چکیده

Monitoring call quality in a Voice over IP (VoIP) environment has great importance to collect information about those calls on the network. Packet loss on the network and de-jitter buffer, delay and subjective speech evaluation using the E-Model will enable the manager to verify the quality of calls. This article proposes the development of an agent to implement objects with statistical data about quality of call evaluation in a VoIP environment Key-words: VoIP, Quality of call, Monitoring, Statistical data.

Developing Fuzzy Models for Estimating the Quality of VoIP

This paper presents a novel method for modeling the one-way quality prediction of VoIP, non-intrusively. Intrusive measures of voice quality suffer from common deficiency that is the need of reference signal for evaluating the quality of voice. Owing to this lack, a great deal of effort has been recently devoted for modeling voice quality prediction non-intrusively according to quality degradat...
