The core difference
OpenPhone rebranded as Quo in September 2025, but the product underneath is unchanged: a mobile-first VoIP phone app built for small teams that want a real business number without a second physical phone [PR Newswire, checked via this site's Quo review, 2026-08-12]. RingCentral sits at the opposite end of the same market. Founded in 1999 and now sold as RingEX, it's a full unified-communications platform bundling voice, video, team messaging, and fax into one system built for companies that have outgrown a simple calling app.
That gap in scope, more than the price difference, is what actually separates these two products. Quo is deliberately narrow: phone calls, texting, and an AI agent, run from a phone in your pocket. RingCentral is deliberately broad: everything a 50-person operations team might need to replace a legacy phone system, a video conferencing tool, and a fax line all at once. Comparing their sticker prices without accounting for that gap in scope is how most vendor-neutral comparisons on this topic get it backwards.
Pricing, feature lists, and review data below were checked directly against each company's own pricing page and G2/Capterra listings on 2026-08-20, unless a different date is noted.
2026 pricing side by side
| Plan | Price (annual billing) | What it adds |
|---|---|---|
| Quo Starter | $15/user/mo ($180/yr) | 1 number/user, unlimited US/CA calling & texting, voicemail transcripts, Sona AI agent |
| Quo Business | $23/user/mo ($276/yr) | AI call summaries, group calling, HubSpot/Salesforce integrations, auto call recording |
| Quo Scale | $35/user/mo ($420/yr) | AI call tagging, dedicated onboarding, priority support |
| RingCentral Core | $20/user/mo ($30 monthly) | Unlimited US/CA calling, video up to 100 participants, 25 SMS/user/mo |
| RingCentral Advanced | $25/user/mo ($35 monthly) | Adds auto call recording, call monitoring (whisper/barge), CRM integrations |
| RingCentral Ultra | $35/user/mo ($45 monthly) | Adds 10,000 toll-free minutes, unlimited storage, video up to 200 participants |
At the entry tier, Quo runs 25% cheaper than RingCentral, $15 versus $20 a month per user. But the entry tiers aren't solving the same problem: RingCentral's Core plan already includes video meetings for up to 100 people, something Quo doesn't offer at any price. If your team never uses video, that's a feature you're not paying for either way. If it does, RingCentral's $20 tier is doing more work than the $5 gap suggests.
Quo adds two fees neither pricing page puts in the headline number: a one-time $19.50 carrier registration fee and a $1.50-3/month messaging fee, both charged by The Campaign Registry rather than Quo itself. This is a US carrier requirement that applies to any business texting platform using 10DLC numbers, not something unique to Quo, but it's easy to miss when comparing sticker prices side by side [Quo pricing page, checked 2026-08-12].
Where Quo wins
Quo's biggest advantage for a small team is what's bundled into that low starting price. Sona, Quo's AI voice agent, ships on every plan including the $15 Starter tier and can hold a full call rather than just route to voicemail, answering from a knowledge base the account owner builds and handing off to a human when it can't resolve something. RingCentral's comparable AI call features are gated behind its $35 Ultra tier or sold as an add-on.
Quo has also picked up an integration lineup RingCentral doesn't currently match at this price point: direct connections to Claude, Replit, Lovable, Supabase, and n8n, aimed at developers and small teams building AI-agent workflows around their phone number, alongside the more conventional HubSpot, Salesforce, and Zapier integrations [G2 Quo product page, checked via this site's Quo review, 2026-08-12]. For a solo developer or small agency already living in that toolchain, that's a different use case than the sales-team pitch either company originally built its name on.
On review volume, Quo also currently outscores RingCentral's flagship product: 4.7 out of 5 across roughly 3,399 G2 reviews, versus RingEX's 4.2 out of 5 across roughly 1,370 G2 reviews (both checked 2026-08-20). Reviewers most consistently credit ease of use and call quality, and the product is popular enough with very small businesses that the majority of its G2 reviewer base identifies as a company of 50 employees or fewer.
Where RingCentral wins
RingCentral's advantage shows up the moment a team's needs go past basic calling and texting. Video meetings scale to 200 participants on the Ultra plan, versus zero video capability from Quo at any tier. The integration marketplace runs past 300 apps, including Microsoft Teams, ServiceNow, and most major CRMs and help desks, a different order of magnitude than Quo's shorter, more curated list.
RingCentral's reliability claim is also the more substantiated one. Its Trust Center publishes a 99.999% ("five nines") uptime SLA for its core RingEX service, backed by service credits if it's missed, and the company reports twenty consecutive quarters of hitting that number [RingCentral Trust Center, checked 2026-08-20]. Quo advertises the identical 99.999% figure on its own security page, but without the same backing behind it: no service-credit remedy is spelled out, and no historical track record is disclosed [Quo, security page, checked 2026-08-20]. Third-party status monitoring (StatusGator, which tracks the public status page Quo maintains) recorded 16 incidents in the 90 days before this review, one major outage and 15 minor ones, with a median incident duration of roughly 10 hours [StatusGator, checked 2026-08-20]. Both companies claim the same headline number; RingCentral is the one that backs it with a contractual remedy and a reported multi-quarter record, which matters more than the matching percentage if uptime is a deciding factor.
