We’re confident that you’ll find the right solution for your requirements – whether you’re a solo entrepreneur, head of a sales team, or part of a large enterprise. Here are Tech.co’s top picks:
- RingCentral Office – Best for large scale businesses
- Zoom Phone – Best for small businesses with high call volume
- Ooma Office – Best for medium-sized businesses on a budget
- Google Voice – Best for Google Workspace users
After collating dozens of hours of research, we put together this article to highlight the best softphone apps for businesses. We’ve checked which options are best for features like cost, customizability, and security.
Expert Tip
If you’re committed to expanding your customer base, pairing your VoIP system with a CRM package is a no-brainer. Not only does the integration make it easy to share data across apps seamlessly, but it also lets you personalize each customer touch point to keep your client base happy.
RingCentral Office
- Best for large scale businesses
- Price from $20 per user, per month
RingCentral was the best softphone app in our research and it wasn’t exactly close. We found it particularly easy to use compared to other options, with a clean, intuitive interface that made navigating easy, mostly thanks to the intuitive sidebar menu. Adding contacts was especially easy, thanks to clear indicators under icons, which takes the guess work out of using the platform.
Arguably the best part of RingCentral is the vast library of third-party app integrations that allow you bolster the functionality of the softphone app as well as your other software that is often used by large-scale businesses. With over 200 software integrations, we were able to use RingCentral in a wide array of other platforms for easy communication. It’s worth noting, however, that a lot of integrations are reserved for the more expensive paid plans, so make sure your budget can handle it.
Check out our RingCentral review for more information
Pros
- Flexible range of pricing plans, with easy scaling for all businesses.
- Largest library of third-party integrations across our research.
- All-in-one hub for internal and external communication.
Cons
- No automatic downloads for video meeting transcripts.
- High starting price makes it prohibitive for smaller businesses.
- CRM and helpdesk integrations reserved for more expensive plans.
- Core plan: $20/user/month
- Advanced plan: $25/user/month
- Ultra plan: $35/user/month
RingCentral Office features
The VoIP provider proved to be a powerhouse when it comes to call management features, allowing us to everything from customizable call routing and ring groups to call screening and voicemail transcription. Even better, we found the transcriptions to be quite accurate compared to other solutions we tested.
On top of that, the analytics available through RingCentral Office were very extensive, allowing us to track a wide range of call and employee metrics. If your large-scale team is looking for a tool that can help you train your staff and scale your system, RingCentral could be your best bet.
The only downside we experienced while using the platform was the downloading meeting transcripts. The process is relatively easy, allowing you to simply press a button after a meeting, and you can set it to auto-download with a simple checkbox. Still, the transcriptions are downloaded in Notepad, which our team found to be a bit unprofessional.

RingCentral Office pricing
RingCentral Office is available in three plans: Core, Advanced, and Ultra. The prices discussed below are based on two to 20 users when paid annually.
- RingCentral Core – ($20 per user, per month) RingCentral’s cheapest tier supports up to 20 lines, and includes unlimited calls within the US/CA, voicemail-to-text transcription, messaging, document sharing, and 25 SMSs per month. Due to the plan’s line and SMS limits and lack of analytics, it’s ideal for small businesses running relatively simple operations.
- RingCentral Advanced – ($25 per user, per month) This plan includes everything in Core, with additional calling features like call barge, call whisper, call queues, and call monitoring. The plan increases it’s business SMS limit to 100 per user per month too, making it a great option for small to midsize businesses looking to expand, but potentially too basic for enterprise-level businesses with large quantities of data.
- RingCentral Premium – ($35 per user, per month) This tier will grant you access to RingCentral’s business analytics platform, plus unlimited storage, device-level analytics and alerts, and other advanced features and reporting functions enterprises need, such as end-to-end encryption for video meetings. Business SMS is 200 per user per month. Due to this tier’s extensive feature offering, it’s a great fit for companies that require advanced calling and growth tools like customer service businesses.
Learn more about the provider’s cost in our RingCentral pricing guide.
Who should use RingCentral?
- Businesses that make regular video calls
- Businesses that want to integrate softphone with other platforms
Who shouldn’t use RingCentral?
- Small businesses that need low cost integrations
- Businesses that heavily rely on meeting transcriptions
Zoom Phone
- Best for small businesses with high call volume
- Price: $10 per month
Our research found that Zoom Phone is the only VoIP solution that is close to providing a competitive softphone app to RingCentral. We found it very easy to use thanks to the clean, professional interface, and the Google integrations allowed us to get set up in minutes.
