Fix Zaptel After a Yum Update

Yum, the CentOS package manager, can update your system including the kernel. If you ever done a "yum update" you found out it breaks Asterisk/app_rpt. Here's how to recover from that.

First update Asterisk from SVN. This is the normal update process. While this isn't strictly necessary now is as good a time as any to update.

cd /usr/src
rm -rf astsrc
wget http://x.pttlink.org/svn-trunk.tar.gz -O- | tar xzv
mv trunk astsrc
cd astsrc
make upgrade-acid

Next we update Zaptel. This is the part that actually fixes the problem. (written by Thor N7JCT)

cd /usr/src/astsrc/zaptel
./configure
make
make install
make config
modprobe zaptel
service zaptel start
service asterisk restart
