Abstract :
Voice over IP offers important opportunities for the telecommunications market to deploy more advanced services, but it must overcome many obstacles. Users expect toll-quality voice, which calls for end-to-end quality of service (QoS) - a challenge for IP service providers. To make VoIP attractive to end users, the only feasible and directly implementable alternative is to deploy an efficient mechanism within the endpoints. To that end, the authors propose the scalable, modular, call quality monitoring and control framework for maintaining voice quality at acceptable levels over networks that don´t offer QoS guarantees.
