This paper introduces a novel method of approximate calculation of delay in voice over IP systems. The proposed method relies on mathematical operations like interpolation and integration to produce a continuous function. This continuous function shows the delay in different times. The paper shows a detailed example of applying this method successfully to a sample call. The resulting delay function can help in better understanding of the variations of delay in different times and how it is affected by network load.
