OpenPhone Reviews: The Good, the Bad & the Best Alternatives

If you’re reading OpenPhone (rebranded as Quo) reviews, chances are you’re on the fence about using it. Perhaps it resembles a Google Voice upgrade with AI features? Maybe it feels like the simple fix your team has been waiting for?

When reviews paint a picture of OpenPhone based on users’ perspectives, it turns out that the VoIP phone system isn’t one-size-fits-all. OpenPhone reviews indicate that it works exceptionally well for small teams. For larger teams, the same platform led to struggles related to scalability and advanced feature requirements.

This article isn’t here to sell you the hype. Let’s dig into what real users are saying and whether OpenPhone is the smart bet or a shortcut you’ll regret.

What Is OpenPhone (now Quo), and How Does It Work?

OpenPhone has recently rebranded itself as Quo. It’s a VoIP-based phone system that integrates calling, SMS/MMS, voicemails, contacts, and team collaboration in one app. The system enables multiple teammates to interact through calls or texts using shared phone numbers and inboxes.

The system automates manual tasks, such as transcriptions and call summaries, with a built-in AI agent named Sona. It integrates with Slack, HubSpot, Zapier, and Salesforce to tie phone and messaging data to business tools. The system is a modern, mobile-first communications platform that supports small and growing teams, providing unified voice and messaging capabilities.

OpenPhone’s platform setup

Quo, formerly known as OpenPhone, offers native iOS (iPhone) and Android apps with a web and desktop interface. It doesn’t need physical hardware like desk phones or PBX boxes.

The overall system is flexible, helping you add new users and share access to numbers quickly. A key differentiator is the way Quo handles shared business phone numbers: Multiple team members share one number, and Quo syncs all calls, texts, and voicemails in a shared inbox.

When a shared number receives an incoming call, Quo rings all team members who have access to it. The first person to answer wins it and stops it from ringing for others. This line never shows as busy, as other team members can pick up or make calls while others are attending to an ongoing conversation on the same number. Typing indicators show when a colleague is drafting a reply, and team members can annotate a message or conversation in internal comment threads.

AI-powered features

Quo transcribes voicemails and generates call summaries to help you avoid admin work after calls. It provides you with options to configure auto-replies for incoming messages when no one is available. Moreover, Sona, the AI agent, keeps you available to answer calls 24/7.

It’s easy to insert Sona into your call flow. Sona uses NLP to understand intent and suggests follow-up questions based on the present context.

Integrations

Quo supports integrations with Zapier, Slack, HubSpot, Salesforce, and other business systems, enabling the automation of workflows and logging calls/texts to CRM. It offers custom contact fields, notes, and properties, helping you add CRM-like context to contacts. When you connect your CRM, it automatically logs calls and text messages, allowing your team to see all interaction history in one place.

The integrations here are lightweight as they link the business phone and CRM. It doesn’t focus on a full-blown omnichannel or heavy middleware ecosystem. Due to this, it lacks the depth that some enterprise systems might offer.

How does OpenPhone/Quo help a business?

Quo aims to accomplish the following tasks for a business:

• Replacing personal numbers with professional business lines: Rather than using a personal cell or Google Voice, you get local or toll-free numbers (US and Canada) in minutes. It lets you call or text from your devices using those business numbers.
• Giving distributed teams a shared inbox for calls/texts: Whether someone is remote, in the field, or off duty, the communication thread is centralized. Team members see all messages, voicemails, and call logs.
• Automating intake with voicemail transcription, AI summaries, and Sona: This allows teammates to read transcripts or summaries. Sona pre-screens calls, asks essential questions, and escalates when needed, saving time and avoiding losing details.
• Offering quick, low-friction setup: You don’t need to buy routers, PBX boxes, or business phone handsets, and there’s no need to worry about wiring. Everything lives in the cloud.

Overall, OpenPhone positions itself as an upgrade over legacy systems or informal solutions for delivering a business-grade phone and messaging experience. It’s simple, fast, AI-powered, and easy to implement.

Despite all the positives, there‘s some criticism related to OpenPhone’s sparse accommodation for enterprise readiness and compliance requirements. Around 3,000 users have rated it an average of 4.7 stars out of five on G2. In the next section, we’ll explore these reviews in detail, not just those on G2, but in the majority of places where actual users have given feedback on OpenPhone.

