#1 RingCentral
Best enterprise / all-in-one UCaaS
RingCentral suits mid-market and enterprise teams that want one UCaaS suite for phone, meetings, messaging, and a path into contact centre (RingCX). RingEX Core research floors start around $20 per user per month billed annually, with Advanced and Ultra higher; call recording, deeper CTI, and AI features often sit in Advanced+ or paid add-ons.
Seat dollars are frequently selector- or quote-gated, so published floors are medium confidence — confirm live pricing before you budget. Value scores 6/10 even as the product leads overall, because TCO climbs once AI and contact-centre options enter the stack.
