    I look for a option to read serial numbers from
    Expansion Modules (78914,7915,7916). I found a way to read the phone
    serial numbers with the help of the phone webinterface but there is no way to
    read serials from the connected expansion modules.
    if there a possibility to read serial numbers from expansion modules?
