Let’s dive into more must-know details about each of these VoIP services.

1. OpenPhone

Best VoIP service: OpenPhone

OpenPhone is a business VoIP service that helps you work more efficiently, no matter the size of your team. It’s packed with automation features, including texting auto-replies and IVR functionality that allows for automatic VoIP call routing when clients dial your number. You can also integrate your favorite business apps — including Slack, Gmail, Zapier, and (with an upgrade) a handful of CRMs — to get added context without jumping between platforms.

How to get a business VoIP number with OpenPhone

get a VoIP business phone number with OpenPhone

Getting a new VoIP phone number from almost anywhere in the world is a simple process when you choose OpenPhone as your VoIP phone number provider. Follow these three steps:

  1. Create an account with OpenPhone (when you sign up, you get a free, seven-day trial).
  2. During signup, choose your city or area code in the US to select your preferred phone number.
  3. Once the signup process is complete, you’re all set to use your new virtual phone number!

OpenPhone can also help you scale your business across international markets. Every plan includes free calls and texts in the US and Canada and affordable rates for international calls. Additionally, one US, Canadian, or toll-free number comes free with each user on your team.

Alternatively, unlimited users can share phone numbers to collaborate on calls and texts and split responsibility for incoming communication. This also makes reviewing conversations and coaching your team much easier for managers than other business phone solutions. 

Free phone number porting is also supported if you want to keep your number while switching to OpenPhone.

Need more reasons to call OpenPhone the best VoIP service around? Call recording, voicemail transcriptions, business hour settings, and other essential features all come standard with every plan. Plus, you can access OpenPhone from any device using the desktop, web, or mobile apps.

Key features

  • Free calling and texting in the US and Canada
  • Text message automations (including scheduled messaging, snippets, and auto-replies)
  • Business app integrations (including Slack, Zapier, and email)
  • IVR (auto-attendant)
  • Shared phone numbers
  • Voicemail transcriptions
  • Call recording


  • Starter: $15 per user per month
  • Business: $23 per user per month
  • Enterprise: Contact for custom pricing

2. RingCentral

Best VoIP service: RingCentral

RingCentral is a well-known VoIP provider that paved the way for many modern, cloud-based phone systems. Its basic plan doesn’t offer much more than voicemail transcriptions, SMS functionality, and unlimited calls in the US and Canada. You’ll need to upgrade to access more attractive features like audio and video conferencing, as well as local phone numbers in over 100 countries.

RingCentral also has a few key caveats to keep in mind. If you send a lot of text messages, you can only send up to 25 text messages per user per month before RingCentral charges you extra (or you can upgrade and pay more per month). Additionally, RingCentral stores up to 5,000 text messages per user, making it an unreliable way to store all your conversations.

RingCentral does pretty well in the integrations department, but you’ll need a relatively high-cost Standard plan just to connect to platforms like Slack and Microsoft Teams. More powerful CRM integrations cost a premium — even if you’re not planning on using the open Application Programming Interface (API) or advanced call handling functionality offered within the plan.

Key features

  • Free unlimited calling in the US and Canada
  • Video conferencing
  • Allotted toll-free minutes
  • Business app integrations (upgrade required)


  • Essentials: $19.99 per user per month (max 20 users)
  • Standard: $27.99 per user per month
  • Premium: $34.99 per user per month
  • Ultimate: $49.99 per user per month

3. Ooma

Best VoIP service: Ooma

Ooma is a VoIP service provider offering a small business phone system that can make your incoming call management more efficient. They provide a virtual receptionist that routes callers to the right agent. Plus, ring group functionality sends incoming calls to multiple phone lines until one agent answers.

With every plan, you can get unlimited calling in the US, Canada, Mexico, and Puerto Rico. However, Ooma’s standard plan only allows you to make and receive calls with compatible desk phones or Ooma’s Android or iPhone app. You have to upgrade using Ooma if you want the convenience of a desktop app, which lets you easily navigate to your VoIP phone system while you’re working on your computer.

Upgrading can also unlock key features like voicemail transcriptions and call recording, though other providers offer these as standard features.

Key features

  • Free unlimited calling in the US, Canada, Mexico, and Puerto Rico
  • Ring groups
  • Voicemail transcriptions (upgrade required)
  • Call recording (upgrade required)


  • Ooma Office Essentials: $19.95 per user per month
  • Ooma Office Pro: $24.95 per user per month
  • Ooma Office Pro Plus: $29.95 per user per month

4. Nextiva

Best VoIP service: Nextiva

Nextiva is a popular business VoIP provider used by large-scale enterprises. When you sign up for Nextiva, you can make and receive phone calls, video calls, and team chat messages from a single app on your computer or mobile device.

