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.allstarlink.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
