Best VoIP provider of 2024

The best VoIP providers make it simple and easy to set up an internet-based software phone system that supports both office use and remote working.

VoIP (Voice over Internet Protocol) has become an integral feature for modern business communications, and is replacing the familiar landline. The reasons are simple: VoIP is easy to set up for office, remote working, and mobile device use; VoIP can deliver on productivity integrations and analytics; and even better is that VoIP has all features of an advanced PBX phone system but at a fraction of the cost.

RingCentral MVP- formerly known as RingCentral Office - is a great all-rounder for businesses, regardless of industry. It's a cloud-based PBX platform that includes all the features that modern organizations have come to expect from their VoIP system: video software, collaboration tools, and even AI capabilities.

All the core features are included, such as an auto-attendant system, a company directory, call forwarding and handling, and multiple extensions. A 99.999% uptime SLA also means that businesses can have peace of mind that any disruptions to their communications network are going to be infrequent affairs.

There is also a range of pricing plans to choose from, starting with the Essentials plan for small to medium-sized businesses, and includes unlimited voice and video calling, a free local and toll-free number, and 1500 toll-free minutes but the limit of 20 users is unlikely to be enough for some firms.

Fortunately, RingCentral’s plans for larger businesses are where the solution really comes into its own. The Standard plan comes with no limits on user numbers, while the Premium offering also comes with automatic call recording, real-time analytics, and integrations with popular CRM tools like Salesforce, Zendesk, and more.

For organizations that need the most advanced VoIP solutions, the Ultimate package, also comes with device status reports and unlimited storage. Whatever plan businesses plump for, the scalability of RingCentral MVP is one of its most important benefits. With APIs available in the backend, this is a VoIP solution that can be scaled and customized accordingly into a full-scale unified communications solution as well as a cloud contact center.

Support can sometimes be lacking

Perhaps the first thing to notice about the 8x8 eXperience Communications Platform is its price tag. For an enterprise-standard VoIP service, its base offering is very affordable, which is ideal for any organization that feels like it is currently spending too much on its communication tools.

The 8x8 Express Plan comes with unlimited video conferencing, chat, calling, and SMS messages across the US and Canada and a bespoke app to manage all your business communications. As a sweetener, the plan also comes with a one-month free trial, plus three months of Wix Unlimited so small businesses can get started with their website building plans as well.

For businesses that need more features than those on offer with the Express plan, the X Series X2 plan provides unlimited calling within 14 countries, video and audio conferencing, SMS, MMS and Teams chat functionality, and various enterprise integrations, including Google Workspace, Microsoft 365, Outlook, NetSuite, Salesforce and ZenDesk.

The X Series X4 plan, meanwhile, adds unlimited calling within 47 countries, call quality reporting, and supervisor analytics. Additional plans are designed to cater for voice-focused contact centers and multichannel associates.

It is worth noting that the 8x8 eXperience Communications Platform does not offer a bargain basement service – and higher-level plans can come at a significant cost. Aside from the great affordability provided by 8x8's more basic plans, all the company's solutions also make great collaboration tools. A universal team messaging application allows businesses to collaborate internally as well as with clients and vendors and includes extensive interoperability with third–party solutions.

Does not include cloud storage

With all of the VoIP solutions featured in this guide, there is a multitude of different features on offer, depending on the particular pricing plan that businesses decide to go for. What makes GoToConnect so impressive is the sheer number of features available, with the platform offering businesses more than 100 calling, collaboration, and mobile features and tools, as well as several video conferencing services.

All of the general features, including custom call routing, team-based call distribution, as well as time-based and geolocation routing, are included, and customers also have access to personal meeting rooms.

Advertising itself as a UCaaS solution, businesses don’t need to install any new equipment and GoToConnect will handle all maintenance and upgrades. That being said, the company does recommend that customers have a business-standard router, an Ethernet switch capable of Quality of Service, and a firewall configured to allow access to HTTP, HTTPS, and UDP traffic on their network.

Interestingly, unlike most VoIP service providers, GoToConnect does not charge businesses more for additional features. Instead, the company’s pricing plan varies based on how many employees a business has. Prices range from $29.95 per user, per month for customers with between one and four users, to as little as $19.95 per user, per month for businesses with between 50 and 99 users. All pricing plans come with access to the majority of GoToConnect’s tools, and bespoke pricing plans are available for businesses with more than 100 members of staff.

Among the available features are Cloud PBX, custom hold music, call management, advanced ring strategies, and one-click screen sharing. Of course, more features do mean a greater potential for things to go wrong, but GoToConnect also offers extensive email and call support should any issues arise.

No 24/7 phone/email support

If you’re considering cloud-based communication for your employees and customers, Nextiva certainly has many points in its favor, including flexible pricing plans and a range of features to match many of its rivals.

