Asterisk and Radio Over IP Integration at Voice Communication System Air Traffic Control

Asterisk, the most popular open source VoIP core software in telecommunications technology that is integrated with Radio Over IP (RoIP) and Voice over IP (VoIP) gateway devices can be cheap and powerful solution for small airports usually located in rural areas. This paper reports the configuration and implementation of Internet Protocol (IP)-based voice communication system (VCS) for air traffic control using Asterisk VoIP server integrated with MySQL database, Apache webserver and Transceiver Radio PTT devices. The radio gateway that was selected for the prototype did not fulfil several of the chosen requirements, since it was using a different frequency with airport radio frequency standard usage. The prototype is click to call and report via web interface application and allowing 2 way voice communication between Air Traffic Controller (ATC) with airport telecommunication device (PTT Radio Transceiver & telephony). At this report, we will discuss about the prototype of VCS web interface at ATC and communication of Radio Transceiver Device with asterisk VoIP server.
