Frost Radar: European UCaaS and Cloud-Connected Calling Services, 2025

A Benchmarking System to Spark Companies to Action - Innovation That Fuels New Deal Flow and Growth Pipelines

The European UCaaS market is at an inflection point. Organizations are rethinking work styles, accelerating digital transformation, and redefining the role of communications in the modern enterprise. Hybrid work, mobility, and rising user expectations are reshaping demand. Employees now expect frictionless communication across devices, networks, and collaboration platforms. While market growth remains solid, it is beginning to normalize as adoption matures. With the first wave of cloud migrations largely complete, providers are pivoting toward driving deeper customer value through upselling, cross-selling, and lifecycle engagement. AI-powered capabilities, advanced collaboration tools, and integrated CCaaS/CPaaS offerings are becoming key differentiators.

This Frost Radar™ benchmarks leading wireline and mobile carriers, managed service providers, ISPs, VARs, systems integrators, and other resellers delivering hosted IP telephony, cloud PBX, and UCaaS solutions. Provider selection was based primarily on the size of their European UCaaS installed base, with exclusions where growth and innovation data were insufficient. Growth Index ratings reflect historical performance and future growth potential, using installed UCaaS seats and revenue models to assess market share and financial stability. Innovation Index ratings measure the depth and pace of capability development, aligned with major technology trends. Providers are evaluated across 10 Growth and Innovation criteria, positioning them on the Frost Radar™ and highlighting competitive strengths and strategic opportunities.
