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 On 9/23/2011 4:27 AM, Remco Barendse wrote: > 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.
