    I hope you dont mind me emailing you with a question regarding the configuration of my Asterisk installation.

    I have been all over the internet trying to find an answer but so far haven’t been able to find anything.
    I have Asterisk installed and I can successfully call each extension.

    We have an external Sip gateway which has 4 fxo ports.

    I can not find any information regarding how to get Asterisk to connect to the external sip gateway via an ethernet cable

    Do I need to install a driver?
    I hope you can help

    Many thanks
