VoIP and Conventional PABX together based on Open Source Asterisk

Abstract

The modern business activity can not avoid implementation of computer and communication. Cost and efficiency is an important factor as one of main consideration. Refer to the technology progress, convergence between computer and communication is very interesting. Refer to above situation, Gunadarma university considered to implement VoIP in the organization.

The main problem is cost of communication and high mobility of person. Considerations of cost based on some factors such as budget of investment, cost of operational, budget of expandable, first implementation risk, operational risk.

In depth consideration by looking for some factors were conducted. The result of consideration is to implement Asterisk open source software. In this paper, we will talk the background of VoIP in section one. Section two will discuss consideration of choosing Asterisk open source software and the design which is used for Gunadarma university based on current system by implementation Asterisk. Cost of communication is expensive Gunadarma has many campus location No of talk is high, there are 1,000 lectures and 25,000 students Need an economic, appropriate quality of solution for communication VoIP is a candidate, how to implement Asterisk open source to fullfill the demand
