Utilization of Software Exchange in Laboratory Education
Komárek, Milan ; Endrle, Pavel (referee) ; Škorpil, Vladislav (advisor)
The main aim of this bachelor thesis is the use of a switchboard in laboratory exercises. The first section describes the SIP signalling protocol, its components, addressing and messages. In the second part there are designed three laboratory tasks. The first laboratory task is focused on connecting 3CX switchboard and Cisco router using a SIP Trunk. This describes the configuration of the switchboard, Cisco router and IP phones. The second laboratory task verifies the function of data transcoding in a 3CX switchboard. That includes an analysis of voice connection of participants working with a different codec. The third laboratory task tests specific functions provided by the 3CX switchboard.

IP Multimedia Subsystem technology signalling
Čech, Martin ; Stančík, Peter (referee) ; Mácha, Tomáš (advisor)
Aim of this Bachelor´s thesis is to describe singnalization during communication through IP Multimedia Subsystem technology. The first part focuses on describing the technology itself, entities of its architecture and used protocols. Next part deals with creation of a network which will be used for examining signalization during call sessions. This network is created in Ericsson´s Service Development Studio environment. The last part discusses development and testing of client application for instant messaging.

Intercommunication of Asterisk and VCON VoIP PBX
Balon, Jiří ; Říha, Kamil (referee) ; Číka, Petr (advisor)
The main goal of this bachelor thesis was to familiarize with VoIP telephony development and its nowadays utilization. First part of the work includes description of known communication protocols SIP and H.323 architecture and their usage in communication. Next part is dedicated to software PBX Asterisk that runs under Ubuntu distribution of Linux operation system. The process of PBX installation is described there as well as its adjustment for SIP and H.323 for communication within IP net. There is also described software PBX VCON that runs under Windows XP operation system. Beyond the adjustment of the PBXs there is also concrete adjustment of software clients SJPhone and X-Lite that are necessary for communication between individual telephone exchanges. The final chapter is dedicated to the problems of mutual connection (intercommunication) of individual telephone exchanges Asterisk and VCON.

Network services in IMS
Mikulec, Matěj ; Mácha, Tomáš (referee) ; Nagy, Ľuboš (advisor)
This thesis is focused on services that can be used in the architecture IP Multimedia Subsytem. The first chapter describes the main entities in the IMS architecture. The second chapter is focused on services - Presence, Instant Messaging, Push to Talk over Cellular and IPTV. For each service is described architecture and basic signaling. The third chapter describes the various protocols used in IMS, protocol SIP is described in more details. The fourth chapter contains a description of the application environment SDS Ericsson in which was implemented practical part. The fifth and final chapter deals with the IPTV service in SDS and SIP communications with IMS core. Traffic reports are analyzed in each case the client communication with IMS core with integrated tracking of messages passing through the CSCF, HSS and DNS in program SDS. Important findings of the work are summarized in the conclusion.

IMS security solutions
Porubský, Tomáš ; Rášo, Ondřej (referee) ; Mácha, Tomáš (advisor)
In the first part of my master's thesis the network architecture of IMS (IP Multimedia Subsystem) is presented. The database of subscribers HSS (Home Subscriber Server) and SLF (Subscription Locator Function), as well as a SIP CSCF servers (Call Session Control Functions) process a SIP signalization and an AS application server performing services, etc. I focus on the registration of subscribers in the IMS network with a list of transmitted messages and description of each interface that is used in this network. The most important interfaces, which I described here, are Gm, Mw, Cx, Dx and Sh. Then I focused on security in IMS problems, which are divided into categories of access security and network security. After that is the implementation of IMS network in an open source Open IMS Core System considered under the Linux operating system. Here is the problem description from the actual system installation, through the configuration of all necessary elements of the network to the communication party itself. The communication analysis in the initial registration process and in subsequent communications is described. Finally I created laboratory exercises with a focus on the Open IMS Core System, where students learn about architecture and principle of networks based on IMS technology operation, with individual elements necessary for the operation of the network and their configuration. Students also test simple captured traffic analysis.
