What Is the Difference Between the Different Types of PBX Phone Systems?

When it comes to business-to-consumer communication, the phone call is still the most common first point of contact. The availability of an efficient, cutting-edge telephone system is therefore crucial and essential for every organisation. We’ve gone from analogue exchanges to digital and virtual networks as technology has developed, making it more difficult to choose the best phone system for your needs.

A PBX phone system is a type of phone system that allows you to make and receive calls.

A private branch exchange (PBX) is a type of telephone network that is used only within a company. These PBX clients share a number of outside lines that can be used to make phone calls to other people outside the company; these calls are made over the public switched telephone network (PSTN).

Once upon a time, PBX phone systems were only available to huge organisations, but as the prices of installation and administration have reduced substantially over time, any firm can now afford to invest in an office phone system for its employees.

PBX phone systems include features such as greetings, call holding, call conferencing, automatic call distribution, a directory of extension numbers, and call record archiving, among others. According to the type of system you acquire and whether or not you require third-party plugins, there are a number of additional features and functions that are made available.

Telephone switchboards are classified into three groups.

• Analogue PBX (also known as traditional PBX)

Traditional phone systems, also known as analogue phone systems, are physically located on the premises of your organisation as an exchange box. The pricing of this type of PBX system appear to be more than those of other systems at first glance, however the price actually decreases as the number of ports required increases due to scalability and costs determined per employee (see below).

Because of the costs associated with installation, downtime, maintenance, and support, a phone box is used to connect all of the phone lines on the premises (ISDN lines). Given the complexity and specialised nature of older PBX systems, any difficulties must be rectified by a qualified engineer.

Many businesses choose to use traditional cloud iP PBX systems, which come with their own set of charges. The typical configuration is a communications room maintained by your IT department; but, unlike other PBX solutions, this one gives you complete ownership of the equipment. A PBX phone system, which is similar to a virtual phone system, may be just as beneficial for firms with only one location.

• PBX Service Provided by a Third-Party Service Provider

Given the significant advancements in telephone technology in recent years, installing a classic or analogue PBX system has the problem of losing its value as soon as it is installed on the wall.

In order to add new capabilities to PBX systems, extensive engineering in the central PBX on site is required, which can be time-consuming and expensive if your company is rapidly growing and needs urgent applications. With a hosted PBX, adding new features and functionality is as simple as installing a new web browser plugin.

You can still take advantage of all of the benefits of a PBX, Cloud PBX, but your exchange box is virtualized and maintained by your telecommunications service provider. Hosted PBX phone systems are the best phone systems for small businesses since they do not necessitate the use of in-house IT employees to operate or maintain any hardware.


VOIP (Voice over Internet Protocol) systems, which are also known as IP PBX systems, are systems that transmit voice or video through a data link. It may also communicate with traditional public switched telephone networks (PSTNs).

The IP PBX will transform the voice to data, which will then be delivered across the network as individual packets. The use of data networks for voice can significantly reduce the cost of long-distance and international phone conversations, as well as the costs associated with traditional line rental.

An IP PBX solution can exchange calls between VoIP and analogue telephones while keeping the functionality of your traditional PBX phone system. Because it is owned by the corporation, it differs from a hosted or cloud-based solution in that it is not shared with other organisations.

It could be a software-only or a hardware-only solution, depending on the situation.


PBX telephone systems are priced according to their type, the features they provide, and the amount of extensions they provide for your firm. A quote from a telecommunications company such as Elite Telecom will be required in order to obtain an accurate estimate for your small business prolific ghostwriting.
