VoIP communication QoS analysis system

In the last years we are witnessing a merging trend towards unified communication systems over IP protocols from desktop to handheld devices. However, current IP communication protocols are based on best-effort services with limited or no QoS control. The lack of cost-effective or power-aware QoS strategies is felt negatively directly by the end user in terms of both communication quality and increasing costs. Therefore, in this paper we try to describe the proposed system, build for monitoring and analyzing both online or offline call related data in order to extract QoS information from end user perspective.