Nextiva offers a handful of helpful integrations, like HubSpot and Zendesk, with a Professional plan. However, you’ll still miss out on integrating popular apps like Slack and Zapier, which have become essential for many teams.

Although Nextiva can be effective for voice and video calls, this isn’t the best VoIP phone for companies that frequently text clients. You need a Professional plan just to get VoIP texting capabilities. Even with that upgrade, you can only send up to 1,000 messages per user per month, a limit your sales and support reps may quickly reach if they’re helping clients throughout the day.

Key features

  • Free unlimited calling in the US, Canada, and Puerto Rico
  • Video meetings
  • Internet fax
  • CRM integrations (upgrade required)


The price per user with Nextiva varies based on the size of your team. For teams of 1-4 users:

  • Essential: Starts at $23.95 per user per month 
  • Professional: Starts at $27.95 per user per month 
  • Enterprise: Starts at $37.95 per user per month

5. Grasshopper

Best VoIP service: Grasshopper

Grasshopper is a VoIP solution designed for solopreneurs and small businesses. Grasshopper offers all of its key phone features with every pricing plan, though you’ll need to pay for add-ons to get features like simultaneous ring. Other upgrades simply give you access to more phone numbers and extensions — or you can pay $10 per month extra for each additional phone number you want.

Even with add-ons, Grasshopper still doesn’t offer nearly as many features as other providers. The Grasshopper app lacks integrations and automations, so you can’t streamline your business communications to support more clients.

Grasshopper may be one of the best small business VoIP services, but when your company scales, you’ll eventually outgrow what Grasshopper is able to support. Since your pricing plan only determines how many phone numbers and extensions you have, you can’t get access to more features by upgrading your plan.

Key features

  • Free unlimited calling and texting in the US and Canada
  • Voicemail transcriptions
  • Auto-replies
  • Call transfers


  • Solo: $28 per month (one phone number and three extensions)
  • Partner: $46 per month (three phone numbers and six extensions)
  • Small Business: $80 per month (five phone numbers and unlimited extensions)

6. Dialpad

Best VoIP service: Dialpad

Dialpad is a business VoIP provider that offers unlimited video meetings, as well as unlimited VoIP calling and texting in the US and Canada. It’s best known for offering built-in artificial intelligence (AI) features for call centers. This includes real-time call transcriptions, automated post-call summaries, and speed coaching, which tells you if you’re going too fast or too slow. 

However, Dialpad has less-than-ideal phone number options for users. You need to pay $15 to $17 per month for each toll-free number, and you can only port in one number for free. With a standard plan, you’re limited to one phone number per user and can’t even send international texts.

Key features

  • Free unlimited calling and texting in the US and Canada
  • Unlimited video meetings
  • Speed coaching
  • Voicemail and call transcriptions


  • Standard: $15 per user per month
  • Pro: $25 per user per month (three-user minimum)
  • Enterprise: Contact for pricing

7. 8×8


8×8 is a contact center solution that supports unlimited calling in the US and Canada, team messaging, and basic auto-attendants with every plan. With upgraded plans, you can make unlimited international calls to more countries and unlock interactive video conferencing and live streaming features.

If your business does a lot of conference calls, webinars, and sales demos, 8×8 could be the best VoIP provider for your team. However, it lacks texting and calling features most companies need. You won’t even get MMS or SMS messaging until you upgrade.

Key features

  • Free unlimited calling in the US and Canada
  • Multi-level auto-attendants  
  • Team messaging
  • SMS, MMS, and team chat (upgrade required)
  • Voicemail transcriptions
  • Supervisor analytics (upgrade required)


  • x2: $24 per user per month
  • x4: $44 per user per month

8. Vonage


Vonage is a unified communications platform that brings your voice calls, video calls, and messaging all onto one cell phone or desktop app. If your team relies on phone calls to do business, however, you’ll need to pay for one of their upgraded plans to access features like auto-attendant and call recording.

Vonage doesn’t offer a lot of built-in features, but it does support a handful of integrations with third-party apps. You’ll need to pay extra monthly fees for most, on top of upgrading your plan to access CRM integrations like Salesforce.

Key features

  • Free unlimited calling in the US and Canada
  • CRM integrations (upgrade and monthly fees usually required)
  • Auto-attendants (upgrade required)
  • Call recording (upgrade required)


Like Nextiva, Vonage’s price depends on the number of users on your account. For teams of 1-4 users: 

  • Mobile: Starts at $19.99 per line per month
  • Premium: Starts at $29.99 per line per month
  • Advanced: Starts at $39.99 per line per month

9. magicJack


magicJack started as a popular infomercial product, but its newer magicJack for Business offering is a business VoIP solution that lets you make unlimited calls in the US and Canada. Using its desktop, iOS, or Android VoIP app, you can get a second phone number that supports call forwarding and extensions.

