Reading time: 4 minutes

Your business wants to install a PBX system for your office but doesn’t know where to start or what to consider? Today’s article will define a PBX system and answer your questions. Let’s follow along!

Understanding the definition of a PBX system

Simply put, a PBX system is an automatic telephone switching system within a private business. It’s also known as a switching system that allows endpoints to communicate with each other and make external calls using a number of subscriber lines from various network providers.

Currently, there are two types of PBX systems in businesses:

  • Analog PBX (Traditional PBX): This is a public switched telephone network. When a business registers a number, the network provider will directly lay the customer’s trunk line. From there, the business connects to the analog PBX to configure and assign extensions.
  • Virtual Call Center (VoIP Call Center): This is an advanced voice and audio service using VoIP technology on a cloud computing platform to improve customer service quality, connect calls, and reduce call costs to the lowest possible level. Combined with CRM (customer relationship management) tools, it enhances customer service quality and optimizes sales closing through calls.

Things to Consider When Installing a PBX System for the Office

Choosing a PBX System

If your business is currently using an analog PBX, consider using a virtual PBX to enhance its functionality and meet your needs. However, if you want to reuse your existing system, consider using a VoIP Gateway to convert analog signals to VoIP.

Determining Your Office PBX System Needs

Each business will have different needs for a PBX system. Sometimes, businesses only need basic calling, while others require additional features such as CRM integration, human resource management, customer management, etc. Furthermore, businesses must determine the number of users to build a suitable system.

Choosing the Right Phone Number

After determining your needs, businesses need to choose a suitable phone number. These are the two most popular phone numbers currently:

  • 1900 number
  • 1800 number

Choosing a terminal device

Terminal devices help receive and make outgoing calls from the call center. Choosing the right device will improve productivity and call quality. If you frequently travel, a softphone is recommended.

Equipping a stable internet connection

An internet connection is a mandatory requirement for the call center to operate. To ensure stable calls, businesses should equip a dedicated connection to prevent external devices from accessing it. In addition, businesses should back up 1-2 network connections in case the main connection fails.
