Unified Communications as a Service

While it might be a mouthful to say, a unified communications as a service (UCaaS) platform is designed to simplify your ability to deliver such features as enterprise telephony, real-time instant messaging, and video and audio conferencing. As with most modern technology today, this is all delivered via the cloud for greater convenience and security.

Market intelligence company Gartner predicts that spending on unified communications providers will rise at 4.1% CAGR to reach $50.8 billion in 2025, while cloud-based options continue to steal share from on-premise solutions. Here is a UCaaS provider comparison list of some of the top options available today. 

As businesses increasingly adopt Unified Communications as a Service (UCaaS) platforms, the choice of tools becomes even tougher. To understand this better, you can explore our comparative analysis of Skype vs. Zoom, as well as our recommendations for the best helpdesk software.
