    The requirements are:
    You need "Microcontroller with support for TCP/IP stack; and Ethernet"

    In one side (the caller), you have to convert your analog signal ( from your analog phones) by using the microcontroller (A to D converter).

    When the analog signal is converted to digital, connect your internet cable from your microcontroller to your Ethernet switch so that the digital signal can be transfered. In this case, you have to write a programming (networking like transfering a file from a client to a server network) to take the digital signal data and transfer it over the internet. On the other side (the receiver), there is another microcontroller taking the digital signal data and transfering back to the analog signal so that the analog phone can understand.

    If someone has any idea how to write a programm to convert analog sigal to digital signal or how to configure the connection between the microcontroller and the ethernet switch or how to transfer the digital signal data over the internet please help. I'm really appreciate your contributions and help. Thank you all and have a nice day!
