VoIP training course description Convergence of voice and data is now a common place mainstream technology. Our Voice Over IP course investigates the characteristics of voice transmission and then studies the impact on IP networks. Practical sessions with soft phones, hard phones and gateways allow the students to see all aspects of VoIP. Network analysers are used to study packets on the wire. What will you learn Describe the issues of voice and data convergence. Describe techniques, which can be used in IP to provide low uniform delay. Evaluate VoIP technologies. Design data networks, which will support voice. VoIP training course details Who will benefit: Anyone working in the field of networking or telecommunications. Prerequisites: TCP/IP foundation for engineers Intro to data communications & networking Duration 3 days VoIP training course contents What is VoIP Voice over IP, brief review of IP, brief review of telephones and voice.
