3 Major Types and Features of Office Phone System

An efficient office phone system streamlines good communication between the organization and customers.

Time and again, you will hear an expert claim that the communication sector has come of age. These bold statements show that technology has rapidly transformed the way individuals and businesses communicate in their daily lives. The number of mobile devices in the world has so far exceeded the world’s population. Plus, most people use mobile phones as their preferred means of communication. But for professional conversation an advance office phone is compulsory.

The smartphone industry has the greatest impact on how businesses communicate internally and externally. Most companies are looking to develop smartphone applications that mimic their business models. These applications are intended to make communication more efficient inside and outside the business environment. Every businessman needs to communicate frequently with various stakeholders. Office telephone systems are essential to address this complex nature of telephony in the business environment.


What is an Office Phone System?

The business phone system is a network of software and hardware-based phones that enables company employees to efficiently manage incoming and outgoing calls. It’s very different from your home phone system. Both small businesses and large businesses can use the office telephone system. Depending on the size, different systems may be suitable for different organizations.

Types and Features of Business Phone System

There are three main types of office telephone systems:

·Key System Units (KSUs)

Out of the three phone systems, this phone system is the simplest. A service technician is required to install the Key System Unit (KSU) (the hardware system installed in the site cabinet). The push-button of this phone system is connected manually to all telephone lines. The user presses a button to make a call. The button lights up to indicate the line in use. There is also a KSU portable system called KSU-less. The KSU-less unit is on the desk.

The box has a socket for connecting a certain number of telephone lines and a jack for extensions such as fax machines and answering machines. The push-button telephone system includes basic analog features such as hold keys, speakerphones, and intercoms. Because the system is landline-based, touchphones can only support a limited number of phone lines and may be suitable for small offices.

Also, telephone service professionals have to work in the field, which is expensive to set up and maintain. When it comes to supporting business communication, KSU is limited. In addition, the telephone company has not upgraded these systems. Consequently, as your business grows, you will face demolition and replacement situations.

·Private Branch Exchange (PBX)

PBX systems are suitable for growing and expanding your business. The PBX system for small business consists of two components: the phone set and the PBX. Therefore, it is also a virtual telephone system.

It allows incoming calls to be automatically routed using a programmable attendant device. There are also other unique features such as call transfer, call hold, and custom greetings. PBX system for small business has more features than the KSU and will work without electricity for some time.

·VoIP Phone System

VoIP refers to Voice over Internet Protocol. Another VoIP term that engineers may use is IP telephony. VoIP is the process that allows voice messages and other types of communications to be sent over the Internet. Because of the many benefits that VoIP PBX offers, many companies are switching to the Simple Legacy Telephone Service (POTS). So, this thing is also known as the Public Switched Telephone Network (PSTN).

A VoIP telephone system converts a voice signal into digital information in a data packet and sends it over the Internet through a router. VoIP PBX calls are Internet calls or other types of communications that travel over the Internet. Such as text, email, and chat. VoIP calls have all the options found on a multi-line office PBX, including voice mail, call transfer, call waiting, caller ID, and conference calls.


Communication is essential to the success of your business. But that doesn’t mean you’re damaging your company’s reputation for working hard to reach more customers. With a business phone system, you can do both without compromising your professionalism.

Develop business applications, but try to reach your customers only through a flexible office phone system. This improves reliability, ensures secure communications, prevents fraud, and saves business costs by avoiding unnecessary overheads in lieu of phone and cross-border charges.
