We’ve identified the best business phone system providers for businesses of all sizes based on the unique features or calling needs your business might have.
Based on our research, the best business phone systems for businesses ranging in size from solopreneur to small, mid-size, and large enterprises are:
- RingCentral: Best overall, and best choice for businesses looking for advanced calling and communications features, extensive integrations, and a developer-friendly open API
- Nextiva: Great choice for teams in search of video conferencing, calling, texting, and team messaging bundled in a single, easy-to-use interface
- 8×8: Top business phone system for organizations that have an international presence

RingCentral: Best Overall Business Phone System
*Prices calculated using RingCentral’s 33% annual subscription discount and a two- to 20-user estimate.
RingCentral is the leader when it comes to the best small business VoIP services. Its easy-to-use apps are loaded with advanced business calling and communications features like hotdesking, automatic call recording, video conferencing, and real-time analytics. Plus, it has an open API for custom integrations and loads of available third-party integrations.
With an entry-tier cost of $19.99 per user, per month, RingCentral is on the more expensive side compared to virtual phone systems like Grasshopper and Google Voice, but in this case, you get what you pay for. RingCentral’s higher price point rewards business customers with not only a robust suite of calling features but a complete unified communications tool.
On the other hand, setting up a VoIP system could be overkill for smaller companies. Entry-level users sometimes find the vast amount of features a bit overwhelming. Users with more basic needs may be better off starting with a virtual phone system like Grasshopper and scaling to RingCentral when they’re in need of more advanced functionality and higher usage limits.
- Integrations and open API: Connect your entire tech stack and applications to RingCentral using the platform’s open API platform for developers and extensive third-party integration capabilities.
- Advanced call handling: Empower your admins to monitor live calls (call monitoring), whisper helpful tips to agents (call whisper), and take over conversations when necessary (call barge).
- HD audio and video: Whether you’re on the phone or a video call, keep your conversations at top-notch quality with high-definition audio and video.
Nextiva: Best Business Phone System for Unified Communications
*Prices calculated using Nextiva’s annual discount and a five- to 19-user estimate.
Nextiva is the best small business phone system for teams that want a unified communications platform. Your business can do everything from calling, texting, faxing, team messaging, and video conferencing through the platform, and at a lower cost per-user than RingCentral. Plus, Nextiva offers unlimited participants on voice and video conferencing, a perk no other competitor on this list provides.
Nextiva offers similar business calling and communications features to RingCentral and tends to provide advanced features at lower pricing tiers. However, if you’re in need of a more robust set of third-party integrations or custom integrations, you’ll likely still want to choose RingCentral.
While Nextiva’s apps have a dated user interface, they’re still relatively easy to navigate and use. However, users who value ease of use above functionality will find Grasshopper or Zoom Phone to be better options.
- Call pop: Learn important details about your caller and past interactions with them before you even pick up an incoming call.
- Professional greeting: Nextiva includes free professionally recorded voice greetings at the Professional plan or higher.
- Smart automation: Put your relationship building on auto-pilot with welcome emails, intelligent chat bots, and automatic reminders.
8×8: Best Business Phone System for International Calling
*Price calculated using 8×8’s annual subscription discount.
8×8 is the best business phone system for companies calling across borders, and it’s one of the most affordable VoIP services for budget-conscious teams that need more than a virtual phone system. The 8×8 Express plan is a great entry-tier option for small businesses and solopreneurs at just $12 per user, per month.
8×8’s X2 plan includes unlimited calling to 14 countries, and X4 plan subscribers get unlimited calling to 48 countries—something no other competitor on this list comes close to offering. On the downside, users must upgrade to 8×8’s most expensive X4 plan to unlock most countries for unlimited international calling. This can be costly, especially if your business doesn’t need all the other features in that plan.
8×8’s mobile and desktop user interfaces are somewhat dated but exceptionally easy to use. However, the 8×8 mobile app lacks some of the functionality you’ll find on the desktop version, making it a less powerful on-the-go tool. Users planning to rely extensively on mobile apps will have a better experience using RingCentral or Nextiva.
- Team chat: Ditch the messaging apps and email threads in exchange for a more unified, collaborative environment with 8×8’s Team Chat.
- Call center: Upgrade to one of 8×8’s call center solutions to handle any volume of calling and messaging.
- Insights and analytics: Digest real-time, organization-wide reporting and analytics to uncover money-saving insights and improve your customer communications.
