| Starting Price | $19.99/month |

Ooma stands out with an array of features at an unbeatable price point. During testing, I found that it offers business users stable connections and excellent voice quality.
If you need to connect with your organization, Ooma has great video calling features, which include screen sharing – not a feature that all top VoIP providers offer.
The platform also offers an incredibly useful Receptionist feature that automates incoming call management. With this, calls can be routed to the correct department or person with ease.
Finally, Ooma’s Hot Desking allows unassigned phones to be transformed into your business phone for the day, ensuring that no matter who’s using a phone, they can access their own VoIP line.
In short, Ooma is easily among the best VoIP phone services for residential office use and even more so for businesses. What’s even better is that the basic service is free if you get an Ooma Telo device.
You can also try it risk-free for a full month.

Vonage lets you accelerate internal and external business communications, helping your team make the most of their working hours. That said, it stands out with its customizable Admin Portal.
The portal lets you manage your entire business phone system from one dashboard on desktop and mobile devices. Here, you’ll get detailed analytics of the calls categorized by extension.
You can check the number of calls made, answered, and missed, which will help you identify your best performers. This business VoIP system also has great automation and call management features.
For example, to simplify team management and work distribution, Vonage offers a unique Busy Lamp feature that displays the current status of each extension in real-time.
It supports up to 50 lines at a time, which will also simplify call routing. The chatbot will help with customer queries, too, including sending automated notifications to follow up with customers.
Given all this — along with its flexible pricing and 99.99% uptime — it’s no wonder Vonage is the chosen business phone service for over 100,000 companies worldwide.

Nextiva integrates multiple communication mediums in one easy-to-use platform. Even on its most basic plan, you get access to unlimited calling and video calling—making it one of the top small business VoIP solutions.
It lets you set up conference calls with unlimited users. Audio conferencing will also come in very handy for employee training or onboarding, and the same applies to video conferencing.
Depending on the plan, you can add as many users on the call as you want. To simplify getting started, Nextiva also lets you import your contacts from Outlook or Google Contacts.
The platform also has extremely useful integrations with products like Microsoft Teams, Salesforce, and Hubspot, so you can streamline your business communication and processes.

| Top Features | Advanced call management, custom call handling, call screening and blocking |
| Money-Back Guarantee | ❌ |
Phone.com serves over 50,000 brands around the world, including big names like Zoho and LiftMaster. That said, my favorite feature of Phone.com is its flexible pricing.
It has pay-per-user pricing, under which you only pay for the exact number of team members you bring on board, making it much more cost-effective than many other VoIP systems.
As one of the best small business VoIP services, it offers excellent tools for setting call-handling rules, including call screening, blocking, and queues. Another benefit is that every account comes with a free business phone number.
Suppose you go for its Pro Plan, even better. Here, you’ll also get call recording, which is a great way to assess customer satisfaction and employee performance.
Phone.com also provides detailed call analytics, enabling you to make better business decisions about task distribution, resource allocation, and promotions.
Phone.com is one of the cheapest VoIP providers, too, offering great value for money by allowing 10 participants for video conferences, 500 pooled minutes, and 1,000 pooled text segments.

| Starting Price | $15/user/month |
|---|---|
| Free Version | ❌ |
| Top Features | Shared inboxes, free number porting, detailed call analytics |
| Money-Back Guarantee | ❌ |
OpenPhone is highly rated and used by many, including big names like Deel. Its interface reminded us of Slack—every conversation is centralized, and your team’s statuses make it easy to ensure you transfer calls to an available team member.
Each phone number gets a shared inbox, which I found incredibly helpful for keeping conversations organized by location. You can also see call logs alongside text messages for a unified view of all communications.
Your entire team will have one shared address book, ensuring everyone is on the same page about the lead’s status, for example. But what really stood out to me during testing was OpenPhone’s ease of use and customization.
You can also port your existing numbers for free, which is rare. The workflow setup for things like the phone menu, call transfers, and the order, duration, and agents for ring groups is incredibly easy – with simple drop-down menus.
In terms of customization, you’ll be able to specify whether you want calls to be recorded automatically, add a custom caller ID or greeting, and specify business hours for when a number will be active.
OpenPhone lets you integrate with some of the best CRM tools, too, including mammoths like Salesforce, to keep all your customer data centralized. Slack is another, as is Zapier, which gives you loads more.
As you’d expect, OpenPhone also offers a valuable dashboard for analyzing your team’s performance — the number of calls attended to, all text communications, and call recordings — all in one place.
Pros
- Simple yet highly intuitive
- Affordable, excellent value for money
- Boasts an incredible reputation
- Highly (and easily) customizable
Cons
- Some settings are tricky to find on mobile

