Hi Vladimir,
I tried the steps as you wrote them but i just get the same error :
Channel map:
Channel 01: FXO Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 01)
Channel 04: FXS Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 04)
2 channels to configure.
Changing signalling on channel 1 from Unused to FXO Kewlstart
DAHDI_CHANCONFIG failed on channel 1: Invalid argument (22)
Selected signaling not supported
Possible causes:
FXO signaling is being used on a FXO interface (use a FXS
signaling variant)
RBS signaling is being used on a E1 CCS span
Signaling is being assigned to channel 16 of an E1 CAS span
The config i used has been working for years, i wonder what changed.
Thanks!!
Best regards, Remco

Remco,
In my experience something could have gone wrong with the parameters you pass
to WCTDM driver.
You may want to check your /etc/modprobe.d/dahdi.conf
Try loading the driver manually as follows:
1. Stop Asterisk
2. modprobe -r wctdm
3. modprobe wctdm
4. dahdi_cfg -vvv
Good luck,
Vladimir

Hi list
I have 2 servers with a TDM400 card, port 1 populated by an FXO (red)
module), port 4 populated with an FXS module. I am using dahdi linux
and tools 2.5.0.1. The servers are running CentOS 4 and the other box
CentOS 6.
Both modules have been working fine but recently stopped working, when
i start dahdi with just FXS enabled everything is fine.
This is the error i get :
Loading DAHDI hardware modules:
wctdm: [ OK ]
Running dahdi_cfg: DAHDI_CHANCONFIG failed on channel 1: Invalid
argument (22)
Selected signaling not supported

This is in my system.conf :
fxoks=1
echocanceller=mg2,1
# channel 2, WCTDM/4/1, no module.
# channel 3, WCTDM/4/2, no module.
fxsks=4
echocanceller=mg2,4
# Global data
loadzone = nl
defaultzone = nl
When i run dahdi_genconf it doesn't detect the module either :
# Autogenerated by /usr/sbin/dahdi_genconf on Fri Sep 23 11:24:16 2011
# Span 1: WCTDM/4 "Wildcard TDM400P REV E/F Board 5" (MASTER)
# channel 1, WCTDM/4/0, no module.
# channel 2, WCTDM/4/1, no module.
# channel 3, WCTDM/4/2, no module.
fxsks=4
echocanceller=mg2,4
I already replaced both FXO modules with new ones but without result.
Ideas anyone?
