    I have a Sangoma A200 with 2 FXO boards for a total of 4 incoming lines.

    Elastix 1.5.2-2.3 installed.

    The system is up and running. I can make and receive calls.

    if I check the voltage in CLI for the 4 lines I get:

    [code
    ]wanpipemon -i w1g1 -c astats -m 1

    ------- Voltage Status (FXO,port 0) -------

    VOLTAGE : 54 Volts

    ------- Line Status (FXO,port 0) -------

    Line : connected
    [/code]

    Same for the other 3.

    Some times, suddenly I can't make nor receive call anymore.

    If I check the voltage I get:

    [code
    ]wanpipemon -i w1g1 -c astats -m 1

    ------- Voltage Status (FXO,port 0) -------

    VOLTAGE : 1 Volts

    ------- Line Status (FXO,port 0) -------

    Line : connected
    [/code]

    all the four lines show only one Volt and says Line : connected

    Rebooting the machine fixes the problem.

    I understand that if
    Code:
    wanpipemon -i w1g1 -c astats -m 1
    shows 1 Volt is that the line is not connected. Maybe a problem with the cable.

    How can it be that all 4 lines get disconnected at the same time when they are in four different cables?

    Always a reboot fixes the issue.

    Any idea on how troubleshoot it?
