Quo vs RingCentral

QUO VS. RingCentral

Quo vs RingCentral

Quo and RingCentral are two of the most-searched VoIP comparisons for growing teams, but they solve different problems. Quo is built for startups that want simple, app-based calling. RingCentral is built for larger teams that need a full unified communications stack. KrispCall sits between the two: enterprise-grade calling features at startup-friendly pricing, without the setup complexity of RingCentral or the limited feature set of Quo.

Quo logo

Quo (OpenPhone)

Quo, previously OpenPhone, is a cloud-based business phone system founded in 2018 for startups and small teams. It replaces traditional phone lines with an app-based calling and messaging platform.

Calls, texts, and contact management live in one cross-device app, giving distributed teams a single place to stay aligned. Shared business numbers and team inboxes replace isolated, single-owner phone lines.

Quo’s AI voice agent, Sona, answers calls, gathers caller information, and routes conversations automatically. Every plan includes 1,000 free Sona automation credits per month (roughly 10 AI-answered calls); heavier usage requires paid credit bundles starting at $25/month. Quo rebranded from OpenPhone in September 2025, and existing OpenPhone customers kept their plans and pricing through the transition.

RingCentral logo

RingCentral

RingCentral, founded in 1999, is an enterprise-grade cloud communications platform. Its track record and scale make it a common choice for organizations that prioritize stability over simplicity.

It unifies calls, messaging, video meetings, and internal collaboration in a single structured environment, backed by a 99.999% SLA uptime guarantee and over 10 compliance certifications, which matter for regulated industries like healthcare, finance, or legal.

RingCentral’s AI Receptionist, deep CRM integrations, and enterprise admin controls set it apart, but that depth comes with a steeper learning curve and more complex initial setup than app-based tools like Quo.

Quo vs RingCentral Comparison

Quo logo

Quo

Quo runs three plans. The Starter plan costs $15 per user/month billed annually, or $19 per user/month billed month-to-month. The Business plan runs $23/month annually ($33 monthly), and the Scale plan runs $35/month annually ($47 monthly). 

It also offers a 7-day free trial, and every plan includes Sona AI with 1,000 free credits/month. Extra numbers come with a small fixed fee ($5/month), which keeps budgeting simple for teams that want more lines.

RingCentral logo

RingCentral

RingCentral starts at $20/user/month (annual) or $30 monthly. Advanced costs $25 annually ($30 monthly) and Ultra costs $35 annually ($45 monthly).

Higher plans add more advanced features and AI add-ons that help larger organizations, but the structure can feel layered, and costs rise when you need more capacity than the base plan allows.

Winner

Quo

For small to medium businesses that need reliable voice and SMS communication without enterprise complexity, Quo delivers better value with more transparent plans that don’t nickel-and-dime you as you grow.

However, KrispCall offers a strong alternative with lower entry pricing and transparent billing with no hidden fees.

Quo logo

Quo

Quo provides unlimited U.S./Canada calling and texting*, shared and individual numbers, voicemail transcripts, call recording, auto-attendants, call routing, and a unified inbox for all telephony activity.

It includes CRM integrations, lightweight analytics, call forwarding, group calling, and simple automation. Its layout consolidates call and text history in one place for easy organization.

RingCentral logo

RingCentral

RingCentral provides a more expansion communications platform with calls, SMS/MMS, and voicemail, video meetings, and advanced call queueing. It supports fax, HD voice, and multiple device options for distributed teams.

Higher tiers add auto-call recording, advanced routing, large meeting capacity, video gatherings, monitoring tools, admin controls, device analytics, and broad CRM integrations.

Tie

Both Quo and RingCentral deliver strong feature sets, though each shines in different areas. Quo keeps things straightforward for teams that rely heavily on phone calls and text-based telephony.

RingCentral offers a broader range of tools for businesses that need video, heavier routing, and deeper administrative control.

Quo logo

Quo

Quo integrates with your existing tech stack, offering direct integrations with major CRMs like HubSpot and Salesforce, as well as collaboration tools like Slack and Gong.

Through Zapier, Quo connects to over 7,000 applications, and the Quo API lets you send automated messages, sync contacts and conversation data, and build custom integrations.

