Hi everyone. I've installed Asterisk PBX using apt packages, but i don't have actually any Digium card, so i want to use ztdummy. I've tried to modify the Makefiles in the debian source package, i don't get any error, but still the ztdummy module doesn't get compiled. Does anybody has idea how to get the ztdummy module using the debian package system? Thanks for your help.
