RingCentral was founded in 1999 by CEO Vlad Shmunis. The company is headquartered in Belmont, California with satellite offices in Denver, Colorado, Charlotte, North Carolina, Boulder, Colorado, and Boca Raton, Florida. International offices for Ring Central are located in Toronto, London, Paris, Singapore, Milan, Xiamen China, St Petersburg, Russia, and Odessa, Ukraine as well. RingCentral specializes in cloud-based communication services, marketed primarily to businesses. RingCentral Office provides cloud-based office related phone services. Other products include RingCentral Professional, RingCentral Fax, RingCentral meetings and webinars, and a workstream collaboration platform that includes messaging, task and event management, and document sharing features known as RingCentral Glip.

RingCentral Office plans start at $19.99 per month per user for their Essentials plan, $24.99 per month per user for the Standard plan, $34.99 per month per user for the Premium plan, and $49.99 per user per month for the Ultimate plan. The Standard, Premium, and Ultimate plans go down in price for businesses with more than 100 users and drop even further in the per-user price for businesses with more than 1,000 users. A 15-day trial is offered to new customers with some feature limitations on how much use each user will receive during the trial. Trial plans that are not cancelled within the 15-day period will automatically convert to a paid plan based on the selections made when signing up at the end of the trial period.

Plans can be paid monthly or annually for a discount, with plans automatically renewing at the end of the paid period. Plans may be cancelled at any time, though refunds may or may not be available if cancelled early. The information below will assist in cancelling a RingCentral plan.
