One of the options that telephonic systems have, in order to optimize the required bandwidth, is to migrate to statistical multiplexing systems. These multiplexing schemes also allow the convergence with current data communications systems. This work is based on the interconnection of telephonic systems through the data network using digitalization and voice compression techniques. The optimization of the resources is achieved using the voice compression standard of 8 kbps instead of the 64 kbps standard, thus introducing differentiated services in IP networks. The performance of the voice packets is improved in terms of delay and packet losses. The results presented here obtained by means of computer simulations using COMNET. Real telephonic traffic information acquired for several months at the UABC was used. This allowed the consideration of effects such as: busy hours and variable call duration. The performance of the system was evaluated, obtaining very satisfactory results in terms of resources utilization.