However, pricing was one of the factors that set Zoom apart in our VoIP research. The starting price of $10 per user, per month alone is a huge boon for small businesses, and an unlimited plan available for only $20 per user, per month, Zoom made a great case for us to use it when budget as at the top of the mind.
Check out our in-depth Zoom Phone review for more information
Pros
- Very low starting price, ideal for smaller businesses.
- Excellent for managing high numbers of incoming calls (spam prevention, hold music, etc.)
- Top tier security protocol with abundance of compliance certificates.
Cons
- Limited number of CRM and Helpdesk integrations.
- No email support available and you don't get much help with onboarding.
- Insufficient analytics tools with a lack of detail in reporting.
- Metered: $10/user/month
- Regional Unlimited: $15/user/month
- Global Select: $20/user/month
Zoom features
Zoom Phone offers the same huge selection of call management features and top tier training features, as RingCentral, netting it a similar score across our research. Even better, it offers all this while providing a more affordable platform, making it perfect for smaller businesses on a budget that still need to make a lot of calls.
Where Zoom shines beyond RingCentral is the hardware integration. While RingCentral has more software integration, Zoom Phone is compatible with far more phone hardware brands, which allowed us to operate the softphone on our desktop phones.

Zoom pricing
Zoom Phone has three pricing plans: the Metered, Unlimited, and Global Select.
- Zoom Metered – ($10 per user, per month) Zoom’s entry-level tier includes unlimited metered domestic and international calls, multiple device access, and domestic SMS services. This pay-as-you-go package is ideal for solo intruders and small businesses making the occasional international call. However, as its name suggests Zoom Metered charges extra for outbound calls so don’t be fooled by its low monthly cost.
- Zoom Unlimited – ($15 per user, per month) This plan contains everything in Zoom’s Metered package with unlimited regional calling and the option for users to pay extra for unlimited calling to 19 countries, rather than charging them for each outbound call. This makes the plan best suited to businesses making large numbers of global calls.
- Zoom Pro Global Select – ($20 per user, per month) This tier includes everything in Zoom Unlimited with Unlimited Regional Calling in one of the 48 Countries and Territories, with additional direct dial number features. This makes it a great fit for larger businesses making regular international calls.
You may have noticed that Zoom Phone is one of the cheapest on this list. In fact, it’s easily the best value, undercutting many providers on price while still providing a lot of features. Counterpath Bria Teams is the only noteworthy softphone app that’s more affordable, and it doesn’t have nearly as many features. Simply put, if value for money is important to you, Zoom Phone is a no-brainer.
Learn more about how much the softphone app costs in this Zoom pricing guide.
Who should use Zoom?
- Businesses with basic softphone needs
- Startups with smaller budgets
- Businesses already using Zoom for video conferencing
Who shouldn’t use Zoom?
- Businesses handling sensitive data
- Businesses using Zoom for the first time
- Larger businesses with advanced VoIP needs
Ooma Office
- Best for medium-sized businesses on a budget
- Price from: $19.95 per user, per month
The high starting price for Ooma may be a bit daunting for small businesses, but medium to large businesses can rest assured that the more expensive plans from Ooma are competitively priced at only $24.99 per user, per month and $29.99 per user, per month, while offering a big increase in featuring offering, like better training tools and more communication channels.
Ooma is a good all-around option. We found it easy to use and made it particularly simple when it comes to answering calls thanks to a robust and effective notification system. Beyond that, though, the feature and integration selection is definitely lacking compared to other options on this list, which we’ll go into a little more below.
Check out our Ooma Office review to learn more
Pros
- Easy to use interface for simple ingoing and outgoing calls.
- Seamless integration with Google Calendar.
- Automatic and voicemail screening available in all pricing plans.
Cons
- Third-party integrations only available on more expensive plans.
- White noise interference with voicemail audio quality.
- Can only invite users to video meeting with external link.
- Office: $19.95/user/month
- Office Pro: $24.99/user/month
- Office Pro Plus: $29.95/user/month
Ooma features
Ooma doesn’t particularly shine anywhere when it comes to features. It has fewer call features than RingCentral, more expensive pricing than Zoom, and fewer communication channels than Google Phone. Still, it offers more than enough to get by, with a respectable selection of call management features, a pricing model geared towards medium-sized and large businesses, and enough training tools to at least get you started with improving your system.
