DEVELOPMENT OF A TELEPHONY APPLICATION IN ASTERISK

V diplomskem delu opisujemo izdelavo telefonske aplikacije s pomoÄjo naroÄniÅ¡ke telefonske centrale IP Asterisk, ki Älanom Laboratorija za mikroraÄunalniÅ¡ke sisteme omogoÄa prijavo oziroma odjavo na telefonih v razliÄnih prostorih. Prav tako lahko vodja laboratorija ob vsakem Äasu preveri dosegljivost kateregakoli Älana. Vsi Älani so dosegljivi s strani drugih zaposlenih na TehniÅ¡kih fakultetah in lahko jih tudi sami kliÄejo. Za testiranje delovanja aplikacije potrebujemo ustrezne telefone oziroma programske telefone. Vzeli smo, da je uporabljen signalizacijski protokol SIP in da so telefoni povezani v omrežje IP. Delo najprej opisuje namestitev telefonske centrale kakor tudi podatkovne baze. Nato se osredotoÄimo na konfiguriranje terminalov, podatkovne baze in pisanje Asteriskovih konfiguracijskih datotek. Težave, ki smo jih ob tem imeli, in njihove možne reÅ¡itve opiÅ¡emo na koncu dela.In this diploma thesis, we describe the development of a telephony application with the help of IP private branch exchange Asterisk, which allows members of the Microcomputer systems laboratory to log in or log out on the telephones in different rooms. The head of the laboratory can at any time verify availability of any member. All the members are reachable to other employees of the Technical faculties, which they can also call. To test the application we need phones or software phones. We assumed the use of signaling protocol SIP and that the phones are connected to an IP network. The thesis first describes the installation of the telephone exchange as well as the database. We then focus on the configuration of terminals, the database and writing of Asterisk configuration files. The problems we encountered in this work and their possible solutions are described at the end of this thesis
