PBX, or Private Branch Exchange, is a business phone system that connects multiple lines for internal and external calls, offering advanced features like call routing, voicemail, and call management. Designed to streamline communication within an organisation, PBX systems enable efficient handling of calls across various departments and teams.
With a host of attached benefits, PBX also comes in a variety of forms. This way, organisations across multiple market segments can deploy the right communication solution for their needs. Whether the organisation is a small, medium, or large business.
Essentially a private telephone network used within a business, PBX allows users to have more phones than physical phone lines. This is because, rather than using actual phone lines, PBX uses extensions in order to redirect calls to the business number.
A PBX can handle all internal communication traffic. Importantly, PBX acts as somewhat of a gatekeeper when it comes to communication requests from the outside world.
PBX establishes a circuit between two communication endpoints by mapping the dialed number to an endpoint like a telephone.
From there, PBX actively maintains the established connection through the process of channeling voice signals between the two endpoints. Once the call is disconnected, the final function is to provide information detailing the metering of calls for reporting requirements.
PBX systems' added benefits include:
How is PBX Different from PSTN?
The Public Switched Telephone Network (PSTN) is the traditional landline phone system. It connects phones through a dedicated network, allowing anyone with a phone number to call others around the world. Unlike PBX, which is often used privately, PSTN is public and can support large numbers of users. It also uses standard protocols to connect phones and switches.
PBX and PSTN are both switch systems used for phone communication. PBX is designed for private or business use, connecting internal calls and linking to external lines. It helps reduce the need for a separate line for each user. While mostly used in the private sector, PBX can handle thousands of phones and uses its own protocols to manage connections.
What are the Different Types of PBX Systems?
The main types of PBX are:
Traditional PBX systems use landline technology (such as copper wires) to connect calls across multiple phone lines. These systems are typically stored on-site at the business location.
Key features of traditional PBX include:
Things to keep in mind:
A hosted PBX system is a phone system where the hardware and infrastructure are managed by an external service provider. Unlike traditional PBX, there’s no physical equipment installed on-site. All system maintenance, upgrades, and server management are handled off-premises by the provider.
Key points:
Cloud-based PBX is one of the most advanced PBX systems, operating entirely online. All voice functions, features, and call management take place in the cloud, accessible through a virtual interface. This eliminates the need for on-site equipment and allows businesses to manage communications from anywhere.
Key points:
Also known as a VoIP phone system, an on-site IP PBX uses the business’s internet connection to manage voice calls. Instead of routing calls over traditional phone lines, this system converts voice into digital data and sends it via the internet. Though hosted on-site, it offers more modern features than traditional PBX.
Key points:
Advanced features include:
A hybrid PBX system combines elements of both traditional digital PBX and modern VoIP technology. It allows businesses to maintain their existing phone systems while introducing VoIP capabilities. This blended setup supports both in-office and remote communication needs.
Key points:
When it comes to understanding the difference between Traditional PBX and Cloud PBX, it’s important to remember one key distinction. Traditional PBX systems use the public switched telephone network (PSTN) whereas VoIP systems work to transfer calls over the internet.
While the key point of transmission differs, there are also other differences to consider:
|
Traditional PBX |
Cloud PBX |
|
|
Upfront Investment |
Installing a traditional PBX system requires an upfront time and cost investment. A business will have to source and provide a power supply, routers, software, and hardware. |
Requires Cat5 cabling or Wi-Fi for each device to operate. While cabling comes at a cost, the only other hardware a business will need to invest in is VoIP phones. |
|
Running Costs |
As traditional PBX is housed on-site, which means that the business will need to pay for software licenses, maintenance, and service fees when the need arises, as well as the monthly phone bill. |
When operating under a VoIP model, a business will typically have to pay following a subscription model. |
|
Call Quality |
PBX call quality is typically high and isn’t subject to variables. |
At its peak, VoIP can deliver HD voice calls. However, issues related to insufficient bandwidth or connection errors might impact overall quality. |
|
Scalability |
In terms of scalability, PBX is quite rigid. This is because a business will need to add extra phone lines and install new hardware in order to add new users. |
When it comes to adding more capacity, it’s as simple as ordering more phones and adding the user to the plan. |
|
Reliability |
When installed correctly, PBX is traditionally very reliable. |
In terms of reliability, this will depend on the provider and internet-related variables. |
|
Mobility |
Typically, an on-site PBX system cannot be used outside the office. |
VoIP systems enable users to handle calls from computers or mobile. |
|
Security |
As on-site PBX routes external calls to the PSTN, there is no risk of hacking. |
VoIP systems have the potential to be infiltrated by external parties. |

What is the main difference between PBX and PSTN?
PBX is a private telephone network within a business that allows for free internal calls and shared external lines, while PSTN is the public telephone network that connects phones worldwide.
Which type of PBX is best for small businesses?
Cloud or hosted PBX systems are typically best for small businesses due to their lower upfront costs, minimal maintenance requirements, and scalability.
Can PBX systems support remote workers?
Yes, cloud-based, hosted, and hybrid PBX systems support remote workers by allowing them to connect from anywhere using computers or mobile devices.
What happens if the internet goes down with a cloud PBX?
If the internet goes down, cloud PBX services may be temporarily unavailable. However, many providers offer call forwarding to mobile devices as a backup.
Is a traditional PBX more secure than cloud PBX?
Traditional PBX systems are generally considered more secure against remote hacking since they use physical PSTN connections, while cloud PBX security depends on internet protection measures.
How quickly can a business implement a new PBX system?
Implementation time varies by system type. Cloud PBX can be set up in days, while traditional systems may take weeks to install and configure properly.
