The Best VoIP Phone Systems

According to our detailed research, the following suppliers offer the best VoIP phone systems available in the US for 2024:

1. 8×8

Best All-Round VoIP Provider in the US

What makes 8×8 the best all-around VoIP provider in the US?

Our research has shown that, overall, 8×8 is the best VoIP provider for US businesses. It scored incredibly well in a number of our research categories, including features, security, customer support, and scalability.

In particular, we love the breadth of features available on 8×8’s plans. As you’ll see in our key features analysis below, from the X2 plan upwards, 8×8 boasts all the features we know to be most important for productive comms with customers and clients – from unlimited minutes and local numbers to ring groups, call queues, and CRM integrations. It is also compatible with a range of plug-in-and-play desk phones. 

8×8’s security features also impressed us. With multiple compliance certifications, multi-factor authentication, password rules, and TLS/SRTP encryption, 8×8 does a lot to ensure your company’s calls and data are kept under lock and key.

And 8×8 has some of the best customer support options and availability going. That includes a user forum and a knowledge base to peruse, plus a 24/7 live chat function and phone line for those out-of-hours issues. Email support is also available for your less time-sensitive queries.

Are there any downsides to 8×8?

Comparatively expensive

While 8×8 offers a comprehensive suite of features, its pricing can be comparatively expensive, ranging from $24 to $140 per user per month before 8×8 using a private pricing structure, which might not attract SMBs or startups. That newly custom, quote-based pricing also creates a lack of transparency which many businesses may find unappealing to be locked into.

• For the lowest price: We recommend Zoom Phone since it offers plans from just $10 per user per month.
• For similar features at lower cost: With pricing from $19.99 to $39.99 per user per month, Vonage provides a solid balance of affordability and functionality.

Potentially complicated

Given its wide array of features, 8×8’s tools can be a little more extensive to get to grips with. And that can make it more complicated to use.

• For a streamlined package: Ooma Office and GoTo Connect are known for their straightforward setup, easy-to-use interface, and more streamlined set of features.

Could have greater integration options

And while it has more integration options than many providers, with around 60 different third-party options supported, it is trumped by one rival.

• For the most integration options: RingCentral has over 300 integrations with popular business applications such as Salesforce, Microsoft Teams, and Slack, facilitating seamless workflows.

2. RingCentral

Best VoIP Provider For Customer Service Teams

Why is RingCentral the best VoIP provider for customer service teams?

In our overall standings, RingCentral is a close second to 8×8. While it might be marginally less solid as an all-rounder, we do believe it to be an excellent option for customer service teams specifically.

Customer service teams have to deal with a lot of incoming calls, and RingCentral boasts a great range of features to help make light work of this, including a virtual receptionist, local toll-free numbers and customizable greetings on all of its plans. Upgrading to a Premium or Ultimate plan will also enable you to set up ring groups and call queues, to organize your callers even more smoothly. RingCentral also comes with external video calling and SMS features, giving your customers more ways to get in contact with your team.

Of course, training is hugely important in the world of customer service – your team’s phone manner has to be great, after all. RingCentral comes with features that can help with this, including call transcripts, call recording, call monitoring, call whisper, and call barge. Be wary, though, that RingCentral’s cheapest packages don’t offer all of these, so you’ll have to pay a little more for the full breadth of training and monitoring tools.

Finally, it’s worth knowing that RingCentral comes with ready-made integrations with helpdesk, workspace, email, conferencing, and messaging platforms to help unify your comms and easily hold customer data. Once again, though, most of this is only available on RingCentral’s Premium and Ultimate plans.

Are there any downsides to RingCentral?

More expensive than alternatives

Like 8×8, RingCentral’s pricing can be on the higher side, ranging from $20 to $35 per user per month for its standard plans, with premium features available at additional costs. This could be a significant expense for SMBs or startups operating on tight budgets. Our alternative suggestions for less spending are the same as above:

• For the lowest price: Zoom Phone (from $10 per user per month)
• For similar features at a lower cost: Vonage ($19.99 to $39.99 per user per month)

Lacks free international calls

RingCentral is also a poor choice for free international calling since it has none outside of Canada included for US customers.

• For unlimited calling: 8×8 (14 to 48 countries depending on package) and GoTo Connect (over 50 countries on all of its paid plans) both offer extensive free calling packages as part of their packages. Organizations with extensive international communication needs will value these inclusions and avoid incurring extra fees.

3. Vonage

Best VoIP Provider For SMBs

Why is Vonage the best VoIP provider for SMBs?

Vonage is our top choice for small to medium businesses(also known as SMBs) for several reasons. Firstly, it offers excellent value for money (in these stakes, it was beaten only by GoToConnect, our top pick for startups), with plenty of features, including unified communications tools such as video conferencing and team messaging, available even on Vonage’s cheapest plans. Unlimited domestic minutes only kick in on the Professional and Ultimate plans, but these packages are still very affordably priced. 

