Hello, I'm trying to "modprob ztdummy" in order to use the conferencing feature with Asterisk, but I am having trouble loading it. I am using Gentoo with Kernel 2.6.14 and Asterisk version 1.2.9. I am able to "modprobe zaptel" without a problem, however when I "modprobe ztdummy" I get the error below. FATAL: Error inserting ztdummy (/lib/modules/2.6.14-kororaa-r6/misc/ztdummy.ko): Input/output error FATAL: Error running install command for ztdummy I did read this page: http://www.voip-info.org/wiki/index.php?page=Asterisk%20timer%20ztdummy and checked my Kernel, it is compiled with 'CONFIG_CRC_CCITT=m'. Any help regarding this issue is greatly appreciated. Thanks, Brett ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
