Overview

VoIP & Unified Communications covers the cloud-based voice, messaging, video, and collaboration services that have replaced traditional business phone systems — unified communications as a service (UCaaS) and cloud contact centers (CCaaS). It is led by cloud-communications providers (Zoom, RingCentral, 8x8, Microsoft Teams Phone, Cisco Webex) delivering communications as software.

Demand is driven by the migration from on-premise PBX to cloud communications, hybrid work, and the integration of voice into collaboration platforms, with the line between UCaaS and collaboration software blurring (Microsoft Teams a powerful force). It is consolidating, facing competition from the productivity-suite giants embedding communications, with AI (transcription, agents, contact-center automation) the transformative new layer; it is a fast-evolving cloud-software category disrupting legacy telecom.
