Competitive Landscape

Who RingCentral competes with, and how they differ.

Microsoft7.8/10

Bundles Teams Phone calling into Microsoft 365 enterprise suites rather than selling a standalone UCaaS platform, competing on all-in-one procurement and existing 365 seat penetration rather than communications-specific feature depth.

9 products reviewed on TopReviewed

Zoom Communications8.0/10

Built its base in video conferencing and expanded into Zoom Phone plus a broader "Workplace" collaboration suite, competing on freemium-led, self-serve adoption rather than RingCentral's enterprise contact-center and compliance focus.

8

8x8

The closest same-model rival: a similarly sized, publicly traded pure-play cloud communications provider (NASDAQ: EGHT) selling UCaaS and CCaaS bundled on a single platform, competing head-on for the same mid-market and enterprise UC contracts.

Cisco (Webex)7.8/10

Sells cloud calling (Webex Calling) primarily as an upgrade path for its large installed base of on-premise Cisco telephony and collaboration hardware, leaning on existing enterprise network relationships rather than cloud-native pricing.

Dialpad7.8/10

A smaller, AI-native cloud phone and contact-center vendor targeting the same SMB-to-mid-market segment, with a more startup-style, self-serve go-to-market than RingCentral's channel-partner and enterprise sales motion.

1 product reviewed on TopReviewed

Aircall7.9/10

Focuses narrowly on cloud call-center and support-desk phone systems for SMBs, integrated tightly into helpdesk/CRM tools, rather than RingCentral's broader UCaaS-plus-video-plus-messaging platform.