RingCentral logo

RingCentral

RingCentral offers over 500 pre-built integrations with top CRMs such as Salesforce, HubSpot, and Zendesk, as well as native integrations with Microsoft Teams, Google Workspace, analytical tools, and automation platforms.

It also supports custom integrations via its open APIs, enabling companies to build bespoke workflows or connect with niche tools.

Winner

RingCentral

RingCentral offers a far broader library of integrations, native enterprise tool connections, and its custom API-based capabilities that serve organizations with complex, multi-platform workflows.

Quo logo

Quo

Quo provides responsive support through email, in-app help, and a detailed knowledge base. Teams receive clear guidance for setup, number management, routing tools, and troubleshooting.

However, there are recurring complaints. Some users report long waits for replies, limited support channels (email or chat, with little or no phone support), and dissatisfaction when complex problems arise.

RingCentral logo

RingCentral

RingCentral offers 24/7 support via phone, chat, and a ticket portal, plus a comprehensive knowledge base. Larger plans offer onboarding help and dedicated account resources.

Yet many customers complain about long wait times, difficulty reaching a real person (many issues handled by AI or overseas support), delayed responses, and trouble canceling services.

Tie

Both platforms show inconsistent support experiences. Quo excels at onboarding and simple queries, but lacks phone support for critical issues.

RingCentral offers 24/7 availability, but users report being shuffled between agents and facing communication barriers with offshore teams.

Frequently Asked Questions

Not finding the answer you’re looking for? Reach out to our team or visit our help center.

Quo and RingCentral differ mainly in their scope, complexity, and target users. Quo focuses on app-based business calling, texting, shared numbers, AI tools, and team collaboration for small and growing businesses. RingCentral is a broader unified communications platform combining business calling, messaging, video meetings, advanced routing, analytics, desk phones, and a larger integration ecosystem.
Quo is better suited to teams that want a simpler phone-first platform, while RingCentral offers more depth for organizations with complex communication requirements.

 Yes. Quo is the new name of OpenPhone. The platform continues to provide cloud-based business calling and messaging, shared phone numbers, call routing, CRM integrations, and its Sona AI voice agent. So, businesses searching for OpenPhone vs RingCentral are comparing the same platform that is now branded as Quo.

 The best choice depends on your team’s size, communication needs, and geographic coverage. 

Quo is well suited to smaller teams that prioritize simple calling, texting, and shared-number collaboration. RingCentral is better suited to businesses that need a broader communications suite with video, analytics, advanced administration, and extensive integrations. KrispCall is a strong option for teams that prioritize international virtual numbers and advanced business calling features at a lower entry price. 

Quo starts at $15/user/month with annual billing, RingCentral RingEX starts at about $20/user/month annually, and KrispCall starts at $12/user/month annually.

Yes, Quo has a lower starting price than RingCentral when comparing annual entry-level plans. Quo Starter costs $15/user/month with annual billing or $ 19/user/month with monthly billing. RingCentral RingEX starts at about $20/user/month when paid annually.
However, the total cost can change depending on the plan, number of users, AI usage, messaging requirements, integrations, and additional features your business needs.

 Quo is generally the simpler option for teams that want an app-first business phone system. It works through desktop, web, iOS, and Android apps and does not require dedicated phone hardware.
RingCentral supports a wider range of configurations, including extensions, auto attendants, call queues, permissions, analytics, integrations, and IP desk phones. That flexibility can be valuable for larger organizations, but it can also involve more configuration than a simpler app-based phone system.

Quo is a strong choice when shared business texting is a central team workflow, while RingCentral is better suited to businesses that want texting alongside calling, video, and broader unified communications.
Quo supports business messaging, shared numbers, scheduled messages, auto-replies, snippets, and integrations for automated messaging. RingCentral also supports business SMS and MMS, but its RingEX Core, Advanced, and Ultra plans currently include 25, 100, and 200 SMS segments per user per month, respectively.

RingCentral offers integrated video conferencing, while Quo does not offer video meetings as part of its core business phone platform.

RingEX combines phone, messaging, meetings, and collaboration tools within one communications environment. Quo is more focused on business calling, SMS, shared numbers, AI call handling, and phone-related workflows.

