  • Intra/Tailored

This seminar presents an overview of the main protocols, the standardization, the voice quality and bandwith, the migration, the performance and the security of voip technologies, and introduces you to the major components of voice over IP networks. On all these topics, the main solutions are detailed and illustrated with case studies.


After Engineering studies in France and in the US, he worked on telecommunications engineering projects in France, US and Chile. He served as CTO for OpenPattern a french telecommunications company developing an OpenHardware FPGA-based router-board. He is currently working for a Linux-based VoIP company managing the development of the XiVO IPBX OpenHardware appliance. He is the author of numerous telecommunications books among them a reference book about PowerLineCommunications.
