Apart from the convenience and flexibility factors, there are various other benefits of using a business phone system. Recently, providers of several phone systems moved to cloud services. This move has introduced a new revolution in the business world. Small-scale businesses now have access to various telecom features, usually limited to large enterprises. Whether you are a small or large-scale business organization entrepreneur, cloud-based phone systems provide unparalleled degrees of analytics and software integrations. As a result, you get the chance to maximize your business communications across the entire phone system within your organization.

What are Business Phone Systems?

Any multi-line telephone system with several features is a business phone system. Some of these features include:

- Unlimited calling - Call more than one employee or a group of people - Automated menus - Call recording - Email or voicemail functionality

Phone systems are also available in different types, such as PBX or Private Branch Exchange, VoIP or Voice over IP, and KSU or Key System Units.

What is Business Phone System

Understanding the Different Types of Business Phone Systems

When you talk about the business phone systems, there are three types in the market. These are PBX, VoIP, and KSU.

Private Branch Exchange (PBX)

Considered an advanced phone system, private branch exchange or PBX is one of the three types of phone systems. PBX uses various types of programmable switching devices. As a result, it enables the automatic routing of incoming calls. With more than 40 employees, any company will find PBX the most suitable business phone system. The simple reason behind this fact is PBX is an entirely automated system. Another added advantage of using this system is the uninterruptible power supply. This means that businesses can function smoothly even when there is no power.

Key System Units (KSU)

The key system unit or KSU is the most basic system of the three business phone systems. This makes it suitable only for small-sized businesses with less than 40 employees. In addition, KSU can incorporate a limited number of phone lines. It is a user-friendly system and functions much like the standard home telephone. Although it has all the necessary features essential for a business, it lacks flexibility and portability. This phone system uses a central switching system, which is the KSU. As a result, you need to determine the telephone-line selection manually.

Voice over Internet Protocol (VoIP)

The most popular among the three types of business phone systems is VoIP. It is the most advanced system and allows a phone operator and possible clients to communicate even from two different countries. VoIP needs to use the internet and a computer to work. Due to the advanced features in the VoIP phone system, it comes with a high price tag that makes it suitable for large business organizations. The cost of VoIP depends on the total number of employees in a company. One of the primary benefits of using VoIP is it enables you to access all its functions from a computer.