For businesses that want calling and video meetings from the same provider, RingCentral is the stronger choice.

RingCentral has the broader native integration ecosystem, while Quo supports many of the applications commonly used by small and growing teams.


Quo integrates with tools such as HubSpot and Salesforce on its Business plan and also supports platforms including Slack, Zapier, Make, and its API. RingCentral states that it offers more than 330 integrations across over 200 companies, alongside APIs for voice, SMS/MMS, messaging, video, fax, and other communications capabilities.

 RingCentral provides more extensive analytics and reporting capabilities, while Quo offers simpler reporting for smaller and growing teams.
Quo includes analytics and reporting from its Business plan, helping teams understand calling and communication activity. RingCentral provides Business Analytics, Quality of Service analytics, adoption and usage reporting, device analytics, alerts, and optional Live Reports for monitoring queues and agent performance.
RingCentral therefore provides greater reporting depth for organizations managing larger or more complex communication operations.

Both Sona and RingCentral AI Receptionist can automate incoming customer calls, but their pricing and capabilities differ.
Quo’s Sona can answer questions, capture caller information, take messages, and transfer callers. Every Quo plan currently includes 1,000 automation credits, equal to about 10 Sona calls per month. Additional packages start at $25/month.
Sona supports English, Spanish, and French, but the language is selected for each Sona step. It cannot automatically detect a caller’s language or switch languages during a call.
RingCentral AI Receptionist can handle calls and SMS, answer questions, schedule appointments, capture leads, route conversations, and support call-queue overflow. It currently starts at $49/month as a standalone product or $39/month for RingEX customers, with 100 minutes included.

RingCentral supports IP desk phones, while Quo does not support traditional desk phones.
Quo is designed primarily as a softphone platform and works through computers, smartphones, and tablets. Its own documentation states that OpenPhone, now Quo, does not support desk phones.
RingCentral supports IP desk phones in addition to desktop, web, and mobile applications, making it better suited to offices that still rely on physical phone hardware.

Both Quo and RingCentral provide business-grade security controls, but RingCentral offers a broader compliance portfolio for organizations with more complex regulatory requirements.
Quo is SOC 2 Type II certified and uses encryption for data in transit and at rest. Business and Scale customers can also request a Business Associate Agreement for HIPAA-compliant use.
RingCentral maintains a wider set of enterprise compliance certifications and frameworks, including HIPAA, HITRUST, PCI, and GDPR-related controls. It also supports enterprise security capabilities such as SSO and other administrative controls.
Businesses in regulated industries should compare each provider’s current certifications against their specific legal and compliance requirements.

Quo’s main limitations are international phone number availability, lack of desk phone support, and plan-based access to some advanced features and support channels.
Quo currently provides new local and toll-free numbers only in the United States and Canada. Businesses can make international calls and send international messages, but they cannot currently purchase Quo phone numbers from other countries.
Quo also does not support traditional desk phones. Starter includes email ticket support, Business adds live chat, and Scale adds priority support and inbound phone support.

RingCentral can be more complex and potentially more expensive than a simpler business phone system when a small team does not need its broader unified communications capabilities.
Its Core plan currently includes 25 SMS segments per user per month, while Advanced includes 100 and Ultra includes 200. Businesses that need additional customer-engagement capabilities may also need paid add-ons such as AI Receptionist, Business SMS Booster, or Call Queues Booster.
For smaller teams focused mainly on calling and texting, that additional functionality may be more than they require.

No. Quo currently provides new phone numbers only in the United States and Canada. Businesses can use Quo for international calling and messaging to supported destinations, but international calling and messaging are billed separately and do not give the business a local Quo phone number in that country.

 Yes. Eligible Quo and RingCentral phone numbers can be ported to KrispCall, allowing businesses to change providers without replacing their existing business number.
The process may require details such as your account information, a recent billing statement, a signed Letter of Authorization, and other country-specific documents. KrispCall recommends keeping your existing provider account active until the port is completed.
Porting time varies by provider, number type, and country. KrispCall states that the overall process can take up to one to four weeks in some cases.