What Reviews Tell Us About OpenPhone Features

Below is an overview of OpenPhone’s features and qualities as discussed in reviews on multiple platforms.

Ease of use

Users have praised OpenPhone for its design and simplicity. They feel more organized having their texts, calls, and voicemails in one place. Smaller teams find the shared inbox features useful, as they can view the full communication history in a single thread.

Overall, OpenPhone works well, even for those without technical expertise.

Customer support

In G2 reviews, users list customer support as the top pro, with 331 mentions among 2,992 reviews. Customer service also shows very strong satisfaction, with 239 mentions as of September 25, 2025.

However, if you filter for one-star or zero-star reviews, you’ll see 21 of them, and almost all of them complain about customer service and support, as well as other issues. Among 2998 users, if 21 have a problem with support, that’s roughly 0.07% of its users. OpenPhone has addressed some of these concerns, which is a positive sign.

Capterra had only 60 reviews of OpenPhone. Trustpilot has nearly 650 reviews, with an average rating of 4.1 out of 5 stars.

OpenPhone has been pretty responsive on Trustpilot. The company has responded to 97% of negative reviews, typically within a week. Based on OpenPhone’s responses, it seems to have issues related to disabling accounts. However, OpenPhone encourages users to submit support tickets for resolution.

Based on reviews, it appears that users require more consistent and prompt responses from the business, rather than a delayed resolution.

What matters if you’re evaluating support

Set the right expectations from the start, and get clarity on the mission-critical things. Some users report having difficulty reaching human support or experiencing inconsistent responsiveness. It’s advisable to lock down your escalation path, response targets, and supported channels in writing before beginning rollout.

The most common complaints aren’t about “rude agents”. There are call quality/connection hiccups that force tickets. Run a trial under real traffic conditions, including calling regions, device mix, and bandwidth constraints, to minimize false negatives in support.

Platform features

Reviewers cite OpenPhone’s feature set as a significant advantage. It offers typical VoIP functions with transcription and an auto-attendant. Users love the shared number model, calling it “chat channels”, because anyone can join or leave as needed. It allows seamless team collaboration on different phone numbers.

On G2, many users have praised the AI transcription and summary features, finding them helpful for faster follow-ups. Similarly, this is a common trend in Trustpilot reviews. Multiple recent reviews have found AI summaries to be genuinely beneficial for productivity.

OpenPhone caters to various use cases, including sales, support, and recruiting. However, the tool caters mostly to the necessary and fundamental feature requirements. For more complex needs, such as a power dialer, you may need a different phone option.

There are a few mentions of the lack of availability of a desktop app for Chromebooks or a properly functioning mobile app. Some reviews point toward a lack of reliable support. However, everyone has their own perception of support, which is largely subjective.

Reviewers do point out a few feature gaps, for example:

• No support for desk phones: Some retail/office spaces have IP desk-phone hardware and expect their business phone systems to support it.
• Lack of a built-in spam caller ID or robocall blocking: Unlike with other competitors, business calls only show phone numbers, unless you previously saved the caller’s ID. This feature used to work, but no longer does, according to a review on Reddit.

If you’re considering OpenPhone, please ensure to check the availability of all features critical to your workflow.

Setup and phone numbers

The company offers a free seven-day trial. However, it’s not as easily accessible as it first appears. You need to keep a few things handy before you can experience the product, for example:

• Business name, industry address, and EIN
• Business website and/or public-facing social media accounts
• Brief description outlining the purpose of your Quo usage
• Copy of your government-issued ID

After entering your credit card details, you might not be able to access the product unless you send these details to Quo, formerly known as OpenPhone.

This isn’t necessarily a negative thing. It’s simply a blocker in the process. The company is verifying genuine users, which is actually a good sign.

Based on OpenPhone reviews, the initial setup is relatively straightforward for basic use. During signup, you can choose between local and toll-free numbers. To begin with, the system gives you a random number, but you can choose from a list like this:

However, if you opt for number porting, it may be a slow and cumbersome process. A review on Reddit suggests that OpenPhone took nearly a week to bring in a number, and it was a nightmare to transfer a number out. This review was five years ago. However, a 2025 G2 review also expresses concerns over number porting.

