Best Phone Systems for Small Businesses

What is a Business Phone System? 

In short, business phone systems are solutions that bring your company’s telephones under one roof. 

Business phone systems often include call forwarding to various sources, conference call support, automated answering, on-hold call queuing, and more. 

There are three main types of business phone systems: Key System Units (KSUs), Private Branch Exchanges (PBXs), and Voice over Internet Protocols (VoIP). 

Each type comes with its pros and cons. For instance, since VoIPs use the internet, businesses can connect with their employees or customers anywhere, at any time. In our opinion, VoIPs are the most popular business phone systems right now. You might already have the experience of getting calls from VoIP callers.

However, they require a stable internet connection. Otherwise, you may experience interruptions and delays.  

Choosing the Right Small Business Phone System

Before we dive into the list, let’s discuss what you need to consider when choosing a business phone system. 

First, you’ll need to choose the business phone system type that fits your needs. We’ll discuss this in more detail later in the article.

Second, there’s compatibility. You’ll use the phone solution of your choice along with other tools in your company. Picking a phone system that easily integrates with ticked management or CRM software, email providers, and more is crucial.

Third, there’s the cost. You need to account for setup, hardware, licensing, and subscription costs. 

In all, we’ll compare small business phone systems on:

  • How well it fits your needs
  • Compatibility
  • Pricing

Let’s look at some of the best small business phone systems.

How much do phone systems cost? 

You can expect to pay anywhere from $15/user/month to $60/user/month. 

Keep in mind that most of these prices are found in yearly subscriptions. The cost will be slightly higher if you’d like to pay monthly.

Moreover, some features, like more comprehensive integrations, hide behind an additional paywall. These come as add-ons, which might cost an extra $10/user/month. 

However, if you’re a small business owner with basic phone system needs, $15-$25/user/month should be enough. This budget gives you access to most entry-level plans handling the essentials, like call recording, conference transcriptions, and call forwarding. 

Mid-sized businesses may need to look at around $25-$40/user/month, while large companies may expect to pay anywhere from $40/user/month to $60/user/month. 

Another factor you’ll need to consider is that some business phone systems modify their pricing based on the number of employees you have. In other words, companies with large teams usually pay less per user than small businesses with few employees.

Lastly, there’s the hardware to consider. 

Most VoIP phone systems do not require desk phones. They often come with a mobile application you can link to your smartphone or desktop and use as a traditional desk phone. 

However, if you wish to purchase hardware, the pricing depends on the business phone system type you want to use. 

For instance, PBXs may require around $6,000-$7,000 to prepare the infrastructure for a team of around 20 employees. This price includes on-premise servers, routers, cards, switches, etc. 

Setting everything up, you’ll likely require a specialized technician to set you back $1,000.

Moreover, there are licensing costs. Software licenses for PBX system hover around $4,000/year for 20 users. 

Then there are the phones, which range from $50 to $500 per piece. 

In contrast, if you choose a VoIP system, you’ll only need to purchase VoIP-compatible desk phones, which hover around the same price.

What are the different types of phone systems? 

There are three types of phone systems: Key System Units (KSUs), Private Branch Exchanges (PBXs), and Voice over Internet Protocols (VoIP). Let’s cover each one in more detail: 

Key System Units

KSU is a multiline telephone system that uses a central hub (the KSU) to handle functionalities like internal calling. 

The KSU can take the form of a desk phone. It has buttons dedicated to each phone line. 

These units also offer basic features, like paging, hold buttons, speakerphones, and intercoms. 

Unlike PBXs, KSUs cannot switch calls. Instead, KSUs manually redirect calls to an operator system or central calling hub, also known as a PTSN Exchange. 

KSU is best suited for small businesses. They are cost-effective, easy to use, and include all the features necessary for small teams to conduct their activities. 

That comes with its drawbacks, though. They can hold up to 40 lines, and due to their basic functionalities, KSUs are unsuitable for scalability.

Moreover, KSU does not offer much in terms of portability and flexibility. However, you can fix this with KSU-less systems. In layman’s terms, KSU-less systems act as regular KSUs but are not bound by the central switching unit.

