Hi Enrico,
This is a perfect question for Digium support. Just call them and
complain that the card is acting like this.
I was struggling with the same problem about a year ago. Managed to get
my card and FXO modules replaced and that helped a lot.
My problem is still happening like once or twice in a few months, but
now it is much more related if someone would be entering the server room
where my Asterisk box is installed and would touch rack cabinet or
servers or other metal parts. So I think it is now because of static
electricity or poor grounding (hopefully I will have that problem
resolved completely in new office). Digium cards are very very sensitive
to these conditions.
So, just get a new card and/or FXO modules (especially if you purchased
this one more than a year ago, or if you dont know when it was
manufactured).
Other suggestions would be:
- do not disconnect or re-connect phone lines when Asterisk box is up,
do it when server completely powered off
- try to use a different power plug / power outlet for your server
- try to move the server into a different location
- try to fix or install proper power grounding for the power outlets and
prevent anyone from touching the server
Please feel free to contact me off the list, but I dont know if I can
help more.