Additionally, obtaining account details/PINs for port-out is not a self-service process. You must submit a form and wait approximately 48 hours for the info, which one admin found very frustrating. If keeping your existing number is mission-critical, be aware that moving numbers to/from OpenPhone may require patience.

However, if you seek a more conclusive picture, among 2998 reviewers, around 234 users have reported a positive experience. Some users may simply have experienced a few hiccups during product setup.

Administration and scalability

OpenPhone numbers aren’t tied one-to-one with users. They scale well for the team, as many employees share access. OpenPhone offers a channel-style view, making it easy for people to join or leave conversations.

On the billing front, OpenPhone’s per-user pricing might be a little inefficient if you want three to four employees to share one number. You’ll still have to pay per employee, which may pose some scalability challenges. This per-user model is standard for cloud phone services; however, buyers should plan their licensing accordingly.

Overall, in terms of reliability at scale, Quo (formerly OpenPhone) handles moderate call volumes effectively for most users. A reviewer on G2 has appreciated the platform for keeping them organized and professional as they scaled.

OpenPhone has proven capable for small and mid-sized organizations. However, huge enterprises or those requiring complex call center features might find their admin feature set somewhat limited.

Pricing, contracts, and cost of ownership

On G2 and Capterra, customers frequently mention competitive pricing and value. OpenPhone’s plans are straightforward.

Check out OpenPhone pricing in detail.

It has a flat per-user monthly fee, starting around $15 for its Starter plan. Several users chose OpenPhone after comparing costs and realizing they were paying for unnecessary features with other systems.

On the other hand, some users believe Quo should be more transparent regarding its pricing, particularly about additional costs. Although there are minimal extra costs, users prefer a more up-front approach.

However, Quo has made its pricing page more transparent (image below from October 1, 2025). This shows that the business takes feedback seriously and acts on it.

Security, compliance, and reliability

OpenPhone operates in the cloud, so reliability and compliance are crucial. Call and text reliability gets mixed feedback. Many users report clear call quality in daily use and a stable uptime. Some users in recruiting have noted that the system accurately records calls, with no distortion or noise.

In community discussions, call latency or one-way audio issues caused by weak internet or cell connection were recurring themes. Some reported frustrating call failures. However, these cases might be outliers related to specific carrier or network problems.

In terms of platform uptime, OpenPhone has generally been reliable. OpenPhone utilizes reputable carrier partners to route calls/texts, and when issues arise, they often stem from these upstream carriers.

On the security and compliance front, OpenPhone strictly enforces messaging regulations and terms of service. A user observed that many of the loudest complainers were individuals who had openly violated OpenPhone’s terms and were upset that they had been caught.

OpenPhone takes compliance seriously and maintains a zero-tolerance policy for spam. Legitimate businesses surely benefit from this. However, just to be on the safe side, it’s best to ensure you do the following:

• Confirm policies on compliance: Enquire about the cold calling norms and industry restrictions applicable to your case. Also, touch base on the SMS registration requirement up front.
• Confirm SLAs: Observe and evaluate the response time and escalation route before you commit to them.

Who Is OpenPhone Best Suited For?

If we assess G2’s Quo reviewer pool on OpenPhone’s category page, it suggests that the majority of its user base is in the small business segment. Statistically, among 2998 reviewers, 2738 users are in the small business segment, 221 are in the mid-market, and only 36 users are in the enterprise market segment.

The reviews also state the same, but with more context. OpenPhone, now known as Quo, is ideal for teams that need shared lines, modern apps with AI features, and transparent pricing. The reviewers typically come from law firms, real estate consultancies, and other small businesses.

If you’re currently using Google Voice

If you’re currently using personal cell phones or Google Voice to run your business communications, OpenPhone is a big step up in terms of professionalism. As with Google Voice, a team of three people would need to share a login. However, OpenPhone offers shared access to a number with AI summaries and transcription.

If you’re carrying a business and a personal phone

Because OpenPhone works on iOS, Android, and the web, it’s ideal for teams on the go or any business with distributed teams. You no longer need to carry two phones, as OpenPhone allows you to use your personal device with a separate business number/app.

If your team already works on smartphones and laptops, OpenPhone seamlessly integrates into that workflow. Conversely, if your staff members sit at fixed desks all day and prefer desk phones, OpenPhone might be less ideal.

