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

[Cosmin Prund]

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!
