Companies that have increased number of inbound and outbound calls are not rarely met with under-organized way of monitoring them. This paper presents a system based on information technologies that enable the management of telephone calls. The idea is to store a phone call with his relevant data, and to manage them. In addition to telephone calls as relevant information are people within the company who are participant, this data is also stored and enables the management of the same. The paper describes the technologies used in the development system which is made up of two layers, namely the application and data. Each layer can, and must not contain more technology that mutually harmonized action form one unit. This system allows the reporting within the application layer, which facilitates management decision-making. The result is better management of telephone calls, better decision management and customer satisfaction, which is shown in the application of such systems, in which I was able to convince. I also like the visual representation of the application layer, and I hope that he will carve an unforgettable memory of the users of this system. In the description of technologies that are used to make the system I carried out amount of information about technology. Explained the advantages and disadvantages of technology, and the reason for selecting technology. In this paper, I also carried out description of the problem with which I met, and finally a solution that is implemented in the development of the system. The largest chapter is the chapter that describes the application itself, there is described the use of applications by users, as well as all the functionality that are made. Finally, in conclusion, I made a few concluding sentences of the entire work.
