IP-PBX Origination

How did IP-PBX originate from PBX?

By: Adom Brown,

PBX (Private Branch Exchange) is a switching station for telephone systems. The phone line associated with it is analogous to “the structure of a tree with many branches”. Trunking is the concept underlying PBX by which this communication system can provide network access to many clients by sharing a set of lines or frequencies instead of providing them individually. It switches connections to and from those branches, thereby linking the phone lines.

The companies use PBX for connecting all their internal phones to an external line. In this way, they can engage only one line and have many people using it, with each work desk having a phone device with different number. This number is termed as an extension. A person calling from outside, can connect to the organization using a single number, but he might ask for an extension in order to be directed to the person he is targets, actually.

Rise of IP-PBX to overcome the failings of traditional PBX:

A PBX that transfers the voice over Internet Protocol in the form of data packets is termed as VOIP PBX.

The crucial benefits that an IP-PBX brings around as compared to traditional PBX systems are easy installation, scalability and many fascinating features, that too at a tempting price.
IP-PBXs are more software based than their predecessors and so maintenance and upgrade costs are considerably reduced. The work in this is simple because of a web based control panel which works on programmed sequence and can incorporate changes quickly.

Adding, moving and removing users to a telephone system can be very costly in other systems, but with IP-PBX it is as cost-effective as it is easy. If you want to move an office you just unplug the phone from the internet and plug it in at the new location, the phone works exactly the same at the new location, with the same extension number, same everything except location. Users can transparently log in the system through any phone in the network; without however losing their personal profiles and configurations with the unified communication feature.

IP PBX Services

Up to now, PBXs have been a business luxury that only huge companies could afford. Now, with IP-PBX, medium-sized and small companies can benefit from its effective functionalities. The types of services have been broadly classified into:

Real PBX services

In the real PBX, the hardware equipment resides on the company’s premises but the service provider takes care of the network and maintenance part.
True, that in this the initial investments incur some money into hardware and software, but the return and benefits are considerable in the long term, both operationally and financially. It is best suited for large businesses.

Virtual PBX Hosting Services

Virtual PBX is also referred to as “hosted PBX”. In virtual PBX, the hardware and software requirements, the set-up, maintenance is all looked after by the service provider itself. You just have to select a provider and subscribe for the service plan on monthly or annual basis and they install and configure it for its first use in no time. It gives you the freedom of using the features of IP PBX without spending much on maintenance. It is mainly suited for SMB (small and medium businesses).

So, choose the best suited IP PBX plan and provide a makeover to your business phones.
