RingCentral

RingCentral is a cloud communications platform (UCaaS) that unifies business phone, video meetings, team messaging, and SMS into a single system, so companies replace legacy PBX hardware and scattered tools with one app across desktop and mobile. Its flagship RingEX delivers enterprise-grade cloud calling with features like auto-attendant, call queues, IVR, voicemail-to-text, and call recording, along with HD video meetings and persistent team chat — everything a distributed workforce needs to communicate. Beyond core UC, RingCentral spans the contact center and AI. RingCX and RingCentral Contact Center add omnichannel customer support (voice, digital, and workforce tools), and RingSense AI brings call transcription, summaries, conversation intelligence, and an AI receptionist. Deep integrations with Microsoft 365, Google Workspace, Salesforce, HubSpot, and Zendesk embed calling and messaging into everyday tools, and open APIs let developers extend the platform. Reliability, global coverage, and compliance make it a common choice for mid-market and enterprise telephony. RingCentral serves businesses of all sizes replacing on-prem phone systems or consolidating communications. RingEX pricing is per user per month on annual terms — Core around $20, Advanced around $25, and Ultra around $35 — with contact center and AI add-ons priced separately, and volume discounts at scale. It competes with Zoom (Phone), Microsoft Teams Phone, 8x8, Dialpad, Nextiva, and Vonage, differentiating on its all-in-one UCaaS breadth, reliability, and integrations.
