fueled by offering tailored solutions across leading platforms like Microsoft Teams, Cisco Webex, and Zoom. Instead of forcing a one-size-fits-all product, we meet you where you are, integrating powerful voice capabilities into the tools your team already uses. Strategic acquisitions, like OneStream Networks and Inoria, have expanded our global reach and deepened our expertise in contact center AI and analytics. 

On the innovation side, we differentiate ourselves through proprietary platforms like CallTower Connect, which simplifies service management, and integrations with contact center solutions like Genesys Contact Center, Five9 Contact Center, and Ascend Teams Contact Center. Innovations like Entra Sync for Microsoft Teams lifecycle management and Teams Mobile and Webex Go for secure mobile communications demonstrate our focus on creating flexible and secure solutions for diverse business needs. This dual focus on robust growth and meaningful innovation is what placed us at the forefront of the UCaaS industry.
