The idea behind this project is to use a PC running on Windows 10, to integrate the xampp platform, which contains the PHP language and also mysql server, and this computer must also be connected to an 8-port serial bus, to which they are connected. 8 GSM phones. They are Quectel EC25 cell phones, connected to the t-mobile network. This computer must have installed the open source software Gammu 1.42.0 and its connection to the eight-port bus must also be tested. Once gammu has been tested then the Open Source Web-based SMS Management Kalkun ([login to view URL]) must be installed and tested. Once the Kalkun MSM gateway is tested, then this project will be concluded.
