First off, I recommend using dahdi-linux 2.4.0 *without* compiling dahdi_dummy. A dummy span is no longer needed for DAHDI to provide a timing source to asterisk. But you'll still need crc_ccitt module for dahdi to load, so that doesn't fix the problem as you describe here. If you rebuilt your kernel (which probably wasn't necessary...) you need to reboot into the new kernel, then rebuild DAHDI against your running kernel in order to load. Sounds like you have built DAHDI against one version of the kernel and you're running against another one. Also...make sure you're using "modprobe" and not "insmod" to load the driver...so that crc_ccitt will automatically be loaded as a dependency. For example you can see it automatically loaded here (and how dahdi_dummy isn't needed for timing). ]# lsmod | grep crc_ccitt ]# dahdi_test -c 1 Unable to open dahdi interface: No such file or directory ]# modprobe dahdi ]# lsmod | grep crc_ccitt crc_ccitt 10240 1 dahdi ]# dahdi_test -c 5 Opened pseudo dahdi interface, measuring accuracy... 99.998% 99.981% 99.990% 99.990% 99.991% --- Results after 5 passes --- Best: 99.998 -- Worst: 99.981 -- Average: 99.990100, Difference: 99.990101 ]# Hope this helps, Shaun -- 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?
