8 Best VoIP Providers for Small Businesses

Best 8 VoIP Providers for 2025

Our in-house experts have conducted user-testing and extensive research into the VoIP industry — examining the top VoIP providers based on their service, value, customer support, and features offered. The reviews below are based on this independent analysis and testing.

1. Zoom US & CA Unlimited – Best Small Business Plan Overall

• Price: $15 per month

Zoom US & CA Unlimited is the best overall VoIP plan for small businesses, based on our extensive research and testing. The platform has no domestic call limit, gives you access to the provider’s AI companion, and offers extensive hardware integrations. What’s more, it boasts excellent security features, so you can rest easy even while conducting business at scale.

What we like about Zoom US & CA Unlimited

Despite Zoom US & CA Unlimited’s small price tag, our research found it offered the most competitive call management toolkit out of any other plan we researched.

From standard VoIP capabilities like call queue and call screening to stand-out tools like shared line appearance and multi-level automated menus, the tier offers just about any call management feature your business may need, whether you regularly make sensitive phone calls, or have complex customer support needs.

During testing, I was particularly enamored with how easy Zoom was to use. With a recognizable and intuitive interface, it’s an absolute dream to navigate. The platform uses space very well, with a full-width navigation row at the top of the page that clearly delineates between calls, calendar view, home, and more.

What are Zoom US & CA Unlimited’s key features?

• Call queuing, which lets you place callers on hold and route them to available agents. Neither Nextiva Core nor Ooma Office Essentials offer this.
• Flexible hardware integrations. The plan lets you connect with desk phones from seven different IP phone manufacturers. Net2Phone Essentials and Ooma Office Essentials only integrate with two hardphone brands.
• Inbound communication features, including instant messaging, SMS messaging, and video conferencing with its native Zoom Video integration.
• 24/7 live chat and phone support, as well as a knowledge base and user forums if you’d prefer to solve your problem independently. However, there is no onboarding support.
• Slightly limited range of integrations, including Salesforce, Outlook, helpdesk software, and of course, its video platform Zoom One.

How much does Zoom US & CA Unlimited cost?

The plan costs $15 per user, per month, and as you can likely guess from the name, provides inclusive outbound calling, so you won’t have to pay too much to make a call.

You can also purchase an add-on that will give you unlimited calls in a further 19 countries, making it a good option for businesses with global customer/client bases. You won’t be able to access this add-on on the Metered plan.

However, if you don’t manage a lot of domestic calls, Zoom also offers a Metered package ($10 per month) which lets you make calls on a pay-as-you-go basis, so you just pay for what you need. If you want to unlock limitless international calls, you can also opt for the Pro Plus plan for $18.33 per user, per month.

You can also purchase Zoom Phone as part of Zoom One, which rolls the provider’s Meetings, Team Chat, Whiteboard, and Zoom Phone products into one single package. You will need to purchase the Business Plus tier ($22.49 per license, per month) or the Enterprise tier (no public pricing – contact sales for a quote) if you’d like Zoom Phone.

Who should use Zoom US & CA Unlimited?

• Smaller teams that manage high call volumes
• Businesses with smaller budgets
• Businesses already using Zoom Video
• Customer service and retail teams

Who shouldn’t use Zoom US & CA Unlimited?

• Sales teams that need advanced outbound call features like predictive and power dialing
• International businesses that regularly make calls overseas
• Businesses looking for onboarding support (Zoom offers none)

2. Dialpad Standard – Best Time-Saving AI Features

• Price: $15 per month, per user

Dialpad Standard is another affordable VoIP plan that’s packed to the brim with useful calling and communication features. At just $15 per user, per month, its price matches Zoom US & CA Unlimited head-to-head. And with some excellent AI-enhanced features in its toolkit, it’s an option well worth considering.

What we like about Dialpad Standard

Dialpad Standard has plenty of useful features for teams receiving frequent inbound calls, such as custom greetings, voicemail, a virtual receptionist, voicemail to text, customizable hold music, ring groups, and company hours.

Unlike rival plans like Ooma Office and Vonage Mobile, the VoIP package automatically transcribes voicemails and calls using AI, before sending them to the user so they can send a copy, and refer back to them in the future.

These smart AI features help businesses to quickly locate specific information in recordings and make Dialpad’s Standard plan particularly useful for businesses handling important data like banks and insurance companies, law firms, and healthcare providers.