RingCentral's admin controls are also built for a different scale of deployment: granular per-user permissions, detailed call analytics on the Advanced and Ultra tiers, and an admin portal designed for IT teams managing dozens or hundreds of seats. Quo's simplicity is an advantage for a five-person team and a limitation once headcount and configuration needs grow past that.
What real users say (G2, checked 2026-08-20)
RingCentral's review base has split across separate G2 product listings since the company reorganized its product line into RingEX (core phone/UCaaS), RingCX (contact center), RingCentral Events, and RingCentral Video. RingEX, the product this comparison covers, holds 4.2 out of 5 across roughly 1,370 G2 reviews and a matching 4.2 out of 5 across roughly 1,200 Capterra reviews. RingEX was ranked the #1 VoIP provider in G2's Spring 2026 rankings, up from #51 in 2023, a jump the company points to as evidence of recent product investment paying off. RingCentral's review base is now split across those separate G2 listings (RingEX, RingCX, Events, Video) after the 2025 reorganization, so the RingEX number alone doesn't capture every review RingCentral has collected across its full product line.
Quo holds the higher raw score, 4.7 out of 5 across roughly 3,399 G2 reviews, more than double RingEX's review count on the same platform. Reviewers most often cite the interface and call quality as reasons for switching from a competitor, RingCentral and Google Voice both come up repeatedly in that context.
The complaint patterns differ in kind more than in degree. RingCentral's most-cited issue is support responsiveness, long wait times and basic issues getting escalated to a second tier before resolution. Quo's most-cited issue, per this site's own Quo review, is account verification: new signups report being flagged for a compliance review shortly after signing up, sometimes with inconsistent explanations from different support replies [Trustpilot, checked 2026-08-12]. Neither complaint pattern shows up clearly in how either company markets itself, which is exactly why it's worth checking before you commit an annual contract.
Who should pick which
Pick Quo if you're a team of 1-20 people, want the lowest realistic starting price, don't need video conferencing built into your phone system, and like the idea of an AI agent answering calls on the cheapest plan rather than the most expensive one. It's also the stronger fit if your team already builds workflows around Claude, n8n, or Supabase and wants a phone number that plugs directly into that stack.
Pick RingCentral if you're past 20 employees, need video meetings or fax as part of the same platform, want a formally documented uptime SLA with service credits attached, or you're already standardized on Salesforce, Microsoft Teams, or another app inside RingCentral's 300+ integration marketplace. Our best business phone systems for small business roundup covers where both fit against Nextiva, Dialpad, and other alternatives if neither of these two is the final answer.
If RingCentral is already the frontrunner but you want a second data point before signing, our Vonage vs RingCentral comparison checks it against a different UCaaS competitor on the same pricing and reliability axes used here. And if RingCentral fits your feature list but the price is the sticking point, our Nextiva vs RingCentral comparison covers a third UCaaS option that sits between Quo's simplicity and RingCentral's full feature set. Full single-product detail on either company sits in our Quo (OpenPhone) review and RingCentral review.
Frequently asked questions
Is OpenPhone the same company as Quo?
A: Yes. The company took the Quo name on September 23, 2025, alongside a $105 million growth-funding round. Existing accounts, numbers, and data carried over automatically under the new name, per the rebrand announcement [PR Newswire, 2026-08-12].
Which is cheaper, Quo or RingCentral?
A: Quo's entry tier is $15/user/month versus RingCentral's $20/user/month on annual billing, per each vendor's own site as of August 2026. But at that $20 price point RingCentral throws in video calling for groups as large as 100, a capability that is missing from Quo no matter which plan you pick, so the cheaper sticker price isn't solving an identical feature set.
Is there an uptime guarantee behind either platform?
A: Both claim 99.999% uptime, but only one backs the number up. RingCentral's Trust Center documents it as a contractual SLA that pays out credits if the target slips, and says it has hit that mark for five straight years of quarterly reporting. Quo publishes that same 99.999% number on its security page too, though it stops there, nothing on offer if the target is missed and no past-performance figures to back it up, per a side-by-side read of both companies' own SLA pages in August 2026.
Which one has better G2 reviews?
A: Quo scores higher, a 4.7 out of 5 rating from roughly 3,399 raters, while RingEX sits at 4.2 out of 5 from about 1,370, per each product's G2 page as pulled in August 2026. Keep in mind that RingCentral broke its single G2 listing into four separate product pages, one each for its core phone service, contact center, events tool, and video product, in 2025, so this figure covers only the core phone product and leaves out whatever ratings the other three product lines have picked up.
Can Quo replace RingCentral for a growing team?
A: Only up to a point. Quo works well through roughly 20 users, but it doesn't offer video conferencing, fax, or the fine-grained permission and analytics tools RingCentral gives IT teams managing larger deployments, per each company's plan pages as reviewed in August 2026. Teams that outgrow those limits generally move to a fuller UCaaS platform such as RingCentral or Nextiva rather than staying on a scaled-up Quo plan.
What is Sona, and does RingCentral have an equivalent?
A: Sona is Quo's built-in AI voice agent, included on every plan, it draws on content the account owner sets up ahead of time and passes the caller to a person once it's out of its depth, per Quo's own published plan details (checked 2026-08-12). RingCentral has its own answer, transcription and live coaching among other things, but reserves the fuller set for subscribers on its top-end $35 plan or charges extra for it, rather than including it on every plan, per RingCentral's own published rate card (reviewed August 2026).