If you’re budget-conscious

If you’re a buyer looking to keep costs low while scaling your communications, OpenPhone is the ideal solution. Nonprofits, independent consultants, and small clinics have noted the excellent price-to-feature ratio. There’s no expensive PBX hardware, just an app. Overall, OpenPhone is ideal for small to mid-sized businesses that prioritize flexibility and teamwork, which is evident from the review diversity mentioned earlier.

Who Should Consider Alternatives to OpenPhone?

OpenPhone might not be the perfect fit for everyone. Based on the patterns in user feedback, you might consider other OpenPhone alternatives if you fall into any of these categories:

• Businesses requiring desk phones or analog devices: If your office workflow relies on physical desk handsets or legacy fax machines, OpenPhone may not be the best fit. It does not natively support VoIP desk phones or ATA adapters.
• Larger enterprises or call centers needing advanced features: Enterprises or specialized call centers that outgrow OpenPhone’s feature set may require more advanced capabilities. For instance, if you need complex automatic call distribution queues, call analytics dashboards, or a power dialer for high-volume outbound calls, OpenPhone’s lightweight feature set may fall short.
• Users demanding 100% reliability: Companies that require every single call to be flawless may consider a more analog or hybrid solution. While many users have perfectly fine call quality on OpenPhone, some have reported latency and call drops, as mentioned earlier.
• Users needing hands-on support or consulting: OpenPhone is a lean service with support primarily via chat/email. If your team is not tech-savvy and you don’t have an IT person, you may need to weigh this. Many find OpenPhone easy enough to use on their own, but if you know you’ll regularly want to pick up the phone and call for help, a more service-oriented vendor may be a better option.

Companies with traditional phone habits, large-scale operations, or a requirement for concierge-level support might need to explore other options.

Top Alternatives to OpenPhone

Below are the top three alternatives to OpenPhone on the market.

1. Nextiva

While OpenPhone gives you features like calling, texting, and basic chat, it leaves gaps for video conferencing and social media. As you scale, you’ll need these channels to ensure decent customer engagement. Nextiva provides a unified customer experience platform that supports all communication channels from a single platform.

It delivers advanced features, including analytics, a shared team collaboration space, and advanced automatic call distribution. The platform comes equipped with auto-dialers and deep integrations with CRMs and other business tools. This drives consistency in customer experience, as everything is under one roof, reducing context switching and avoiding integration breakdowns.

Below are some key highlights of Nextiva that make it the communications platform of choice:

• Reliability: Nextiva strives for 99.999% uptime while using redundant infrastructure across multiple data centers.
• Capabilities: Nextiva provides call routing, power, predictive dialer, conferencing, integration, and lots of advanced features in one package. You don’t need to spend extra on managing multiple vendors for your communication requirements. You get IVR, omnichannel contact center tools, and analytics from day one.
• 24/7 customer support: Nextiva offers fast resolution times and assistance from human agents, regardless of the plan you’re on.

For more clarity, let’s imagine a scaling sales team that starts with OpenPhone because it’s cheap and lightweight. As soon as they run into 10–15 reps, they see the following:

With OpenPhone (Without Nextiva)	With Nextiva
Missed sales calls because you can’t define priority routing or overflow rules.	A single dashboard handles calls, SMS, video meetings, and chat. You get to configure IVR flows and queue overflow logic.
Lack of visibility into call trends or which reps underperform.	Real-time dashboards give insights into call volumes, wait times, and agent performance.
Frustration when urgent support issues can’t be escalated beyond ticket-level responses.	Support is available 24/7 via phone, and issues are resolved collaboratively, not through one-size-fits-all scripts.

2. Dialpad

Dialpad is often seen as a more innovative alternative, particularly for teams that prioritize AI, transcription, and advanced analytics. Since it has an in-house LLM, DialpadGPT, Dialpad is less prone to inaccuracies or hallucinations in voice transcriptions.

Dialpad also offers an all-in-one communication stack with contact center functionality and real-time coaching. The platform is capable of layering advanced features as your business scales.

Below are a few key features of Dialpad that make it a strong alternative to OpenPhone:

• AI-powered voice intelligence has real-time transcription, call summaries, sentiment analysis, and keyword tracking.
• Quality of service dashboard monitors call quality with a mean opinion score to spot issues quickly.
• AI coaching tools give live suggestions and feedback during calls to help agents improve on the spot.

