Tato práce se zaměřuje na práci s pobočkovou ústřednou YATE, popisuje její konfiguraci od prvotní instalace, přes základní nastavení a popis jednotlivých protokolů. Dále je vysvětlen způsob registrace uživatelů, syntaxe pro definování volacího plánu včetně příkladů použití. Jsou demonstrovány doplňkové služby jako přehrávání a záznam audio souborů či vytváření konferenčních místností. Praktickou částí této diplomové práce je připojení počítače s nainstalovanou ústřednou Yate k ústředně Asterisk včetně volání mezi ústřednami a popis definování jednotlivých trunků. Dále jsou vytvořeny dvě vzorové úlohy pro potřeby předmětu Telekomunikační a informační systémy pro bližší seznámení studentů s principy fungování a nastavení pobočkové ústředny Yate. Veškeré konfigurace jsou prováděny výhradně pomocí konfiguračních souborů. 1. PBX YATE Yate (Yet another telephony

    Annals of the University of North Carolina Wilmington Master of Science in Computer Science and Information Systems GNU RADIO AND THE USRP AS A SOLUTION FOR REMOTE EMERGENCY MONITORING Douglas Casey Tucker A Capstone Project Submitted to the University of North Carolina at Wilmington in Partial Fulfillment of the Requirements for the Degree of Master of Science Department of Computer Science Department of Information Systems and Operations Management University of North Carolina at Wilmington 2009 Approved by Advisory Committee Accepted By _______________________________ Dean, Graduate School Abstract GNU Radio and the USRP as a solution for remote emergency monitoring. Douglas Casey Tucker, 2009. Capstone Paper, University of North Carolina at Wilmington. Software-Defined Radio (SDR) is a field that has emerged to solve the problem of interoperability between differing radio frequency (RF) communication standards. Instead of requiring different hardware for each waveform as in traditional analog radio, SDR attempts to provide a more hardware-independent solution by moving the software closer to the antenna. In this document the author presents the case of an information providing company whose goal is to expand into remote locations, the evolution of its operations from low-tech to high-tech automated information systems, and its interest in a particular application of SDR in conjunction with streaming audio and Voice over IP (VoIP) services. 2 Table of Contents 1.

    OpenBTS for dummies Axelle Apvrille, Fortinet January 15, 2013 Abstract This document is to be seen as a guideline or a collection of notes for newbies to OpenBTS who struggle to get it working, or are lost in the wiki pages and wonder where to start. Mostly, I detail here how I got it to work on my side, from step to step, with answers I found to a few issues I faced or my understanding of the problem. I am very (very) far from being an OpenBTS expert. So, please feel free to send in corrections, and also understand that I am probably unable to help you on your specific OpenBTS issues :( If you need some more help, your best choice is certainly to read (and read again) the OpenBTS wiki [Ran], the user manual [Netc] and to subscribe to the mailing-list [ML].

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The Session Initiation Protocol (SIP) is a multimedia signalling protocol that has evolved into a widely adopted communication standard. The integration of SIP into existing IP networks has fostered IP networks becoming a convergence platform for both real- time and non-real-time multimedia communications. This converged platform integrates data, voice, video, presence, messaging, and conference services into a single network that offers new communication experiences for users. The open source community has contributed to SIP adoption through the development of open source software for both SIP clients and servers. In this paper, we provide a survey on open SIP systems that can be built using publically available software. We identify SIP features for service deve- lopment and programming, services and applications of a SIP-converged platform, and the most important technologies support- ing SIP functionalities. We propose an advanced converged IP communication platform that uses SIP for service delivery.
