The new trend in Quality of Services (QoS) encompasses the non-utilization QoS indicators and parameters, in addition to traditionally known in-service QoS parameters. This is due to the fact that customer satisfaction is the dominant factor in achieving QoS requirements. For this reason, in 2012 the ITU published its new recommendation, ITU-T E.803, to cover the non-utilization QoS parameters. In spite of its importance to the current situation of developing countries, the complete deployment of that recommendation may face some complications.
