Introduction The present document is intended to fill a gap in a field where the industry has expressed an urgent need for standardized objectives. Based on the assumption that v
42、oice over IP services with the goal of users being satisfied or even very satisfied with the overall voice communication quality, the present document provides initial guidance on voice quality related parameters and respective objectives for interconnected networks. The present document forms part
43、of STQs roadmap with respect to quality aspects of NGN. ETSI ETSI TR 102 775 V1.6.3 (2014-10) 71 Scope The present document provides guidance on the quality parameters that need to be considered at the Segment-connection of Voice over IP (VoIP) services and provides guidance on objectives for these
44、parameters. Inside the TISPAN NGN overall architecture (see figure 1), the present document considers only the transport layer.
