RingCentral

RingCentral is the world's leading pure-play UCaaS platform company, headquartered in Belmont, California and publicly traded on the NYSE as RNG. With approximately 3,200 employees and data centers across the United States, Europe, and Asia-Pacific, RingCentral has spent more than two decades building what is arguably the most feature-complete, most integrated, and most broadly deployed cloud communications platform in the enterprise market.

RingEX Platform

RingCentral's flagship product, RingEX (formerly RingCentral MVP), unifies voice, video, team messaging, and AI across a single proprietary platform. The platform's 99.999% uptime SLA is achieved through multi-region redundant architecture across Ashburn, Chicago, Dallas, San Jose, Amsterdam, Singapore, and Sydney.

AI-Native Communications

RingCentral has embedded AI throughout RingEX — real-time transcription, meeting summaries, sentiment analysis, next-action suggestions, and RingSense AI for post-call intelligence. These capabilities are native to the platform rather than bolt-on add-ons, and represent RingCentral's most significant competitive investment in 2024–2025.

App Ecosystem

With 300+ pre-built integrations covering Salesforce, Microsoft 365, Google Workspace, ServiceNow, Zendesk, HubSpot, and dozens of healthcare, legal, and financial services applications, RingCentral's app ecosystem depth is unmatched in the UCaaS category. For organizations that want their communications platform to connect deeply with their existing software stack, this breadth matters operationally.

Government and Compliance

RingCentral holds FedRAMP Authorization for its government-tier offering, HIPAA BAA availability for healthcare, SOC 2 Type II, and ISO 27001. This compliance posture positions RingCentral as a credible enterprise choice across regulated industries and government agencies.

Carrier Partnerships

AT&T, Avaya, and other major carriers distribute RingCentral as the core of their UCaaS offerings — validating the platform's enterprise readiness while enabling RingCentral's international PSTN coverage in 40+ countries.
