Q: What is UCaaS? Unified Communications as a Service

UCaaS, or Unified Communications as a Service, is a cloud-delivered, subscription-based platform that brings business voice calling, team messaging, video meetings, and related tools into a single service. Employees use one set of apps for internal and external communication, and IT manages it centrally.

What UCaaS includes

The exact bundle varies by vendor, but a UCaaS platform generally covers the ways people inside a company talk to each other and to customers.

Business phone service (a cloud PBX)
Team chat and presence, so colleagues can see who is available
Video and audio conferencing
SMS and fax
Voicemail, call recording, and analytics
Integrations with CRM, calendar, and productivity tools

How UCaaS is delivered

UCaaS is multitenant and subscription-based. The vendor operates the infrastructure, keeps software current, and charges per user per month. Users reach the service through desktop, web, and mobile apps or IP phones, so the same identity and number work from anywhere.

Who benefits from UCaaS

UCaaS suits organizations whose staff collaborate across offices, home, and mobile devices. It replaces a collection of separate phone, meeting, and messaging subscriptions with one platform and one admin console, which usually simplifies administration and user training.

UCaaS and contact centers

UCaaS is aimed at employee collaboration and general business calling. Teams that handle high volumes of customer interactions often add contact center capabilities such as queues, dialers, and agent reporting. The two are complementary, and many companies run both. For a full comparison, see UCaaS vs CCaaS.
