Abstract

VoIP, Voice over Internet Protocol is one of the emerging and bleeding edge technologies that have in most cases sorted out the budget problems for the transmission and reception of voice communications. Indeed it is to use the Data Network infrastructure (Packet Switching Network) for the transmission and reception of voice calls. Though, people do prefer to use circuit switching network as it gives a dedicated path between end users that results in a crystal clear voice quality. Also the Digital communications “Modulation for the Transmitter end” and “Demodulation for the Receiving end” is involved (Digital Signal Processing to provide phenomenal voice quality) but no one can regret a fact that is; occasionally it becomes too expensive for the organization to provide dedicated paths to all employees. A promising solution is yes of course VoIP but the deployment of this technology introduces issues like Voice Quality, Jitter/ Delay, Quality of Service, Denial of Service etc. which is a challenge. In order to deploy VoIP communications in an existing Network it is very crucial and important to do proper planning and to analyze the network critically and justify whether it the Network is ready to cope with the VoIP services, as it can cause serious effects to the Network in case it is over burden. After doing that to assess and then evaluate by testing the network. This research is a case study based on B&A, A spy agency that has faced problems in the future regarding to call management and expansion. This research will cover the design and implementation of VoIP simulated in OPNET.
