What is Unified Communications as a Service (UCaaS) Software?
Unified Communications as a Service (UCaaS) is a cloud-delivered platform that unifies multiple enterprise communication and collaboration tools—such as voice, video conferencing, messaging, presence, and file sharing—into a single, integrated service. UCaaS replaces or extends traditional on-premises communication systems by providing scalable, subscription-based access to communication tools managed by a third-party provider. Modern UCaaS solutions incorporate AI-driven features (like transcription and meeting summaries), integrate with productivity and business applications, and enable seamless collaboration across devices to support hybrid and remote work environments. The category is also increasingly converging with adjacent markets like CPaaS and CCaaS.