6. MightyCall — Best VoIP Phone System for Call Management
| Starting Price | $15/user/month |
|---|---|
| Free Version | ❌ |
| Top Features | Supports web phones, AI-powered virtual receptionist, multi-level IVR |
| Money-Back Guarantee | ❌ |
MightyCall offers over 30 VoIP features and is one of the few to offer a free trial. Unlike many VoIP services, it offers two business phone numbers, regardless of the plan you choose.
MightyCall also offers Presence Status for each employee, just like Vonage. It tells you if a certain employee is available, away from the desk, or busy on another call.
Furthermore, MightyCall lets you add extra users to your plan at a nominal fee. On its Enterprise plan, you can add unlimited users. This is a godsend for growing businesses.
That said, beyond all this, handling calls is also a breeze with MightyCall’s Call Flow feature. It lets you create custom rules for how you want calls to be handled.
For example, you can automatically route all blacklisted calls to go to voicemail. Similarly, the white-listed callers or VIPs can be directly sent to a priority support number.
This not only gives your business a more professional look but also ensures that no employee wastes their time on unnecessary calls. You can also set up custom customer greetings.
Pros
- Excellent call recording features
- Multi-level IVR and music on hold
- An easy-to-use interface
- Doesn’t require system installation
- Great call-routing tools
Cons
- Doesn’t offer video calling

|---|---|
| Free Version | ✅ (Video conferencing and virtual events) |
| Top Features | Push to Talk, Unlimited domestic calling, Free video conferencing |

RingCentral is a name worthy of this list of the best VoIP providers as it’s easily one of the best business phone services.
Over 400,000 businesses worldwide know this, including the likes of big names like Toyota and Office Depot. To start with, it offers 99.999% uptime.
Beyond this, RingCentral takes VoIP security seriously and has over 11 certificates to prove it, including HIPAA and GDPR compliance. This makes it popular in the healthcare and retail sectors.
One interesting feature I found was the walkie-talkie capability called “Push to Talk”, allowing employees to use their work mobile phones for effortless communication.
It also offers fantastic team collaboration features. This includes file sharing and even task scheduling, with video conferencing and screen sharing being the cherry on top for an all-in-one business communication solution.
You also get standard features, including the ability to switch from one device to another, call monitoring, and call recording, which is great for training and customer-focused businesses.
Overall, RingCentral boasts an incredibly solid reputation, and you’ll struggle to find any major downsides. For some, the pricing is high, and features like Push to Talk come at an additional cost.

Another feature that most businesses will find useful is Ring Groups. All devices linked to an extension will ring simultaneously or in chronological order so that you never miss out on any important call.
This can be exceptionally beneficial for small businesses that are short on employees. What’s more, it offers stellar customer support that’ll be there for you round-the-clock over call, email, and chat.

| Starting Price | $15/user/month |
|---|---|

| Top Features | Unlimited calling on all plans, Automated spam detection, Visual voicemail |
| Money-Back Guarantee | ❌ |
DialPad is an AI-powered VoIP service provider that centralizes customer and business communications, helping you streamline your day-to-day team activities.
From the cheapest plan, you get access to unlimited calling, SMS, and MMS. Another benefit of DialPad is that you can get local business phone numbers for over 70 countries.
This will help businesses expand into new markets. If you’re approaching an international market, you’ll have better luck connecting with the locals if you have a local business number.
In addition, DialPad is one of the few phone system platforms to guarantee 100% uptime. Furthermore, DialPad lets you have multiple phone numbers on each account.

| Money-Back Guarantee | 30 days |
8×8 is recognized as one of the best business communications solutions for calls, video chat, and contact centers. Currently, over 2 million people use its internet phone services.
Its secure HD audio calling will give your customers a seamless calling experience. That said, my favorite feature offered by 8×8 is its multiple call-handling features.
For instance, its Hunt Group feature lets you automatically route calls to the correct department. This is basically the job of a receptionist, but only 8×8 will do it more efficiently.
Similarly, you can also create Ring Groups where several devices receive phone calls simultaneously. This way, whoever’s free can pick up the call first, reducing your chances of missing calls.
Beyond this, for internal communication, 8×8 provides audio and video conferencing with up to 500 participants simultaneously. Both the audio and the video are of HD quality.

