Cheapest VoIP Phone Services of 2025 for Business Use

Why I chose RingCentral

RingCentral has several key attributes that place it at the forefront of this list. For one, RingCentral comes with some of the most impressive features and offerings, right out of the gate (even for Core subscribers). Unlimited domestic calling and AI functionality are available at every tier, and that’s only the beginning.

Many competitors require upgrading to the second or third paid tier for equivalent functionality, making RingCentral a great option for businesses that want all of the bells and whistles on a base plan. While RingCentral may not be as well-suited for teams that need to support international staff or callers, and while some traditional VoIP features require upgraded plans, RingCentral is an excellent fit for smaller teams operating in North America. Additionally, the extensive integrations and artificial intelligence features make it popular for call and contact centers.

Why I chose Zoom Phone

Although this is a list of inexpensive VoIP providers, if I had to pick a leading contender in that category, Zoom Phone would be my choice. With a starting monthly price of just $10 per user, you’re paying less than an ad-free streaming subscription to have a dedicated business phone line. You’re also paying roughly half the starting price for most of Zoom’s VoIP competitors. 

However, Zoom offers more than just phone services. By bundling with your Zoom Workplace subscription, you can add video meeting capabilities, AI companion support, and much more. Some of the more advanced call handling, analytics, and other premium features are harder to find with Zoom, making it less suitable for use cases that involve a lot of complex juggling and shuffling of inbound calls. However, for those looking for reliable service at the lowest price, this is the best choice.

Why I chose Dialpad

Automation and artificial intelligence are two technologies that everyone is seeking these days, and Dialpad delivers as a low-cost platform with numerous features that revolutionize conversational intelligence. And while many providers are new to the game, Dialpad made AI its key differentiator as early as 2018.

Whether you need call transcriptions and post-meeting summaries that replace handwritten meeting notes, or sentiment analysis of customer calls, Dialpad automates the process of multiple everyday tasks. These features, along with automated action items, make it easier for you to collaborate with team members on projects and calls. If you transfer your number from another account, there is also free number porting, which is a win for teams interested in making the switch to a lower-cost VoIP service.

Why I chose Phone.com

Premium offerings tend to come with everything but the kitchen sink. Not because everyone will need every feature, but because, for the price you pay, you expect that all the features you do need will be in the list. More affordable options tend to go the opposite route, stripping out anything unnecessary or outside the niche of the target use case. Phone.com is an interesting example of bridging that gap.

This provider’s feature list isn’t quite as broad or deep as that of some of its competitors. But it isn’t the slimmest either. And it offers incredible flexibility regarding pricing, as you can “mix and match” subscription tiers. That way, each user is signed up according to what features they need, and you only pay higher-tier rates for staff who need them. 

Beyond their pricing structure, Phone.com stands out as the only entry in the list to prioritize above-average privacy compliance. Specifically, they guarantee HIPAA compliance throughout the platform. And while your organization may not be directly involved in healthcare, that’s a higher standard for data privacy than most industries and a win for those who prioritize robust security. 

Why I chose Nextiva

Nextiva is not often the first provider that comes to mind when considering cheap VoIP services, but it is one of the best providers on the market. With a wealth of premium features, a legion of valuable add-ons and upgrades, and an enterprise-focused design, it’s the best fit in this list for larger teams with room in the budget to grow.

Therefore, Nextiva is my top choice for an affordable premium option. While its monthly fees are higher than those of other providers on this list, the annual pricing offers a sufficient discount to make it worthwhile for small business owners. However, smaller teams looking to reduce expenses may find the initial cost frustrating, especially since basic inbound and outbound voice functionality is priced higher. 

Additionally, many of the more desirable features are only available to top-tier subscribers, unlike brands like RingCentral and Zoom, which provide access to these functions at a lower cost. But if top-tier was where you were aiming in the first place, then Nextiva is your best bet.

Why I chose Vonage

Although Vonage is known for its unified communication as a service (UCaaS) provider, its business phone plans still rely on VoIP technology to make calls across the internet. In many ways, VoIP supports UCaaS by providing more affordable phone services, with less money spent on things like hardware and international calling.

In this sense, Vonage provides the best of both worlds, offering the low prices of a traditional VoIP provider along with unified communication features. However, most of these features, such as team messaging and Vonage meetings, are only available on the highest-tier plans. If that’s what you’re looking for, there are other providers, like RingCentral and Phone.com. If you want to pick and choose your VoIP and UCaaS features, then Vonage’s customizable plans and add-on features will be perfect for you.

Why I chose Grasshopper

Not every operation is large and complex enough to warrant a multi-faceted phone system. Sometimes, the team is very small, perhaps even just one person. And sometimes, all you need is a way to separate business calls from personal ones, without having to purchase a separate phone.

Grasshopper provides that, and much more. Its entry-level tier provides nearly all of its functionality, with most of the benefit for upgrading coming in the form of increased user counts and limits. And with lower-than-average costs, and several unique perks and add-ons to help your business sound as professional as possible, there’s plenty to love about Grasshopper’s VoIP services. 

This makes Grasshopper an excellent choice for solo professionals and small teams; however, the lack of video and unified communication features makes it less effective for remote teams that rely heavily on digital tools for collaboration. In that case, you might want to consider Phone.com for its affordable price and video-conferencing features.
