RingCentral is a cloud-based phone and communications system that uses VoIP (voice over internet protocol) to run your business calls, texts, and video meetings over the internet instead of traditional phone lines. It runs through apps on computers, mobile devices, and optional desk phones, so you can use one number and one platform almost anywhere you have an internet connection.

Core idea

RingCentral replaces an on-site phone system (PBX) with a hosted service in RingCentral’s data centers that connects over your internet connection. Your users log in to the RingCentral app or use compatible VoIP desk phones, and all call routing, voicemail, and features are handled in the cloud rather than on hardware in your office.

What you can do

With a typical RingCentral plan you can:

• Make and receive business calls using local or toll‑free numbers, including extensions for each user.

• Send and receive SMS/MMS business texts and team messages, plus run HD video meetings and screen sharing from the same app.

• Use features like voicemail‑to‑text, call recording (on higher tiers), IVR/auto‑attendant menus, call forwarding, and call queues.

How it works day to day

A user signs into the RingCentral desktop or mobile app, which shows tabs for messages, video, and phone in one interface. To place a call, they dial from the app or desk phone, RingCentral connects it over the internet, and incoming calls follow rules you set (like ringing multiple devices, routing through an IVR, or going to voicemail). Admins configure numbers, extensions, call flows, and permissions centrally in a web portal, without needing to manage phone hardware on‑site.

Plans and add-ons

RingCentral offers multiple tiers (such as Core, Advanced, and higher bundles) that all include unlimited domestic calling and basic messaging, with advanced analytics, recordings, integrations, and contact center tools added at higher levels. It also sells specialized products like RingCentral MVP (message, video, phone in one), RingCX for contact centers, and RingCentral Events for running webinars or hybrid events.