We know SMBs are often looking for pathways to grow, so it’s great that Vonage did very well in our scalability comparison, too. The ring group, call queue, and call routing features on Vonage’s more advanced plans will help your team handle growing volumes of calls, while call recording, monitoring, and analytics will help you train new staff and ensure the quality of your business’s comms is top-notch.

There’s also the fact that Vonage allows an unlimited number of users on all of its plans, so you won’t be forced to pay for an upgrade once your team hits a particular size. And Vonage’s 99.999% uptime guarantee means it’s unlikely your all-important income will be unexpectedly impacted by downtime, too.

Are there any downsides to Vonage?

Lacks 24/7 customer support

Vonage’s customer support is available via live chat Monday to Friday from 9am to 9pm (EDT), and phone support is available 16 hours daily on weekdays (8am to 12am EDT) and 12 hours on weekends (9am to 9pm EDT). While that may be enough for many businesses – especially given Vonage offers support across a user forum, a knowledge base, live chat, email, and phone support – you can get complete customer support availability with other providers.

• 24/7 customer support: In contrast, providers like RingCentral and 8×8 offer 24/7 customer support, meaning you can get assistance at any time of day (or night).

Could have more integration capabilities

Vonage offers approximately 20 pre-built integrations with third-party business applications. This limitation can hinder businesses that rely on a diverse set of software tools for their workflow and general operations.

• For the most integrations: RingCentral offers over 300+ ready-made integrations, by far the most ahead of 8×8 with around 60.

Feature availability across plans

Certain features, such as call recording and voicemail transcription, are only available in Vonage’s higher-tier plans or as paid add-ons.

• Features included in standard plans: Other providers, like RingCentral and 8×8, include these features in their standard plans, offering more value without additional costs. Since these are included from the get-go, this means businesses may be able to scale their operations more easily with RingCentral and 8×8 than Vonage since there is more scope for additional features.

4. Zoom

Best For Affordability

Why is Zoom the best VoIP provider for affordability?

Zoom’s Phone packages are feature-rich and affordable solutions costing between $10 and $22.49 per month.

It has four pricing plans costing either $10 (for metered calling), $15 (for unlimited calling to US/CA), $18.32 (for 1-99 users + Zoom Workplace Pro), or $22.49 (for 10 to 250 users + Zoom Workplace Business) users per user per month. Each Zoom Phone plan includes the same features too–IVR, queueing and ACD, team chat, call monitoring, call recording, and more.

That makes it a solid choice if you’re looking for a functional VoIP system that won’t stretch out your wallet since it’s cheaper than the majority of VoIPs out there. And its array of tools outcompetes VoIPs like Ooma and Nextiva which have a more restricted menu of features by comparison.

Are there any downsides to Zoom?

Lack of advanced VoIP features

While it has comprehensive video conferencing capabilities, Zoom’s VoIP offerings are less comprehensive than the top providers on this page.

• More advanced calling features: Advanced call management tools, auto-attendants, and call analytics are more developed and extensive in platforms like RingCentral, 8×8, and Vonage, making them preferable for businesses requiring extensive telephony functionalities.

Lack of advanced analytics

Zoom does not offer advanced analytics tools such as real-time reporting, predictive analytics, and other dashboards, tables, and charts to dive into like VoIP-first companies.

• For analytics tools: Nextiva offers real-time data on customer interactions and team performance for similar costs, or you can upgrade with RingCentral or 8×8 and get even more data at your fingertips like call quality, user activity, and system performance.

5. GoTo Connect

Best VoIP Provider For Startups

Why is GoTo the best VoIP provider for startups?

GoTo’s phone system, GoTo Connect, is our favorite VoIP system for startups. When you’re starting a business, you have to make sure you’re getting as much as you can for as little money as possible. It can secure helpful features like unlimited domestic minutes and multiple communications channels (such as phone, video chat, and messaging) for a relatively minuscule price tag.

As your startup accrues a customer base, you’ll need a VoIP system that can help you communicate with potential customers and clients professionally. With GoTo Connect, you can set up a virtual receptionist, customizable on-hold music, recorded greetings, and voicemail capability to give callers a polished experience whenever they get in touch. 

You can also set up local numbers, so customers don’t have to pay to phone you. Better still for budget-conscious new businesses, these features are all available on GoToConnect’s cheapest package.

Of course, likely, you won’t stay at startup size forever. Fortunately, GoToConnect’s unlimited user limit and available call management features mean it’s a scalable system.

Are there any downsides to GoTo?

Lacking some advanced call management features

While GoTo Connect includes standard call management functionalities, it lacks some advanced features such as predictive dialing and AI-driven call analytics.

• For advanced calling tools: Providers like Nextiva offer these advanced capabilities for a decent price, as well as 8×8 and RingCentral if you are willing to spend a little more.

6. Ooma

Best VoIP Phone System For Customer Satisfaction

Why is Ooma the best VoIP provider for customer satisfaction?

