Top 20 UCaaS Vendors and Solutions

Transitioning your business communications environment from a traditional on-premise phone system to a cloud-based unified communications solution is no longer a question of if, but instead when?

You are probably aware that UCaaS is one of the fastest-growing communications solutions in the industry and in very high demand by businesses of different shapes and sizes – small to mid-sized companies, large businesses, and global enterprises.

It’s also a very crowded space from both a vendor and solution perspective. It’s very difficult to evaluate which UCaaS vendor and solutions are right for your business. You shouldn’t blindly select a UCaaS vendor without doing a lot of due diligence like demos and presentations.

Gartner Report

The Gartner Magic Quadrant is one of the most well-respected reports in the communication and collaboration space. Every year, companies fight for a chance to be listed in one of the significant segments of the report, from leaders to challengers, niche players, and visionaries.

This year’s Magic Quadrant for Unified Communications as a Service was just as exciting as ever. In the latest report, Gartner even suggested that 40% of all telephony purchases by 2023 will be made through a cloud-based suite. As a result, various aspects of the MQ changed to focus on the new nature of the marketplace. For instance, up until recently, Cisco and Microsoft weren’t featured as front-runners of the UC market. However, this year, both companies have gained ground.
