The term “PBX,” for private branch exchange, is in most cases simply a synonym for business phone system.
Internet Protocol PBXes, or IP PBXes, are phone systems that connect calls via the internet rather than the traditional phone network.
We’ll explain the core features and benefits of IP PBX systems. We’ll also take a look at some of the key factors that businesses need to consider when investing in a new phone system.
Here's what we'll cover:
The term PBX itself is a relic from the early-20th Century, as we explain in our extended definition.

Broadly speaking, a PBX’s function is to unite all the separate phone extensions that a business uses so they can function together as one system. Specifically, PBXs:
PBXs have been performing these same tasks for decades. As the internet increasingly takes over the function of the traditional phone network, however, the capabilities and features of PBXs have also evolved.
VoIP, or the Voice over Internet Protocol, has brought many changes to all aspects of business telephony—PBXs included. With VoIP, it’s now possible to send calls over an internet connection, as opposed to paying for traditional business phone service.
In order to reap the benefits of VoIP, you need an IP PBX rather than a traditional PBX, as an IP PBX system can connect directly to the internet. Older PBX systems, on the other hand, connect to analog or digital phone lines.
There are devices known as gateways that allow you to use VoIP service with an older PBX system. If you’re replacing your system, however, it makes much more sense to simply invest in an IP PBX.
IP PBXs exist in several very different forms. Although they all perform similar functions, there is no strict definition of the term. An IP PBX can refer to:
|Hardware-based on-premise systems||Specific on-site hardware devices that look much like typical rack-mounted servers.|
|Software-based on-premise systems||PBX software running on a computer outfitted with phone connections.|
|Virtualized on-premise systems||“Virtual machines” installed on commodity hardware running a virtualization platform such as VMware.|
|Cloud-based systems||Systems hosted by a VoIP provider in the provider’s data center rather than a server on your business’s premises, delivered as a service over your Internet connection.|
Traditionally, PBXs were very expensive to purchase and maintain, and th
