Keywords:
PABX, Arduino, FreeSWITCH, IVRAbstract
This work presents the design of a PABX (Private Automatic Branch Exchange) using free hardware and software as a technological solution for the automation of telephony in small companies. The design consists of two fundamental parts: an interface card with the PSTN (Public Switched Telephone Network), controlled by Arduino Mega 2560 and configuration software with a graphical user interface that operates on the server. The designed software allows interaction with the hardware, as well as the easy configuration of the FreeSWITCH telephony engine to execute the routing of calls, the creation of IVR (Interactive Voice Response) menus, user management, among other functions. The exchange of information between hardware and software is described using a serial communication protocol designed to carry out the various telephone operations. Finally, it is demonstrated through measurements and tests that the design meets the required functionalities.
