This message is appearing because, as you pointed out above, you need fxsks=1-16 signalling specified for the FXO modules that are installed on your card. What is the output of dahdi_cfg when the signalling is configured properly? Also, if you're not familiar with dahdi_genconf, you might want to give that a try: $ rm /etc/dahdi/system.conf $ modprobe -r wctdm24xxp $ modprobe wctdm24xxp $ dahdi_genconf system you should have a resonable configuration in /etc/dahdi/system.conf now... $ dahdi_cfg -vvf Because dahdi_cfg is detecting an error in your configuration file, it is *not* attaching the mg2 echo canceller to your channel. I would make sure that dahdi_cfg runs without any errors before starting Asterisk. -- Shaun Ruffell Digium, Inc. | Linux Kernel Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: www.digium.com & www.asterisk.org -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