We base our recommendations on first-hand testing. All the VoIP products we feature, have been tested based on the following criteria:How We Review And Test VoIP Services
What is VoIP?
Voice over Internet Protocol (VoIP) is a technology that allows for voice communications to be transmitted online. This means that you can place and receive calls over the internet rather than via an analog phone line.
Voice over Internet Protocol solutions don’t actually require any physical hardware, unlike conventional POTS phones. VoIP providers only require that you have a high-speed Internet connection.
How Does VoIP Work?
A VoIP service is sometimes referred to as a virtual telephony service, cloud-based phone system, virtual calling tool, or online phone system.
VoIP uses the real-time protocol (RTP) to ensure the timely delivery of data packets and can be accessed through an Ethernet cable or high-speed Wi-Fi internet connection. The technology uses the Session Initiation Protocol (SIP), a communication protocol for VoIP calls and other multimedia sessions.
Depending on whether you are using Software or hardware installation, you may need certain equipment to use VoIP, such as a VoIP PBX, VoIP or IP phones, and network-ready devices with VoIP apps installed.
Types of Internet Phone Services
There are different types of VoIP services, here are the core ones explained:
A Unified Communications as a Service (UCaaS) VoIP service offers a mixture of general VoIP functions alongside SIP solutions.
Beyond placing calls over the Internet, these services can integrate with tools your business already uses, ultimately streamlining your daily operations.
These subscription services include text messaging, video conferencing and meetings, document sharing, voicemail transcription, and more, depending on the provider.
Combined, the functionality is designed to help businesses streamline communication and their business processes.
Hosted VoIP, also known as cloud-based VoIP, is a type of service hosted and managed by a third-party provider. You access the service via the Internet and typically pay a monthly subscription fee.
Hosted VoIP systems are popular among businesses because they require minimal upfront investment and offer great scalability and flexibility.
A CPaaS VoIP service empowers developers to incorporate voice calling capabilities into their applications without the need to build and maintain complex telephony infrastructure.
These services offer flexibility, scalability, and customization options, making them ideal for a wide range of use cases, including customer service chatbots, for example.
The Difference Between VoIP and Landline
VoIP vs landline and what is the difference between the two?Landlines are fixed services that run independently of the internet, and although this does have its advantages, VoIP solutions are quickly making landline connections obsolete.
While some landlines can have features like caller ID and call forwarding, overall, the functionality of many VoIP service providers far surpasses what’s possible with a landline.
This includes advanced features spanning reporting, IVR options, and call queue management, to name a few, not to mention that VoIP systems let you streamline your business with integrations and mobile and desktop apps.
Beyond features, a traditional landline offers little flexibility, whereas a cloud phone system like those reviewed here can be used on any device with an internet connection and is easily scalable.
When you choose a VoIP system, you don’t need to worry about installing a new line when your business scales (or the hefty initial and ongoing investments)—simply upgrade your subscription.
Why Do I Need a VoIP Solution?
Whether you’re after the best home office or business phone system, you’re not just buying features. Here are the key benefits to know in the VoIP advantages and disadvantages debate:
A traditional landline can cost businesses $50 per line each month, while VoIP plans are available for less than $20 per line.
Whether you need to make international calls or manage many lines, a VoIP solution is likely to be preferable. Switching to VoIP can result in significant direct and indirect cost savings.
Direct cost savings include lower PBX costs, as seen at LSU, eliminating copper wiring charges, and reduced calling expenses. Indirect cost savings include:
- Increased remote work efficiency
- Reduced utilities and office space expenses, and
- Improved collaboration among team members
All in all, it can be a great tool for making calling faster and easier. You can access a whole host of features, like call recording and call forwarding, that you would never have been able to use with a traditional landline.
Cloud VoIP services let you direct calls from landline phone numbers and phone systems to your mobile phone – so calls can be directed wherever they’re needed.
What’s more, beyond desk phones, by plugging in mobile users, you can move your entire operation if needed without losing access to your lines or business phone numbers.
Hence, VoIP solutions provide an enormous amount of flexibility, which would have been simply impossible in the past. And if you need to scale up?
