    Hello everyone,
    is there a device that I can connect to my phone line that connects between my modem and incoming phone line to monitor ALL traffic.
    Perhaps a device that splits the iine one the normal going to the modem and the other to an ethernet NIC on my PC?
    Or would it be poss to modify a spare modem routers circuit board to pass all traffic thru to the ethernet line?

    Any help or suggestions would be of great help.
