Pokročilá komunikační řešení v IP telefonii

Abstract

The work deals with the topic of advanced communication service that can be offered in a modern private branch exchange. Mainly it is focused on open and free distributable applications. The emphasis is placed on technology WebRTC and sipML5 of client in cooperation with private branch exchange Asterisk. The practical part describes the configuration of private branch exchange Asterisk to work with sipML5 client and then analyzing the connections with an existing (building) solution. It contains a detailed analysis of the connection either in connection with the present commonly used SIP client or another sipML5 client through the web interface. In this work is also performed analysis of the connection, for which I used a packet analyzer Wireshark. Thanks to the detailed documentation about the configuration of the virtual machine it is possible to reconstruct project easily and to build on it in other projects and works.
