Install Zaptel
Zaptel is a set of tools and drivers for the zapata telephony cards. Even if you don’t own a zapata card is wise to install this packages as it also contains a dummy driver that is used for generating clock ticks that asterisk uses for various tasks, example to play sound files or manage conferences.
Zaptel tools are precompiled in Ubuntu and you can install them like this :
apt-get install zaptel
The zaptel kernel modules are distributed as source only and you will need to use some extra tools to get them running:
apt-get install module-assistant m-a prepare m-a get zaptel-source m-a build zaptel If you are using 2.6.28 kernel you have problem with m-a build zaptel! http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=518017 Untar /usr/src/zaptel.tar.bz2 Add this patch http://svn.debian.org/viewsvn/pkg-voip/zaptel/trunk/debian/patches/hrtimer_2628?view=markup&pathrev=6683 Tar the files to /usr/src/zaptel.tar.bz2, run then m-a build zaptel m-a install zaptel modprobe ztdummy
