I need to build A android app that will permit me to use any smartphone as a telephone switch. It will link GSM and 4G Network on the smatphone to enable a server to call on the gsm network of the smartphone with the app. The server will connect to the smartphone on the 4G and calls true the gsm network the demanded number. All this in a automated and combined process. On one side we are connected true TCP/IP and on the other true GSM and both sides are linked true our softwitch android app.