What are Dialpad Standard’s key features?

• Wide range of inbound and outbound communications features, including unlimited SMS and MMS messages and built-in team messaging.
• Web and chat support is provided, along with a user forum and knowledge base. Onboarding assistance is also available.
• Excellent AI features, such as real-time transcripts, instant call summaries, voicemail transcription, and real-time analytics and reporting.
• Great security options, including user management, an admin portal, single sign-on, HIPPA/BAA compliance, and locked meeting rooms.

How much does Dialpad Standard cost?

Dialpad’s Standard package costs $15 per user, per month, matching the price of Zoom’s US & CA Unlimited plan eye-to-eye. The plan includes unlimited domestic calling, unlimited AI meetings for up to 10 participants, real-time analytics, and more.

However, if you want to unlock benefits like 24/7 live agent support, CRM integrations, and support for up to 10 office locations, you’ll have to upgrade to Dialpad’s Pro plan for $25 per user, per month.

Who should use Dialpad Standard?

• Businesses that handle sensitive data, like sales teams and professional services
• Businesses that make high volumes of domestic calls
• Startups that are looking to keep overheads low

Who shouldn’t use Dialpad Standard?

• Growing sales teams that require specific CRM integrations
• Businesses that require 24/7 customer support

3. Net2Phone Essentials – Great for Remote and Hybrid Teams

• Price: $19.99 per month

Net2Phone Essentials is a feature-rich VoIP plan that offers unlimited international calling to Mexico and Canada for just $19.99 per user, per month, making it a great value for businesses that regularly make calls to these locations. This plan offers some of the best unified communication features too, making it a safe bet for remote and hybrid teams.

Net2Phone’s prices increase for teams with less than 25 people, however, making it slightly less favorable than Zoom or Dialpad for smaller, budget-conscious businesses.

What we like about Net2Phone Essentials

We found that Net2Phone’s Essentials excels at helping small businesses handle calls, offering the widest selection of call management tools out of any provider we researched behind Zoom Phone.

The plan offers all the staples you’d expect including call forwarding, call recording, ring groups, and customizable call routing. Unlike alternative tiers like Dialpad Standard and Ooma Office, the VoIP plan also offers call queue capabilities – allowing businesses to manage incoming calls when agents are busy.

Beyond that, the plan has a great toolkit for enabling remote and hybrid teams to conduct business and stay connected, with instant message tools and SMS and MMS – a perk that rival plans by Google Voice and Vonage don’t offer. This can be used for internal comms, with user-to-user, department, or company-wide messaging.

What are Net2Phone Essential’s key features?

• Extensive call functionality, including extension-to-extension calling, hold music and messaging, time-based greetings, three-way conferencing calling, group conference calls, easy call transfer, “find me/follow me” call routing, call queuing, and call forwarding, and support for multiple virtual receptionists.
• Voicemail transcription and voicemail-to-email functions.
• Boasts strong analytics, with sortable reports by time frame, department, office, and agents, all viewable via centralized dashboards.
• Net2Phone offers 24/7 support on all its plans, as well as an extensive online knowledge base.

How much does Net2Phone Essentials cost?

Net2Phone’s Essentials package costs $19.99 per user, per month for businesses with 25-99 users. Prices increase for smaller businesses, with the plan costing $21.99 per user, per month for teams of 10-24, and $27.99 per user, per month for teams of 1-9.

The VoIP provider also offers a professional package starting from $24.99 per user, per month, with unlimited international calling, and AI features like call transcriptions and summaries.

Who should use Net2Phone Essentials?

• Businesses that regularly make calls to Canada or Mexico
• Businesses looking to streamline internal communications

Who shouldn’t use Net2Phone Essentials?

• Businesses that make international calls to a variety of countries
• Small businesses looking to keep overheads as low as possible

4. RingCentral Core – Best for Hospitality and Retail Businesses

• Price from: $20 per month

RingCentral serves more than 300,000 businesses for a reason. It’s a great fit for hospitality, retail, healthcare, and customer service teams, thanks to a range of features designed for fielding high volumes of inbound callers.

What we like about RingCentral Core

RingCentral’s Core plan includes unlimited domestic calls, number porting, custom greetings, a virtual receptionist, spam prevention, voicemail-to-text, caller ID, call transcripts, and custom call routing.

