The primary aim of this paper is to present a new application which is at this moment the only open source real-time VoIP quality monitoring tool that supports IPv6 networks. The application can keep VoIP system administrators provided at any time with up-to-date voice quality information. Multiple quality scores that are automatically obtained throughout each call reflect influence of variable packet losses and delays on voice quality. This article analyses the E-model based methods used in the application to estimate voice quality and the technique of obtaining real-time call quality scores. The example quality monitoring results are presented in several diagrams, interpreted and compared to the PESQ-based reference measurement results.
