[asterisk-users] TDM400 FXO stopped working

[Vladimir Mikhelson]

Remco,

Please try temporarily removing all WCTDM parameters you might have in
/etc/modprobe.d/dahdi.conf.  Then try the same process.  You also may
want to try "service dahdi restart" or equivalent for your distribution.

If none helps I would file a bug report.

Regards,
Vladimir
