[Asterisk-Users] FXO port on TDM400P hangs!!

[Jared Armstrong]

If this is anything like the issue I have seen on Brooktrout fax cards
it is related to power fluctuations. Is your * system on a properly
sized UPS for the system? What card do you have installed and what
motherboard/PSU are you using?

Hello everyone.

This is a message I've sent before on Sunday, no one replied so I'm
reposting it (guess not everyone's at work 7/7)

I've got this really annoying and beyond-my-knowledge-to-debug problem.
The line connected to my FXO port gets marked "out of order" by my telco
operator. I don't know how to explain this further. If I dial my own
number from a different phone I get a message "the called number is out
of order".

This is only rarely happening (twice on Sunday, once today) but when it
does happen the * requires a reboot! The worst part is that we usually
find of this problem from a customer calling our other number or a
mobile saying the main number can't be reached!

If anyone has any idea where to look or what to look for in the log
files, please advice. If anyone has any workaround for this problem,
again, please advice.

At the moment I'm working on a really ugly solution: I'm planning to
create a call file once every 5 minutes and have * call the hanging
number from the other number. If the call makes it back to the * I'll
set a global var. If the call doesn't make it back to * the global var
will not get set and, when the Dial command times out, I'll know it's
time to System(/sbin/reboot)!
Unfortunately this is really ugly and I'm not sure I'll be able to make
it work, but I will try!
