VoIP Softphones vs Hardphones: What's the Difference?

A VoIP softphone is a software-basedphone 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.

Softphone pricing can vary depending on how many users you need, which provider you opt for, and what kind of features you need. Pricing can range from $5 to $22 per user per month, with some providers offering unlimited users for a larger monthly fee such as $450, or even a one-time fee for long term use.

Yes, you can use a softphone for an international call, but it could end up costing a bit more than domestic, depending on your provider. Almost all of them will give you specifics on where you can call and for how much.

9 Best Softphone Apps For 2024

If you already use one of the best business VoIP providers, you’ll probably have a softphone app included with your service package. If, for example, you’re already signed up with RingCentral, it would make sense to stick with its app because it will offer optimal integration with your existing phone system.

Alongside these provider softphone platforms, we’ve also listed several other standalone apps that can be used regardless of which VoIP service you use. 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:

  1. RingCentral Office Best overall softphone app for businesses
  2. 8×8 Softphone App best for sales teams
  3. Zoom Best value for money
  4. Vonage Best for training features
  5. Counterpath Bria Teams Best for team collaboration
  6. Zoiper 5 PRO Best for businesses handling sensitive data
  7. GoToConnect Best for businesses with large call volumes
  8. Line2 Best starter phone
  9. 3CX Softphone Best for Windows 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. However, we’d advise getting a free quote tailored to your business (it takes less than a minute!) so you know exactly how much you’ll be paying.

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.

The RingCentral softphone application is the best choice for most businesses because it offers the best customer support, is highly scalable, and has strong external connectivity – ensuring it will work alongside your existing software and infrastructure.

RingCentral’s softphone app operates on web, desktop, or mobile (Windows, Mac, iOS, and Android). It also provides a seamless, high-quality experience, whether you need it for video or audio call softphone functionality. The app is free, but you’ll need to sign up to RingCentral Office to use it.

RingCentral Office features

RingCentral competes with the best video conferencing platforms on the market.

The app is bound to improve your team’s communication and collaboration, and is worthy of the top spot on this list. With a 4.5-star average customer rating across the App Store and the Google Play Store, it seems most users would agree with us.

RingCentral lets you switch devices during a call, as well as access files and add guest users all of which are super useful and make the overall call experience smoother. There are voicemail-to-text and voicemail-to-email options, and you can even listen to your voicemails inside your web browser.

RingCentral also has a vast range of CRM integrations that will let you streamline your calls, and ensure all your data and information is being pulled through to the right places. Specifically, RingCentral offers more than 96 CRM integrations and syncs seamlessly with helpdesk options like Salesforce, Zendesk, HubSpot, and Freshdesk. However, unlike 8×8 which offers CRM integrations in its cheapest package, RingCentral users wanting the capability will need to upgrade to its middle-tier package, which costs $25 per month.

Find out if this is the right provider for your business by using our free comparison tool, which will match you to a softphone app based on your answers to a few quick questions about your business.

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.

2. 8×8 Work

  • Best for sales teams
  • Price from $24 per user, per month

8×8 is an industry-leading VoIP system and our best pick for sales teams, due to its powerful sales, collaboration, and security features. However, you’ll have to fork out for one of its pricier packages to unlock advanced calling features like call whispering and barging, making it slightly less cost-effective than apps like Vonage that offer these capabilities in their entry-level tier.

8×8 Work features

8×8 team messenger and web conferencing features make it easy for teams to communicate from afar. The provider even lets users share files seamlessly through chat messages with its document-sharing feature – a capability that leading providers like Zoom and DialPad are currently missing.

8×8 is particularly good for managing high volumes of inbound calls thanks to features like a virtual receptionist, a call queue function, and the ability to create ring groups. The call queue is particularly important because it allows you to keep inbound callers on hold even when an agent isn’t available.

The provider is ideal for growing businesses that need to upskill staff quickly, too. From call recording and monitoring, 8×8 offers several training features, and its customer support service – which earned a perfect 5/5 help & support score in our research – provides a lifeline to users getting to grips with the service too.

8×8 isn’t perfect though. The provider’s entry price is higher than RingCentral, making it slightly less appropriate for businesses looking for a budget softphone app. Read more about the softphone in our full 8×8 pricing and featuresguide.

8×8 Work works on iOS, Android, Windows, and Mac. However, this is not a standalone softphone and is only available to those with a paid 8×8 X Series subscription or a free 8×8 Express trial.

8×8 pricing

8×8 offers five different pricing plans: the X2, X4, X6, X7, and X8.

