Hence the objective of this project is to demonstrate that Asterisk can provide very specific functionality as described in this project and allow it to compete with proprietary telephony systems. In the first chapter details the background, objectives and rationale of this study, the second comprised the essential concepts for implementation thereof, in the third chapter describes the technical specifications and project development and in the fourth chapter specifies how work and tests carried out.