You can make unlimited calls to any phone in the US or Canada, and its real-time presence feature also allows you to see which of your contacts is currently available, while the call queue allows you to handle calls during busy times. Video conferencing is available with all plans, and Nextiva allows you to share screens and files during your conferences. You can also use Nextiva’s video function to livestream virtual events and webinars

Other features include that voicemail messages can be delivered directly to your email inbox, and the software also gives you the ability to record your outgoing voicemail message. You can also send and receive an unlimited number of text messages, and you can send and receive unlimited faxes.

Nextiva's system has clearly been designed with usability and functionality in mind. By dividing its tools on the basis of communication, sales, and service, the company allows you to find the features you need as soon as you log in.

There are also various integrations available, such as for Outlook and Google Contacts, as well as for Salesforce, Hubspot, and Zendesk on the Professional plan.

One of the biggest selling points could lie in the option for a free trial. If you’re still undecided, it might be worth signing up for the trial to see if Nextiva is the right solution for your organization.

Less accessible developer platform

Software has changed the nature of telephone communications in many offices and this is particularly evident when using Dialpad. The VoIP solution is cost-effective and well-designed and is particularly suited to businesses that have workflows favorable to using softphones – software applications that are installed on internet-connected devices in order to make phone calls.

The company’s VoIP offering, actually called Dialpad Talk, uses cloud calling and AI to boost employee productivity and flexibility. Members of staff can work from anywhere and use any device for their business conversations, and AI-powered voice intelligence can be used to automating note-taking and detect customer sentiments during a call.

User setup is straightforward as Dialpad comes with one central administrator portal that makes it easy to add new users, assign them phone numbers, connect them with office suites like Google Workspace and Microsoft 365, and establish their permissions. The whole process should only take a few minutes and either a desktop interface or smartphone app can be used to manage user profiles day-to-day.

While remote working has certainly become more common of late, Dialpad remains compatible with many desk-based phones, and the company has also partnered with Jabra and Poly to integrate functionality with a number of headsets.

Price-wise, Dialpad Talk is extremely competitive, and there is an option to include integration with the identity management platform Okta.

Some features still in development

Affordably priced and with a couple of different plans to choose from, Ooma Office is a great choice for smaller firms or businesses that have a sizable number of remote workers. 

The basic plan comes with a mobile app, a virtual receptionist, call-forwarding functionality, and a host of other features. Ooma Office Pro adds video conferencing tools, voicemail transcription, and a number of other useful business features.

The offering is particularly useful for companies with remote workers, with both the mobile and desktop apps allowing workers to make and receive unlimited calls within the US using their business number. 

Another particularly handy feature is Ring Groups, which allows organizations to group extensions together so they all ring simultaneously. The call is then simply transferred to whichever employee answers first. 

Although the fact that video conferencing only comes with the more expensive pro plan may disappoint some businesses, Ooma Office still represents a great choice for firms that may not need the flashiest VoIP solution.

Limited user capacity

Microsoft’s many digital solutions are already commonplace in offices all over the world and the company now has a cloud telephony service to add to its portfolio. Microsoft Teams Phone lets organizations make calls from any device to anywhere in the world, leveraging the company’s cloud services to ensure high levels of reliability and good audio quality.

In terms of pricing, Microsoft Teams Phone works out to be very affordable - particularly if subscribers are already paying for Microsoft 365. It includes a cloud-based phone system with advanced features such as call transfer, multi-level auto attendants, and call queues, as well as 24/7 customer support. 

Perhaps the most attractive feature of Microsoft Teams Phone is the way that it integrates seamlessly with Microsoft Teams. Since the onset of the COVID-19 pandemic, Teams has become increasingly important to businesses and many will no doubt appreciate the ease with which Microsoft Teams Phone connects to the platform. Setup is quick and it is easy to view upcoming Teams meetings and connect to discussions via your VoIP handset. 

The major drawback for users of Microsoft Teams Phone is that it comes with a user limit of 300, which makes the service suitable for small to medium-sized businesses (SMB) only. Nevertheless, if that’s not an issue, then Microsoft Teams Phone represents a great option, particularly for firms that already rely on a number of other Microsoft solutions.

Configuration can be challenging

1-VoIP offers both residential and business VoIP solutions, with its business offering proving particularly useful for companies on a budget. Companies gain access to HD call quality and more than 40 features across 1-VoIP’s metered plan. With this plan, customers only pay for what they use, facing an additional charge of 2 cents per minute for any calls made.

All features are included with each business plan, with extension-to-extension calling, digital call forwarding, and cell phone redirection available at no extra cost. Other useful features include the use of an auto attendant to make sure callers are redirected to the correct department, and custom pre-recorded announcements that can be adapted for each particular recipient. 

One of the most useful aspects of the 1-VoIP solution is its integration with the third-party anti-spam service Nomorobo. So far, this solution has been used by organizations to block more than 2 billion automated spam calls. The service is flexible, allowing companies to toggle the feature on and off, and businesses can report new spam numbers to the service for review. The service is also continuously monitored so calls from essential services like schools and pharmacies are always permitted. 

