Application specialist RingCentral is the top UCaaS provider in terms of revenue, supported endpoints and number of UCaaS employees, according to Gartner. The Belmont, Calif.-based company uses an internally developed, multitenant offering, RingCentral Office, with a rich UC suite. RingCentral recently added a workstream collaboration capability to its UCaaS suite through its 2015 acquisition of Glip, a cloud messaging and collaboration company.
The company told CRN earlier this year it was making its biggest charge ever into the enterprise market this year by forming a new partnership with Avant Communications and Google. RingCentral is the No. 1 leader for vision on the Magic Quadrant and ranks among the middle of the pack for execution.
