Voice over IP (VoIP) is at the moment one of the most discussed topics in the current network scene. Besides the theoretical interest in network development, there is always the practical relevance which is of high importance for advances in network technology. One major proof, that VoIP research and its technology has a high impact on businesses is the fact that VoIP it is already implemented in a number of companies in the United States of America, UK, Ireland and South Korea, according to Cherry (2005). The following graphic shows the importance of VoIP for companies according to a recent international study conducted by Network Computing.

1. Introduction and brief overview of Voice over IP
Voice over IP (VoIP) is at the moment one of the most discussed topics in the current network scene. Besides the theoretical interest in network development, there is always the practical relevance which is of high importance for advances in network technology. One major proof, that VoIP research and its technology has a high impact on businesses is the fact that VoIP it is already implemented in a number of companies in the United States of America, UK, Ireland and South Korea, according to Cherry (2005). The following graphic shows the importance of VoIP for companies according to a recent international study conducted by Network Computing.
30% of all participants in the study confirmed a current implementation and usage (chart 1: 30% - VoIP is in production) of VoIP technology. This indicates the high investment activity which is currently happening in the field of VoIP. Regan (2005) for example states that the Department of Defense (DoD) of the United States of America established in the beginning of 2005 an over US$ 20 Mil. contract with Nortel Networks to upgrade the current network of DoD to support VoIP services. The main reasons for implementing VoIP are flexibility, control of communication and cost reduction. (Regan, 2005)
To assess these benefits and to evaluate the risks of VoIP, a sound understanding of VoIP’s functionalities and principles is necessary.