A few frustrating aspects of the 1-VoIP service have been pointed out by users, particularly in terms of the setup and configuration. Finding the right settings for international calling can be challenging, for example, and there’s not much in the way of integration with CRM solutions. Nevertheless, 1-VoIP is a good choice for businesses that want a fairly standard VoIP solution that will prevent telemarketers from pestering their employees.

Configuration is overly complex

Telecoms giant AT&T may be one of the older players in the communication space but that hasn’t stopped it from adopting the most up-to-date developments in the VoIP market. In particular, what makes AT&T Business so unique is the way that it integrates with legacy systems. AT&T Collaborate supports prebuilt integration with approximately 30 external services, including Microsoft Outlook, Microsoft 365, and various Salesforce offerings, and existing analog office phones can continue to be used.

Although new registrations are no longer being taken for AT&T Collaborate, AT&T Office@Hand is a flexible cloud-based solution delivering voice, fax, and text messaging options, as well as audio and video conferencing features. The solution is cloud-based and comes with three pricing plans.

The Standard Edition includes unlimited internet faxing, 1000 toll-free minutes per month, and allows unlimited user numbers. The Premium Edition also comes with Salesforce integration and 200 HD video seats. Prices for the Enterprise Edition vary but all customers will receive 10,000 toll-free minutes a month.

While AT&T does allow businesses to use their own hardware for the Office@Hand service, providing it is compatible, the company will not be able to provide help desk support. Instructions will be provided on how to configure the equipment but that is unlikely to completely prevent difficulties from arising, so it’s a good idea for businesses to employ experts during the installation process.

Once installation and configuration are out of the way, however, AT&T Business is simplicity personified. Each employee is given their own unique extension and direct-dial number for voice, fax, and text messaging.

Not the most advanced set of features

Acquired by remote access solutions provider LogMeIn in 2018, Grasshopper delivers a great VoIP service for smaller firms, particularly those that may not have the financial resources to invest in additional hardware. With Grasshopper, businesses simply gain access to a PBX software instance that connects extensions to existing phone numbers. Businesses only need a functioning phone number, existing handsets (which includes cell phones), and a reliable internet connection. 

But while the requirements for Grasshopper are slight, the number of features on offer are also somewhat limited. There is no analytics here, nor the kind of advanced features needed to support call centers or VoIP desktop phones. Customers do gain access to an unlimited number of business calls and texts, call forwarding options, and 24/7 support but beyond that, there’s not much to say about the Grasshopper solution.

Fortunately, the pricing is very favorable, with a Solo-tier for one number and three extensions. The Partner tier, on the other hand, offers three numbers and six extensions, whole the Small Business tier comes with up to five numbers and an unlimited number of extensions. Unlike most VoIP providers, Grasshopper’s prices aren’t charged on a per-user basis. These are all-in monthly costs, which means small businesses could face a significantly smaller bill. 

Aside from the price, the ease of setup is another bonus of the Grasshopper solution, with users simply selecting their service level and choosing their numbers before the service is ready to go. There’s also a  desktop, iOS, and Android app for easy management of Grasshopper’s features.

VoIP provider FAQs

Do you need VoIP provider services or VoIP hardware? 

It can be easy to mix up the two when you've just started your search, but answering this question early on will help you find the best VoIP provider for your business faster.

While VoIP hardware refers to the phone handsets themselves, VoIP service providers actually deal with the establishment and routing of calls over a high-speed internet connection.

Many VoIP service providers also provide additional telephony features. Often, these features can transform a standalone business VoIP solution into a unified communications (UC) platform, with functions specifically designed for business communication.

Top VoIP service providers for business 

Some of the best known VoIP service providers include Aircall, Avaya, Vonage, and RingCentral, in addition to well-known tech firms like Microsoft and Google. 

These companies may list their solutions as VoIP services, VoIP business phone systems, or cloud phone systems. Ultimately, these terms all mean using a broadband internet connection to make a voice call instead of a regular (or analog) phone line.

Continues below...

What is VoIP and how does it work?

Let's start with the basics. VoIP, or Voice over Internet Protocol, is a technology that enables voice communications to be transmitted via an internet connection rather than through a traditional phone network. 

VoIP works in much the same way as a conventional phone system, but it’s usually much more affordable and easier to scale.

VoIP technology also comes with a suite of benefits that traditional phone systems don’t. For example, it enables you to make or receive calls from virtually any device, in any location, as long as you have an internet connection. Use your smartphone, tablet, computer, or even dedicated VoIP hardware to stay in touch at all times.

Many VoIP systems also come with several advanced features, such as simple call routing, advanced on-hold messages, and multiple phone numbers.

At the higher end of the spectrum, many VoIP packages are equipped with integrated tools, such as online fax, integrated email marketing, and video conferencing.

The benefits of VoIP

These are some of the most common features offered by VoIP providers. They usually come as standard, although some will only be included in more expensive packages.
