What users say about Quo
Honestly, it’s way too expensive, and the fact that every new user is another new price is ridiculous. Approval and verification took forever. – Addison H. Owner, G2 review
Not a very good platform for a larger office like ours. I would beware customer service hours are sparse and hard to reach someone. The trial period limits your opportunity to evaluate the platform and service sadly, Quo fails small businesses. – A Mac, Trustpilot review
My overall experience with OpenPhone wasn’t the greatest. Their customer service was always there to help, but there just wasn’t a lot they could do. – Thomas F, System engineer, Capterra review.

- Basic feature set compared to dedicated phone system providers.
Which Quo (OpenPhone) alternative is best for you?
Choosing the right Quo (OpenPhone) alternative depends on your specific business needs, budget constraints, and communication priorities. To find your perfect match, identify which scenario best describes your situation:
- If your team is expanding globally, opt for KrispCall. Virtual numbers in over 100 countries with competitive international rates enable you to establish a local presence anywhere without the premium costs typically associated with global expansion.
- If you’re tired of dropped calls and unreliable service, go with Nextiva. That 99.999% uptime guarantee ensures your phones actually work when customers call, unlike the connectivity issues plaguing Quo users.
- If your sales team makes 50+ calls daily, go with Ringover. Power dialer, local presence, and call campaigns help your reps connect with more prospects in less time.
- If you want your phone system to coach your team, go with Dialpad. AI analyzes every conversation, suggests responses in real-time, and identifies coaching opportunities automatically.
- If you’re running a large organization with complex needs, go with RingCentral. When you need to integrate with dozens of business tools, support multiple offices, and scale to hundreds of users, RingCentral’s enterprise infrastructure handles complexity with ease.
- If you want simplicity and traditional desk phone support, go with Ooma. Plug it, configure basic settings, and start taking calls with full support for physical office hardware.
- If you’re budget-conscious but won’t accept poor quality, go with Vonage. Carrier-grade reliability and 24/7 support, starting at $13.99/line, prove you don’t need to choose between affordability and dependability.
- If you need highly customized communication solutions, go with GoTo Connect. Custom packages mean you’re not paying for features you’ll never use or missing capabilities you desperately need.
- If your team is deeply invested in Google Workspace, go with Google Voice. Seamless integration with Gmail, Calendar, and Contacts eliminates learning curves and creates a unified experience for Google-centric teams.
- If you’re already paying for Zoom Meetings, go with Zoom Phone. Why manage two vendors when you can unify voice and video for $8/month? Escalate calls to video meetings with one click in the interface your team already knows.
Note: We recommend taking advantage of free trials or demos to test your top 2-3 candidates with actual team members before making your final decision.
Is KrispCall the best alternative to Quo for your business?
If you’ve read this far, you’ve seen how each Quo (OpenPhone) alternative tackles different business needs. But here’s the reality: most businesses leaving Quo need three things that aren’t negotiable: reliable call quality, advanced features, and pricing that won’t shock your CFO when you scale past 20 users.
That’s exactly where KrispCall delivers.
At $12/user/month, you get AI coaching, a power dialer that triples your team’s productivity, and virtual numbers from 100+ countries, without the premium international rates other providers charge. KrispCall is built for businesses outgrowing basic tools but not ready for enterprise complexity or enterprise bills.
Think about what’s frustrating you about Quo right now. Dropped calls during important customer conversations? Submitting support tickets and waiting for days for responses? Missing features like call monitoring that your sales manager keeps requesting? KrispCall solves all of these without requiring you to become a VoIP expert to manage complexity.