Overall, Dialpad is a strong communication platform for SMBs, but it is pricier than OpenPhone.

3. Grasshopper

Grasshopper is an ultra-lightweight alternative in this lineup. It’s ideal when simplicity, cost, and fundamental professionalism matter. Although it may not offer advanced features, you can get started in minutes without dealing with a complex configuration.

Because its features are basic and its plans are flat, Grasshopper’s costs are easier to predict. It’s well-suited for freelancers, startups, solopreneurs, or entrepreneurs in small local businesses, but not for heavy inbound call operations.

Below are some key features of Grasshopper:

• Virtual business numbers: You can choose from local, toll-free, or vanity numbers, or you can port your existing number.
• Desktop and mobile apps: These allow you to manage phone calls, missed calls, texts, voicemail, etc. across your phone, tablet, or computer.
• Call forwarding and transfer: You can route incoming calls to devices or team members as configured.
• Simultaneous call handling: This rings multiple devices or lines at once so you don’t miss calls.

Overall, Grasshopper offers fewer features but is very straightforward, which complements the interests of a small team.

Pros and Cons of OpenPhone

Here’s a quick overview of the pros and cons of OpenPhone based on user reviews:

Despite the cons, the affordability factor keeps OpenPhone top of mind in use cases common in small or medium-sized operations.

How to Evaluate OpenPhone and Its Alternatives

Below are some questions drawn from real user experiences of the VoIP phone system. Answering these questions will help you effectively evaluate OpenPhone and other alternatives.

1. How will your team use the phone system on a day-to-day basis?

Ensure you understand the daily workflow of your team members. At the same time, consider the present and future needs of your business unit. It’s best to look to the long term with scalable solutions such as Nextiva, which empowers your daily workflows with a comprehensive suite of communication tools at an affordable cost ($15 per user per month for the Core plan). It costs the same as OpenPhone, but it delivers much more.

If you need multiple team members to handle calls and texts from a single number, OpenPhone is a good option. However, if your communication spans beyond calling, SMS, and basic chat, you might need an all-in-one communications platform.

2. Do you require desk phones or specialized hardware?

OpenPhone is app-based (mobile and desktop), so ensure you’re comfortable using smartphones or computers for calls. If you prefer receptionist phones, conference room speakerphones, paging systems, or fax machines, you’ll need to find workarounds or look for another provider.

3. How critical is ultrareliable call quality for you?

Consider your tolerance for occasional VoIP disruptions. Most users find the call quality good, but if even a small chance of a dropped call or slight voice delay is unacceptable, you might need redundancy. It’s best to opt for systems that deliver high uptime and, most importantly, maintain logs to document this.

4. How soon do you need to port existing numbers, and can you afford any downtime?

Porting can take several days, even for OpenPhone. Can you stop using the number for a week, if not more? It’s best to set up call forwarding to avoid missing any opportunities. Use the seven-day free trial with a temporary number to test the features.

5. What integrations or API access do you need?

Make a list of other tools you use, like CRM or helpdesk, and see if OpenPhone has native integrations for them. It offers integrations with HubSpot, Salesforce, Zapier, and others, which users find valuable. If an integration is not available, are you comfortable using the OpenPhone API or Zapier to bridge the gap?

6. Do you operate in a regulated environment?
If you need HIPAA-compliant communications, for example, confirm whether OpenPhone will sign a business associate agreement. For financial services, consider whether call recordings and logs meet your record-keeping requirements. These questions will help identify potential matches and mismatches between features and your requirements.

Choose a Business Phone System for Today and Tomorrow

OpenPhone wins points for its shared lines, modern features, and affordable pricing. But the cracks show up quickly. Reviews suggest it’s a simple phone system that’s good for small or mobile-first teams. However, enterprise-grade support and scalability seem to be missing.

If you have a small team and are looking for a simple solution, OpenPhone is a good fit. However, will you always be a small team of two to three people?

Currently, OpenPhone lacks advanced features such as auto-dialers and other functionalities, so it doesn’t scale to meet your team’s requirements as you grow. It’s best to opt for a solution that caters to today’s needs while also promising support for future requirements.

Nextiva delivers an all-in-one solution for all requirements, ranging from the simplicity of SMBs to the sophistication of Enterprises. It also starts at the same cost as OpenPhone, $15 per user per month for the Nextiva Core plan.
