A possible way of upgrade WAG54GP2 to support FXO port

    Looks like WAG54GP2 is a great device but without any FXO port for PSTN backup.

    As most other branded products support FXO port which conveniency, my idea is putting a relay in the box which drived by a audion to detect the Internet LED (simpliest) / or to detect a single from processor that an internet is connected and it turn the relay to switch to VoIP. Then power off or loose internet connection, back to the add-on FXO PSTN port.

    Just an idea.
