Asterisk PBX System: Introduction

Hi all,

Open source PBX solutions have been in existence for quite sometime. However, the adoption is still low in this side of the world.

A majority of organisations in Nigeria have deployed analog PBX systems with Panasonic systems leading the pack. This is because the cost of implementing the analog solution was lower than the alternatives, then.

However, the market started asking for more than what the conventional analog system offers. This led to some organisations deploying digital telephone systems.

Asides functionality, certain organisations went digital for aesthetics of the phones (and/or "effizy"). Most IP phones are nice looking with brightly lit screens.


The few organisations that adopted digital PBX technology used proprietary solutions like Alcatel Lucent, Avaya, Ericsson and Cisco Unified Communication System.


Certain other organisations have deployed hybrid systems which are mixtures of analog and digital PBX systems.

Open source PBX systems offer the benefit of the proprietary systems without the attendant high cost of implementation.

Our case in point for this blog is not the low cost solution but the FREE solution.

Free products, most times mean something incomplete and inadequate. However, Asterisk offers enough functionalities to meet most business and private telecommunication needs

Currently, the most popular open source PBX system is Asterisk. http://www.asterisk.org/support/features

In subsequent posts, I shall review the functionalities of the Asterisk PBX system and do a comparison with proprietary systems.

I shall also give an overview of design scenarios for the system.

Thanks for reading!
