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?