Rather than installing new lines, you just need to get additional licenses and handsets and can get started straight away.
The quality of voice calls using VoIP technology has improved significantly since its early days, when VoIP calls occasionally suffered from poor voice quality and latency.
With a strong and stable broadband internet connection and ample bandwidth, you should have absolutely no problem with getting superb call quality with any modern VoIP service.
Advanced technologies like noise-cancelling microphones and audio compression help cloud VoIP phone systems deliver exceptional sound quality, allowing for seamless communication without interruptions.
You can tailor VoIP services to your exact requirements rather than limiting yourself to what’s technically possible with a traditional phone system.
A VoIP provider provides a multitude of advanced features, many of which aren’t supported by traditional telephone systems or are only available for an extra cost.
Beyond simply placing voice calls, a residential and business VoIP system includes functionality such as:
- Call forwarding
- Interactive voice response
- Ring groups and queues
- Hold music
- Call recording
All VoIP services offer enhanced communication and efficiency, and they’re increasingly essential for complex organizational business communication.
With a fast and stable broadband internet connection, you can take advantage of these advanced features and boost your competitiveness – and you’ll find that VoIP services are actually more reliable than traditional telephone operators.
VoIP installation is simple and hassle-free compared to traditional phone systems. With a VoIP service, there’s no need for physical phone lines — all you need is an Ethernet connection to the corporate network.
Hosted VoIP services also allow individuals and businesses to focus on their core competencies, as the service provider handles all the technical aspects of the operation.
This makes VoIP an ideal choice for small businesses, start-ups, and home offices without expert technical support – getting started is quick, easy, and painless.
Of course, if you’re in an enterprise business, then the cost savings are only multiplied as you deploy phone services at scale.
Preparing for Landline Service Sunset
In August 2022, the Federal Communications Commission’s order 19-72 passed, allowing telecom companies to stop providing traditional landline services across the country – as long as they offered another option. VoIP is the welcome alternative.
Switching to a VoIP system now will allow your business to get ahead of any mass migration issues and future-proof your services—or, if you’re just getting started, you can avoid this headache entirely.
As VoIP statistics show, VoIP solutions are the modern communication standard, and they can provide an enduring, scalable platform to serve all your organizational needs.
How to Choose the Best VoIP Phone System
With the vast array of VoIP providers, choosing the best VoIP service, whether for personal or business needs, can be challenging. Here are the key factors that you need to consider when deciding:
This is a crucial factor, as the cost of international calls can vary significantly between VoIP providers.
Choose a provider that offers reasonable costs for both local and international calls based on the location of your customers or loved ones, and consider whether you’ll primarily be fielding incoming calls or outgoing calls.
If you need a small business VoIP, this can be a deciding factor for the service you pick.
Different VoIP providers offer a wide range of advanced features, so it’s essential to choose a provider that offers the features that best meet your needs.
Do you want to make regular international calls to family, or do you need a call center set up? Do you want to port your existing mobile phone number, or do you want VoIP phone numbers?
Is a toll-free number important to you? Or perhaps unlimited calls? You should be make this clear when choosing the best business VoIP service.
Pay close attention to the core features included in each plan and any additional features that may be sold as separate add-ons, as this can significantly increase your costs.
If it’s at the right price, though, you may find business VoIP services come with tools that are great time savers for your personal life.
A key aspect of choosing the best VoIP phone provider is ensuring it integrates seamlessly with other tools and systems you use, such as CRM software, email marketing services, and other APIs.
Look for a provider that offers robust third-party integrations and APIs to ensure you can get the most out of your VoIP provider – saving you from spending time on needless data entry tasks and manual tracking and recording of communications.
The quality of the VoIP provider’s network is critical to ensuring that your call quality is top-notch. Most cloud VoIP systems have a reliable, scalable network and offer real-time, 24/7 customer service to ensure that you can get support when you need it.
All of the best business VoIP services included on this guide are rated as providing excellent service regarding voice-over-IP-phone call quality.