The plan also lets you transcribe calls and voicemails using AI, giving it a leg-up over Net2Phone Essentials for businesses that are looking to move away from manual transcription.

What are RingCentral Core’s key features?

• Video conferencing is available for up to 100 participants.
• Great collaboration features like a task manager, online whiteboard, team messaging, and document sharing.
• Integrates with Google Workspace and Microsoft Teams.
• Excellent security features, such as multi-factor authentication (MFA) options for end-users, and extensive compliance certifications.
• RingCentral offers 24/7 phone and live chat support, as well as an extensive FAQs section and training videos that can help you fix your own problems.

How much does RingCentral Core cost?

Overall, RingCentral’s first plan isn’t quite as cheap as Zoom Phone’s $15 per user, per month Unlimited package. However, RingCentral has better collaboration and advanced outbound comms features.

The $25 per user, per month Advanced plan adds automatic call-recording, a Salesforce integration, single sign-on functionality, call queuing, ring groups (which lets multiple phone numbers all ring when one extension is called), call monitoring, call barge, call whisper, and analytics.

You’ll also get access to many more integrations for CRM, email, helpdesk, web conferencing, and both internal and external live chat services.

RingCentral also offers an Advanced and Ultra plan if you’re interested in unlocking extra features. Check out our complete guide to RingCentral pricing for more information.

Who should use RingCentral Core?

• Growing businesses – it’s very scalable
• Businesses that prioritize security
• Businesses looking to get set up quickly

Who shouldn’t use RingCentral Core?

• Businesses with advanced web conferencing requirements
• Businesses on a tight budget with relatively simple calling needs

5. Nextiva Core – Best for Omnichannel Experience

• Price: $15 per month

Nextiva has a straightforward interface and enough inbound call tools to satisfy a small or medium-sized business. The provider has recently pivoted to a full omni-channel customer experience platform, making it an asset to retailers and sales teams that utilize ecommerce and social media channels.

Its starter package, Nextiva Core, will also be a great choice for small professional service businesses due to its powerful client communication and team collaboration tools.

What we like about Nextiva Core

Truth be told, Nextiva is much more than VoIP solution. Acting more like an omnichannel communications platform, Nextiva Core gives businesses multiple ways to manage customer interactions, including by email, live-chat platforms, SMS, and social media channels like LinkedIn, TikTok, Instagram, and more.

Even if Nexiva Core lacks a feature you need, you’ll probably be able to make it up using one of its many third-party integrations. The plan outshone rivals in our research, by offering the widest selection of external add-ons, from CRM, helpdesk, customer-service live chat options, and beyond.

This army of integrations makes the package extremely flexible, and positions it well for fast-growing businesses whose needs are constantly evolving.

What are Nextiva Core’s key features?

• Nextiva Core offers 24/7 unlimited customer support via phone or live chat. Email support is available, although it is not 24/7. The service also has a large help center to help you fix problems yourself.
• Nextiva’s desktop app supports voice and video calls, emails, messaging, and sales and service tools, as well as analytics.
• There’s a suite of AI and automation tools that can help improve repetitive tasks such as data collection, and offer real-time predictions and suggestions of what to do based on how your team is performing.

How much does Nextiva Core cost?

Nextiva Core costs $15 per user, per month, and gives users access to unlimited inbound & outbound voice calls, video meetings, business SMS messages, and integrations to social media and messaging apps.

Nextiva also offers two prier packages with more advanced reporting and CRM features, Engage ($25 per month) and Power Suite CX ($75 per month). The provider’s prices are are slightly higher than others on this list, but if you’d benefit from its omnichannel channel features, it’s plans would easily pay for themselves overtime.

Who should use Nextiva Core?

• Sales teams and professional service businesses
• Businesses with high call volumes

Who shouldn’t use Nextiva Core?

• Businesses that regularly onboard new staff
• Businesses with very small budgets

6. Vonage Mobile – Best Staff Training Features

• Price: $13.99 per user, per month

Vonage is a versatile VoIP provider that offers a range of different scalable packages for small businesses. Its Mobile package can handle high call volumes, and offers a range of useful call management and training tools, all for just $13.99 per user, per month.

The entry-level plan works great through mobile devices and desktops, making it one of the most flexible options for small businesses. However, if you want to integrate Vonage’s software with desk phones, you’ll have to upgrade to one of the provider’s pricier plans instead.

