Design of Monitoring System and Conference System on NTP VoIP Platform

摘要

This paper introduces an experiment SIP-based VoIP platform and its services. We first describe the major components of the SIP-based VoIP platform. Based on the VoIP platform, the researchers can develop and deploy their applications and services. In this platform, we develop and deploy two systems: VoIP monitoring system and conference system. The monitoring system is deployed to provide call detail records and lawful interception for the platform administrator. The conference system is deployed to provide audio and video conferences for the platform users. In this paper, we provide detailed message flows to show how the monitoring system and the conference system work.
