Next steps

Finding the right phone system for a small office is vital. A lack of space means small businesses often can’t afford to house large, loud and costly on-premises hardware.

Instead, the hosted systems covered in this guide provide an excellent alternative. By hosting your business phone system externally – in this case, in the cloud – you can instead keep initial investments to a minimum, while affording monthly payments for custom plans and solutions tailored exactly to meet your needs.

Still, with so much choice available, and with so much jargon surrounding the topic of office phones, it can be hard to know where to start. That's why we want to help you cut through the noise, and find the right business phone system for you easily and quickly.

Our free quote-finding service is designed to do just that. To get started, you'll simply answer a few quick questions about what you need. Behind the scenes, we'll match you up with business phone system suppliers that can cater to your needs. They'll then be in touch directly with no-obligation quotes – it's a quick and easy way to find and compare the best options for you.


1. What are the best home business phones?

All of the systems we talk about in this article are suitable for home business phones. After all, many of them come with UC capabilities – such as video conferencing and team messaging – that make it easy to keep in touch with your team remotely. Plus, they're all cloud-based, which means you can access them from any device with an internet connection, no matter where you are.

If you're looking for home business phone models, rather than software systems, check out our list of the best cordless phones for businesses. These will work well in a home office because they can double up as both home and business phones – and they leave you free to take calls throughout the house.

2. How much should an office phone system cost?

This is very difficult to answer definitively, as the costs you'll face will depend on a number of factors, including the system supplier you choose, the size of your business, the type of phone system you want, the features you plump for, and more.

To get a more detailed idea of the exact figures involved, head over to our ultimate guide to phone system prices.

3. Traditional PBX vs. VoIP: what’s the difference?

The long and the short of it is this: a traditional PBX system uses the landline to make and receive calls, while a VoIP system uses the internet.

Both phone systems allow you to receive multiple calls at the same time, but while a PBX uses a digital on-premise switchboard to branch calls off to different handsets, a VoIP system uses an online server. Let's take a closer look:

VoIP systems

VoIP phone systems

VoIP phone systems work by transmitting phone audio over the internet. They come in two varieties: on-premise VoIP, and hosted VoIP (also known as cloud-based VoIP).

With on-premise VoIP, the system is hosted on your own servers. You'll need all the right hardware for this, and you'll need to pay someone with the right expertise to build and maintain the system.

By contrast, a hosted VoIP system lives on your system supplier's servers, and is managed and maintained by your supplier, not you. Over and above all other kinds of phone system, we recommend hosted VoIP to small businesses. This is because it's affordable, it's easy to install, and it tends to come with sophisticated call and UC features for your team to benefit from. That's why most of the systems we review on this page are cloud-based VoIP systems.

Another benefit of a VoIP system is that it can be accessed from anywhere. Most come with an app that your team can download onto a device of their choice, and use to make calls and access the system features – meaning you don't even need to buy desk phones if you're on a budget. If you do choose to, though, you should look for IP phones: these are VoIP-compatible desk phones.

Traditional PBX systems

Traditional phone systems

If you're not ready to upgrade to VoIP, a traditional landline phone system may be suitable for very small businesses with a handful of employees. All you need is one line in and a couple of phones, so that more than one employee can pick up the phone if it rings.

If you tend to receive lots of calls, having one phone line could be holding you back. This is where a PBX system comes in.

A PBX phone system turns your traditional phone system into a multi-line system by giving you the option of adding extensions that lead to each phone. Once a call comes in, the PBX auto attendant directs the caller to the right extension number, freeing up the phone line for another call to come in.

The features of a landline PBX phone system are basic compared to those available with VoIP – which is one of the reasons why we recommend VoIP instead – but you'll still be able to coordinate incoming and outgoing calls, make call transfers, and manage voicemail.

Of course, PBX is flexible in the sense that it can be used with VoIP as well as the landline. In fact, many suppliers give you the option to create an IP PBX system. This uses SIP trunking to connect a traditional phone system to the internet, meaning you can make calls over the internet and benefit from VoIP functionality, in addition to making calls using the traditional landline.

4. How do I choose the right phone system for my business?

When looking for a business phone system, start by asking yourself these 10 questions to help narrow down your options:

  1. How many lines do you need? This depends on how many people will use the system at the same time. For example, a two-person organisation will likely only need two lines. A 10-person organisation will generally need five to seven lines, and a 100-person organisation could only need 20.
  2. How many extensions do you need?
  3. What features would you like on your system?
  4. How many line provider sockets do you need?
  5. Can your phone system expand with growth?
  6. Will you require call forwarding to mobile devices, and their integration into your system?
  7. Will you require call redirection to staff members who work from home?
  8. Do you wish to have a high-speed data network installed, which is able to use wireless technology?
  9. Is there a need for your business to be able to integrate the phone system with the IT used?
  10. Will you need to be able to identify customer details and dial numbers from a computer? This is called Computer Telephony Integration (CTI).
  11. How much are you looking to pay for line rental?
