Lost configuration / red light on card

system · November 25, 2013, 1:28pm

Hello,

Our Asterisk phone server suddenly stopped connecting to the BT box that we have on site.
I called BT (UK ISP) to find out that the service they provide is ISDN30.
They run diagnostics up to that box and it came back fine.
Internal calls (over LAN) are working fine.
The only visible symptom is red light blinking on the ISDN card.
It’s blinking either red/blank or red/green.
I tried swapping the cable and reinserting the card into a different PCI slot but nothing has changed.
We have ordered identical card (model Digium TE110P Wildcard Single Span PCI Card) and swapped it but the problem persists.
So far I couldn’t find any hard evidence of a hardware failure or any other meaningful errors (to me).
I’m suspecting that the existing configuration has been lost somehow.
I don’t seem to be able to retrieve old working one from the backups we have (/etc/asterisk/zapata_custom.conf).

Some info on the server:
