The Difference between PBX and VoIP Phone Systems

by Daniel Stockman, i-Tech Support, Inc



Have you ever had the experience of calling an office, asked to talk to a particular person, and got your called transferred to that person’s extension?

Or you simply called a company, then dialed the extension, and gotten directly in touch with the concerned person without having to talk to an operator?


In the modern world, you must have!


Have you ever wondered how this is done? What is the science behind it?

If you have ever worked in a technologically advanced office, you must know that all the phones in a company are interconnected. This is exactly what we call a ‘telephone system’.

Depending upon the numbers of telephones that are interconnected, a telephone system can be simple (mostly in case of small businesses) or complex PBX system (in case of medium to large scale businesses).

With a phone system in place, users can benefit from amazing features of advanced telephony. These include call transfer, call handling, call accounting and metering, sending voice messages (both shared and private) and conference calling to name a few.

What Is a PBX Phone System And What Are Its Advantages?

An acronym for Private Branch Exchange, PBX is a system that is comprised of both hardware and software that jointly work to make a business’ communication system efficient and easy to use.

It allows businesses to manage and control not only the internal communication, but also the outgoing and incoming telephone calls.

With a PBX system in place, a business can save a hefty amount of money. This is because in a PBX phone system, not all telephones in an office are directly connected to the public telephone network. Due to this, the calls that are made within the organization are not directed by the telephone company, rather by the PBX and hence, are not charged. The telephone company only charges for a small number of lines through which external calls are made.

In simple words, a PBX splits one single telephone line into several internal telephone lines and assign 3 to4 digit numbers, known as ‘extensions’ to each.

What Is VoIP And What Are Its Advantages?

Have you ever used Skype?

You must have, unless you have been living under a rock!

But, do you know that it uses the VoIP technology and hence, played the key role in making it the most successful of last decades’ technologies?

It is highly likely that you do not, unless you are related to the field of information technology!

A short form of “Voice over Internet Protocol”, VoIP is a technology that has given an entirely new definition to the communication process.

Through this technology, people can use internet for making calls. Using internet to get in touch with your co-workers, partners and clients means you won’t have to pay large sums of money, each month, in terms of telephone bills. The only thing you want to make use of VoIP technology to communicate is an internet connection that is reliable and has a good speed. Isn’t it amazing?

The significantly low cost of VoIP technology based telephone systems is the biggest reason that more and more people are replacing the traditional phone systems with the ones that make use of VoIP technology.

This latest technology is alternatively known as Internet Calling, Internet Telephony, and IP Telephony. ‘