Ooma is a top performer when it comes to what it can offer users who need a bit of help (namely, those new to VoIP). That’s because, from the user reviews we collated and assessed from various online sources, it had the highest rating per review.

And that’s not all. Ooma Office is one of the most affordable business VoIP phone system packages for large companies that we’ve come across. It includes video meetings and softphone apps for all your employees and can be customized to meet the varying needs of your different teams. Ooma can be integrated with a variety of productivity tools too (like G Suite) and CRM platforms, so you can keep all your important activities in one place.

Are there any downsides to Ooma?

Missing features

Ooma falls short in the features department, missing some fairly simple tools like call transcripts, call monitoring, and team messaging/document sharing.

• For more features & greater scalability: Since Ooma lacks these features on all plans, it’s not a great shout for scaling your operations down the line. 8×8 and RingCentral are our favorites for these purposes. Plus, you’ll get those missing features on their basic plans. For instance, For example, RingCentral includes team messaging and extensive analytics in its standard plans, whereas Ooma’s feature set is more basic.

7. Nextiva

Best VoIP Phone System For Flexible Set Up

Why is Nextiva the best VoIP provider for flexible setup?

Nextiva is pretty flexible when it comes to setup, as it boasts its own first-party hardware and is compatible with third-party desktop phones like Cisco, Yealink, and Polycom. This is particularly useful if you have a preference for having a desktop phone as part of your VoIP system. Although others, like Ooma, also offer first-party desktop phones, Nextiva strides ahead because it has a wider range of third-party desktop-compatible phones.

With a 99.999% uptime guarantee, 24/7 Live Support, live chat, and onboarding support, we like Nextiva because of its expansive customer support. So you can be confident in knowing that if you crash into trouble when using your VoIP system, Nextiva’s customer service will be there to help.

Are there any downsides to Nextiva?

Less stringent security measures

When it comes to security, Nextiva doesn’t perform too well. Unlike all other providers on this page, it misses out on multi-factor authentication (MFA). It has implemented password rules since our last update of this page, which is an improvement, but you’ll have greater peace of mind with other providers.

• For strong security: You’re better off turning towards 8×8, GoToConnect, or RingCentral if you want the strongest security measures including MFA, password rules, and user permissions.

Limited integrations

Offering around 20 ready-made integrations across CRM, helpdesk, and productivity tools, Nextiva is a little more limited than other providers in this regard. It has big names like Zoho, HubSpot, Salesforce, Microsoft and Google covered but beyond that, you’ll be struggling to get proper integration with Nextiva.

• For wider integration options: RingCentral is the leader here with over 300+ VoIP-related integration options. 8×8 has tripled the amount of Nextiva, too.

The Benefits of a VoIP Phone System

So, why invest in a VoIP phone system for your business? There are plenty of reasons to do so, but these are the most impactful:

How to Choose a VoIP Phone Services Provider

With several VoIP providers available, determining the best fit for your business can be challenging. Focus on these key factors to make an informed choice based on your business wants and needs:

1. Pricing

The cost of a VoIP system depends largely on the number of users, as providers typically charge per user, per month. Providers also offer tiered pricing plans, with higher tiers offering more advanced features. To reduce costs, consider these strategies:

• Opt for a provider with a lower price per user.
• Select a lower-priced tier that meets your essential needs.
• Pay annually, as providers often offer discounts for upfront payments.

For provider-specific pricing for some of the cheaper plans on the market, read our standalone pricing pages for the likes of Zoom Phone, Net2Phone, and Nuacom.

Questions to guide your decision:

• What features does your business need? This will help identify the right tier. SMBs may require fewer tools, for instance.
• How reliable is the provider’s service and support? Check reviews or research to ensure dependable service.

2. Uptime Guarantee and Call Quality

High call quality is a major reason businesses switch to VoIP. Factors like your internet connection, hardware, and Quality of Service impact the day-to-day experience of your calls. To make sure you are getting the highest quality of calls, we recommend:

• Looking for providers with a strong uptime guarantee to ensure reliable service and high-quality calls.

3. Key VoIP Features

The right features can significantly improve your business operations, too. Depending on your industry requirements, you may need or want different features.

For instance, expanding businesses in sales may require coaching features to help new staff navigate calls in their first few weeks. Meanwhile, retail or hospitality businesses might look for a VoIP with an Interactive Voice Response (IVR) to direct customers to the right channels Likewise,

In any case, here are some essential features to look for in a top-line VoIP plan:

• Call conferencing: For seamless collaboration and remote working in almost any industry from education to IT.
• Call queue: Directs customers to the right agent and reduces wait times, useful for industries like healthcare, retail,  and customer support lines in particular.
• Integrations: Syncs with third-party software like CRM systems like Salesforce or Workspaces like Google to streamline customer interactions and integrate with your existing workflow.
• 24/7 live support: Around-the-clock availability means assistance is always available for maintaining call quality and resolving issues promptly. Not all VoIPs offer this, so picking one with live chat or phone lines with all-day availability may be most crucial for businesses new to VoIP and those working outside regular hours.
