This is a cloud-hosted VoIP unified communications system that doesn't require expensive PBX (private branch exchange) hardware or a trained IT staff to set up or maintain. All it needs is high-speed internet access and IP phones. This makes setting up and maintaining the phone system an easy task for small businesses.

The service is among the most reliable we found. It utilizes 15 redundant data centers around the world. This ensures that if one goes down, service isn't interrupted. 8x8 boasts a 99.999 percent uptime, which means service is down for just a handful of minutes each year.

Best for Very Small Businesses


Ooma Office is designed specifically for very small businesses. One reason this is a great option for microbusinesses is how the system works. Unlike traditional cloud-hosted systems, Ooma Office combines on-premises hardware with cloud-hosted services.

There are several reasons why this setup is good for very small businesses. Firstly, someone without any technical experience can set up the system in just a few minutes. All you need to do is plug in the system's base unit, which is a full router that can prioritize voice traffic over other online traffic, and then connect the base unit to a high-speed internet router. Additionally, the system is compatible with both analog and IP phones and can be managed in an online portal.

Very small businesses will also be pleased with the included features. While it doesn't have the vast array that some services offer, it does include those that microbusinesses will find most valuable. Among those are voicemail, call transfer, call log, call park, music on hold, extension-to-extension calling and dial-by-name calling.

There is also a virtual receptionist that answers all incoming calls. The receptionist then directs callers to the person or department they are trying to reach. Virtual extensions for remote workers, conference calling and ring groups are among the other important features.

Ooma Office provides good customer service, and its website has valuable resources that will help very small businesses troubleshoot any problems they may run into. This level of support and resources means that keeping this business phone system up and running without a full-time IT team won't be a problem.

Best Virtual Phone System


Grasshopper is specifically designed for businesses with on-the-go employees and is an ideal solution for businesses in need of a virtual phone system. These businesses are looking for a system that allows them to present a professional image at all times, regardless of where their employees are working from. Grasshopper allows for that by connecting business phone lines to remote workers on their mobile and home phones.

The system works by providing each business with its own dedicated phone number and each employee with their own extension. When a customer or client calls the main business line, they are greeted by an automated attendant, which then connects the caller with the employee they are trying to reach. Instead of connecting the call to an office phone, the system sends the caller to any phone of the employee's choosing. This could be a mobile phone, a home phone or any other number.

Employees have full control of where callers are directed. They choose the numbers they want their calls forwarded to and the order in which those numbers are rung. From the caller's perspective, the experience is exactly the same as calling a traditional phone system.

Grasshopper includes a number of other important features, such as voicemail, voicemail-to-email, voicemail transcription, on-hold music, dial-by-name directory, call screening, online faxing and business texting. Each user can also host conference calls with up to 10 participants at a time.

Grasshopper has a sophisticated mobile app that allows employees to make and receive calls on their business lines and send and receive business text messages. This helps ensure that personal calls and texts stay separate from business calls and texts. Additionally, the app lets users make and receive calls using an internet connection, instead of their cell reception.

Best for Call Centers


Mitel offers a comprehensive phone system that can serve not only all of your regular calling needs, but also any call center needs your business may have.
What makes Mitel such an impressive option is its flexibility in hosting options and service plans. While many phone systems only offer cloud-hosted or on-premises hosting, Mitel offers both. You can choose to host the system in the cloud and not worry about any maintenance or service upgrades, or to host it on your business's premises so you have total control over how the system works.

Mitel offers similar flexibility in service plans, with three different plans that vary in price and included features. What's nice is that not all employees need to be on the same plan. Your business can choose the plan that makes sense for each employee, so you aren't paying for all features and tools for an employee who doesn't need them.

Businesses with call center needs are looking for two main things from a phone system: a unified communications system that can support the calling and collaboration needs of their entire organization, and all of the tools to run a productive call center. Mitel checks both of these boxes. It has a feature-rich phone system filled with valuable calling, collaboration and mobile tools. These include an auto-attendant, hold music, call screening, call blocking, the ability to dial by name or extension, voicemail-to-email, Microsoft Outlook integration, online faxing, call blocking, and both audio and video conferencing.

The call center services are tacked on to Mitel's regular business phone system. The features call agents have access to include a variety of queue options, integrations with numerous CRM solutions and call recording. It also offers several valuable supervisor tools, including the ability to listen in on agent calls.

Unified Communications

Today's business phone systems offer much more than just a way to make and receive phone calls. A number of today's solutions, including some of our best picks, are considered unified communications systems.

Instead of focusing solely on a business's calling needs, unified communications systems support all of the ways employees now communicate with customers, clients and co-workers. This means not only traditional phone calls, but audio conferencing, video conferencing, instant messaging, online faxing and text messaging.

While many organizations offer these services to their employees, each component used to be provided by a different vendor. A business might have had one provider for its phone system, another for its conference calling and a third for its video conferencing. Unified communications systems tie all of that into one platform.

These are the main components of a unified communications system:

  • Phone calls: This is traditional phone service that allows employees to make and receive calls.

  • Conference calling: Unified communications systems include a conference bridge that allows each user to host their own conference calls. The number of people who can be on a call at one time depends on the provider. Some systems allow conference calls with 5-10 people, while others allow for hundreds of people at one time.