Private Branch Exchanges 

PBX phone systems are private phone networks that allow users to communicate internally and put a pool of external lines that agents share to contact and receive calls from outside the company. 

PBXs use programmable switching devices, allowing for automatic call routing. Other common features include call forwarding, transfers, queues, voicemails, auto-attendants, customized greetings, etc. 

Overall, PBXs are an excellent fit for large businesses. They are mostly automated, while a physical phone line can be divided into multiple lines, allowing you to connect multiple phones. 

Furthermore, PBX systems often include a separate power source. Therefore, you can use PBX for a while even after you’ve run out of power. 

Regarding drawbacks, PBXs are costly and require quite some time to set up. They also occupy plenty of space. That said, you might need a dedicated server room. 

Voice over Internet Protocols 

As the name suggests, VoIP allows you to make and receive phone or video calls through the internet without relying on landlines. 

You can use VoIP with dedicated telephones, regular smartphones, or computers. This gives you more room to wiggle in costs, as you can purchase dedicated VoIP hardware or simply use what you already have. 

Speaking of pricing, as seen in the article, plenty of VoIP service providers appeal to businesses of all sizes. VoIP systems bring better value for money and are more scalable. 

Another advantage of VoIP systems is that they give you a much larger reach, as you can contact customers from different countries.

As for the disadvantages, VoIP systems’ performance depends on your internet connections. Weak connections will cause delays and frozen communications. Also, VoIP may leave you prone to cyber-attacks. 

Benefits of Business Phone Systems 

Unified Communications

Business phone systems unify communications. In other words, your employees can message, call, or hold video conferences through a single interface. This eliminates the need to jump from platform to platform, ultimately streamlining your workflow and improving communications.

Call Whispering

Most phone systems enable managers to tap in whenever a call agent converses with a prospect. From there, managers can easily give employees verbal feedback during conversations to help close deals or address customer issues more effectively. 

Meanwhile, prospects won’t be aware that there’s a third person involved in the conversation. This function is also known as call whispering. 

CRM Integrations 

CRM integrations help businesses improve the customer experience. Caller ID technology can display crucial customer information on your employees’ screens each time they call a specific customer. 

This allows call agents to quickly get familiar with their prospects and choose the right approach when communicating with them. 


One of the most significant advantages of business phone systems is that they grow with your company. Regarding cloud-based solutions, expanding your reach and accommodating more employees is just a matter of upgrading to the next pricing plan. 

In terms of physical phone systems, adding new phones is much easier once you have the infrastructure in place. 

Streamlines Workflows 

Lastly, business phone systems make your employees’ jobs much easier. 

With features like auto-attendants, automated call routing, team messaging, and omnichannel communications, phone systems eliminate most monotonous tasks and give call agents more room to focus on what matters — talking to your customers.

How Do I Choose the Best Small Business Phone System?

Decide Between On-Premise and Cloud Phone Systems 

All types of phone systems mentioned in the article, including PBXs, can also be accessed entirely through the internet. These are known as cloud phone systems. 

Both on-premise and cloud phone systems have their advantages and disadvantages.

For instance, on-premise solutions ensure stable voice quality at all times. Moreover, these systems can easily be controlled, configured, and maintained in-house, but you’ll probably need an employee specialized in this field.

In terms of costs, on-premise solutions often require a one-time payment for initial set-up and hardware. In contrast, cloud phone systems operate on monthly subscriptions. 

However, you’re also responsible for maintaining your on-premise phone system. Costs may vary depending on your chosen phone system, and you’ll likely experience downtimes. 

On the other hand, cloud phone systems are more flexible, as they enable employees to work from anywhere. They also do not require any installation costs and are easier to maintain. Since cloud solutions do not need manual updates, you won’t have to worry about downtimes. 

But their performance is strictly bound by your internet connection. If you don’t have a stable connection, cloud systems may cause you many headaches in the long run.

Strike a Balance Between Ease-Of-Use and Features

Next, you’ve got to figure out how advanced your business phone systems should be. 

It might be tempting to pick a provider that offers state-of-the-art functionalities, but that may cause trouble in terms of usability. Not to mention that these features may come at a steep price. 

