In the last few years one of the most interesting questions in IT world is that of convergence between data and voice networks. This procedure cuts down overall expenses of implementation, usage and support of a telephone network, as the expenses of other telephone. Beside the procedures that are prerequisite for the realization of this concept (e.g. ensuring the quality of the transferred voice), it is necessary to ensure the security of that traffic from various threats inherited from data traffic. This paper is about preventive protection of voice traffic transferred through a converged data/voice network.