  • 8×8 X2 ($24 per user per month) This plan includes features like voicemail transcription, single sign-on, and call activity analytics, unlimited calling in 14 countries, and unlimited calling within the US and Canada. International calls come at a premium, however, making it a better fit for businesses only making domestic calls.
  • 8×8 X4 ($44 per user, per month) This tieroffers robust analytics along with unlimited calls to 48 countries, and includes even more communication features than the X2 plan such as call barge and call whisper. X4 is a great fit for most global businesses, but those in need of enhanced growth features will be better off upgrading to a pricier tier.
  • 8×8’s Contact Center plans the X6, X7 and X8 incrementally increase access to additional business features. The X6 plan ($85 per user, per month) lets you access call activity analytics, superior analytics, contact center reporting and analytics, and single sign-on.
  • 8×8 X7 ($110 per user, per month) This package adds omnichannel routing of voice, chat, emails, SMS, social media, and messaging applications.
  • 8×8 X8 ($140 per user, per month) This plan includes features like an autodialer, quality management, and speech analytics.

Plan X8 and above are designed for businesses that lean heavily on VoIP systems like call centers but will likely exceed the budgets of most small firms with mid-range VoIP needs.

What's new for 8x8?

January 2024: You’ll now be able to have interactions with customers with the 8×8 integration for CRM platforms Salesforce and Microsoft Dynamics.

Who should use 8×8?

  • Businesses making high volumes of internal calls
  • Sales and customer service businesses
  • Businesses that regularly onboard and train staff

Who shouldn’t

use 8×8?

  • Small businesses with limited VoIP needs
  • Businesses making lots of international calls

3. Zoom

  • Best value for money
  • Price: $10 per month

Zoom saw a meteoric rise during the pandemic thanks to its notable ease of use and affordability, making it the go-to option for video chats. It boasts an incredible 3.3 trillion meeting minutes each year.

Zoom has been adding to its business offerings over the past few years, and Zoom Phone represents an excellent VoIP option with a solid softphone app. In our research, Zoom Phone ranked highly across most categories, netting an overall score of 4.4/5, taking the third sport in our ranking.

In fact, Zoom Phone was considered the best value option in our VoIP research with a 5/5 value for money score, which is saying something considering the competition.

Zoom features

In addition to a low starting price, all of its plans offer an array of inbound communication features, including voicemail-to-text, ring groups, call queues, and spam prevention. This makes Zoom one of the most cost-effective solutions for efficiently managing inbound calls – these features will ensure that your communication workflow is well-organized and running smoothly.

As for the actual app, Zoom is notorious for its easy-to-use interfaces. With high ratings across the App Store and the Play Store, there’s a good reason why Zoom is near the top of this list.

However, unlike advanced softphones like 8×8, the app doesn’t offer advanced calling features like predict dialing, custom call lists, and autodialer. Its security profile lags far behind its competition, with Zoom missing out key features like multi-factor authentication, user permissions, and strict password rules. This makes the app unsuitable for businesses handling sensitive business data, like those in healthcare.

Zoom doesn’t offer any onboarding support either, which may be a drawback for users getting started with the software for the first time.

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.

What's new for Zoom Phone?

January 2024: Microsoft Teams users can now add Zoom Phone numbers to the platform, and those using the Zoom Phone and Microsoft Teams integration can also remain logged into the app for a week, even if their device is shut down.

December 2023: Zoom says in its December release notes that now, “account owners and administrators can include phone numbers in Microsoft Teams Call queues, Auto Receptionists, and Common Areas devices”.

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

4. Vonage

  • Excellent training features
  • Price from: $13.99 per user, per month

Vonage is another quality VoIP system with a solid list of features, including call barge, voicemail to text, spam prevention, and the ability to expand user limits. These capabilities make Vonage almost as scalable as industry leaders like RingCentral and 8×8, which is why our researchers decided it’s a great option for businesses with evolving needs.

Our testers also found Vonage to be the best software for onboarding new employees, and it stands out more generally for staff training features thanks to well-crafted tools for handling inbound calls, from call transcripts to call recording. This excellent selection helped Vonage to a 4.4/5 score for overall features, the third highest out of the 12 VoIP providers we tested.

Try Vonage

Vonage features

Retailers will find Vonage useful: upskilling employees is important for retail businesses, which often have lower-skilled workforces, some of which will be young or working part-time. Plus, retail teams deal with a higher-than-average number of inbound calls when compared to other industries, so Vonage’s wealth of features for dealing with incoming customer calls will be incredibly useful.

Vonage offers great communication features, including video chat options and unlimited SMS messages. Vonage is also another good candidate for switchers, since it allows a fast-scaling business to thrive once it has outgrown its previous softphone provider.

