The short answer

Quo, formerly OpenPhone, is a lighter phone system for small teams that share business numbers for calling and texting. RingCentral RingEX bundles phones, team chat and video meetings for companies of any size, including several offices and desk phones. Pick Quo for a small US or Canadian team that lives in shared inboxes; pick RingEX for one vendor covering calls, chat and meetings across sites.

Quo or RingCentral RingEX: our take

Quo gives each user a local or toll-free number, new or ported, and lets a team share numbers so several people answer one line together, with shared inbox threads, notes, call routing, phone menus and voicemail transcripts. Higher plans add AI call summaries, group calling and CRM integrations with HubSpot and Salesforce, and an AI agent called Sona can answer calls using paid usage credits. There is an API and an MCP server. RingEX gives each user a number with calling, voicemail, call recording and an AI virtual assistant, then adds team messaging and video meetings for up to 300 participants in the same app. Admins manage call queues, auto-attendants and multiple office sites from a web portal, and it works with desk phones.

On price, Quo starts at $15 per user/month billed annually, with a 7-day free trial. RingEX starts at $20 per user/month billed annually ($30 monthly), with Advanced at $25 and Ultra at $35 per user/month billed annually. CRM integrations and multi-site management need RingEX's Advanced plan or higher, and its entry plan includes only 25 SMS per user. Its free trial covers up to five users and excludes SMS. Quo's included calling and texting covers only the US and Canada; international use costs extra.

Both run on web, Windows, Mac, iOS and Android, so neither leaves anyone without an app. The difference is scope: Quo focuses on phone numbers and texting done well for small teams, while RingEX aims to replace a separate chat and meetings tool too, with add-ons for contact center, webinars and an AI receptionist.

Choose Quo if you're a small team that has outgrown a personal Google Voice number, texts customers a lot and wants shared lines at a lower starting price. Choose RingEX if you have several offices, want desk phones, or want phones, chat and video meetings from one vendor with central admin.
