Abstract:	Diplomska naloga opisuje storitev za snemanje pogovorov lokalnega naročnika telefonske centrale pri podjetju Iskratel, d. o. o. Storitev za snemanje pogovorov lokalnega naročnika telefonske centrale naj bi bila sposobna narediti telefonski klic na poljubno snemalno napravo, administracija storitve pa naj bi potekala izključno preko upravljalnega vozlišča telefonske centrale — storitev spada med dopolnilne storitve lokalnega naročnika telefonske centrale. Razvoj storitve za snemanje pogovorov lokalnega naročnika telefonske centrale je pomenil implementacijo dodatne funkcionalnosti v obstoječi produkt SI2000 iCS proizvajalca Iskratel. Delo je vključevalo vse faze razvoja storitve za snemanje pogovorov lokalnega naročnika telefonske centrale, tj. od ideje do končne izvedbe. Storitev za snemanje pogovorov lokalnega naročnika telefonske centrale sem razvijal v programskem jeziku SDL. Posebna pozornost je bila namenjena preverjanju delovanja celotnega produkta SI2000 iCS oziroma potrjevanju, da implementacija nove funkcionalnosti za snemanje pogovorov lokalnega naročnika nima negativnih stranskih učinkov na delovanje ostalih funkcionalnosti produkta SI2000 iCS. Rezultat naloge je delujoča rešitev, ki omogoča snemanje klicev lokalnega naročnika na poljubno snemalno napravo, ki je zmožna sprejeti telefonski klic po eni izmed signalizacij, podprtih v telefonski centrali (npr. analogni, H.323, ISDN, SIP ...). Pogovori nadzorovanega lokalnega naročnika se snemajo stalno ali na zahtevo lokalnega naročnika telefonske centrale. Nadzor lokalnega naročnika aktivira administrativno osebje telefonske centrale, v primeru snemanja na zahtevo pa lokalni naročnik telefonske centrale med zvezo.

Title:	RECORDING CONVERSATIONS FOR ENABLING LEGAL INTERCEPTION IN TELECOMMUNICATION NETWORKS
Abstract:	Diploma thesis describes the development of the service for recording conversation of local subscriber of telephone exchange manufactured by Iskratel d.o.o. . Service for recording conversation of local subscriber of telepohone exchange should be capable of making telephone call to various recording device, while administration of service should be done exclusively over using the managment node of telephone exchange. The service implemented is one of supplementary services of local subscriber of telephone exchange. Development of the service for recording conversations local subscriber of telephone exchange actually meant implementation of additional functionality to existing product SI2000 iCS producer Iskratel. The work included all phases of development of the service for recording coversation of local subscriber of telephone exchange from the idea to final implementation. I was developing the service for recording conversations of local subscriber of telepohone exchange in programming language SDL. Special attention payed at verification activities of entire product SI2000 iCS functionality and confirmation that implementation of new functionality for recording conversation of local subscriber of telephone exchange did not have negative side effects on performance of others functionality of product SI2000 iCS. The result of work is a working solution, that allows recording conversation of local subscriber on any recording device, that is capable of accept telephone call over one of suported signalling protocols in telephone exchange (e.g. analog, H.323, ISDN, SIP, ....). Conversations of monitored local subscriber are recordered permanently or occasionally upon the request of local subscriber. The monitoring of local subscriber is activated by the administrative personnel of telephone exchange while in case of an occasional recording the local subscriber of telephone exchange can issue a corresponding request.
