Metrigy’s third-annual UCaaS MetriRank study introduces its new Leadership Landscape, plotting the market position of the ranked providers.

June 11, 2026 – Research and advisory firm Metrigy released its UCaaS MetriRank 2026 report, identifying Cisco as No. 1 among Top 10 providers leading the market today and best positioned for long-term success. Providers are evaluated on financials, market share, product, and customer insights to assess long-term market sustainability and success.

Market share is the gating factor for inclusion in the UCaaS MetriRank, with a handful of large providers in a broad marketplace comprised of lots of options with Microsoft, Cisco, Zoom and RingCentral leading. According to Metrigy’s workplace collaboration market share and forecast report, the global market for UCaaS was $23.0 billion in 2025, up 6% year-over-year. Metrigy forecasts the worldwide market to grow at a 4% CAGR from 2025 to 2030, reaching $28.0 billion by 2030. This continuous growth highlights a mature enterprise environment, where Metrigy’s benchmark research shows that 58.6% of businesses worldwide now deploy UCaaS as their sole phone and workplace collaboration platform. 

In this report, we introduce the new Leadership Landscape. Based on the evaluation criteria listed above, scores are measured and plotted into three categories: foundation, customer, and market. The result is Cisco, Zoom, Microsoft, RingCentral and Verizon in the Leaders segment. Cisco and Zoom have strong and balanced foundation and customer scores. Microsoft has the strongest foundational score. RingCentral and Verizon have the strongest customer scores.

“The five leaders within the UCaaS MetriRank Landscape have had long-term success in the market through a focus on product development, go-to-market momentum, and customer success. Cisco has earned the overall top ranking with continue growth migrating businesses to the cloud,” said Diane Myers, senior research director and principal analyst responsible for Metrigy’s MetriRank reports as well as market share and forecasting. 

Metrigy 2026 UCaaS MetriRank Highlights

Following the Leaders listed above: 

• Landscape Challengers include Vonage, 8×8, Gamma, and GoTo. These providers are doing well and just miss the leadership segment, making them a competitive threat. Gamma is a standout within the group of challengers as the provider with the strongest market score.
• Landscape Performers tend to be smaller providers but deserve attention of having a high enough market share to be including in the MetriRank. They are not to be counted out, having strength in specific areas that allow them to be nimble and focused. Nextiva is the sole provider in the performer segment.

Additionally, UCaaS providers that did not make the 2026 ranking but are on Metrigy’s watchlist due to strong performance in specific verticals include: Comcast, Dialpad, Fusion Connect, Google, Intermedia, Sangoma, Wildix, and Windstream. 

Metrigy defines UCaaS as a cloud-based suite of integrated communications and collaboration applications that, at a minimum, provides public switched telephone network (PSTN) connectivity. Offers may be sold as telephone-only services or bundled with other enterprise capabilities, including video meetings and team messaging.