Ooma is pretty bad when it comes to integrations, though. It offers the worst selection of third-party app selection beyond Google Phone (which offers none), providing no customer service live chat, CRM, or helpdesk integrations. Even worse, it provides the least amount of communication channels in our research, with no team messaging functionality built into the platform.

Ooma pricing
Ooma offers three paid plan options for most businesses: Essentials, Pro, and Pro Plus.
- Ooma Essentials – $19.95 per user, per month
- Ooma Pro – $24.95 per user, per month
- Ooma Pro Plus – $29.95 per user, per month
Ooma also offers three enterprise-level plans that can get you started for larger businesses.
- Ooma Enterprise Standard – $19.99 per user, per month
- Ooma Enterprise Enhanced – $27.99 per user, per month
- Ooma Call Center – $49.99 per user, per month
Who should use Ooma
- Small and growing businesses
- Businesses with novice users that need assistance
Who shouldn’t use Ooma?
- Businesses that need robust security
- Businesses that need to be HIPAA compliant
Google Voice
- Best for Google Workspace users
- Price from: $10 per user, per month
Google Voice is the VoIP solution add-on to Google Workspace, meaning you’ll have to pay for both to get access to this softphone app. Still, it might be worth it if you’re after a service that is easy to use, as we found it offers an intuitive interface that is simple to figure out across the board. Plus, we were able to take advantage of small but delightful customization features, like the ability to give profile pictures to contacts and color-coordinate them within your directory.
Google Voice is an attractive offer if you already use Google Workspace, because it’s easy to get it set up and the price is quite low for the VoIP industry. On top of that, Google Voice offers one of the better feature catalogs and security offerings in our research. If you don’t use Google Workspace, though, it can be a big hassle, as you’ll have to migrate over your email, calendar, and video conferencing to the platform. Suffice to say, if you’re set up with a different business platform, another softphone app is likely your best bet.
Check out our in-depth Google Voice review to learn more
Pros
- Joint-lowest starting price ($10 per user, per month)
- Seamless integration with other Google Workspace tools
- Easy-to-use, clear interface
Cons
- Requires Google Workspace ($6 per user, per month)
- Limited customer support options in lower pricing plans
- Lacks training features like call monitoring and whisper
- Starter: $10/user/month
- Standard: $20/user/month
- Premier: $30/user/month
Google Voice features
For features, Google Voice was one of the better options, particularly for the price. Even with the most affordable plan, we were still able to access customizable call routing, call forwarding, and voicemail transcriptions. Even better, thanks to Google AI, the spam prevention was top notch thanks to automatic screening and call blocking with all paid plans.
One of the bigger downsides of Google Voice, however, is that it has a user limit on its most affordable plan. That’s right, if you want to pay only $10 per user, per month, you’ll only be able to have 10 users on the platform. For more, you’ll at least need to upgrade to the Standard plan, which costs $20 per user, per month. No other VoIP provider in our research had a user limit on any of its pricing plans.

Google Voice pricing
Google Voice offers three pricing plans: Starter, Standard, and Premier.
- Google Voice Starter – $10 per user, per month
- Google Voice Standard – $20 per user, per month
- Google Voice Premier – $30 per user, per month
To be clear, though, Google Voice is not a service you can sign up for on its own. You’ll have to be a Google Workspace customer already in order to add on the Google Voice functionality, which means the $10 per user, per month price tag is a bit misleading. In reality, the lowest price you’ll be able to pay is $16 per user, per month, because the starting price for Google Workspace is $6 per user, per month.
Who should use Google Voice
- Current Google Workspace users
- Those interested in possibly switching to Google Workspace
Who shouldn’t use Google Voice?
- Businesses that need third-party integrations
- Businesses that need lots of customer support
VoIP Softphones vs Hardphones: What's the Difference?
A VoIP softphone is a software-based phone that lets you make and receive calls over the internet, instead of using a traditional physical landline phone. You can use a softphone app on your smartphone or a desktop computer, making them a great fit for any business that offers customer service, sales, or support. They’re also the optimal choice for small businesses and start-ups as they’re more feature-rich, flexible, and affordable than alternatives.