  • Video/web conferencing: This allows employees to host video meetings with video conferencing hardware, or via a computer equipped with a camera and microphone. Employees can host meetings and see others' faces on the call. In addition, most of these services allow for screen sharing, which lets everyone in the meeting view documents or presentations together. The number of participants who can be on a video call at one time varies by provider. It can be just a handful or as many as 100.

  • Instant messaging: Many unified communications systems include the ability for employees to instant message each other. By logging in to the system, they can send messages back and forth to ask questions and collaborate on projects.

  • Text messaging: Some solutions allow you to send text messages from your business line. Since texting has become so popular, this allows employees the ability to send messages without giving out their personal numbers.

  • Faxing: These systems allow users to send online faxes rather than using a dedicated fax machine. They can send a fax to a recipient's email or fax machine from the platform.

Having all of these tools on one platform can make communication much easier for employees, in turn making them more productive.

Cloud-hosted systems have really driven the expansion of unified communication systems. Instead of paying tens of thousands of dollars for an on-premises system that house all of these features, cloud-hosted services offer all of this for a low monthly, per-user fee.

Business Phone System FAQs

Q: What is unified communications?

A: Unified communications is the ability to access all of your communication tools from one platform. Many of today's business phone systems are in fact unified communications systems. While these systems still offer traditional phone service, they also include a number of other communication tools that professionals now rely on.

Among the added features in unified communications services are audio conferencing, video and web conferencing, instant messaging, and text messaging. Previously, in order to use all of these communication tools, organizations had to use a different service provider for each. Unified communications streamlines the process by allowing you to access all of these tools from the same company. This not only boosts production among employees, but can also be a significant cost-saver for businesses.

Q: What should I look for in a business phone system provider?

A: There are multiple factors to consider when choosing a business phone system provider. First and foremost, you want to ensure the system has all of the functionality and features your business needs. Can it support the number of employees who need the service? Does it have all of the features your business relies on or would benefit from?

While some businesses only want standard calling features like caller ID and voicemail, others want added functionality like ring groups, automated attendants and on-hold music. Also consider any other communication tools your business needs, like video conferencing and instant messaging.

Another factor to consider is a business phone system's reliability. A phone system is of no use if it isn't always up and running when you need it. This is especially important for a cloud-hosted solution. Be sure to ask each provider what its annual uptime percentage is. If it isn't 99.999 percent, find out what the company is doing to correct those issues. In addition, be sure to ask about its service-level agreements and if it has any uptime-related clauses. Many business phone system providers will give users money back if the system doesn't hit a certain uptime percentage.

Finally, what type of customer support does the company offer? If you don't have a full-time IT staff that can handle any issues, you want a business phone system provider that will be available to answer questions when you have them, preferably through multiple channels and online resources.

Q: What is the best business phone system?

A: Since every business is different, it is hard to say that one business phone system can fill the needs of every business. That's why our recommendations for the best business phone systems are based on specific use cases, like best for small businesses, best for remote employees and best for call centers.

For each use case, we looked at the functionality and tools those types of businesses would need from a business phone system. We then compared and contrasted the various phone system providers based on those criteria.

After conducting our research, we recommend 8x8 as the best business phone system for small business, Ooma Office as the best business phone system for very small businesses, RingCentral as the best business phone service, Grasshopper as the best virtual business phone system and Mitel as the best business phone system for call centers.

You can read specifics on each selection above and in our in-depth reviews, as well as more details on how we selected our best picks.

What to Expect in 2019

The uses and capabilities of business phone systems will continue to expand in 2019. One trend sure to continue is the growth of unified communications systems. Businesses no longer use their phone systems to simply make and receive phone calls. These systems are also being used for instant messaging, video calls and faxing.

Research from RingCentral shows that many employees struggle to balance all of their communication outlets. More than 70 percent of workers say their communications volume is an obstacle to getting work done, with 68 percent saying they toggle between different communication tools at least 10 times a day. Of those employees, more than 30 percent say going back and forth between their different outlets causes them to lose their train of thought.

"Today's workforce is under siege by a flood of communications apps," said Riadh Dridi, chief marketing officer of RingCentral, in a statement. "More than ever, our attention is scattered across a wide array of different apps and communications channels. These apps are meant to bolster our productivity, but managing myriad apps is proving difficult – with serious repercussions for businesses."

Employees appreciate access to all of their communication tools from one platform, according to the data. The study discovered that 67 percent of workers believe it helps them achieve better workflow, while 65 percent say it makes them more productive. 

With that in mind, we expect an increase in the number of businesses adopting unified communications systems to increase productivity among their employees and consolidate their communication tools.  

As more organizations adopt these systems in 2019, you can also count on more phone system providers to look for ways to beef up their unified communications offerings. For example, in recent months, 8x8 launched a new team messaging tool for enterprise organizations, and RingCentral unveiled a new UC-specific mobile app.  

Any business phone system providers still focusing solely on phone service will certainly be looking to see how they can expand their offerings to include more communication options. Providers that don't move toward a unified communications platform will likely see many of their customers switch to a provider with that level of functionality.

Researching Each Service

Next, we researched each provider by investigating its services, watching tutorials and how-to videos, and reading user comments. We also contacted each company's customer service department, posing as business owners to gauge the support each provider offers. Finally, we considered the pricing that was viewable on these services' websites or what was quoted to us during customer service calls. We analyzed each system based on the following factors: deployment options, level of service, reliability, customer service, calling features, collaboration tools, mobility options, cost, and Better Business Bureau accreditation, ratings and complaints.
