Zaptel Does not compile correctly and is missing calls required by our drivers. This has been observed in this version and appears to be resolved in other versions. If you have the kernel headers, and zaptel installed and linked per our instructions you should be able to simply make and make install. If the dependencies are met and the build fails try a higher or lower version of zaptel and it should clear up.