One area that Vonage falls short, however, is in reporting and analytics. The softphone app doesn’t offer advanced analytics in any of its packages, making it less useful than apps like RingCentral and 8×8 for businesses keen on using metrics to monitor their call performance.

Learn more about the app’s capabilities in our Vonage review.

Vonage pricing

Vonage offers three plans: Mobile, Premium, and Advanced.

  • Vonage Mobile($13.99 per user, per month) Vonage’s entry-level plan includes core functionality like unlimited domestic calls, voicemail, spam prevention, call queue, caller ID, video calls, SMS messaging, transcripts, recording, and analytics. Mobile doesn’t include video options or integrations though, making it a poor choice for businesses looking for an all-in-one communication platform.
  • Vonage Premium – ($20.99 per user, per month) This plan adds custom greetings, a virtual receptionist, unlimited meetings for up to 100 people, CRM integrations, and ring groups. Currently Vonage’s most popular plan, Premium is a safe option for businesses looking for a versatile inbound and outbound communication tool
  • Vonage Advanced($27.99 per month) Vonage Advanced comes with everything in Premium with additional on-demand call recording, visual voicemail, and call group features, making it ideal for larger businesses with advanced calling needs.

Who should use Vonage?

  • Retail and sales businesses
  • Remote teams after a one-size-fits-all communication platform
  • Businesses in need of a low-cost entry-level plan

Who shouldn’t use Vonage?

  • Growing businesses that require advanced analytics
  • Businesses that want advanced security features like multi-factor authentication and strict password rules

5. Counterpath Bria Teams

  • Best for collaboration tools
  • Price: $4.95 per user, per month

Counterpath Bria Teams is a carrier-grade SIP softphone application for Windows, Mac, and iOS/Android devices. It includes a range of features specifically designed for business users, and can be deployed within an enterprise environment.

Counterpath Bria is also the most affordable service on this list – even if you opt for the higher tier plan, which includes web conferencing.

Counterpath Bria Teams features

Naturally, Counterpath Bria’s tiny price tag comes with some trade-offs. While it offers a suite of basic features including team messaging, meeting recording, transfer and forward functionality, and HD voice and video calls, it’s missing a number of advanced capabilities.

Notably, it lacks sophisticated calling features like call barge, call monitoring, and customizable call routing, ruling it out from being used by mid-sized businesses handling large call volumes.

However,if you’re working with a tight budget and want a unified communications platform that eliminates the need to switch between different apps or tools, you can’t do much better than Counterpath Bria Teams. With one of its higher-tier plans, you’ll be able to consolidate all of your communication channels in one accessible platform.

If the standard offering doesn’t quite live up to your initial expectations, this softphone application can also be customized with several add-ons, such as screen share or contact management. This gives businesses willing to spend a few extra a useful way to boost their functionality.

6. Zoiper 5 PRO

  • Best for businesses handling sensitive data
  • Price: $49.95 one-time cost

The Zoiper 5 PRO softphone application replaces the now discontinued Zoiper 3, Zoiper Classic, and Zoiper Web apps. It comes as a free version for non-commercial calls on iOS or Android, or businesses can pay a flat rate free of $49.95 for Zoiper 5 PRO – a fully-fledged VoIP packagecomplete with custom branding so you can put your business’s logo and name.

Somewhat surprisingly, Zopier’s security features outperform every other VoIP softphone on this list. The provider offers end-to-end military-grade encryption with standardized TLS, SRTP, and ZRTP protocols, making it an excellent option for businesses handling sensitive internal or customer data.

Upgrading to Zoiper 5 PRO enables functionality on Windows or Mac as well as iOS/Android devices, provides military-grade encryption for added security, and grants access to a unified communications functionality.

We must admit, however, that the interface is a bit outdated, especially compared to more modern solutions like Zoom and RingCentral. What’s more, there are a limited number of CRM integrations available compared to the top providers on our list, and with no API to connect up CRM platforms Zoiper doesn’t integrate with, you’ll be much more limited in your quest to pull all your customer data together around the same platform.

These factors will inevitably be turn-offs for businesses after an ultra-streamlined and intuitive platform but from a security standpoint, it’s still one of the best free softphones you can buy.

GoTo Connect features

GoTo Connect’s team messaging features and intuitive softphone app interface make it easy to connect with your team. This means the software is better suited for rapidly expanding teams than most of the others we tested. To compare, Google Voice, our overall top pick, only scores 2.9/5 for scalability.

