Discover the best telephone system for your small business

When customers call your business up, they're not just looking for a friendly, helpful person at the end of the line – they're looking for a quick, painless customer service experience.

In a survey carried out by Harris Interactive, 75% of people said it takes too long to reach a live agent. This, coupled with the fact that the average time people spend on hold before hanging up is 11 minutes (, means investing in the right telephone system is important when it comes to retaining and satisfying customers.

Small business telephone systems can traditional, multi-line PBX, or VoIP. While traditional phone systems are the most basic of them all, both PBX and VoIP systems include several user-friendly features to increase efficiency and improve customer experience.

You can find out the differences between traditional, multi-line and VoIP phone systems in the FAQ section of the article. Alternatively, use the ‘Jump to' menu below to skip to the information you require.

Small Business Phone System Costs

For an entire small business telephone system, expect to pay around £170 as a minimum. This will set you up with a full, two line system with up to six extensions.

Higher specification systems can cost up to £1,700. These options have more telephones and extensions with extra user and customer features.

If you're looking for a cost-effective phone system, think about investing in hosted VoIP. While it's hard to pin down an exact price, the fact that the phone system is hosted on a server offsite, and doesn't require expensive set up fees, means you could save your business a lot of money.

No matter which phone system you choose, it's ultimately very difficult to work out the total price of your telephone system without getting quotes that are tailored to you. Luckily, you can do that easily, simply by filling in our short form.

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 many of the hosted systems covered in this guide provide an excellent alternative. By hosting your business phone system externally 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 telephones, it can be hard to know where to start. Fill in this short form to be receive quotes from trustworthy suppliers who can take your needs and turn them into an end-to-end solution.


1. What are the best home business phones?

All of the models listed above are suitable for homes business phones. At the end of the day, it just depends on your preference and your needs.

If your home business phone is to double up as a home phone, take a look at the top 10 cordless models. These are great as both home and business phones, as they leave you free to take calls throughout the house.

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

The long and the short of it is 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 of to different handsets, a VoIP system uses a Cloud-based server.

Find out more information about the two phone systems in the sections below. If you already know which phone system is right for you, compare telephone system quotes, simply by filling in our form.


Traditional phone systems (PBX )

A traditional phone system, is suitable for small businesses with a handful of employees. All you need is one line in, and a couple of handsets so 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 to each handset. 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 PBX phone system are basic compared to VoIP, however you'll still be able to coordinate incoming and outgoing calls, make call transfers, and manage voicemail and extensions.

The great thing is, 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.


VoIP Phone System

Unlike a physical, premises-based business telephone system, VoIP phone systems work by transmitting the phone audio over the internet.

It is important to make sure that your VoIP phones don’t all use the same connection for the internet. Otherwise, you risk garbled or dropped calls if multiple people are online at once.

The number of lines you need for a VolP phone system depends on how many people will use the system at the same time.

For example, a two person organisation will be likely to only need two lines. A 10 person organisation will generally need five to seven lines, and a 100 person organisation could only need 20.

VoIP systems also have hosted (cloud-based) and non-hosted versions.

So what’s the difference between business IP phone systems and VOIP ones?

In short, IP uses a private data network to carry conversations over distance. VOIP uses a public data network. If you don’t have a private network, you’ll need to opt for VOIP. So long as it’s installed properly, you shouldn’t notice a difference in quality.
