Taking about PBX or Private Branch Exchange definition, it refers to an analog telephone system used to switch calls between users and local lines in an enterprise over a local line. In order to facilitate internal communication inside an organization, the PBX system is a must.

— Generally, a PBX is a piece of hardware used to switch and route calls. It helps to manage the incoming and outgoing calls of an organization. Also, users can communicate externally apart from inside communication. 

And that’s not all, a PBX can help an organization to avoid additional costs of separate phone lines. How? Because a PBX allows the users to share multiple phone lines. 

The endpoints of a Private Branch Exchange are connected to a switch. The endpoints of the switch are connected to a router while the other ports are connected to the endpoints of IP phones. 

Although the switching system handles a small amount of traffic, a large number of calls are exchanged through it. Among many features, here are some mentionable features of PBX –

  • Enable auto-attendants when someone is waiting for a call.
  • Enable Unified Communications or UC router – both wireless and wired.
  • Terminates telephone trunk lines.
  • Handles inbound and outbound calls.
  • Automatically handles inbound calls.
  • Ingrates with Customer Relationship Management (CRM) systems.
  • It features Interactive Voice Response (IVR) for call monitoring.

Components of Private Branch Exchange

Types of Private Branch Exchange

In general, there are 2 types of Private Branch Exchange – Traditional PBX and IP-based PBX. These 2 general types of PBX are further categorized into 2 types. 

Traditional PBX

  • On-Premise PBX
  • Hosted traditional PBX
IP Based PBX

  • On-Premise
  • Hosted IP PBX

What is IP PBX

The traditional PBX has limitations to connecting with a certain number of trunk lines and internal device extensions. Keeping that in mind, the IP PBX was introduced to keep up with the technological demands.

— Nowadays, IP PBX includes both hardware and software. And that’s not all, it connects with various communication devices like hubs, switches, routers, telephone adapters, telephone sets, and more.

IP PBX usually works in VoIP telephony systems. It switches calls between VoIP users. Unlike the traditional PBX, it not only works with telephone lines and switches but also with an internet connection to channel calls. As a result, it ensures secure internal communication for any business by connecting extensions to the Public Switched Telephone Network or PSTN.

The benefits of IP Private Branch Exchange

  • The first and foremost benefit of the IP PBX is cost-efficiency. It is a better cost-effective solution than the traditional PBX. 
  • It is very easy to install and configure IP PBX in comparison with the proprietary phone system. 
  • It offers better scalability, better management, and enhanced features.
  • Most IP PBX is software, which makes them easier to maintain and upgrade than the previous hardware-based PBX.
  • An interactive web/GUI offers a user-friendly interface.
  • Eliminate vendor lock-in.
  • Eliminate phone wiring.

Drawbacks of IP PBX

  • IP PBX may offer an API to integrate with CRM softwares. However, the cost is sky-high, especially when the CRM vendor doesn’t use your particular PBX.
  • If you are running a premise-based IP PBX business, make sure you have a team of skilled customer service representatives. As the industry experts say – 

“88% of consumers prefer dealing with a company with strong customer service rather than one with the hottest, most innovative product offerings.”

A hosted PBX is a cloud-based, virtual PBX phone system that provides secure and reliable phone service for a particularly owned and operated business or organization over an internet connection, where there’s no need to operate a personal call controller or server.

Third-party service providers will take care of building and hosting the PBX system on their premises. As a customer, you can stay out of the hassle for further maintenance. One can connect hosted PBX to a client’s telephone system through the internet.

All it requires is to purchase IP phones. There are combo packages offered by the hosted VoIP service providers that include server, dialer, and Softswitch altogether.
