Published : December 12, 2022Time and technology have significantly changed the consumer telephony landscape, especially with the latest innovation being the VoIP (Voice Over Internet Protocol) business phone system.
Now, business communication has become easy and cost-effective. The “IP” in VoIP marks the beginning of a new era of business communication, with the internet being the underlying transport technology and not cables.
Telephony technology like PABX systems generally uses Voice Over Internet Protocol to offer businesses enhanced global communication experiences.
What is PABX System?
PABX stands for Private Automatic Branch Exchange System. It is a business telephony system used for internal and external communication at a business. This is done through channels like analog, ISDN, or VoIP.
PABX allows businesses multiple extensions with a single extension number. This mitigates the need to use multiple landlines linked to the public network, which is a costlier alternative.
A Private Automated Branch Exchange system can be connected to several devices in an organization. And each of these devices have a designated extension number.
PABX phone systems are available as virtual or hosted solutions and as on-premise solutions to be run on your hardware. They are generally owned and administered by the hosting company.
They are the preferred choice of telephony for many call centers, SMBs, startups, and large enterprises.
PABX vs PBX: What are the differences?
Many people need clarification about the PABX system’s meaning. This is because PABX is a relatively new term and PBX and PABX are somewhat synonymous. They both are telephone switching systems.
However, they are not entirely the same. In simple words, PABX is an improved version of traditional PBX.
In traditional PBX systems, switchboard operators in telephone exchanges are used to route calls. These operators manually plug wires to connect a call to the right receiving line – establishing a connection between two people using Plain Old Telephone Service, also known as POTS. This manually run business’ point system is called a Private Manual Branch Exchange (PMBX).
Now, a PABX does away with the manual part and uses computers instead to automate the switching process – this is the key difference.
Today, traditional PBX as a term is used to refer to both automated and manual switching systems. You can connect it to your on-premise devices using SIP (Session Initiation Protocol) Trunking or even host on-cloud.
How does a PABX system work?
PABX helps optimize how a business communicates internally, with external stakeholders, and with customers.
A PABX works as a personal, internal phone network that houses modems, adapters, routers, telephone handsets, and even fax machines.
This mitigates the need to access any external public network when making calls inside the organization.
- The caller dials a relevant extension number, taking them to a particular receiving line.
- An Interactive Voice Response (IVR) system now plays pre-recorded options and prompts the caller to either speak or press a button to respond. It will analyze the response and automatically route it to the relevant department.
The outgoing calls will, however, need to connect to the public network through trunk lines. These trunk lines are shared by staff members across extensions and handsets. This might cause quality issues during high-frequency call times.
To tackle this, business phone systems are now rapidly moving toward the cloud. This internet-based infrastructure mitigates the need for heavy copper wiring and junction connections apart from offering a seamless calling experience.
Moreover, cloud systems auto-update and manage networks directly from a remote computer terminal or a smartphone. This helps the extension lines to operate optimally.
Cloud-based PBAX also connects to a shared team list rather than one handset. So, in case of an agent’s unavailability, the next available agent can fill in.
Additionally, businesses can make and receive calls globally at a cost-effective rate. VoIP calls help companies cater to international audiences, effectively collaborate with offshore stakeholders and manage remote teams.

Pros and Cons of PBX and PABX
Private Branch Exchange Systems (PBX) and Private Automatic Branch Exchange Systems (PABX) are two commonly interchanged terms. Rightly so because the only difference between the two is automated switching.
Let’s understand the main pros and cons of PBX and PABX:
Private Branch Exchange (PBX)
The PBX system is the “legacy” system that was found in all workspaces after 1950, making POTS altogether oblivious. PBX fundamentally works on a landline network and uses manual switchboard operators to connect calls in an organization – internally and externally.
Pros
- Houses more features than the plain old telephone system
- Mitigated the need for installing multiple phone lines.
Cons
- Efficiency decreases in manual operations.
- Long holds.
- No special features.
- Reliant on the landline telephone network.
Private Automatic Branch Exchange (PABX)
As technology progressed, business communications developed. First-generation PABX phones allowed users to connect by merely pressing extension codes on their phones.
After the advent of the internet, VoIP PABX systems became the first choice of all. They offered revolutionary features and benefits.
Pros
- No need to install complex copper wiring.
- Enjoy almost instant connections.
- One PABX system suffices for all branches of a business, even globally.
