Issues of Implementation of Voice Over IP With Quality of Service: An Overview
This paper explores various aspects regarding to the implementation of voice over Internet Protocol (IP) with Quality of Service and gives a detailed insight into this. Internet telephony utilizes the Internet medium to transfer audio between two or more clients in real-time, thus allowing the clients to make conversations simultaneously on telephones. Converged voice and data using a packet based transport offers flexible, scalable, and cost efficient services. Emphasis is put on the efficient voice communication over the IP network so that Quality of Service (QoS) is maintained. Packet voice quality issues and strategies for minimizing the packet loss are described and implemented.
