Summary

This course is directed towards the students of study program Information and communication technology. The aim is to acquaint students with technologies and standards of voice transmission in IP network with communication protocols H.323, SIP, MGCP and with elements enabling an implementation of voice services in IP network. A significant part is focused on area of Quality of Service. Laboratory works are oriented on protocol analyzing and students can choose semestral project from three themes based on open source VoIP solution as Asterisk, GnuGK or OpenSER. Communication standards are been already formed with pursuit to network design with integrated service which are able to transfer a data, voice or video. The next generation networks are using in considerable amount these techniques which are called as Voice over IP and VoIP is the significant direction in next evolution of communications.
