Currently all services converge into a Next Generation Network and considering that today the requirements about quality of service are more stringent because of the same user requirements, it is necessary to propose a procedure of QoS to ensure an efficient operation of transporting the most critical services and real time; as the voice, ensuring the reduction of latency, jitter, packet loss and Eco. The CRC (Regulatory Commission of Communications) in Colombia applies the provisions of QoS for they can be used by telecommunications operators and they must be conform to the recommendations Y.1540 and Y.1541 ITU-T (International Telecommunication Union). The aim of this paper is to present a procedure for applying QoS mechanisms in NGN network in xDSL access in order to maintain quality of service in Voice over IP (VoIP), which allows economic and technically efficient provision of VoIP for customer and the telecommunications operator.
