What exactly is UCaaS and how does it differ from a Cloud PBX?
A Cloud PBX replaces your on-premise phone system with a hosted equivalent — calls, extensions, voicemail. UCaaS goes further by unifying voice, video conferencing, team messaging and file collaboration into a single platform with one login, one app and one admin console. The key difference is that UCaaS treats all those channels as native — not separate products bolted together.