Google Voice: Best Business Phone System for Solopreneurs & Freelancers
*Pricing based on Google Voice’s monthly subscription plans.
Google Voice is a virtual phone number service that is best-suited for small businesses and solopreneurs, especially those using Google Workspace apps. Users who start with Google Voice’s free personal plan can get familiar with basic functionality and the user interface, but will need to upgrade to a paid plan to get business calling and call handling features like international locations, auto-attendants, and ring groups.
Unlike the VoIP providers above, Google Voice is a virtual phone system that forwards calls to your device, so you have to have an existing VoIP service, landline phone system, or mobile phone plan in place. It does, however, give small business owners and solopreneurs a second phone number to establish a professional presence and separate business and personal calls, voicemails, and texts.
Business users familiar with Google products will love the familiar look and feel of Google Voice. It integrates smoothly with Google Workspace apps like Gmail, Calendar, and Meet, making it easy to collaborate and keep your work connected.
Google Voice is an entry-level business phone system. While it’s the most affordable option on this list, it’s also the most basic. Businesses with more complex needs that want advanced features like hotdesking, real-time call monitoring, and third-party integrations need to consider systems like RingCentral or Nextiva.
Google Voice Features
- Google Workspace integrations: Google Voice integrates with Gmail, Calendar, Meet, and more to connect data between all your Google applications.
- Ring groups: Notify a group of users for incoming calls to ensure it gets answered quickly.
- Desk phone support: Standard and Premier users can set up compatible desk phones to make and receive calls through the Google Voice platform.
Grasshopper: Best Business Phone System for Simplicity & Affordability
*Pricing based on annual subscription.
Grasshopper is a great option for users looking for a simple, affordable virtual phone system. The desktop and mobile apps are modern and easy to use. However, the user-friendly aspect of Grasshopper mainly comes because the system lacks advanced features like auto-attendants, video conferencing, and team messaging.
When comparing the cost of the best business phone systems, it’s important to note that Grasshopper’s pricing structure is not per-user. For example, Small Business plan subscribers get five phone numbers and unlimited extensions—which effectively makes the price $16 per user, per month (at most, since you aren’t factoring in use of extensions).
Grasshopper’s Instant Response feature lets you text missed callers back automatically. You can let them know your business hours and when to expect a call back, helping you manage call flow regardless of your team’s size. Businesses can also use Grasshopper’s Voice Studio to purchase one or multiple professionally recorded greetings at a flat rate per-session $75 fee.
Unfortunately, Grasshopper doesn’t provide any integrations. If you just need basic calendar and email inbox integrations, Google Voice will be the better option. If you need advanced integrations with customer relationship management (CRM) software or custom applications, consider using Nextiva or RingCentral.
- Instant response: Automatically send a text message to callers when you can’t answer their call.
- Voicemail transcription: Grasshopper automatically transcribes your voicemail messages so you can read and easily cut and paste them to forward to someone on your team.
- Simultaneous call handling: Simultaneous call handling helps you prevent an incoming caller from hearing a busy tone or going to voicemail.
Zoom Phone: Best Business Phone System for Low-call Volumes
*While Zoom Phone has an annual payment option, the pricing doesn’t change significantly. For example, paying monthly for the base plan is $10 per month, and this simply changes the pricing to $120 per year when opting for the annual payment option.
Zoom Phone is a new player to the business phone system space, but they’re playing catch-up quickly with a strong combination of pricing and functionality. Every Zoom Phone plan contains the full features of the platform—except for the Pro plan, which (oddly) doesn’t provide SMS texting.
Zoom Phone comes with powerful features like auto-attendants, interactive voice response (IVR), call handling, call park, team messaging, and team status. Starting at just $10 per user, per month, Zoom Phone is the most affordable way to access some of the industry’s most advanced features. Plus, those familiar with Zoom video conferencing will feel right at home with Zoom Phone’s similar user interface.
On the downside, the platform is still working through minor technical glitches and call quality issues. However, these problems should subside as the software ages and continues to get upgraded. Still, if ease of use and a robust feature set are both important to your business, consider Nextiva.
Zoom Phone Features
- Metered plan: Pay for what you need and nothing more. Pay-as-you-go pricing gives you access to all the advanced features Zoom Phone offers without wasting any of your budget.
- HD call quality: Zoom Phone uses advanced noise cancellation, keyboard typing suppression, and echo cancellation to ensure audio quality is top-notch.
- Elevate to Zoom Meeting: Quickly evolve a phone conversation into a Zoom Meeting or Zoom Room.
