It might help somebody else, I was moving up to version 1.6 from 1.4. I couldn’t find anything on how to uninstall Zaptel so I could start using DAHDI. I ended up doing three steps.
1 - from the old Zap source directory ran the command
make uninstall-modules
2 - I ended up having to edit my modprobe.conf file and removed all the zt… files that were loaded with the ztcfg command.
3 - deleted the zaptel script from the /etc/init.d/ directory
Why they were not removed from the uninstall I’m not really sure, but doing these things I was able to remove zaptel from my machine. I’m sure I shot myself in the foot somewhere but beat it to fit, paint it to match and all is well.
