Best phone systems for small businesses in 2018

Think you can do without an office phone? Think again. Phone systems are a must for any small business. Read our top picks to find the right one for you

Most people today message more than they call, so you’d be forgiven for thinking small businesses can do without a phone system. But when the stakes are high, queries complex, or quick action needed, there’s nothing quite like picking up the phone to drive results.

Of course, this doesn’t mean a full return to the phone age. Today, most office phone systems work together with the mobile technologies you are already using and will help you join the dots between wireless and desk-side communications.

In this article you will learn:


What small business telephone systems are on offer?

In the business world, understanding your phone needs is sometimes not easy. You may have seen PBX and VoIP talked about. But what do they mean and, more importantly, what do you need?

Here, we break it all down for you and clue you in on everything you need to know to make sure you get the right phone system for your small business.

In a nutshell, there are three main types of phone systems:

  1. KSU (Key System Unit)
  2. PBX (Private Branch Exchange)
  3. VoIP (Voice over Internet Protocol)

Each of these systems comes with a hosted (cloud-based) and non-hosted version. Now, let’s have a closer look.

What is KSU?

KSU (or the Key System Unit) is the most basic type of telephone system. It works just like a home phone and is completely wireless. But it has some limitations that may not work for your small business.

It has a restricted number of phone lines that can be incorporated into it (usually between 10 and 40) and lacks the portability and flexibility of other options. That means it’s not that suitable if your business is looking to grow.

What about PBX?

PBX stands for Private Branch Exchange. This means you can use outside lines for making external calls, and your internal telephone numbers can also be connected to a public telephone network or VoIP provider.

But today, PBX phone systems are increasingly similar to VoIP phones. They often have IP points added, so you can host your phone system within the cloud.

And VoIP?

Before we had mobile phones and wireless technology, all our phone calls travelled over the PSTN (Public Switched Telephone Network). This network used circuit switches to connect calls, and all you needed was a telephone and a copper line in your building.

But then the internet came and changed everything, even how we use phones. So, VoIP was born. VoIP (or Voice over Internet Protocol) really just means phone systems that work via the internet, rather than relying on wires.

Today, most people opt for a VoIP phone system. They tend to be the most cost-effective and flexible option – which is ideal for small businesses.

Are VoIP and SIP the same thing?

You may also have heard of SIP trunking. Although VoIP and SIP both support IP (or Internet-based) calls, they are not the same thing. VoIP simply means making calls over the internet. SIP, on the other hand, has a much larger scope. It is a specific protocol that is used to enable a range of multimedia sessions, which include VoIP calls.

5 tips when choosing a phone system for your small business

We know it can seem like a minefield. To make deciding easier, here are the key questions to ask yourself:

  • What features will work for you? – Most small businesses don’t have the luxury of IT departments to help with their technological woes. Maybe you have complicated needs, or perhaps it makes sense to keep things simple.
  • What is your current setup? – Because VoIP requires less equipment and installation, it often helps businesses cut costs. But of course, this can depend on the current infrastructure of where you work. You could already be set up with PBX.
  • Are you growing? – Traditionally, PBX systems come with specific telephones. This could mean that to change the phone system, you would need to buy all new equipment too. But not always – be sure to check with the provider.
  • How is your internet quality? – Since VoIP systems run over the internet, even distance calls can be crystal clear. But if you live in an area where the signal is poor or unreliable, PBX may offer the most peace of mind.
  • How mobile are you? – If you or your staff spend a lot of time working remotely, hosted (or cloud) phone providers will help to keep you connected.


What features should I look for?

That all depends on your unique business needs. But the top ones to consider will be:

  • Call management
  • Speed-dialling
  • Answering machine
  • Conference calling
  • Video calls

The most basic telephone systems will tend to focus on the most common needs (like speed-dialling and an easy-to-use dashboard), whilst more sophisticated models may be able to do everything on the list.

What does your small business or startup need? And what makes sense for you to spend here?
