An introduction to PBX telephone systems
PBX is short for Private Branch Exchange. Most businesses already have a PBX telephone system installed. But how does it actually work? Let’s keep it simple.
For the most part, this analogue phone system is cheap to run, and it’s perfectly suitable for calling up UK clients and companies. However, in this day in age, the basic capabilities of the hardware combined with the lack of software integration limits how businesses can communicate. That’s why many businesses are turning their heads towards VoIP (Voice over Internet Protocol).

But if VoIP isn’t on the cards for you just yet, sticking with a traditional PBX telephone system offers you the following three benefits:
1. With a traditional PBX system, all equipment is onsite. This makes it super-easy to maintain – and if the phone system goes down, it’s usually easy to figure out what’s wrong.
2. When do you hear about the landline cutting out? Well, you don’t really. This means a PBX telephone system provides your business with a reliable means of communication.
3. A PBX telephone system also gives you full control of your phone lines. You can easily hook up new handsets and take old ones away, while there are no external factors outside of the standard rates (which may have an influence on costings).
This, sadly, is where the benefits for an analogue PBX telephone system come to an end. Realistically, the simplicity of the system is limiting to 21st century businesses. Stick the letters IP before PBX, though, and it’s a whole new story.
That’s right, it’s time to hang up on your analogue PBX telephone system – the letters IP (internet protocol) are bringing the good ol’ PBX right into the 21st century.
What is an IP PBX telephone system?
An IP PBX telephone system is a phone system supercharged by internet connectivity.
The ability to make high quality phone calls over the internet is just one side of the story – in actual fact, the phone system offers up a whole host of features that will greatly improve the way your business handles its customers and partners, as well as your data.
Connected to the internet, the system has the ability to channel interactions from all communication networks. Whether you’ve been interacting with stakeholders via an instant messaging service, email or phone, all communication data ends up in one place.
What are the different IP PBX options?
An IP PBX telephone system can be hosted by a provider’s server (Cloud-based), or it can be hosted by your on-site server (on premises). However, each system works differently.
A hosted or Cloud-based IP PBX telephone system can only make or receive calls via the internet, making a solid internet connection essential. When you make a phone call, it’s sent via the internet to your supplier’s server.
It’s then either fed through to the VoIP system at the other end, or converted back to an analogue via an SIP trunk.

You can set up a self-hosted IP PBX system in such a way that you can make and receive phone calls via the internet, or through the local telephone network. This means you always have back up should the internet (or landline) go down.
Instead of sending your call across the internet to a supplier’s server, the call is sent to your own server room, where it either continues on its way as a VoIP call or is converted to an analogue call via the SIP trunks attached to your own PBX unit.
Here are some of the main differences between hosted and self-hosted IP PBX telephone systems:
|Hosted IP PBX||On-premises IP PBX|
|Data hosted by a provider||Data hosted on on-site server|
|Monthly hosting fee||One off payment|
|Internet phone calls only||Internet and landline phone calls|
|Very low maintenance||Potentially high maintenance|
|Hard to expand||Easy to add additional handsets|
|Upgrades handled by provider||Technician required to handle upgrades|
What are the benefits of investing in an IP PBX system?
Discover the main benefits of an IP PBX telephone system below:
1. Gone are the days where you have to fork out an arm and leg to call your clients overseas. Thanks to the internet, the cost of calling stakeholders and clients abroad is far less with an IP PBX phone system. And, providing you both have a good internet service, your phone call will be clear as a bell, too.
2. Mobile integration is one of the biggest benefits of investing in an IP PBX phone system. Because phone numbers are hosted on the web, you can log into your account and use the same number across all of your devices. So whether you’re using your desk phone or your mobile phone in the field, clients and stakeholders will always receive calls from the same number.
3. A consistent telephone number isn’t the only benefit of investing in a Cloud-based phone system. Because all of your communication data is stored on the Cloud, you can access your data from anywhere – whether you’re working from home or checking up on missed phone calls from the top of a mountain.
How will an IP PBX telephone system help your business?
Are you tired of internally redirecting phone calls to the right team member? Luckily, IP PBX software enables you to make the customer journey and your business processes more efficient by offering the following setup options:
- Virtual receptionist – a system that sends callers to the right department by asking questions and understanding verbal responses
- Extension setup – provide each employee with an extension so callers go straight through to the right person
- Call forwarding – automatically knock the call on to the next appropriate phoneline if the intended employee is away from their desk
- Call waiting – signals there’s another call in the queue if you’re already on the phone
And that’s not all. Thanks to telephone management features, you’ll also be able to find and keep track of the following on a department and company-wide basis:
- Incoming and outgoing call patterns
- Caller ID
- Extension numbers used
- Which lines calls are being made from
IP PBX software capabilities
IP PBX software is a clever bit of kit. On its own, it’ll offer your business the following services:
- Video chats
- Conference calling
- Voicemail transcribing
- The option to work remotely
- Intelligent call forwarding
But what happens if you add customer relationship management (CRM) software into the equation? With the integration of this handy business software, you can log customer interactions from all of these channels:
- Social media
- Instant messaging
- Phone calls
The software platform will become a hub where you can easily track where your customers and business contacts are within your various funnels. This will help to ensure that you never miss out on a sales opportunity, or the chance to nurture a business relationship that could benefit you in the future.
How much does a PBX system cost?
There are a number of factors that suppliers consider when calculating the cost of analogue and digital PBX phone systems. The biggest cost will be the initial installation of the system – and if you’re looking to host a digital system in-house, you’ll need to consider the cost of the server, too.
From then on, IP PBX telephone systems should have a low monthly cost. Suppliers usually calculate the monthly cost of a hosted IP PBX system on the number of users and software features required.
The best way to find out the cost of a PBX telephone system is to receive quotes tailored to your business’s specific requirements. You can do that simply and quickly just by selecting your answer below and filling in the form.

Do you already have a Telephone System?
PBX vs IP PBX – which one should you choose?
A PBX telephone system on its own is very basic. At the least, it lets you call other landlines across the country at a cheap rate, and leave a voicemail if the intended person doesn’t pick up. At the most, it allows you to call up your business contact in Australia, but leaves you with a hefty hole in your wallet (we’ve all been stung calling abroad).
That’s not to say that a PBX telephone system isn’t the right option for your business. Certainly for small startup businesses, there may not be a need to invest in a IP PBX telephone system straight away. Instead, you can combine an analogue PBX system with a service like Skype for Business, which you can use for overseas phone calls and meeting scheduling.
For small to medium businesses and above, an IP PBX system will prove invaluable when it comes to running your business more efficiently. With your phone system software helping you to manage your communications and communication data, you have more time to focus on pleasing clients and stakeholders. This is only going to help you grow your business that much quicker.
