Private Automatic Branch Exchange (PABX) systems!

Let's understand more about PABX phone system and how you can implement them into your business operations.
What is PABX?
In simple words, PABX systems are known as private networks within an organisation that allows for communication using various platforms such as VoIP and ISDN. It makes use of a public switched telephone network for connections. This system enables shared phone lines and allows for internal communication through extension numbers. It can handle a large number of virtual phone lines and efficiently transfer calls between employees.
Moreover, PABX phone users can make internal calls without any cost. At first, these solutions were very expensive. However, traditional PBX systems continued to be used and were enhanced to replace the old method of relying on switchboard operators. Eventually, electronic switching for call forwarding or transfer became the norm in most offices, including those without a fully automated PBX.
The various types of PABX systems are as follows:
- Traditional PABX
Traditional PABX systems allow companies to have full control over their communication infrastructure through on-premise hardware. These systems offer advanced features such as voicemail, conference calls, and call routing, making them suitable for companies that require a high level of control and customisation in their phone systems.
- Cloud based PABX
These PABX systems offer flexibility and scalability, allowing companies to easily adjust their system as needed without purchasing new hardware. They are cost-effective, eliminating the need for expensive hardware purchases and offering fixed monthly costs. These systems are always up to date with the latest features and software updates, making them suitable for companies looking for a low-maintenance, adaptable, and affordable solution.
- Hybrid PABX
The hybrid PABX system combines the advantages of cloud computing and on-premise control, offering a seamless communication experience by connecting cloud-based features with existing phone lines. It is ideal for companies seeking a balance between control and flexibility, especially for those transitioning from on-premises PABX to cloud-based solutions.
Now, let's move on to understand how these systems work.
How do PABX systems work?
Have you ever wondered how businesses can efficiently direct calls to different departments or mailboxes? The answer lies in the PABX system, which acts as a small phone network within an office. It functions like a digital switchboard, effortlessly connecting both internal and external callers.
Here is a breakdown analysis:
- Internal network
Each phone in the company is assigned a unique extension number, acting as a virtual "office address" within the PABX system, allowing for direct dialling to colleagues without the need for multiple phone lines.
- The router
The PABX serves as a central point for incoming calls, directing them according to predetermined rules. It can be set up to use an IVR system to greet callers and guide them to the desired department or extension
- Connecting outside
Employees can make calls outside the company using trunk lines, which are shared lines.
Modern PABX systems, which are often based on IP technology, use internet connectivity to route calls digitally. This enables features such as voicemail, call conferencing, and integration with mobile devices, allowing users to access their office extension remotely.
Therefore, PABX systems are:
- A cost-effective and flexible communication solution for businesses.
- Improving internal calling.
- Ensuring professional call handling.
- Accommodating future growth.
