Long story short.
We been using FreePBX 6.12 for some years.
Just suffered hard disk failure. (Need to pay more attention to warning signs.)
Rebuilt FreePBX with new HDD (WD Enterprise grade)
Applied all updates to latest.
Restored FreePBX from backup (mostly worked).
BUT can’t get Digium TDM400 analog card working.
Hardware is detected by lspci
01:06.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface
Hardware is detected by dahdi_hardware
pci:0000:01:06.0 wctdm- e159:0001 Wildcard TDM400P REV I
To be sure, I’ve renamed /etc/dahdi/genconf_parameters as …/genconf_parameters.original
Not sure what you mean by “battery” in FXO interfaces.
I understand that FXO interface receives “battery” current from the local telco exchange. Yes, I have the FXO port connected to the telco exchange line.
Yes, I have molex power applied, but NO FXS ports connected.
All FreePBX extensions are VOIP and working as intended !
Searching other fora gave me clue to possible hardware issue.
After re-seating the TDM400P in PCI slot, it seems the dahdi driver/s might now be working correctly.
We’ve moved on to next problem with Asterisk Manager.
Unable to connect to Asterisk Manager from /var/lib/asterisk/bin/retrieve_conf, aborting
It looks hardware issue. Make sure you plug the 12V power supply cale if you have FXS on the board. The system has detected the main board, the daught cards missed. maybe you take out the fxs or fxo module and clean agagin and have a try.