Another benefit of choosing GoTo Connect is the vast array of integrations it comes with. Salesforce, Slack, Google Workplace, and Windows 365 are all supported, as well as GoTo Meeting and other apps in the GoTo brand family. This makes it a good option for teams that contain remote workers, who will benefit from a communications solution that doesn’t require a complex, multi-step setup process and is ready to slot in seamlessly alongside other software tools already in use.

GoTo Connect pricing

GoTo Connect offers two pricing plans: Basic and Standard.

  • GoTo Basic – ($27 per user, per month) GoTo’s entry-level plan offers basic call features like number porting, smart call routing, and call forwarding. Lots of call features like ring groups and customizable dial plans are limited, however, capping its use and making it unsuitable for businesses that require more advanced functions.
  • GoTo Standard – ($32 per user, per month) This tier lets you make calls to 50+ countries for free, and also offers advanced features like call recording and real-time analytics, making it ideal for mid-sized international organizations.

What's new for GoTo Connect?

December 2023: GoTo Connect will now let users automate SMS communication to their customers based on aspects of their business workflows.

Who should use GoTo?

  • Remote of fully-remote businesses
  • Businesses already using GoTo business solutions

Line2 features

Line2 represents one of the more affordable options on the list, particularly given everything you get with the plan. Even the higher tier plan is more affordable than half the options on this list, and it offers some serious heft as far as analytics, call quality, and telephone features are concerned. You can even set up a vanity number – an easy-to-remember custom phone number associated with specific words, phrases or numeric patterns.

As part of the Line2 Pro Plan service, the softphone application provides an ideal solution for mobile workers who want to enjoy the full benefits of a VoIP service when they’re away from their desks or are out in the field. However, although Line2 will let you create ring groups and manage a call queue, there aren’t many additional inbound communications features available. If you’re expecting large volumes of inbound calls from customers, we’d recommend a provider like GoTo Connect or RingCentral.

Line2 pricing

Line2 offers one one-price plan, with a discount for yearly billing. Billed monthly, Line2 costs $15.99 per month, though it costs just $13.75 per month when billed annually. Either way, you’ll get access to unlimited SMS and calls within the US and Canada, call blocking, call screening, voicemail transcriptions and recordings, call forwarding, and caller ID.

  • Businesses looking to keep costs low
  • Businesses that want to set up a vanity number

Who shouldn’t use Line2?

  • Businesses that need advanced inbound communication features
  • Growing businesses that require a scalable solution

9. 3CX Softphone

  • Best for Windows 365 users
  • Price from: $175 per 10 users, per year

3CX integrates with Windows 365 seamlessly, and the entire app can be set up in just a few clicks, which is always great for beginners. However, if you’re working with any operating system other than Windows, feel free to move along. The pricing is the unique part of 3CX. It’s free for the first year, which is obviously attractive, but it’s not without its caveats.

The functionality is certainly a bit limited when compared with the other available options like RingCentral and 8×8, and the interface leaves a lot to be desired in terms of staying on the modern style. Still, for the price, it’s a solid enough option to meet the needs of many small businesses.

  • 3CX Enterprise (From $180 per year per 10 users). The provider’s advances tier adds custom phone logos, Microsoft Teams, skill-based routing, and start/stop call recording, but its price is determined on a case-by-case basis.

The service also offers a permanent free plan with live chat, team messaging, WhatsApp, video conferencing features, and more. For a complimentary plan, its offering is quite impressive. But if you’re a business user that requires slightly more advanced capabilities like desk phone support and call reporting, it will fall short.

How We Research VoIP Software and Softphone Apps

Tech.co’s in-house research team compared all of the top VoIP software providers against each other. To do this, we broke down all of the core categories that matter most to consumers. We settled on seven main areas of investigation:

  • Price What is the overall cost to the business, given the price and the value offered?
  • Features What can the platform do?
  • External connections Does the platform integrate with any existing communication infrastructure?
  • Customer support How does the provider offer assistance should something goes wrong?
  • Security How secure is your data on the platform?
  • Scalability Can the software keep up with a fast-growing company?
  • Customer score How have other users rated the platform?

Once each provider was tested and researched, we gave them a 5-star rating for each area listed above, as well as an overall 5-star rating that factored in all seven research categories. In the end, RingCentral took the lead, with 8×8 and Vonage close behind.

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.

Verdict: What Is the Best Softphone App?

RingCentral Office is the best softphone app for businesses on the market today because it has a robust feature catalog, high scalability, and vast set of possible integrations, which means it will work well with your existing software.

You’ve made it this far, which means you’re definitely in need of a softphone app to improve communication at your business. RingCentral isn’t the only worthwhile option.