What we like about Vonage Mobile

Like all the platforms on this list, Vonage Mobile offers a great selection of features for managing inbound and outbound calls, including a neat bandwidth saver that lets businesses maintain strong call quality even with a poor internet connection.

But what really sets it apart is its unrivaled set of features for training staff. You’ll be able to listen in on calls and join existing calls between users and customers/clients. For sales teams, ensuring your on-call manner is constantly improving is super important.

What are Vonage Mobile’s key features?

• Wide selection of features for managing incoming calls, including an admin portal, voice mail, spam prevention, voicemail to text, call queue, caller ID, call forwarding, call “flipping,” and more.
• Outbound features include external video calling, SMS support, custom call lists, internet fax, and call conferencing.
• Available integrations include Microsoft Dynamics, Microsoft Teams, Google Workspace, Office 365, Slack.
• Vonage Phone offers phone and email support but no live chat. In addition, none of it is available 24/7.

How much does Vonage Mobile cost?

Vonage’s cheapest plan, Mobile, gives you unlimited calls and SMS messages, plus all the features listed above and access to the Vonage app center. Right now, there’s a 12-month promotion running that makes the first plan just $13.99 per user, per month, helping it to undercut the price of all the other VoIP plans on this list.

See how the rest of Vonage’s plans compare in our comparison table below:

Who should use Vonage Mobile?

• Customer service teams, who will appreciate the training features
• Businesses that onboard regularly, and want lots of help

Who shouldn’t use Vonage Mobile?

• Businesses that don’t want to rely on add-ons
• Businesses with advanced video conferencing needs

7. Google Voice Premier – Best for Google Workspace Users

• Price from: $30 per month

Google’s VoIP service stands out for one big reason – great security. This is due to its myriad of compliance certifications, multi-factor authentication, single sign-on, password rules, best-in-class encryption, and user permissions on every plan. Its Premier plan offers its full suite of VoIP features, including unlimited domestic and international location support.

However, the plan isn’t as capable of managing high call volumes, and it barely offers any third-party integrations, which is why we weren’t able to place Premier higher on this list.

What we like about Google Voice Premier

During our latest round of user testing, I took Google Voice for a spin, and as you would expect from a product in the Google suite, I can confirm that it’s a joy to use. The interface is clearly and logically mapped out, and I was able to navigate the platform with ease.

If you’re already accustomed to using Google products, even better. Voice has all the small “moments of delight” that you’ll find elsewhere in the Google Workspace, including a cute selection of images that you can assign as profile pictures. You can even edit these images, if you like.

All Google Voice plans to offer voicemail support, voicemail to text, spam prevention, video calling (via Google Meet), SMS for those in the US, analytics, and custom call lists (via Google Contacts).

In terms of the VoIP fundamentals, Google is a little lacking compared to other providers on this list. There are no call queues, custom hold music, caller ID, auto or predictive dialing, call conferencing, call forwarding, call flip, call barge-in, or call whisper. Calls can’t be monitored, and there’s no call-flow designer.

But for existing Google devotees who just want a simple, no-frills platform that’s easy to use, you won’t find a better option than Voice.

What are Google Voice Premier’s key features?

• Excellent security tools, including MFA options, password rules, and data storage in Google’s world-renowned data centers.
• Seamless integration with other products in the Google Workspace. However, lacks many third-party integrations.
• Help and support options include access to a user forum, knowledge base, and 24/7 phone support, but no email or live chat options.

How much does Google Voice Premier cost?

Google’s Premier currently costs $30 per user, per month, making its price point quite a lot steeper than other plans on this list – especially Zoom US & CA Unlimited and Dialpad Standard.

However, unlike these competing plans, Google’s Premier package gives you access to perks like advanced reporting, and support for unlimited domestic and international locations, helping to justify its slightly higher price point.

Google also offers Starter and Standard plans with slightly more stringent user limits, costing $10 per user, per month, and $20 per user, per month respectively.

Who should use Google Business Premier?

• Businesses that already use Google Workspace
• Businesses that manage highly-sensitive data

Who shouldn’t use Google Business Premier?

• Businesses with advanced call requirements
• Sales businesses and teams that manage high call volumes

8. Ooma Office Essentials – Great for Customer Support Features

• Price: $19.95 per month

Ooma Office offers a particularly good customer experience and generally gains high customer satisfaction ratings from existing users. It’s entry-level Essentials plans offers 24/7 customer support over the phone or via live chat, although not over email. It also offers an online forum, where experienced users can help you diagnose and fix problems yourself.

