Your paper is good and the flow of the paper is also clear, but try to organize it,like the structure of sentences,its formating and giving a number to each heading. your explaination about VOIP componets is good and you also explained some topics like quality of services, jitter and so....on but you didn't explain how they are related and try to Use some figure so that it can give a better understanding.