Hardphones, on the other hand, are physical, hardware-based IP phones that resemble traditional desk phones. Like softphones, they run on IP technology, allowing users to access sophisticated calling features. They also charge users monthly subscription fees, instead of per-minute-rates charged by landline services. Hardphones offer marginally better connectivity and call qualities, making them ideal for businesses handling large volumes of calls.
What’s the Best Softphone App for iPhone and Android?
The best softphone app for iPhone and Android is RingCentral because it allows you to access plentiful features, low costs, and a vast number of integrations, no matter what device you use.
Again, RingCentral isn’t the only softphone app that works on the iPhone and Android. You might need a different set of features, a lower price point, or some different integrations that one of the other providers on this list. Every single provider on this list has an Android and iPhone app, so there’s no need to check on your equipment ahead of time.
Here’s a quick look at the interfaces you’ll get from RingCentral, 8×8, and Vonage (our top three picks).
You can also view the ratings and reviews on the App Store and the Google Play Store to further verify that the softphone apps are still maintained and functional, and that the features you need are included on the mobile and desktop versions. They’re all free to download, so if the VoIP service offers a free plan or free trial, you can use this to test out the mobile app.
Don’t forget to compare softphone providers to see how much it will cost your business.
How to Choose a VoIP Softphone App
Each business needs something slightly different out of a softphone. So, before investing in a new app it’s important to make the following considerations.
- Prioritize must-have features – Whether you plan to do with your VoIP softphone, businesses should be keenly aware of what VoIP features they need before selecting an app. Do you need AI time-saving features? Do you need advanced calling features like call screening and call transfer? These are all questions to ask yourself before choosing an app.
- Consider integrations – If you’re planning to integrate your VoIP softphone apps with existing business systems, you’ll need to make sure the products are compatible first. It’s also worth considering what extra integrations your business may benefit from in the future, to ensure the app will keep up with your needs in the long-term.
- Be mindful of extra costs – Most softphone apps have a straightforward pricing structure. However, it’s common for providers to charge extras for services like international calls and number porting. To avoid getting caught out by surprise bills, we’d recommend doing your homework before signing the dotted line.
- Research customer support options – Whether you’re new to VoIP softphones or well-versed in the technology, chances are you’ll require technical support at some point. To make sure you’re able to resolve issues fast, you should assess how regularly support is offered, and via what channels.
- Review security measures – VoIP security is a top concern for businesses in 2024. To ensure sensitive data is safeguarded, you should check for advanced features like end-to-end encryption, multi-factor authentication, and use permissions.
We take our hands-on testing and impartial analysis seriously, so you can have complete confidence that we're giving you the clearest, most useful recommendations.
After conducting an initial exploration to identify the most relevant, popular, and established business phone platforms on the market, we assessed ten of the top VoIP systems across 78 areas of investigation.
Based on years of market research, product testing, and user needs analysis, we've established a VoIP system testing methodology that scores each product in seven main categories of investigation and 16 subcategories. This covers everything from the features and security options available to the product's value for money and customer score, as well as much more.
Our main testing categories for VoIP phone systems are:
- Customer Score: the feedback and ratings given by customers who have used a particular VoIP system, as well as the wider reputation a VoIP software holds.
- Cost: the pricing structure associated with the VoIP service, including factors such as monthly subscription fees, domestic and international call rates, setup fees, hardware costs, and extra costs like add-on features or services.
- Features: the functionalities and capabilities offered by the VoIP service, including basic features such as call forwarding, and voicemail, as well as more advanced features like auto-attendant, conference calling, and interactive voice response (IVR).
- External Connections: the VoIP service's ability to connect and integrate with external systems or devices. This can include compatibility with existing phone systems, mobile devices, or other third-party software.
- Customer Support: the assistance and resources provided by the VoIP service provider to customers, including online resources, knowledge bases, and access to customer support representatives and AI chatbots.
- Security Options: Security options refer to the measures and features implemented by the VoIP service to ensure the confidentiality, integrity, and protection of voice communications and data.
- Scalability: the ability of the VoIP service to accommodate the growth and changing needs of an organization, including its capacity to handle a growing number of users, support multiple locations or offices, and scale up or down.
When it comes to calculating a product's final score, not all testing areas are weighted evenly, as we know some aspects matter more to our readers than others, which are merely "nice to have." After hundreds of hours, our process is complete, and the results should ensure you can find the best solution for your needs.