What we like about Ooma Office Essentials

Our researchers were unanimous that the platform was easy to use, with one observing that it was particularly easy to connect with their Google Calendar, and another commenting that answering calls was simple thanks to the clearly laid out interface.

However, some pointed out an issue that arose from the Google Calendar integration. Namely, the Meetings tab features both “Join” and “Meet” buttons, which route users to either Ooma’s native video calling or Google Meet, respectively. It might take users a couple of false starts to ascertain which call-to-action (CTA) directs users to which platform.

Ooma Office Essential’s security protocols really disappointed us in our testing, too. The service doesn’t display its compliance certificates so it’s unsure how strictly they comply with data security standards. Therefore, if your business handles sensitive data, we’d recommend Google Business Premier or Zoom US & CA  Unlimited as they both offer much more advanced security protocols than Ooma.

It also offers a mobile app for Android and iOS, which can be helpful if your teams are working from home without a full desk phone. Despite its selling points, the service does lack some features that other VoIP providers on this list offer, however. For example, no Ooma plans include custom call lists, auto or predictive dialing, call transcripts, call monitoring, or task management. In other words, it won’t be great for sales teams.

However, the platform does boast excellent customer support, only missing out on top marks due to a lack of email support. All in all, only RingCentral scored higher for customer support.

What are Ooma Office Essential’s key features?

• Integrates with CRM platforms including Salesforce, Microsoft Dynamics, Zendesk, Microsoft 365, G-Suite, and ServiceNow.
• Inbound and outbound features include virtual receptionist, virtual fax, ring groups, call park, hold music, transfer music, virtual extensions, and more.
• Help and support options include 24/7 live chat and phone support, as well as a comprehensive knowledge base for solving problems yourself and email support, although it is not 24/7.
• Compatible with native and third-party deskphones, including Yealink, Mitel, Polycom, and Grandstream models.

Who should use Ooma Office Essentials?

• Customer service and retail businesses fielding lots of inbound calls
• Remote or hybrid businesses

Who shouldn’t use Ooma Office Essentials?

• Organizations handling highly sensitive data about their customers and clients
• Businesses looking to create custom call lists

How to Choose the Best VoIP Provider

Choosing the right VoIP provider depends on several factors.

Overall costs

While many VoIP providers seem to offer similar pricing structures, each provider has little quirks in its pricing system which you might miss at first glance.

For example, most providers, including our top-rated picks RingCentral and 8×8, offer prices on a per user, per month basis. You also won’t get as many features on the cheapest plans as you do with the more expensive plans

It’s also worth pricing up the systems you’re looking at in full before choosing. There might be hidden costs with international call fees, for example. The easiest way to get a complete price is by using our comparison tool, which will give you bespoke quotes from the leading companies.

You can also check out our guide to the cheapest VoIP providers to discover the best cost-effective solutions available to your business.

Upgrade and growth costs

Your business isn’t standing still, and you’ll (hopefully) need to start adding new team members as it grows. Again, you need to think here about which platforms will scale the best with your existing business. What’s more, you’ll likely need to add more complex features.

RingCentral is a good fit for businesses that will need to expand their feature set as they grow, as its four pricing plans each offer many core features in comparison to similar competitor plans. Our researchers termed this “scalability,” and ranked RingCentral and 8×8 in joint first place for the most scalable, with Vonage close on their heels.

Customer support

If your business relies on its phones, any problem could be catastrophic to your bottom line.

Fortunately, most of the providers we’ve listed offer 24/7 support. RingCentral and 8×8 scored highest for support options overall (5/5) across all the VoIP providers we tested, while three more services tied for second place (4.5/5): Dialpad, Ooma, and Nextiva.

We would always recommend choosing a provider which offers 24/7 support where possible.

Devices

It is worth considering what sort of hardware your business currently uses for its phone calls. If you rely on desk phones, you might find that your service isn’t as flexible as it would be if you used software-only services.

Softphones, or even VoIP services that work through laptops or tablets, are a great way to help your staff remain mobile while working.

You might also have existing analog desk phones and might be worried about whether they’ll work with your new VoIP system. You can get adapters that will let them connect with your new system, but it’s unlikely to be perfect. Instead, you can take a look at some new VoIP phones, or your provider might even lease you some.