However, magicJack for Business requires a lot of add-on costs. Auto-attendant, virtual fax, and toll-free numbers all increase your monthly fees — and even phone number porting costs $19.95.

While magicJack can be the best VoIP service for teams that simply need a business phone number to make calls with, text messaging is only available on their mobile app.

Key features

  • Free unlimited calling in the US and Canada
  • Call forwarding
  • Call transfers 
  • 3-way calling
  • Auto-attendants (monthly fee required)


  • $15.99 per line per month

10. Aircall


If you’re looking to build a remote call center, Aircall is one of the best VoIP services you can find. It offers many features large-scale contact centers need, like call recording and the ability to make more than one call at a time. With more advanced plans, managers can also monitor calls and get more in-depth analytics.

Aircall does charge heftier subscription fees than most VoIP providers. Companies that don’t need a full-blown call center for their business will end up paying a premium for features they don’t need.

Key features

  • Free unlimited calling in the US and Canada
  • Call recording
  • Integrations and API
  • Call monitoring (upgrade required)


  • Essentials: $30 per user per month (three-user minimum)
  • Professional: $50 per user per month (three-user minimum)
  • Custom: Contact for pricing (10-user minimum)

How to choose a VoIP service

When you’re shopping for a VoIP phone service, it’s important to look for a provider that offers all the features your business needs to communicate effectively and efficiently with clients. A few valuable features you can look for include:

  • Mobile, web, and desktop apps
  • Voicemail transcriptions
  • Call recording
  • IVR or auto-attendant
  • Integrations with other tools you already use

A scalable VoIP phone software system will also help you avoid the hassle of a transition as your business grows. Look for a provider that offers more comprehensive plans than the one you currently need — ideally, including a customizable enterprise plan — so you can continue adding more features when the need arises.

Additionally, take into consideration how reliable a VoIP service is as you research and try out new platforms. The best VoIP services should offer strong call quality, consistent uptime, and efficient customer support when you need it most.

How does VoIP work?

How VoIP works
When you make a call on a VoIP phone, your VoIP service converts your voice messages into digital data. In less than a second, this data is broken up into smaller pieces (called “packets”), which are then sent over the internet and pieced back together upon reaching their destination. All your customers will hear is your voice, and vice versa.
VoIP calls don’t depend on physical wiring or circuits, unlike traditional landline calls. As long as you have a strong internet connection, you can make crystal-clear calls without depending on a specific piece of hardware.

How much do VoIP services cost?

VoIP services typically cost between $10 to $40 per user per month. Pricing plans on the higher end tend to offer more customizable solutions that are fit for bigger teams.
Depending on your provider, VoIP subscription costs don’t always include the cost of minutes, extensions, extra phone numbers, and other add-ons.

Are VoIP services worth it for a small business?

VoIP services are well worth the cost for small businesses. You’ll typically get more valuable features — like integrations and automations — for a lower cost than traditional phones. You don’t have to purchase brand-new hardware every time you need a system update. Plus, you can easily access more advanced features or bring new team members on board. VoIP technology can also enable your team to work remotely as these systems are accessible via an internet connection. 
VoIP services handle the technical side of managing a business phone system. If your small business doesn’t have a full-size IT team or the bandwidth for regular troubleshooting, you can benefit from a VoIP service that’ll take care of technical issues on your behalf. 

Are VoIP services secure?

VoIP services can be highly secure if you choose a provider that takes plenty of precautions to keep your data safe. For example, OpenPhone encrypts data and backs it up daily to keep your communications private and secure. Account changes are also logged in case of discrepancies.
Unlike traditional phone systems, VoIP services aren’t susceptible to physical security issues like wiretapping and line cutting.

Can I set up a caller ID for my VoIP service?

Yes, you can still set up caller ID for local phone numbers when you switch to a VoIP service, if you want to let your clients know who’s calling when you reach out. However, keep in mind that caller ID isn’t available for toll-free numbers, no matter what type of phone system you have. Additionally, some Canadian carriers won’t display your caller ID right after setup, since their databases aren’t automatically updated.

If you want more advanced phone features to save time, you need a reliable VoIP solution that supports your business needs.

OpenPhone is the best VoIP service for modern businesses, offering plenty of integrations and automations — along with helpful features like call recording and voicemail transcriptions — for companies that want to work smarter, not harder. Plus, when you sign up, you can test out the platform using a US, Canadian, or toll-free number for free, even if you’re not located in the area.
