Abstract [en]

As information can be sent via various mediums through different channels,  visual or vocal communication can also be carried out though various channels such as public switched networks (PSTN) and packet based switched systems which are commonly known as voice over Internet protocol (VOIP). This particular study emphasizes on voice over Internet protocol and its various aspects.

 

Codec is the most important aspect in VOIP communication there is variety of codecs available. In order to have right quality of voice the right codec must be selected. There are various other factors such as bandwidth and right technical infrastructures which are also present and which must be addressed in order to have a better quality of voice over VOIP.

 

Mostly, VOIP is used in companies where a huge volume of voice calls is needed, especially in call centers which deal in offshore sales and support projects. The main factor which make companies and other users interested in  VOIP is the financial aspect as, VOIP cuts costs significantly. Every mode which may be utilised for voice communication has its own advantages and disadvantages so user can chose the mode of communication according to what is required.

 

In order to provide the financial and technical advantages of VOIP, various previous studies have been studied, information has been collected from different call centers and a network is simulated using OPNET MODELLER in order to evaluate the performance of VOIP codec as the codec is basically coder as well as decoder, hence it is the basic aspect in order to have a better quality of services (QOS) and quality of voice (QOV).
