“Microsoft, Cisco, and Zoom remain the leading workplace collaboration providers, expanding their market shares in calendar year 2024,” says Diane Myers, Metrigy senior research director. “The combined market of on-premises PBX platforms and UCaaS services grew 5% in CY24 but growth rates will taper off over the next five years as more businesses migrate to the cloud, and the market hits a steady subscription revenue flow.”