If you’re a start-up or small business without any prior experience in phone systems, it might be a better idea to pick a solution that offers basic functionalities, yet excels in ease of use. 

Once you’ve learned the ropes, you can upgrade to something more advanced. 

But in any case, the phone system of your choice should include features like auto-attendants, call transfers, conferencing, voicemail transcriptions, call recording, analytics, and control over active calls. These features will generally help increase productivity.

Consider Scalability 

Lastly, you’d want to pick a phone system solution that grows with your business. 

Constantly switching from system to system will cause plenty of headaches in the long run, as you’ll need to retrain your employees continuously. This can also cause a decrease in customer service quality, as call agents wouldn’t know how to use the platform effectively. 

In other words, look for business phone systems that offer pricing plans accommodating all types of businesses. Add-ons are also a good idea, as what you pay is what you get, bringing good value for money. 

Furthermore, consider the platform’s integration capabilities. The ability to link a phone system with a CRM platform or other team communication tools will greatly improve your team’s productivity as your company expands.

Business Phone Systems FAQs

Which is the best small business phone system? 

Generally speaking, you can’t go wrong with Ooma. The platform prioritizes accessibility, making it a perfect fit for those new to phone systems. 

Besides, Ooma offers many features in its starter plan, including a virtual receptionist, music on hold, ring groups, etc. Coupled with its price tag, Ooma brings excellent value for money. 

How do phone systems work? 

It depends on the phone system type. For instance, Key System Units (KSUs) are physical units that contain various buttons, while each button represents a phone line. 

The call agent picks up the receiver and presses the button corresponding with the line they want to select. To switch calls, an agent must manually route the call to a central calling hub, and the switching will take place there. 

In contrast, Private Branch Exchanges handle this automatically, using programmable switching devices. 

Meanwhile, VoIP systems deal with everything on the internet. Think of them as business-oriented versions of WhatsApp or Viber. You can call anyone, from everywhere, on any device without needing dedicated, on-premise phone systems. 

VoIP systems include all the functionalities you would expect from a business phone system, like call transferring, routing, etc. 

What are unified communications? 

In short, unified communications aim to bring all business channels under one roof. Systems with unified communications allow companies to contact their teams or customers via a single interface via text, voice calls, video calls, and more.

This eliminates the need to switch between platforms to contact staff or prospects on multiple platforms. 

How many phone lines are provided with business phone systems?

As many as you’d like. You can opt for multi-line phone systems ranging from two to six lines and beyond. However, this choice depends on your business’s size. 

A two-line system may work for you if you’re a solopreneur. This helps you prioritize your calls and appear more professional in your customers’ eyes. 

On the other hand, a four-line system should do the job if you run a small business with multiple teams, like a sales and customer service department. This helps your teams communicate effectively, while each can prioritize and handle external calls without any issues. 

You can also set up a dedicated fax line while you’re at it. 

Lastly, six lines or more are recommended for large companies. For example, they can set separate lines for each project manager and each team member to ensure maximum effectiveness.

How do business phone systems improve collaboration? 

The answer is simple: Most phone systems offer unified communication. Texts, video conferences, and voice calls are accessible within a single dashboard. 

This gives team members a centralized place where they can handle communications. Moreover, some platforms include team collaboration-specific tools, like file sharing, screen sharing, and integrations with other collaboration platforms. 

How do you set up a small business phone system?

If you choose the cloud-based phone system approach, setting up a system is just a matter of signing into your account and connecting your phone numbers and devices to the platform.

If you opt for an on-premise phone system, there are a few more steps you’ll need to take. First, you’ll have to purchase the hardware itself. Moreover, you’ll need a space where you could hold the hardware, like the power source, trunk lines, etc. 

After that, you can connect your desk phones to the business phone system.


Overall, using a business phone system in your company is an excellent idea. 

It improves customer service by allowing you to reach prospects across all channels from a single dashboard, and it gives you all the tools necessary to gauge your teams’ performance and provide feedback. 

Meanwhile, employees can easily communicate and automate monotonous tasks, thus increasing productivity. 

But with so many options available, finding a phone system that suits your needs may be a little challenging. Let’s go over a quick recap:
