Best VoIP Providers for Small Businesses

Telephonic communication is more important for businesses than ever before. Consider all the different business functions that can be handled over the phone: sales calls, customer service and support, payments, conference calls, and video conferencing, to name a few. There’s also a host of other products and services that can work with your phone system to expedite workflows, such as fax machines, voicemail transcription, call recording, and text messaging.

With the market demanding so much from business phone services, it’s no surprise that more and more businesses are switching from a landline to a VoIP provider.

VoIP is an acronym for voice over internet protocol, or phone service over the internet. Anyone with a decent internet connection can get VoIP—and for some businesses it offers a cheaper and more capable solution than a traditional phone line. That’s why VoIP revenue is projected to grow from $94.1 million in 2016 to $195.4 billion by 2024.[1] 

If your business relies heavily on phone communication, it might make sense to align yourself with a business VoIP provider. But before you enter the marketplace, it helps to understand what you are shopping for, and the potential benefits this service could offer. That’s why we’re going to tell you everything you need to know about VoIP: what it is, how it works, and how it can benefit your business.

Once armed with this knowledge, we’ll give you a rundown of the best business VoIP providers on the market so you can make the most informed decision for your business.

What Is VoIP?

For those that don’t understand telephonic communication, VoIP can seem like pretty heady stuff. But if you boil it down to its simplest form, what VoIP does is turn your voice into a data packet and then sends that data packet over an IP network. To accomplish this, the voice information is encoded using software called a codec. The codec turns the voice information into a digital signal (stored in a data packet), and then another codec turns the digital signal back into voice information when it reaches its destination. 

What this does is allow you to make a call from a computer, a VoIP-enabled phone, or other internet-enabled VoIP devices. Since VoIP runs over an IP network, all of your data is stored in the cloud and settings are accessible through an online portal. The online portal allows you to perform most of the functions you would on a traditional phone, such as making calls and adding new contacts.

VoIP is also referred to as IP telephony, internet telephony, broadband telephony, or broadband phone service.

How Does VoIP Work?

At the risk of sounding too jargon-y, let’s get a better understanding of just how VoIP works. Let’s say you need to make a business call from your office. If you had a landline, you’d pick up a phone that is hardwired to a server located somewhere in your office. With a VoIP device, however, there are three different ways to make a call. Let’s look at all three:


ATA stands for Analog Telephone Adapter. This is the most common way to make a VoIP call. Simply plug your phone into the ATA and you’re ready to start making calls. The ATA allows you to connect a standard phone to your computer or your internet connection for use with VoIP. The ATA will then take your voice information and convert it into a digital signal to be transmitted across the web.


Almost every business VoIP provider allows you to make a call through your computer, given that you have a microphone, speaker, sound card, and internet connection. Simply access the dashboard given by your VoIP provider and place a call. 

IP Phone

An IP phone is a fancy way of saying that a phone has an ethernet port. Having an ethernet port allows the phone to be connected directly to an internet router, giving it VoIP capabilities. 

Benefits of VoIP

Now that we understand what VoIP is and how it works, let’s learn a bit more about why a business would want to bring their phone service online. 

There are really two main benefits to VoIP: price and functionality. VoIP providers generally charge less money for their services than traditional phone service companies. This is because VoIP calls are cheaper to place than traditional calls because they do not use phone lines. Since there are only a finite number of phone lines, calls placed over them can be expensive. Placing calls over the internet circumvents this problem. In fact, many business VoIP providers even offer long-distance calling for free.

When it comes to functionality, VoIP offers several benefits:

  • Mobility: Because VoIP calls are placed over the internet, you can place a call anywhere you want as long as you are connected to the internet and have a VoIP-enabled device. Furthermore, because your information is stored in the cloud, you never have to worry about losing data when you transfer services.
  • Features: Having telephonic information transferred over the internet allows for some other tech-savvy functionality. For example, many business VoIP providers offer voicemail-to-text transcriptions that can be sent directly to your email. Other common features include the ability to create conference calls and record phone calls. 
  • Call routing: Many VoIP systems allow you to adjust your settings to determine when you receive phone calls and how. For example, you can have a call first be forwarded to your office. If you don’t pick up after a few rings, it can then be forwarded to your phone or laptop. 

How to Pick the Best VoIP Provider for Your Business

As you can see, VoIP can help your business in many different ways. However, not all VoIP providers are created equal. According to Rick Dionisio, COO at VoIP provider Ringboost, there are 10 items to consider when picking a VoIP provider:

  • Service: Every company will claim the highest quality service in terms of call clarity and outages, but you still need to do your due diligence. Ask about uptime, reliability, and frequency of issues. Ensure your contract includes language about getting prorated refunds for extended outages. See what customers say about the service on review sites. Ask the VoIP provider for references and then, in turn, ask their clients about the quality of service.
  • Pricing and plans: Think about how your business places and receives calls and create an overview of your needs before you review plan options. How many employees do you have? What is your inbound call volume? Does your business require international calling? Use this information to find the plan that fits you best, and don’t be afraid to negotiate for better rates or additional features.
  • Scalability: Ask questions about how the business VoIP provider can grow with you. Some VoIP providers work solely with small businesses, while others specialize in enterprise. Ask about your potential future-state—will you need phone trees (automated telephone systems), IVRs (interactive voice response technology), or multiple extensions? Will growing your account require your contract term to restart or can you expand at any time? 
  • Contract term: Some VoIP providers will require you to sign a two to three year agreement in exchange for lower pricing. Some allow month-to-month. Think about how your needs may change, and look at term requirements as well as cancelation penalties.
  • Mobile app: Most VoIP providers have the ability to forward calls, but a mobile app can give you a full suite of tools to manage your calls on the go. Benefits include enabling you to be able to text from your office phone number and access voicemail messages remotely. For a smaller company where you are out in the field a lot, a great app can make all the difference. 
  • Features and functionality: What is the user experience like, and how can it be customized? Always ask for a walk through of the portal and get a sense of what features you can control yourself without having to reach out to the VoIP provider. What can you access from the portal? Is it easy to set up and to add and remove features? Can it be customized down to the user level? Can you upload your own IVR? Can you do sequential call forwarding? How does the portal sync with the app? Which features require additional cost? If there are features you don’t need, can they be disabled and save you money? If you are starting a new phone service, can you select your phone number(s) and customize it to fit your business?
  • Third-party integration and UCaaS: Unified Communications as a Service is a way to bundle all office communications into a single stream or portal—such as rolling up your phone service with intra-office messenger apps.[2] If your company uses multiple communication channels, ask about the support the VoIP provider gives for third-party service and whether they can come together seamlessly in a dashboard.
  • Customer support: The service that a business VoIP provider gives isn’t just about the phone calls, it’s about the support services. Know what your VoIP service options are: What are the ways you can get in touch? What are the live hours? Is there a guaranteed response time? Some VoIP providers will require you to sign up for a service plan that costs extra.
  • Security: Because business VoIP providers are cloud-based, there need be security measures. Make sure the systems in place are up to par and calls are encrypted. Understand what happens if there is a security issue—will there be down time or are there redundancies and secondary servers that can be fired up to cover call volume? Try to assess how proactive they are about security updates. Look at their latest documentation and see how recently it was updated. Ask about security update communications and ask for a sample security update—is it written in language that you as a customer can understand? Does it give you a sense of trust and comfort that the provider is being diligent?
  • Emergency services: Enhanced 911 (E911) is not offered by all business VoIP providers, so if it is important to you and your business, know whether it is supported or not.
