On December 3, 2021, a guest lecture for students of the Department of Artificial Intelligence Technologies was held at Karaganda Industrial University. The guest of the university was the head of the production communications section of JSC «ArcelorMittal Temirtau» Evgeny Kuznetsov.

The lecture devoted to the basics of IP telephony was attended by more than 50 students of the Department of Artificial Intelligence Technologies, who study in the educational programs «Automation Systems Engineering», «Artificial Intelligence Technologies», «Software Engineering», as well as specialties «Computer Engineering and Software» and «Automation and Control».

IP telephony (pronounced «IP telephony») – telephone communication via IP protocol. IP telephony refers to a set of communication protocols, technologies and methods that provide traditional telephony dialing, dial-up and two-way voice communication, as well as video communication over the Internet or any other IP networks. The signal is transmitted digitally over the communication channel and, as a rule, is transformed (compressed) before transmission in order to remove information redundancy and reduce the load on the data transmission network.

During the event, the lecturer introduced the students to the history of the development of telephone communication in the world, the main differences between IP telephony and traditional telephony, the principle of operation of the IP network, the features of the use of operational dispatch communications in production.
